FIELD OF THE INVENTION
The present invention relates to mobile robots and, more particularly, to systems and methods including the same.
BACKGROUND OF THE INVENTION
Connectivity (i.e., wireless connection to the Internet and remote clients) has been contemplated for household appliances for some time.
Recently, the term “Internet of Things” has come to represent the idea that household articles of all kinds can be connected to the public Internet. Once connected, such articles can report various data to server and client devices. For example, one idea is to connect ‘smart’ light bulbs to household WAN (Wireless Area Network). Each light bulb would have a microprocessor, memory, some means of detecting or interpreting status, power, and a wireless connection. Using these components, the light bulb can report its status, can be polled, etc.
The concept is broad, and generally is only distinct from household connectivity in general (e.g., computers, cable boxes, media devices, and the like) in that the Internet of Things articles are not normally considered to include sufficient computing resources or communications to meaningfully connect to the public Internet. A conventional refrigerator would not connect to the Internet; the same device as an “Internet of Things” article would include computational, sensor, and communications hardware and sufficient software to become an entity addressable remotely and locally; the expectation being that this Internet Fridge could report its various states (power consumption or the like) and respond to remote commands (increase or decrease internal temperature).
Household mobile robots may also become “Internet of Things” articles. In some ways, household mobile robots are a distinct species within this set—generally, speaking, the autonomy of the household mobile robot sets it apart from other appliances. No other appliance performs in an unpredictable and variable environment. No other appliance makes a multiplicity of autonomous decisions based on tens or hundreds of sensor inputs in order to achieve mission completion.
A dishwasher—even an Internet of Things dishwasher—does not know anything about is contents and runs the equivalent of simple scripts controlling motors and pumps, potentially interrupted by simple clog or other sensors. An iRobot® Roomba® vacuuming robot, during the course of its mission, may detect its own state in numerous ways, and may flexibly escape from challenging situations in the household, as well as engage in predictive and planning activities.
There exist many unmet challenges in the integration of the rich and autonomous behavior of a household mobile robot with the core concepts of “Internet of Things” connectivity.
SUMMARY OF EMBODIMENTS OF THE INVENTION
According embodiments of the present invention, or according to an invention disclosed herein, a mobile robot includes a microprocessor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit. The mobile robot includes driven wheels commandable by the microprocessor to reach a multiplicity of accessible two dimensional locations within a household, and an end effector, including at least one motorized actuator, commandable by the microprocessor to perform mechanical work in the household, the microprocessor executing a plurality of routines. The plurality of routines include a first routine which monitors a wireless local network by communicating with the wireless network circuit, and detects a presence state of one or more network entities on the wireless local network, a second routine which receives a signal from a sensor, the sensor detecting an action state of one of the network entities, the action state changeable between waiting and active, and a third routine which commands the end effector to change state of performing mechanical work based on the presence and on the action state detected by the first and second routines.
In some embodiments, or in an invention disclosed herein, the first routine detects the presence state of a mobile device on the wireless local network, and the second routine receives a signal from a call state sensor in the mobile device, the sensor detecting the call state of the mobile device as the action state, the call state changeable between call readiness and call received. In embodiments, or in an invention disclosed herein, the signal received by the second routine is sent from a monitoring application running on the mobile device. In embodiments, or in an invention disclosed herein, the end effector is the cleaning head of the mobile robot. In embodiments, or in an invention disclosed herein, the third routine commands the cleaning head of the robot to change state of cleaning, based on the presence of the mobile device on the wireless local network and on the call state of the mobile device as the action state.
In embodiments, or in an invention disclosed herein, when the mobile device receives a call, the call state changes from waiting to active. In some embodiments, or in an invention disclosed herein, the state of cleaning is changed from the motorized actuator being powered to off, and in other embodiments, or in an invention disclosed herein, the state of cleaning is changed from the motorized actuator operating full power to operating at a low power, low decibel state. In embodiments, a full power state represents the motorized actuator operating a vacuum fan or a roller element of the cleaning head at full speed and a lower power state represents the motorized actuator operating the vacuum fan or roller element of the cleaning head a lower speed.
In other embodiments, or in an invention disclosed herein, the signal received by the second routine is sent from a sensor on the mobile robot. In some examples, the sensor on the mobile robot is an audio sensor for hearing the call signal. In other examples, the sensor on the mobile robot is a radio receiver for detecting a radio frequency signal indicative of a phone call. In some embodiments, or in an invention disclosed herein, the sensor signaling receipt of a call is a single sensor or a combination of sensors on the mobile device, such as an accelerometer measuring the motion associated with raising a telephonic device to an ear, a proximity sensor for measuring the proximity of the telephonic device to a listener's head, a vibration actuator or sensor for causing or detecting a vibration indicative of a ring, and a microphone on the phone for audibly detecting a ring.
In some embodiments, or in an invention disclosed herein, the first routine detects the presence state of a mobile device on the wireless local network, and the second routine receives a signal from a cleaning readiness sensor in the mobile robot, the sensor detecting the cleaning readiness state of the mobile robot as the action state, the cleaning readiness state changeable between cleaning readiness and cleaning active. In embodiments, or in an invention disclosed herein, the mobile robot executes a monitoring behavior for monitoring the cleaning readiness. In some embodiments, the cleaning readiness is a power charge of the mobile robot, and in other embodiments, the cleaning readiness is a stasis state of the mobile robot. In embodiments, or in an invention disclosed herein, the end effector is the cleaning head of the mobile robot, the cleaning readiness is a stasis state, and the motorize actuator is stationary in a stasis state.
In some embodiments, or in an invention disclosed herein, the third routine which commands the cleaning head of the robot to change state of cleaning based on the presence of the mobile device on the wireless local network and on the cleaning readiness state of the mobile robot as the action state.
One advantage of a mobile robot receiving a signal indicative of the presence of an occupant, as determined by their mobile device appearing on the local network, is that the mobile robot autonomously responds to presence. In some embodiments, the mobile robot independently monitors the local network for the presence of one or more mobile device, and in other embodiments, the mobile device enters the network and notifies the mobile robot of its presence through an application, or set of executable commands running on the mobile device processor for wirelessly communicating instructions to the mobile robot.
The mobile robot will automatically launch and execute a mission, for example, a cleaning mission, if the mobile device is not on the network and the mobile robot ready, for example if a mobile robot battery is charged. The mobile robot will automatically drive away from an occupant, quiet itself, or turn off its power supply to quiet the robot when an occupant takes a phone call. The mobile robot therefore behaves in a smart way by interrupting its mission so that the occupant can hear a caller on the mobile device without background noise interference. In embodiments, or in an invention disclosed herein, the mobile robot retreats from an occupant holding a mobile device or the mobile robot quiets its motorized actuators, such as those for actuating the vacuum fan, those for actuating the drive wheels and those for actuating one or more cleaning head rollers. The mobile robot monitors the call state and, in embodiments, monitors for the radio frequency indicative of a call. When the call has ended, the mobile robot autonomously returns to where it discontinued its mission and completes coverage of that room. The mobile robot, therefore, completes its mission throughout the living space while accommodating for the presence of an occupant and for the receipt of a call on a mobile device.
In some embodiments of the present invention, or in an invention disclosed herein, a mobile robot includes a microprocessor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit. The mobile robot includes driven wheels commandable by the microprocessor to reach a multiplicity of accessible two dimensional locations within a household, and a cleaning head, including at least one motorized actuator, commandable by the microprocessor to perform mechanical work in the household, the microprocessor executing a plurality of routines. The plurality of routines include a first routine which monitors a wireless local network by communicating with the wireless network circuit, and detects a presence state of one or more mobile devices on the wireless local network, a second routine which receives a signal from a call state sensor in a mobile device, the sensor detecting a call state of the mobile device, the call state changeable between call readiness and call received, and a third routine which commands the motorized actuator of the cleaning head to change state of performing mechanical work based on the presence of the mobile device on the wireless local network and on the call state of the mobile device detected by the first and second routines.
In embodiments, or in an invention disclosed herein, the signal received by the second routine is sent from a monitoring application running on the mobile device.
In some embodiments of the present invention, or according to an invention disclosed herein, a mobile robot includes a microprocessor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit. The mobile robot includes driven wheels commandable by the microprocessor to reach a multiplicity of accessible two dimensional locations within a household, and a cleaning head, including at least one motorized actuator, commandable by the microprocessor to perform mechanical work in the household, the microprocessor executing a plurality of routines. The plurality of routines include a first routine which monitors a wireless local network by communicating with the wireless network circuit, and detects a presence state of a mobile device on the wireless local network, a second routine which receives a signal from a cleaning readiness sensor in the mobile robot, the sensor detecting the cleaning readiness state of the mobile robot, the cleaning readiness state changeable between cleaning readiness and cleaning active, and a third routine which commands the cleaning head of the robot to change state of cleaning based on the presence of the mobile device on the wireless local network and on the cleaning readiness state of the mobile robot as detected by the first and second routines.
In embodiments, or in an invention disclosed herein, the mobile robot executes a monitoring behavior for monitoring the cleaning readiness. In some embodiments, or in an invention disclosed herein, the cleaning readiness is a power charge of the mobile robot, and in other embodiments, or in an invention disclosed herein, the cleaning readiness is a stasis state. In embodiments, or in an invention disclosed herein, the end effector is the cleaning head of the mobile robot, the cleaning readiness is a stasis state, and the motorized actuator is stationary in a stasis state.
According to embodiments, or in an invention disclosed herein, a mobile robot includes a microprocessor connected to a memory and a wireless network circuit, for executing routines stored in the memory and commands generated by the routines and received via the wireless network circuit. The mobile robot further includes driven wheels commandable by the microprocessor to reach a multiplicity of accessible two dimensional locations within a household, and an environmental sensor readable by the microprocessor, the microprocessor executing a plurality of routines. The plurality of routines include a first routine which commands the driven wheels to move the robot about the household, a second routine which takes sensor readings at a plurality of the accessible two dimensional locations within the household, and a third routine which, based on the sensor readings throughout the household, sends data to a network entity having a dedicated environmental sensor resulting in the activation of a motorized actuator on the network entity to perform mechanical work in the household, despite the dedicated environmental sensor reading alone determining otherwise.
In embodiments, or in an invention disclosed herein, the mobile robot moves about the household on a primary mission and simultaneously collects environmental sensor readings as a secondary mission. In some embodiments the primary mission is a cleaning mission.
In embodiments, or in an invention disclosed herein, the sensor readings taken at the plurality of accessible two dimensional locations within the household are environmental sensor readings. In some embodiments, the environmental sensor is an air quality sensor, and in other embodiments, the environmental sensor is a humidity sensor. In some embodiments, the environmental sensor is a temperature sensor.
In some embodiments, or in an invention disclosed herein, the network entity is a humidifier.
In some embodiments, or in an invention disclosed herein, the network entity is an air purifier.
In some embodiments, or in an invention disclosed herein, the network entity is a thermostat.
In some embodiments, or in an invention disclosed herein, the sensor readings taken at the plurality of two dimensional locations within the household populate a two dimensional map of sensor readings within the household, the two dimensional map displayed on a human machine interface device in communication with the mobile robot over the network.
In some embodiments, or an invention disclosed herein, the sensor readings taken at the plurality of two dimensional locations within the household populate a three-dimensional map of sensor readings within the household, human machine interface device in communication with the mobile robot over the network.
Network entities, such as thermostats, air purifiers and humidifiers, are stationary and typically located at one or two locations throughout a living space and the stationary sensors therein measure relatively localized air currents at that particular singular, unchanging location. The primary advantage of the mobile robot is accessing locations distant from or in another compartment or room not immediately adjacent the network entities. By mapping measurements throughout a living space, the mobile robot determines whether, based on a single reading taken in a location remote from the network entity or based on an aggregate of readings taken randomly or systematically throughout the living space, a stationary network entity should be activated. Based on a plurality of measurements taken throughout a living space, the mobile robot activates a network entity even when the environmental sensor reading of the network entity indicates otherwise at its singular, unchanging point of location. The network entity's dedicated sensor measures only the immediate volume adjacent the network entity and fails to account for variations in a volume of air mass spread throughout a living space. By monitoring and measuring temperature, air quality and humidity throughout the living space, the mobile robot provides information otherwise inaccessible by the network entity.
In embodiments, or in an invention disclosed herein, a mobile robot includes a controller in communication with a drive system and a processor, the drive system configured to move the mobile robot about a space comprising a plurality of rooms. The mobile robot further includes a memory accessible by the controller, the memory retaining a unique room identifier associated with a room within the space traversed by the mobile robot and an associated score of at least one measurable characteristic associated with the room, the score being calculated by the processor following at least one traversal of the space, and the processor being capable of modifying the score based on changes to the at least one measurable characteristic between traversals of the space or one or more of the plurality of rooms.

In embodiments, or in an invention disclosed herein, a plurality of scores are associated with a unique room identifier and a plurality of onboard robot sensors for measuring the plurality of measurable characteristics. In embodiments, or in an invention disclosed herein, the mobile robot receives one or more sensor measurements from a stationary sensor node with the space, the mobile robot and the sensor node being in wireless communication. In some embodiments, or in an invention disclosed herein, the mobile robot receives an input parameter related to the measurable characteristic and determines an order of a portion or all of the plurality of rooms to traverse based on the input parameter and a score associated with the measurable characteristic of each room.
In some embodiments, or in an invention disclosed herein, the mobile robot further includes at least one localizing sensor that observes sensor readings from objects within the space, for determining a current pose of the mobile robot with reference to the observed objects.

In some embodiments, or in an invention disclosed herein, the at least one measurable characteristic is time to complete cleaning of a room and the sensor is a clock. In some embodiments, or in an invention disclosed herein, the at least one measurable characteristic is mission completion and the sensor is a dirt detect sensor for determining dirtiness of the room relative to other rooms having unique room identifiers based on the score of the dirt detection measurement in each room. In some embodiments, or in an invention disclosed herein, the at least one measurable characteristic is occupancy status, and the sensor is an occupancy sensor. In embodiments, or in an invention disclosed herein, the occupancy sensor is a passive infrared sensor and in some embodiments, or in an invention disclosed herein, the occupancy sensor is an RSSI sensor for determining signal strength of a radio frequency emitted from a mobile device.
Stationary appliances, such as thermostats, air purifiers and humidifiers, are typically located at only one or two locations throughout a living space and the stationary sensors therein measure relatively localized air currents or occupancy status. The primary advantage of the mobile robot is accessing locations distant from or in another compartment or room not immediately adjacent the network entities. By mapping measurements throughout a living space, the robot can calculate a highest reading of measurements or aggregate reading of measurements to calculate a score for the room. By monitoring and measuring throughout the living space, the mobile robot provides information otherwise inaccessible by the stationary appliance. Because the mobile robot makes multiple runs throughout a space, covering one or more room or rooms in each run, the mobile robot is able to learn how long it takes to clean each room individually and how long it takes to clean multiple rooms in the space.
In embodiments, or in an invention disclosed herein, the mobile robot can access the room scores or measured parameters to clean on or more rooms depending on the amount of time available for cleaning. The cleaning time can be received in a request to clean, stored in a cleaning schedule or accessed through native calendar integration over the network. The mobile robot therefore autonomously selects which room or rooms to clean based on the amount of time available and, in some embodiments, or in an invention disclosed herein, based on a score of which room or rooms are the dirtiest. In embodiments, or in an invention disclosed herein, the mobile robot measures the time to clean a room, the occupancy frequency and the dirtiness of the room as represented by a relative score among all the rooms traversed by the robot. In embodiments, or in an invention disclosed herein, the mobile robot measures the time to clean a room, the occupancy frequency or the dirtiness of the room as represented by a relative score among all the rooms traversed by the robot.

The location-responsive environmental control routine correlates the three dimensional array to locations of a plurality of home environmental control nodes, each home environmental control node having a dedicated environmental sensor and a control channel to actuate a motorized actuator to perform mechanical work within the household, and based on a proximity of at least one control node to an environmental mapping location represented in the three dimensional array, sends data to cause the at least one environmental control node to perform mechanical work in the household.
According to an invention or set of inventions disclosed herein, an environmental controller panel (e.g., a thermostat, humidifier controller with humidity sensing, or air purifier with air quality sensing) includes a housing within which are one or more environmental sensors (e.g., electronic thermometer, barometer, humidity or moisture sensor, gas detector such as VOC, CO or CO2, or airborne particulate counter) to provide environmental sensor measurements (e.g., temperature, air pressure, humidity, air quality), and a processor in operative communication with the sensor(s) to receive the environmental sensor measurements. The environmental controller panel is in operative communication with one or more input devices having a user interface (e.g., a local display and input, or a remote user application on a smartphone) for setting or otherwise determining a setpoint environmental quality (e.g., a setpoint temperature, air pressure, humidity, air quality) and an environmental control actuator that performs work (e.g., HVAC, humidity control, and air purifying systems which displace fluids, including air, to effect change in a respective environmental quality toward the setpoint).

Based on, in particular, mapped environmental, floor coverage, and area provided by the mobile robot readings, the model is an a priori stochastic model of human occupancy, such as a Bayesian Network or Markov Model variant, including one or more statistical profiles, based at least in part on geometrical and structural data about the household provided at least in part by the mobile robot readings taken in untethered free space within the living area (i.e., not in fixed positions along walls or in other stationary installations).
In a further adaptation or variation of these inventions including the environmental control panel structure, the mobile robot readings and/or mobile handset remote readings are used to verify, validate, or check a decision made by the environmental control panel based on the stationary environmental quality or occupancy sensors attached to one or more environmental control panels.
According to an additional invention disclosed herein, a method of compensating for local errors caused by direct environmental influence on a control panel operating pursuant to feedback based on an attached environmental sensor includes, comparing a determined ambient environmental measurement taken by the environmental sensor in or on the panel and a setpoint environmental quality, sampling a remote environmental sensor measurement from a roaming or otherwise traveling mobile robot within the household, determining that the measurement(s) from the panel's measurement site are displaced from a similarly representative measurement taken from a plurality of sites within the ambient environment by the mobile robot, and compensating for the displacement by commanding a respective environmental control actuator to perform work to effect a change in the respective environmental quality toward the setpoint at least in part in accordance with the measurement(s) by the mobile robot.

FIGS. 24 and 25 depict embodiments of exemplary communications and data exchanges between nodes according to embodiments of the invention or in an invention herein described.
The hub 110 (FIG. 2) may be any suitable device configured to provide the functionality described herein. In some embodiments, or in an invention disclosed herein, the hub 110 includes a processor 114, memory 115, a Human Machine Interface (HMI) 116, a wireless communications module (e.g., a Wi-Fi module) 112, and an associated antenna 112A. The hub 110 may include connection hardware (e.g., an ethernet connector) for wired connection to the router 162. In some embodiments, or in an invention disclosed herein, the hub 110 includes an integral environmental sensor 121 and/or an integral automation controller device 129. For example, in some embodiments, or in an invention disclosed herein, the hub 110 is a networked, intelligent, microprocessor controlled thermostat including an ambient temperature sensor and an HVAC controller integrated with a processor and, in some embodiments, a battery. Suitable hubs for the hub 110 may include the Iris HubTM available from Lowe's Home Improvement, NESTTM intelligent thermostats available from NEST Labs of Palo Alto, Calif., and devices as disclosed in U.S. Published Application No. 2012/0256009 and U.S. Published Application No. 2012/0066168, the disclosures of which are incorporated herein by reference.
As illustrated, the hub 110 can be connected to the private network 160 by wiring to the router 162. Alternatively, the hub 110 may be wirelessly connected to the router 162 via the wireless module 112 and the WAP 164.
As indicated in the non-exhaustive, exemplary list of FIG. 22 the stationary sensors 120, 122, 124 can be any suitable sensors operable to detect a physical condition or phenomena and convert the same to a corresponding data signal. For example, each sensor 120, 122, 124 may be a temperature sensor, contact sensor, acoustic sensor (e.g., microphone), motion sensor (e.g., passive IR motion sensor), pressure sensor, visible light sensor, moisture sensor, air quality sensor, ultrasonic sensor, or gas composition sensor. Each sensor 120, 122, 124 may include a wireless transmitter (narrowband or broadband/Wi-Fi) to communicate with the hub 110 and/or the private network 160 via the WAP 164. The sensors 120, 122, 124 are stationary in that they remain in one location (e.g., affixed to a wall of the structure 10) throughout the process of monitoring and controlling the environment of the living space 20. In contrast to the mobile robot 200, the stationary sensors 120, 122, 124 must be picked up and transported to relocate and typically will not be relocated at all (i.e., they will typically be permanently installed in a given coordinate location relative to the full coordinate grid mapped to the space 20). While three stationary sensors 120, 122, 124 are shown, the system 100 may include more or fewer.
As indicated in the non-exhaustive, exemplary list of FIG. 22 the automation controller devices 126, 127, 128, 129, 140 may be any suitable devices operable to control operation of a device or system associated with the structure 10. Examples of automation controller devices include a thermostat to actuate/deactuate/adjust the HVAC system 40 (as illustrated, controller 127), a switch device to actuate/deactuate a light (as illustrated, controller 128), an audible alarm, a device operative to open and close a window covering (e.g., automatic shades) (as illustrated, controller 126), an air quality control device 129, such as an air purifier, humidifier, or de-humidifier, a network enabled mobile robot evacuation station dock 140, and an automatic latch or lock device. Each automation controller device 126, 127, 128, 129, 140 may include a wireless transmitter (narrowband or broadband Wi-Fi) to communicate with the hub 110 and/or private network 160 via the WAP 164. While five automation controller devices 126, 127, 128, 129 140 are shown, more or fewer may be provided through out one or more Zones (A-C) in the living structure.
The robot dock 140 may include or be connected to a power supply and include a charger operative to charge a battery of the mobile robot 200 when the robot 200 is effectively docked at the robot dock 140. The dock 140 may be an evacuation station including a motorized receptacle actuatable to empty debris from the robot 200. In some embodiments, or in an invention disclosed herein, the dock 140 is connected (wired or wirelessly) to the private network 160 to enable or facilitate transmission of data from the robot 200 to the private network 160 and/or from the private network 160 to the robot 200. The robot dock 140, therefore, is an example another automation controller device. In embodiments, the robot dock 140 communicates wirelessly directly with the mobile robot 200 through blue tooth, nearfield induction, IR signals or radio.
The mobile robot 200 may be any suitable robot and it will be appreciated that not all of the components, features and functionality described herein are required in all embodiments of an invention disclosed herein, or in an invention disclosed herein. With reference to FIG. 3 the non-exhaustive list of FIG. 22, the exemplary mobile robot 200 includes a chassis 210, a controller 220, memory 222, a battery 224, a battery charger 226, a human-machine interface (HMI) 228, a drive system 230, a mapping/navigation system 240, a service operation system 242 (also referred to herein as “the cleaning system” and the “cleaning head”), a wireless communication system 250, an IR emitter 260, and environmental sensors 270A-J, a debris bin 242A (to store debris collected by a cleaning operation), a bin level sensor 242B, a dirt extraction sensor 242C (to detect the density of characteristics of the debris collected by the cleaning operation), an indicator light 274A, an audio transducer 274B, and a cleaning mode selection switch (e.g., button) 274C. The mobile robot 200 may be generally configured in the manner of or include features from the RoombaTM floor cleaning robot and/or robots as described in U.S. Pat. No. 7,024,278 and U.S. Published Application No. 2007/0250212, the disclosures of which are incorporated herein by reference, with suitable modifications.
The controller 220 may include any suitably configured processor 211 (e.g., microprocessor) or processors. The microprocessor 221 is in communication with the controller 200, memory 22, the cleaning system 242 and drive system 230
The drive system 230 may include any suitable mechanism or system for actively and controllably transiting the robot 200 through the enclosure space 20. According to some embodiments, or according to an invention disclosed herein, the drive system 230 includes a roller, rollers, track or tracks 232 and one or more onboard electric motors 234 (also referred to herein as “motorized actuator”) operable by the controller 220 to convey the robot 200 across the floor of the enclosure space 20.
The service operation system 242 may be optional in some embodiments, or in an invention disclosed herein, and is operable to execute a service operation in the enclosure space 20. According to some embodiments, or according to an invention disclosed herein, the service operation system 242 includes a floor cleaning system that cleans a floor surface of the enclosure space 20 as the robot 200 transits through the space 20. In some embodiments, or in an invention disclosed herein, the service operation system 242 includes a suction head and an onboard vacuum generator to vacuum clean the floor. In some embodiments, or in an invention disclosed herein, the system 242 includes a sweeping or mopping mechanism, such as one or more rotating brushes, rollers, wet or dry stationary or oscillating and/or vibrating cloths or multilayer pad assemblies.
The wireless communication system 250 includes a wireless communication transmitter or module 252 (e.g., a Wi-Fi module) and an associated antenna 254 to enable wireless communication between the robot 200 and the hub 110 and/or the private network 160 (i.e., via the WAP 164). Various different network configurations may be employed for the private network 160, of which the mobile robot 200 constitutes a node. In some embodiments, or in an invention disclosed herein, the robot 200 communicates wirelessly with the hub 110 through the router 162 via the WAP 164. In some embodiments, or in an invention disclosed herein, the mobile robot 200 communicates with the remote management server 150 via the router 162 and the WAP 164, bypassing the hub 110.
In some embodiments, or in an invention disclosed herein, the robot 200 may communicate wirelessly directly with the hub 110 using narrowband or broadband (e.g., Wi-Fi) RF communication. For example, if the robot 200 is not equipped with a transmitter compatible with the WAP 164, the robot 200 may communicate with the hub 110, which may in turn relay data from the robot 200 to the private network 160 or the remote management server 150. In some embodiments, or in an invention disclosed herein, the system 100 includes a network bridge device that receives and converts RF signals from the robot 200 and relays them to the router 162 in a format supported by the router for delivery to the remote management server 150 or another device in the private network 160. In some embodiments, or in an invention disclosed herein, the system 100 includes a low power mesh data network employing a mesh topology wherein RF communications signals are relayed from node to node between the mobile robot 200 and the hub 110. In this case, the stationary sensors 120, 122, 124, the controllers 124, 126, 127, 128, 129, 140 and range extender modules (if any; not shown) may serve as mesh nodes. Likewise, the mobile robot 200 may serve as a node to relay signals between the hub 110 and the other nodes (e.g., devices 120, 122, 124, 126, 127, 128, 129, 140 and range extenders).
As indicated in FIGS. 3 and 22, the exemplary robot 200 includes the following environmental sensors: an IR radiation detector 270A, a camera 270B, an ambient temperature sensor 270C, an ambient light sensor 270D, an acoustic sensor 270E (e.g., microphone), a motion detector 270F (e.g., a passive IR photodiode), an ultrasonic sensor 270G, a pressure sensor 270H, an air quality sensor 270I, and a moisture sensor 270J. These sensors are not exhaustive of the types of sensors that may be provided on the robot 200 and certain of the sensors may be omitted depending on the environmental parameters to be detected by the robot 200.
The mapping/navigation system 240 can be used by the mobile robot 200 to map the enclosure space 20 and to determine or register the position of the robot 200 relative to the space 20 (i.e., to localize the robot 200 in the space 20). The robot 200 can thus also localize the locations of its onboard sensors 270A-J. Any suitable technique and components may be used to localize and register the robot 200, such as machine vision (e.g., using the camera 270B and Feature Recognition or Class Recognition software), light beacons, or radiofrequency received signal strength indicator (RSSI) technology.
According to some embodiments, or in according to an invention disclosed herein, the mobile robot 200 or system 100 can uniquely identify rooms (e.g., Zone A, Zone B, Zone C) by combining (1) identity information (e.g., the IPv6 identity of an “Internet of Things” 6LowPan light bulb or socket transceiver, plug unit, or the like), (2) RSSI (e.g., the signal strength/amplitude of the same nearby IPv6 RF transceiver) and (3) remote control (e.g., the ability to modulate that RF transceiver via the local network or internet). For example, the autonomous robot 200 (e.g., a Roomba® robot) can navigate a room (e.g., Zone A, Zone B, or Zone C) until it finds a peak signal strength of an IPv6 transceiver, in which case it can be expected to be nearest this transceiver. It can then tag this transceiver with a topological or Cartesian location. Should the transceiver be associated with a room identity by an end user or automatically via any means (e.g., “living room light bulb No. 3”), the robot 200 can use this information in various ways. For example, the robot 200 may be commanded to clean the living room, in which case it can use its mobility and distance-dependent variation in signal strength to home on this room (even without a map). As another example, a robot 200 can be commanded to clean only the living room, in which case one or more transceivers known to be in the living room “anchor” the robot 200 to that room. The robot 200 sets a threshold for signal strength and/or rough localization using multiple signal sources and/or identifiable walls and doorways, and covers the room such that the signal strength of the living room IPv6 6LowPAN light bulb is high.
The mobile robot 200 can identify a room or Zone (A-C) in a number of different ways, independent of the system 100. In an embodiment, or in an invention disclosed herein, the mobile robot 200 may visually recognize one or more features located in one room using its camera 270B. In an embodiment, or in an invention disclosed herein, the mobile robot 200 can identify a room or Zone (A-C) using its mapping and navigation system 240 to identify coordinates within a defined room.
Further methods and operations in accordance with embodiments of an invention disclosed herein, or in accordance with an invention disclosed herein, and utilizing the environmental management system 100 will now be described.
According to some methods, the system 100 uses data from one or more of the networked stationary sensors 120, 122, 124 to control or enhance operation of the mobile robot 200. In some embodiments, or in an invention disclosed herein, the sensors 120, 122, 124, are occupancy sensors (e.g., passive IR motion detectors). When the sensors 122 detect a person P in a given zone A-C, the system 100 will cause the robot 200 to alter its operation to adapt to the occupancy. In embodiments, or in an invention disclosed herein, the mobile robot 200 detects a person P based on a signal from an occupancy sensor, heat sensor, RSSI sensor, or a signal indicating the presence of the person's local user terminal 142 (also herein referred to as “mobile device 300”). For example, the robot 200 may be executing a floor cleaning operation and the system 100 (e.g., via instructions from the hub 110 to the robot 200) may instruct the robot 200 to return to the dock 140, move to a different, unoccupied zone, avoid the occupied zone, or assume a quieter mode of operation. Similarly, before deploying the robot 200, the system 100 can use the stationary sensors 122 to determine whether an occupant is detectable and, if not, clear the robot 200 to proceed with a mission (e.g., a floor cleaning excursion).
Alternatively, one or more of the onboard sensors 270A-J may detect occupancy and the robot 200 may communicate this information to the hub 110 for further instruction regarding mission completion or truncation. In embodiments, or in the invention, the mobile robot 200 receives a signal indicating the presence of the person's mobile device on the WAP 164. The signal may be detected by the mobile robot 200 monitoring the wireless local network 160 or a robot manager access client 152A operating on the mobile device 300 may execute a routine that sends a signal to the mobile robot 200 indicating that the mobile device 300 is on the WLAN 160 and accessing the WAP 164. In embodiments, or an invention disclosed herein, the mobile robot 200 may include a radio receiver capable of detecting a call on the mobile device 300, the active call putting the mobile device 300 in an active call state 300A. In embodiments, or in an invention disclosed herein, the mobile robot may detect the strength of the call signal with an RSSI sensor. When the mobile device 300 is in an active call state 300A, the mobile robot controller 120 will alter a state of the mobile robot 200 to respond to the call signal by returning to the dock 140, moving to a different, unoccupied zone (A-C), avoid the occupied zone (A-C), or assume a quieter mode of operation. In embodiments, or an invention disclosed herein, an occupied zone (A-C) is a zone in which a person P or mobile device 300 is present. In embodiments, or an invention disclosed herein, an occupied zone is a zone in which a mobile device 300 is in an active call state 300A.
In some embodiments, or in an invention disclosed herein, the system 100 can automatically control devices 120, 122, 124, 126, 128, 129, 140 of the structure 10 to facilitate operation of the robot 200. For example, the system 100 (e.g., via instructions from the hub 110) can automatically turn on a light fixture 34 using a controller 128 to illuminate a region viewed by the camera 270B of the robot 200. The robot manager access client 152A may instruct the mobile robot 100 to return to the dock 140 when a person P returns to the living structure 10 after being outside of the WLAN range 165. The robot manager access client 152A may instruct the mobile robot 100 to operate in a quiet mode when a person P returns to the living structure 10 after being outside of the WLAN range 165 and the mobile device 300 on the WLAN 164 receives a call and is in an active call state 300A (also referred to herein as a “call” or “ring”). The active call state 300A refers to a call ringing on a mobile device 300A and also to an occupant answering the call 300A.
As indicated in FIGS. 3, 4 and 21, in one embodiment, or in an invention disclosed herein, the microprocessor 221 of the mobile robot 200 executes a plurality of routines. The plurality of routines include a first routine which monitors the wireless access point (WAP) 164 by communicating with the wireless network circuit 250, and detects a presence state of one or more mobile devices 300 within the WLAN range 165. A second routine receives a signal from a sensor, the sensor detecting a call state of the mobile device 300, the action state changeable between call readiness and call received. A third routine commands a motorized actuator of the service operation system 242 of the mobile robot 200 to change state of performing mechanical work based on the presence of the mobile device 300 on the WLAN and on the call state detected by the first and second routines.
As described above, in some embodiments, or in an invention disclosed herein, the state of cleaning is changed from the motorized actuator of the service operation system 242 being powered to off, and in other embodiments, or in an invention disclosed herein, the state of cleaning is changed from the motorized actuator operating at full power to operating at a low power, low decibel state. In embodiments, a full power state represents the motorized actuator operating a vacuum fan or a roller element of the service operation system 242 at full speed and a lower power state represents the motorized actuator operating the vacuum fan or roller element of the service operation system 242 a lower speed.
In other embodiments, or in an invention disclosed herein, the signal received by the second routine is sent from a sensor 270A-J on the mobile robot 200. In some examples, the sensor 270A-J on the mobile robot 200 is an audio sensor 270E for hearing the call ring or vibrate 300A. In other examples, the sensor 270A-J on the mobile robot 200 is a radio receiver of the wireless communication system 250 for detecting a radio frequency signal indicative of a phone call 300A, such as, for example, 915 mHz in North America or 868 MHz in Europe. In some embodiments, or in an invention disclosed herein, the sensor signaling receipt of a call 300A is a single sensor or a combination of sensors on the mobile device 300, such as an accelerometer measuring the motion associated with raising a telephonic device to an ear, a proximity sensor for measuring the proximity of the telephonic device to a person's P face or head, a vibration actuator or sensor for causing or detecting a vibration indicative of a ring 300A, and a microphone on the phone for audibly detecting a ring 300A.
In some embodiments, or in an invention disclosed herein, the first routine detects the presence state of a mobile device 300 on the wireless local network, and the second routine receives a signal from a cleaning readiness sensor in the mobile robot 200, the sensor detecting the cleaning readiness state of the mobile robot 200, the cleaning readiness state changeable between cleaning readiness and cleaning active. In embodiments, or in an invention disclosed herein, the mobile robot 200 executes a monitoring behavior for monitoring the cleaning readiness. In some embodiments, the cleaning readiness is a power charge of the battery 224 of the mobile robot 200, and in other embodiments, the cleaning readiness is a stasis state of the mobile robot 200. In embodiments, or in an invention disclosed herein, the end effector is the cleaning head or service operation system 242 of the mobile robot 200, the cleaning readiness is a stasis state, and the motorized actuator is stationary in a stasis state.
In some embodiments, or in an invention disclosed herein, the third routine which commands the cleaning head or service operation system 242 of the mobile robot 200 to change state of cleaning based on the presence of the mobile device 300 on the wireless local network and on the cleaning readiness state of the mobile robot 200. If the mobile robot does not have enough battery charge to power a mission, the mobile robot 200 will not launch even when the occupancy schedule indicates a time interval during which the occupant(s) are away from the living structure 10.
In some embodiments, or in an invention disclosed herein, the network-enabled mobile device that enables the mobile robot 200 to detect occupancy presnese is a wireless transmission enabled sensor tag, such as the Sen.seTM motion cookie. In other embodiments, or in an invention disclosed herein, the mobile device is a smartphone 300. In some embodiments, the mobile device is a wireless transmission enabled device, such as a portable activity tracker, baby monitor, scale or air quality monitor. Examples of such wired mobile devices are the WithingsTM activity monitor, baby monitor, and scale. In some embodiments, or in an invention disclosed herein, the mobile robot 200 uses an onboard camera 270B or passive IR sensor 260 to detect the presence of one or more occupants P in one or more rooms (Zones (A-C)) in the enclosure space 20.
One advantage of a mobile robot receiving a signal indicative of the presence of an occupant P, as determined by their mobile device 300 appearing on the WAP 164, is that the mobile robot 200 autonomously responds to presence. In some embodiments, the mobile robot independently monitors the local network 160 for the presence of one or more mobile devices 300, and in other embodiments, the mobile device 300 enters the network and notifies the mobile robot 200 of its presence through an application, such as the robot manager access client 152 or the environmental manager access client 152 running on the mobile device processor for wirelessly communicating instructions to the mobile robot 200.
The mobile robot 200 will automatically launch and execute a mission, for example, a cleaning mission, if the mobile device 300 is not on the network and the mobile robot ready, for example if a mobile robot battery 244 holds a charge. The mobile robot 200 will automatically drive away from an occupant P, quiet itself, or turn off its power to quiet the mobile robot 200 when an occupant P takes a phone call 300A. The mobile robot 200 therefore behaves in a smart way by interrupting its mission so that the occupant P can hear a caller on the mobile device 300 without background noise interference. In embodiments, the mobile robot retreats from an occupant P holding a mobile device 300 or the mobile robot quiets its motorized actuators, such as those for actuating the vacuum fan, those for actuating the drive wheels 232 and those for actuating one or more cleaning head rollers of the service operation system 242. The mobile robot 200 monitors the call state and, in embodiments, monitors for the radio frequency indicative of a call 300A. In embodiments, or in an invention disclosed herein, when a call has ended, the mobile robot 200 autonomously returns to where it discontinued its mission and returns to an active mission state. The mobile robot 200, therefore, completes its mission throughout the enclosure space 20 while accommodating for the presence of an occupant P and for the receipt of a call 300A on a mobile device 300. According to some embodiments, or in according to an invention disclosed herein, the system 100 uses data collected by the environmental sensors of the mobile robot 200 to enable or enhance the monitoring and/or control functions and processes of the system 100. The robot environmental sensors 270A-J (which are networked to the hub 110 and/or the remote management server 150) can thereby be used in place of or in addition to the stationary sensors 120, 122, 124 to provide input data and instructions to the hub 110, the mobile device 300, the networked-enabled stationary sensors 120, 122, 124, the networked-enabled automation controller devices 126, 127, 128, 129, 140 and/or the remote management server 150. As discussed above, the locations of the robot environmental sensors 270A-I in the enclosure space 20 can be determined and registered so that the readings from the robot environmental sensors 270A-J can be correspondingly registered with respect to the space 20.
The ambient light sensor 270D or camera 270B, for example, can be used to detect the light level in a zone and/or entering through a window 30. Based on the data from this sensor robot or sensors, the system 100 may use a controller 126 to close a shade 30A on the window or notify a user that the shade should be closed.
Similarly, the camera 270B or other sensors on the robot 200 can be used to detect open windows 30 or doors 32. In this manner, the robot 200 can monitor portals to and zones of the enclosure space for security or other purposes.
As indicated in FIGS. 3, 22, 26 and 27 the temperature sensor 270C can be used to detect an ambient temperature at a location in the space 20 other than the location(s) of the stationary temperature sensor(s) 110. In this way, the mobile robot 200 obtains a temperature data set that more accurately reflects the temperature distribution in the space 20. The system 100 may respond by modifying operation of the HVAC system 40 or other devices (e.g., automatically opening or closing thermal shades) or reporting the temperature distribution to a user. As indicated in FIG. 26, the mapping and navigation routine enables the mobile robot 200 to measure and store sensor temperature readings 605 throughout the enclosure space 20 to create 2 dimensional or 3 dimensional map of temperature readings 605 throughout the enclosure space 20. Similarly, in embodiments, or in an invention disclosed herein, the mobile robot 200 measures and stores air quality readings 610 with its onboard air quality sensor 270I as the mobile robot 200 drives along a robot path 620 throughout the enclosure space 20. The air quality readings 610 are mapped to a 2 dimensional or 3 dimensional map of air quality readings throughout the enclosure space 20. In embodiments, or in an invention disclosed herein, the air quality readings 610 may measure commonly detected air quality values, such as those for Common air pollutants, particulate matter (PM), sulphur oxides (SOx), nitrogen oxides (NOx), volatile organic compounds (VOCs), carbon monoxide (CO) and ammonia (NH3), ground-level ozone (O3), pollen, dust, or other particulate matter. In embodiments, or in an invention disclosed herein, the air quality readings measure humidity. As indicated in FIG. 26, in embodiments, or in an invention disclosed herein, the map 600 of sensor readings 605, 610 displays to the HMI of a local user terminal 142, 300 or a remote user terminal 144, 300 for active management of the networked-enabled stationary sensors 120, 122, 124 and the networked-enabled automation controller devices 126, 127, 128, 129, 140. In embodiments, or in an invention disclosed herein, the mobile robot 200 processes the mapped sensor readings 605, 610 to send operational instructions the networked-enabled stationary sensors 120, 122, 124 and the networked-enabled automation controller devices 126, 127, 128, 129, 140. As indicated in FIGS. 26 and 27, the system 100 therefore uses a mapping mobile robot 200 to collect thermal/humidity/air quality data and assemble a dynamically updated two dimensional map 600 or three dimensional map 700 which can be used for home environmental control.
In some embodiments and according to a first aspect, or according to an invention disclosed herein, a household mobile robot 200 for “coverage” missions (sweeping, vacuuming, mopping, spreading fluid, and/or any combination of these) uses a suitable technique or techniques, in some embodiments, or in an invention disclosed herein, “Simultaneous Localization and Mapping” (SLAM) techniques, to generate a map of the surface being, for example, vacuumed. There are various techniques, and various maps that may be generated. Maps may be topological, Cartesian, polar, representational, probabilistic, or other; and/or may track walls, obstacles, open spaces, fiducials, natural features, “occupancy”, or other map features. In some techniques, many maps, each of some degree of probable correctness, are recorded.
According to some embodiments, or according to an invention disclosed herein, substantive processing of the environmental sensor data collected by the robot 200 as described herein is conducted entirely or primarily by the microprocessor 221 of the robot 200. According to some embodiments, or according to an invention disclosed herein, substantive processing of the environmental sensor data collected by the robot 200 as described herein is conducted entirely or primarily remotely from the robot 200. In some embodiments, or in an invention disclosed herein, said processing is conducted entirely or primarily at the cloud or remote management server 150. In some embodiments, or in an invention disclosed herein, said processing is conducted entirely or primarily at the remote user terminal 144, 300 or local user terminal 142, 300. However, in other embodiments, or in an invention disclosed herein, all or a portion of the processing of the robot sensor data may occur in the hub 110.
As indicated in FIGS. 3, 21, 23, 26 and 27 according to embodiments, or in an invention disclosed herein, the mobile robot 200 includes a microprocessor 221 connected to a memory 222 and a wireless network circuit 160, for executing routines stored in the memory 222 and commands generated by the routines and received via the wireless network circuit 160. The mobile robot 200 further includes driven wheels 232 commandable by the microprocessor 221 to reach a multiplicity of accessible two dimensional locations within an enclosure space, 20, or household, and an environmental sensor 270C, 270I, 270J readable by the microprocessor 221, the microprocessor 221 executing a plurality of routines. The plurality of routines include a first routine S2501 which commands the driven wheels 232 to move the mobile robot 200 about the household 20, a second routine S2505 which takes sensor readings 605, 610 at a plurality of the accessible two dimensional locations within the household 20, as indicated in the exemplary map 600 of FIG. 25, and a third routine S2515 which, based on the sensor readings 605, 610 throughout the household 20, sends data to a the networked-enabled automation controller devices 126, 127, 128, 129, 140 having a dedicated environmental sensor 120 resulting in the activation of a motorized actuator 41 on the networked-enabled automation controller devices 126, 127, 128, 129, 140 to perform mechanical work in the household 20, despite the dedicated environmental sensor alone determining otherwise.
In embodiments, or in an invention disclosed herein, the mobile robot moves about the household 20 on a primary mission and simultaneously collects environmental sensor readings 605, 610 as a secondary mission. In some embodiments, the mobile robot 200 is a vacuum and the primary mission is a cleaning mission. While the mobile robot 200 moves about the household 20 vacuuming, it also measures and maps environmental sensor readings 605, 610.
In embodiments, or in an invention disclosed herein, the sensor readings 605, 610 taken at the plurality of accessible two dimensional locations within the household 20 are environmental sensor readings. In some embodiments, the environmental sensor is an air quality sensor 270I, and in other embodiments, the environmental sensor is a humidity sensor 270J. In some embodiments, the environmental sensor is a temperature sensor 270C.
In some embodiments, or in an invention disclosed herein, the networked-enabled automation controller device 129 is a humidifier with a dedicated humidity sensor 120. In some embodiments, or in an invention disclosed herein, the networked-enabled automation controller device 129 is an air purifier with a dedicated air quality control sensor 120. In some embodiments, or in an invention disclosed herein, the networked-enabled automation controller device 129 is a thermostat 110 for controlling automation elements such as HVAC 40 and automated window shades 30A.
Networked-enabled automation controller devices 110, 126, 127, 128, 129, 140 such as thermostats, air purifiers and humidifiers, are stationary and typically located at one or two locations throughout an enclosure space 20 and the stationary sensors therein measure relatively localized air currents at that particular singular, unchanging location. The primary advantage of the mobile robot 200 is accessing locations distant from or in another room or Zone (A-C) not immediately adjacent the stationary networked-enabled automation controller devices 110, 126, 127, 128, 129, 140. By mapping measurements throughout an enclosure space 20, the mobile robot 200 determines whether, based on a single reading 605, 610 taken in a location remote from the stationary networked-enabled automation controller devices 110, 126, 127, 128, 129, 140 or based on an aggregate of readings taken randomly or systematically throughout the enclosure space 20, a stationary networked-enabled automation controller device 110, 126, 127, 128, 129, 140 should be activated.
Based on a plurality of measurements taken throughout an enclosure space 20, the mobile robot 200 activates a networked-enabled automation controller device 110, 126, 127, 128, 129, 140 even when the environmental sensor 120 reading of the networked-enabled automation controller device 110, 126, 127, 128, 129, 140 indicates otherwise at its singular, unchanging point of location on the map 600. The network entity's dedicated sensor 120 measures only the immediate volume adjacent the networked-enabled automation controller device 110, 126, 127, 128, 129, 140 and fails to account for variations in a volume of air mass spread throughout an enclosure space 20. By monitoring and measuring temperature, air quality and humidity throughout the enclosure space 20, the mobile robot 200 provides information otherwise inaccessible by the stationary networked-enabled automation controller device 110, 126, 127, 128, 129, 140. As shown in the exemplary map 600 of FIG. 25, the mobile robot 200 can measure temperature variations in different zones (A-C) of an enclosure space 20, identifying on the map 600 hot spots and high pollen readings (i.e. low air quality) near a drafty window, for example. As shown in the exemplary map 700 of FIG. 27, the mobile robot 200 can measure temperature variations in different zones (A-C) of an enclosure space 20, identifying on the map 700 temperature ranges in a topographical presentation.
If the mobile robot 200 is on a sensor reading mission as the primary mission and is not conducting a secondary mission, such as a cleaning mission, the mobile robot 200 may send a command signal to a stationary networked-enabled automation controller device 110, 126, 127, 128, 129, 140 at different stages of the robot mission. In one embodiment, or in an invention disclosed herein, once the mobile robot 200 takes a single sensor reading falling above or below an acceptable threshold level or range for temperature, humidity or air quality, the mobile robot 200 instructs the corresponding stationary networked-enabled thermostat 110 or air purifier or humidifier 129 to operate even if the dedicated sensor 120 on the stationary networked-enabled automation controller device 110, 126, 127, 128, 129, 140 falls within the acceptable threshold measurement or range of measurements. In one embodiment, or in an invention disclosed herein, once the mobile robot 200 finishes its mission, it averages its sensor readings. If the average sensor reading for a room or Zone (A-C) falls above or below an acceptable threshold level or range for temperature, humidity or air quality, the mobile robot 200 instructs the corresponding stationary networked-enabled thermostat 110 or air purifier or humidifier 129 to operate even if the dedicated sensor 120 on the stationary networked-enabled automation controller device 110, 126, 127, 128, 129, 140 falls within the acceptable threshold measurement or range of measurements. In one embodiment, or in an invention disclosed herein, once the mobile robot 200 takes a single sensor reading falling above or below an acceptable threshold level or range for temperature, humidity or air quality, the mobile robot 200 finishes its mission and then instructs the corresponding stationary networked-enabled thermostat 110 or air purifier or humidifier 129 to operate even if the dedicated sensor 120 on the stationary networked-enabled automation controller device 110, 126, 127, 128, 129, 140 falls within the acceptable threshold measurement or range of measurements.
As indicated in FIGS. 26 and 27, according to an embodiment, or in an invention disclosed herein, a mobile robot 200 includes an environmental sensor readable by the microprocessor 221 to take current readings of an environmental quality. The mobile robot 200 additionally includes a localizing circuit, with at least one localizing sensor, such as a camera 270B, that observes sensor readings from objects within the household 200, for determining a current pose of the mobile robot 200 with reference to the observed objects. The microprocessor execute a plurality of routines including a navigation routine which commands the driven wheels 232 to move the robot 200 about the household 20, a surface mapping routine that accumulates observations from the localizing circuit to record a two dimensional array representing possible locations of the mobile robot 200, an environmental mapping routine that takes and accumulates readings from the environmental sensor at a plurality of the accessible two dimensional locations within the household and causes the memory 222 to store a three dimensional array based on the readings and on the two dimensional array representing possible locations of the mobile robot; and a location-responsive environmental control routine. The location-responsive environmental control routine correlates the three dimensional array to locations of a plurality of control nodes, such as the networked-enabled automation controller devices 110, 126, 127, 128, 129, 140. Each control node, or networked-enabled automation controller device 110, 126, 127, 128, 129, 140, has a dedicated environmental sensor 120 and a control channel to actuate a motorized actuator 41 to perform mechanical work within the household 20. Based on a proximity of at least one control node, or networked-enabled automation controller device 110, 126, 127, 128, 129, 140, to an environmental mapping location represented in the three dimensional array, the mobile robot 200 sends data to cause the at least one environmental control node, or networked-enabled automation controller device 110, 126, 127, 128, 129, 140, to perform mechanical work in the household 20.
One or more of the robot sensors 270A-J may be used to sense an occupant in the enclosure space 20. The mobile robot 200 can significantly improve the occupancy detection capability of the system 100 by providing occupancy data at a location or locations that are not available to the stationary sensors 110, 120, 122, 124. The occupancy information collected by the robot 200 may be used alone or to supplement occupancy information collected by one or more of the stationary sensors 110, 120, 122, 124. Sensors on the robot 200 can be used to detect environmental conditions and collect occupancy data in support of occupancy sensing systems as disclosed in U.S. Published Application No. 2012/0066168 (the disclosure of which is incorporated herein by reference), for example.
According to some embodiments, or according to an invention disclosed herein, the mobile robot 200 determines whether an electronic device is turned on and, if so, automatically turns off the electronic device. In some embodiments, or in an invention disclosed herein, the robot 200 detects that the TV 36 is on (e.g., using the camera 270B or a radiation sensor 270A, 270D) and responds thereto by turning the TV 36 off (e.g., using the IR modulator 260) or notifying the hub 110, which turns the TV 36 off (e.g., using controller 126).
According to some embodiments, or according to an invention disclosed herein, the system 100 uses environmental information collected by the robot sensors 270A-J for energy management execution, planning and/or reporting. The system 100, using sensor data from the robot 200, can determine that an automated control response is needed and initiate the response. The system 100 using sensor data from the robot 200 therefore monitors human occupancy behaviors and make suggestions for improving energy efficiency.
For example, the system 100 may determine from data acquired by the camera 270B that the window shade 30A should be closed to block out light and actuate the controller 126 to close the shade 30A. By way of further example, the robot 200 can detect that a light 34 is on at a time or under conditions when it should not be and the system 100 can respond thereto by actuating a controller 126 to turn off the light 34. In some configurations, the system 100 may notify the user (e.g., via the terminal 142 or the terminal 144) that action may be needed (e.g., close the shade or turn off the light) rather than automatically executing the action. In this case, the system 100 may be configured to enable the user (e.g., via the terminal 142, 144) to instruct the system 100 to execute the desired action. Regardless of how the action is executed, directly by a user or indirectly via the system 100, the robot 200 uses the sensors 270A-J to confirm (e.g. visual confirmation with an onboard camera) that a desired action is completed (e.g. light turned off, shades drawn, door shut, storm window lowered, etc.).
According to some embodiments, or according to an invention disclosed herein, the system 100 is configured to evaluate the data from the environmental sensors (including the robot sensors), generate a usage report, energy management plan, proposal or recommendation based on the data, and report the report, plan, proposal or recommendation to a user (e.g., at the terminal 142, the remote terminal 144, the hub 110, the robot 200 or otherwise).
In some embodiments, or in an invention disclosed herein, the system 100 collects device usage data, determines a pattern of device usage, generates a recommendation plan for operating or deploying energy management equipment, and reports the recommendation or plan to the user. For example, the system 100 may monitor the statuses (on or off) of the light bulbs and recommend to the user that the user program the system 100 or purchase and install certain home automation equipment (e.g., light controllers or IP addressed light bulbs (e.g., IPv6 addressed LED light bulbs available from Greenwave Reality) to automatically turn certain of the lights on and off. The system 100 may plan a deployment strategy for networked energy management equipment. The system 100 can report the user's behavior patterns and suggest priority for adding different automated elements to the network.
The system 100 may provide the user with Internet URL links to webpages describing equipment recommended for addition to the system and/or to webpages for purchasing such equipment.
The robot 200 can use an onboard sensor (e.g., the IR detector 270A or a photodiode) to assess whether a lamp (e.g., an incandescent light bulb) has burned out or is near its end of life and will soon burn out and, if so, the system 100 can send the user a message reporting the same. The message may include an Internet link to a webpage where a replacement lamp can be purchased. For example, in one embodiment, or in an invention disclosed herein, the robot 200 includes a photodiode for sensing the frequency component of light.
The mobile robot 200 may be used to charge (in some embodiments, or in an invention disclosed herein, wirelessly (inductively)) a battery 120A of one or more of the stationary sensors 120, 122, 124, the controllers 126 and the hub 110 using the charger 226. One or more of the components 120, 122, 124, 126, 110 may be configured and used to charge (e.g., wirelessly) the battery 224 of the robot 200 and/or the robot 200 may be charged by the dock 140.
In embodiments, or in an invention disclosed herein, the mobile robot 200 monitors human occupancy behaviors and autonomously makes decisions about operating such as when to operate and for how long, which may depend on user preferences. The mobile robot 200 can learn the layout of an enclosure space 200 and the amount of time it takes to complete coverage of each room or Zone (A-C) in the enclosure space 20 and use that stored information to plan full coverage missions or mini missions of one or more rooms whose coverage times, alone or in combination, fall within a scheduled run time. In embodiments, or in an invention disclosed herein, the mobile robot 200 can access an occupancy schedule to determine a launch time. In embodiments, or in an invention disclosed herein, the occupancy schedule may be directly input to the mobile robot 200 thought an HMI 228 on the mobile robot 200 or wirelessly accessed through the LAN 160. In embodiments, or in an invention disclosed herein, the occupancy scheduled may be wirelessly downloaded to the memory 222 of the mobile robot 200 through native calendar integration. In embodiments, or in an invention disclosed herein, the mobile robot 222 therefore plans a complete mission or mini mission that ends before occupants arrive. In embodiments, or in an invention disclosed herein, the mobile robot 22 therefore plans when to preheat an oven or turn the thermostat up or down to achieve even heating or cooling throughout the enclosure space when occupants are away or when they are scheduled to return.
In one embodiment, or in an invention disclosed herein, the mobile robot 200 moves about the living space 20 through a multiplicity of accessible two dimensional locations within a the living space 20 (also referred to herein as “household”). The mobile robot 200 includes a localizing circuit, with at least one localizing sensor that observes sensor readings from objects within the household 20, for determining a current pose of the mobile robot 200 with reference to the observed objects, the microprocessor 221 executing a plurality of routines. The plurality of routines include, a navigation routine which commands the driven wheels 232 to move the mobile robot 200 about the household 20, a surface mapping routine that accumulates observations from the localizing circuit to record a two dimensional array representing possible locations of the mobile robot 200, a mission time estimate routine that accumulates timed readings from the localizing circuit and determines at least one estimated completion time span for the mobile robot 200 to substantially cover a surface area of the household 20 corresponding to a contiguous set of possible locations within the two dimensional array, and a mission pre-planning routine that compares a target completion time to the at least one estimate completion time span, and commands the driven wheels 232 to begin covering a the surface area sufficiently in advance of the target completion time for the at least one estimated completion time to pass, so that the surface area is substantially covered before the target completion time.
In embodiments, or in an invention disclosed herein, the mission pre-planning routine further comprising identifying a target completion time and launching the robot 200 autonomously based on knowing an occupancy schedule of the household 20. In embodiments, or in an invention disclosed herein, the mobile robot 200 monitors and learns the occupancy schedule over a period or periods of time and sets the target completion time based on the learned occupancy schedule. In some embodiments, the mobile robot learns the occupancy schedule over a period of time and identifies one or more occupancy patterns and sets the target completion time based on the one or more learned occupancy patterns.
In some embodiments and according to a first aspect, or according to an invention disclosed herein, the mobile robot 200 for “coverage” missions (sweeping, vacuuming, mopping, spreading fluid, and/or any combination of these) uses a suitable technique or techniques, in some embodiments, or in an invention disclosed herein, “Simultaneous Localization and Mapping” (SLAM) techniques, to generate a map of the surface being, for example, vacuumed. There are various techniques, and various maps that may be generated. Maps may be topological, Cartesian, polar, representational, probabilistic, or other; and/or may track walls, obstacles, open spaces, fiducials, natural features, “occupancy”, or other map features. In some techniques, many maps, each of some degree of probable correctness, are recorded.
In some embodiments, or in an invention disclosed herein, the environmental sensor data from the robot sensors 270A-J is sent to the hub 110, which in turn forwards the robot sensor information, or information derived from the robot sensor information, to the remote management server 150 for computation. The remote management server 150 will then send a report or recommendation to the user (e.g., at a terminal 142, 144, 300) based on the computation.
In some embodiments, or in an invention disclosed herein, different types or modes of processing are executed on different components of the system. For example, 1) the robot 200 may detect that the TV 36 is turned on and determine that it should be turned off, 2) while the hub 110 may assess and process the sensor data from the stationary sensors 120, 122, 124 and the robot sensors to determine whether a zone is occupied, 3) while the remote management server 150 is used to evaluate usage pattern data to generate an energy management strategy. It will be appreciated that, in accordance with embodiments of an invention disclosed herein, or in accordance with an invention disclosed herein, other system architectures may be used that distribute processing response and reporting duties differently than those described above.
According to some embodiments, or according to an invention disclosed herein, the system 100 will deploy the mobile robot 200 to collect environmental data in response to data collected by a stationary sensor 120, 122, 124 or in response to instructions from a user (e.g., via a remote terminal 144). For example, when the system 100 is in a security mode and the hub 110 or remote management server 150 receives data from a stationary sensor 120, 122, 124 indicating the presence of an occupant or opening of a door or window, the system 100 may respond by launching the mobile robot 200 to patrol or investigate a selected zone or zones or the space 20 generally. The robot 200 may send images (e.g., still photos or a live video feed) from the camera 270B or other environmental sensor data to enable the system 100 or user to confirm or better assess the nature of the intrusion or occupancy.
Turning now to the connectivity of household appliances, in accordance with FIGS. 5-13, several embodiments of the present invention include, or an invention disclosed herein, includes, a mobile robot 200 communicating with an end user terminal 142, 144, 300 via a networked hub 110, or via a wireless access point 164.
In some embodiments and according to a first aspect, or according to an invention disclosed herein, a household mobile robot 200 for “coverage” missions (sweeping, vacuuming, mopping, spreading fluid, and/or any combination of these) uses a suitable technique or techniques, in some embodiments, or in an invention disclosed herein, “Simultaneous Localization and Mapping” (SLAM) techniques, to generate a map of the surface being, for example, vacuumed. There are various techniques, and various maps that may be generated. Maps may be topological, Cartesian, polar, representational, probabilistic, or other; and/or may track walls, obstacles, open spaces, fiducials, natural features, “occupancy”, or other map features. In some techniques, many maps, each of some degree of probable correctness, are recorded. In common, however:
1) The surface area in which the robot 200 expects to be able to localize grows over time (i.e., “the map” gets bigger as the robot 200 travels);
2) A relationship between “the map” recorded by the robot 200 and the actual household floorplan (e.g., Zone A, Zone B and Zone C in FIGS. 4, 21, 26, and 27) may be generated or modeled and graphically represented, and at some point the map of navigable area (or a subset of it) is substantially complete;
3) For a coverage robot 200, areas over which the robot 200 has already traveled have been simultaneously covered (usually cleaned or vacuumed), and the covered area may be graphically represented as an irregular area within the complete map;
4) A ratio or other comparison between the covered area and the complete map can be calculated as a percentage or other representation of partial completeness;
5) Specific physical items, such as a hub or gateway device (e.g., hub 110) or a robot dock (dock 140) or wirelessly networked automation device 126, 128, 129, may be located within and represented within the complete map if the robot 200 or another device hosting the complete map receives a localization for such items within the complete map; and
6) Meaningful subdivisions of the complete map may be assigned based on analysis or user input. For example, a leftmost third of the complete map may be designated as corresponding to a kitchen area, a middle section as a living room, and so on. These room identities may be stored as sub-areas or sub-divisions, as transition lines from one subdivision to another, as localized markers within the complete map, or the like.
In the first aspect, the autonomous mobile robot 200 may be provided with sufficient SLAM capability to build a progressively improving map at the same time as it covers (e.g., cleans) within this map, as well as sufficient connectivity to transmit map data (e.g., entire sets of map data, simplified representations of map data, or abstractions of map data). For example, this could include: a microprocessor; a set of sensors collecting and/or calculating range and bearing data from environmental features (including natural landmarks, placed landmarks, and/or walls and obstacles); a map database including at least one progressively improving map; a coverage database including data representing the covered area within the progressively improving map; and a wireless transmitter or transceiver.
In order to reach the public internet with its data or representations and/or abstractions thereof, the microprocessor and/or wireless transmitter or transceiver (including those with their own embedded microprocessors) would communicate using IP (Internet Protocol) and support conventional addressing and packetizing for the public Internet 170.
Any portion of the map database or coverage database may be transmitted to and stored in a location other than the robot 200, e.g., a local hub 110 or gateway within the household, a hub, gateway, server or similar on the Internet, or virtualized instances of the same available on the Internet.
In some embodiments according to the first aspect, or according to an invention disclosed herein, and as illustrated in FIGS. 5 and 6, an application executed by a mobile terminal or device 300 (including but not limited to, for example, a mobile telephone, smart phone or tablet) receives the progressively improving map as well as the covered area within the progressively improving map, compares the two, and displays a representation of the comparison, such as a completion ratio 305 (e.g., percent covered or done by the mobile robot 200). The application instantiates and maintains a user interface element 310 for an end user (e.g., the user of the mobile device 300) to activate to elect to examine the covered area and/or progressively improving map 315 itself. The mobile device 300 may be the local user terminal 142 including a touchscreen HMI, for example.
When the end user activates the user interface element (e.g., the application icon on the touchscreen of the mobile device 300), the application executes a graphical representation of the progressively improving map and the same is displayed, and within this graphical representation, a second graphical representation of the covered area is displayed. It should be noted that the first graphical representation may be replaced with an envelope limiting the extent of the second graphical representation. Optionally, physical devices or locations (such as the location of a robot dock, or the location of an internet gateway) may be localized by the robot 200 and displayed by the application in positions relative to the first graphical representation of the progressively improving map.
According to FIG. 7, in an alternative example, when the user interface element is activated, the application executes a graphical representation of room identity markers 320a, 320b, 320c within the progressively improving map coupled with a completion ratio 325a, 325b, 325c for subdivisions of the complete or progressively improving map 315. That is, each subdivision may have its own completion ratio 325a, 325b, 325c, which may be derived, for example, by comparing the covered area to each subdivision. Optionally, physical devices or locations (such as the location of a robot dock 140, or the location of an internet gateway or hub 110) may be localized by the robot 200 and displayed by the application in positions corresponding to their subdivision.
In accordance with FIGS. 8 and 9, according to a second aspect an autonomous mobile robot 200 is provided with the elements noted above, and also interacting tunable parameters 330a-330d within its cleaning strategy.
For example, a mobile cleaning robot 200 is theoretically able to execute substantially single-pass coverage (i.e., clean each portion of surface area one time and one time only), by following a strategy to cover only area within the progressively improving map 315 that has not already been covered. Perfect single-pass coverage is challenging with an unknown map. Substantial single-pass coverage would be, for example, where the areas that needed to be reached within the progressively improving map were separated by already-covered patches.
This would seem to be ideal, as single-pass coverage is the fastest way to complete the room. However, depending upon the efficacy of a cleaning, spreading, mopping, vacuuming effector, two-pass coverage, or multi-pass coverage, may be the best way to clean. Many stubborn particulates need multiple pass coverage to be adequately cleaned.
Moreover, end users have shown a marked preference for spot cleaning (i.e., cleaning where they can visibly identify a dirt patch themselves, or where dirt is known to be) and also for edge and corner cleaning. Preferences aside, this can also increase overall efficacy, as repeated cleaning of a known dirty area can improve the average level of cleanliness, and corners and edges naturally accumulate dirt with ordinary traffic in any home.
However, these goals (single-pass or “quick” cleaning, multi-pass or “deep” cleaning, spot cleaning, and edge and corner cleaning) are to some extent mutually exclusive. If a mobile cleaning robot 200 repeatedly addresses a dirty spot, it cannot achieve substantially single-pass cleaning (because the dirty spot has been passed over) and will take more time to complete the entire room (absent changes in cleaning power or speed). If a robot 200 follows the perimeter of obstacles and walls twice instead of once, similarly, it takes longer than a single pass.
As such, these goals are correlated with one another. If a robot 200 is commanded to execute the best possible single-pass coverage as an overriding goal, it will never do spot coverage or address edges more than once, and can only begin to perform multiple passes (two, three or more) once the first pass is complete.
Tunable parameters within a cleaning strategy may include time balance (e.g., spend 80 percent of time in single pass mode, entering spot covering mode only 20 percent of opportunities); sensitivity (e.g., enter spot covering mode only when a threshold is crossed, interrupting other modes only upon that threshold event); power output (faster agitation or higher vacuum airflow); and/or forward speed (the traveling speed across a floor).
In one implementation, attention among these goals may be balanced by controlling one or more parameters to lower as one or more than one other parameters increase.
For example, if a slider control is provided in a user interface to represent single pass or quick cleaning goal orientation—for example, 0-100 points of orientation—then a linked, simultaneously and optionally oppositely moving slider may represent multi-pass or deep cleaning orientation. Should the quick cleaning slider 330a be moved to 100 points or percent of attention, such as illustrated in FIG. 8, the robot's 200 cleaning strategy may seek to revisit cleaned areas as little as possible (and the coupled multi-pass slider 330b is automatically coupled to decrease to 0 or very few points). Note that the slider controls in this example reflect a parameter available to the robot's 200 cleaning strategy.
Should the slider 330a be moved to a 50-50 position (with the multi-pass slider coupled to move there as well), the robot's 200 cleaning strategy may seek to prioritize exploring uncertain areas, edges, corners, or map frontiers more, or may concentrate on re-covering proximate areas (e.g., in a different direction).
Another pair of potentially linked sliders may be spot cleaning 330d and edge and corner cleaning 330c. As noted, there are different ways of having two conflicting goals interact. In this case, one way would be to permit the robot 200 to spot clean and/or edge clean opportunistically (upon sensing either of dirt/spot opportunity with optical or piezo sensing, or edge opportunity with proximity sensing), but should both opportunities be detected simultaneously, to permit the higher setting to win more often. This may show a shift in cleaning strategy at 70 percent versus 30 percent “winning” percentage, for example. It should be noted that the sliders or coupled parameters can be set to change interactive principle at along the attention or orientation range. For example, in more skewed or imbalanced settings, e.g., 90 percent versus 10 percent, the robot 200 could begin to ignore opportunities to, for example, spot clean to pursue more opportunities to edge clean.
More than two sliders or tunable parameters may be linked. For example, if all of the quick clean, deep clean, spot clean, and edge clean sliders 330a-330d were linked, moving any one of them may move the others to less emphasis or more emphasis (e.g., in the corresponding direction of slider and attention parameter). As a specific example, if a spot cleaning attention parameter were increased, the robot's 200 reactive threshold to dirt detection could be lowered (or frequency of response, or other parameter that translates into increased orientation). In such a case, the robot 200 may be expected to repeatedly cover already covered areas (lowering the quick clean slider 330a and a corresponding parameter), to spend less time on edges and corners (lowering that slider 330c and corresponding parameter), and to re-cover more areas (increasing the multiple pass slider 330b and corresponding parameter).
The second aspect may include an application executed by a mobile device (including but not limited to a mobile telephone, smart phone or tablet) the receives the current state of the interactive parameters from the robot 200, instantiates user interface controls representative of the relative states (such as slider controls 330a-330d), and displays a representation of the relative states of the parameters using those controls. The application monitors the user interface elements or controls for an end user (e.g., the user of the mobile device 300) to activate to change a parameter, or a percentage emphasis on a parameter, or the like.
When the end user activates the user interface element, the application on the mobile device 300 executes a graphical representation of the progressively changing parameter, and simultaneously with representing the change in one parameter, alters one or more other controls to display a coupled parameter changing simultaneously with the user-controlled activity in the active control.
Turning now to FIGS. 10-12, in another embodiment according to a third aspect, or according to an invention disclosed herein, an autonomous mobile robot 200 is provided with sufficient timer and scheduling capability to self-initiate cleaning on a schedule or be commanded to initiate remotely, as well as sufficient connectivity to communicate schedules and receive commands. In addition, the robot 200 may include connectivity to a local access point or hub 110 which includes, or is connected to, an occupancy sensor. One example of such an Access Point 110 is the NESTTM thermostat, which in addition to controlling household temperatures is connected to the public Internet 170 and local Internet of Things articles via IEEE 802.11 and 802.14 protocols and hardware and may address and exchange messages with remote clients and local articles. In addition, the NEST thermostat includes occupancy sensors (e.g., a passive infrared monitor which can detect passing human body heat and movement, a microphone which can detect ambient noise, and/or an ambient light sensor which can detect variations in light as passers-by obscure it).
In some embodiments, according to the third aspect, or according to an invention disclosed herein, the system of robot 200 and hub 110 (access point acting as a bridge between household Ethernet or 802.11 networks and the robot 200), for example, may include: a microprocessor; a set of sensors collecting and/or human occupancy data from environmental electromagnetic, acoustic, or other sensing; an occupancy database including at least one progressively more accurate profile of household traffic and/or presence map; a scheduling database including data representing the intended missions compatible with the occupancy database; and wireless transmitters or transceivers.
In an example of data collection and communications message flow, the hub 110 may, over the course of a week or longer, survey the local household and identify traffic patterns, with the goal of aligning cleaning schedules of the robot 200 with unoccupied household time(s). The data is analyzed (e.g., anomalies removed, etc.) and stored in an occupancy database.
The occupancy database may be retained by the hub 110, or communicated to the mobile robot 200. In general, it is advantageous to keep small data sets such as this on the mobile robot 200 itself because wireless communications in the home may be interrupted, noisy, or of varying strength throughout a large household.
Any portion of the databases discussed herein may be transmitted to and stored in a location other than the robot 200 (e.g., a local hub 110 or gateway within the household, a hub, gateway, server or similar on the Internet 170, or virtualized instances of the same available on the Internet 170). Most advantageously, the scheduling process works interactively with a charging and/or evacuating dock 140, such that the robot 200 may launch on schedule in a fully charged and/or empty (cleaning bin) state.
In another embodiment, or in an invention disclosed herein, an end user, presented with the occupancy opportunities may schedule activity of the robot in different ways, such as the following:
(1) Requesting the system (hub 110, robot 200, or either) to advantageously schedule household cleaning automatically in the best times available;
(2) Selecting times within the presented occupancy, and/or overriding suggestions from the auto-scheduler;
(3) Adding schedule elements even when the home is occupied, for other needs; or
(4) Tuning room to room coverage, to designate rooms or areas for specific attention on a specific day.
This embodiment, or an invention disclosed herein, may use interactive user interface elements in a mobile device application.
As depicted in FIGS. 10 and 11, when the end user activates the user interface element on a mobile device 300, the application executes a graphical representation of the occupancy database 400 and displays the same. In a modification within this graphical representation 400, a second graphical representation of user selected times 405a-405e within the occupancy database is successively displayed or overlayed.
As depicted in the embodiment of FIG. 12, or in an invention disclosed herein, an end user may wish to be notified when the robot 200, hub 110, or combination of the two intend to launch a cleaning mission, even when the schedule has been approved (or the robot 200 is self-launching according to other criteria). This request notification 410 may be presented to the user on a remote user terminal 144, such as a remote mobile device 300. In some cases, the end user may wish to cancel the launch (for example, if the user is in fact at home but has simply been too quiet for occupancy sensing to operate).
In other embodiments depicted in FIGS. 13 and 14, or in an invention disclosed herein, a user may launch an application via a user interface element on a mobile device 300 to provide calculated information that may be of interest to the user, such as the amount of matter collected by a cleaning robot 200 and/or the location at which the greatest amount of matter was collected. For example, a bin debris sensor maybe used to track the amount of matter entering the robot collection bin. Using a known bin volume, the robot 200 may extrapolate the capacity occupied or remaining in the collection bin based on the amount and/or frequency of matter passing by the debris sensor. Additionally, in embodiments of the robot 200 having mapping capabilities, or in an invention disclosed herein, the robot 200 may track the rate of debris collection and/or the amount of debris collected at various delineated areas or compartments within a floor plan and identify the room containing the largest amount of collected debris.
With reference to the flowchart of FIG. 20, a computer-implemented method according to some embodiments of the present invention, or according to an invention disclosed herein, for receiving user commands for a remote cleaning robot and sending the user commands to the remote cleaning robot (the remote cleaning robot including a drive motor and a cleaning motor) is represented therein. The method includes displaying a user interface including a control area, and within the control area: a user-manipulable launch control group including a plurality of control elements, the launch control group having a deferred launch control state and an immediate launch control state; at least one user-manipulable cleaning strategy control element having a primary cleaning strategy control state and an alternative cleaning strategy control state; and a physical recall control group including a plurality of control elements, the physical recall control group having an immediate recall control state and a remote audible locator control state (Block 30). User input is then received via the user-manipulable control elements (Block 32). Responsive to the user inputs, a real-time robot state reflecting a unique combination of control states is displayed simultaneously within the same control area (Block 34). Concurrently or thereafter, the remote cleaning robot is commanded to actuate the drive motor and cleaning motor to clean a surface based on the received input and unique combination of control states (Block 36).
According to further embodiments, or according to an invention disclosed herein, and with reference to FIGS. 15-18, an application is provided on a mobile device 300 (which may be, for example, the local user terminal 142 having a touchscreen HMI) to provide additional functionality as described below. FIG. 15 shows an exemplary home screen 500 provided by the application to enable control and monitoring of the robot 200. The home screen 500 includes a control area 501 (the active input area of the touchscreen display of the device 300) and therein user manipulable control or interface elements in the form of a cleaning initiator button 512, a scheduling button 514, a cleaning strategy toggle button 516 (which toggles alternatingly between “QUICK” and “STANDARD” (not shown) status indicators when actuated), a dock recall button 520, a robot locator button 522, and a drive button 524. The home screen 500 may further display a robot identification 526 (e.g., a name (“Bruce”) assigned to the robot 200 by the user) as well as one or more operational messages 528 indicating a status of the robot 200 and/or other data.
When activated, the cleaning initiator button 512 will cause the device 300 to command (via wireless signal) the robot 200 to begin a prescribed cleaning protocol.
The cleaning strategy button 516 can be used to select from a plurality of different available cleaning modes, settings or protocols, examples of which are discussed in more detail below. In particular, the cleaning strategy button has a primary cleaning strategy control state (i.e., “Standard clean” or “Deep clean”) and an alternative cleaning strategy control state (i.e., “Quick clean”).
When activated, the scheduling button 514 will initiate a scheduling screen 502 as shown in FIG. 16. The user can use the control elements 502A-F therein to schedule a single cleaning operation/session or a periodic (e.g., weekly) cleaning operation/session by the robot 200. A cleaning mode (e.g., “Standard” or “Quick”) as described below may be selected for each scheduled cleaning session using the control element 502B. A deferred command to begin and execute a configured cleaning operation or session can be initiated by actuating the “Save” button 502F.
The cleaning initiator button 512, the scheduling button 514, and the scheduling control elements 502A-F collectively form a user-manipulative launch control group. This launch control group has an immediate launch state (i.e., when the cleaning initiator button 512 is actuated) and a deferred launch control state (i.e., when the “Save” button 502F is selected).
The dock recall button 520 and the robot locator button 522 collectively form a physical recall control group. The physical recall group has an immediate recall control state (by actuating the dock recall button 520) and a remote audible locator control state (by actuating the robot locator button 522). When activated, the dock recall button 520 will cause the device 300 to command the robot 200 to return to the dock 140.
When activated, the robot locator button 522 will cause the device 300 to command the robot 200 to emit an audible signal (e.g., beeping from an audio transducer or speaker 274B; FIG. 3). The user can use the audible signal to locate the robot 200.
In use, the application on the device 300 receives user input via the above-described user manipulable control elements. Responsive to the user inputs, the application displays simultaneously on the device 300 within the control area 501 a real-time robot state reflecting the unique combination of the control states. The application further commands the robot 200 to actuate the drive system 230 (including a motive drive motor) and the cleaning system 242 (including a cleaning motor) of the robot 200 to clean a surface based on the received input and unique combination of control states.
When actuated, the drive button 524 will initiate a robot motive control screen (not shown) including user manipulable control elements (e.g., a virtual joystick or control pad) that the user can use to remotely control the movement of the robot 200 about the living space.
In some instances, the robot 200 may become immobilized or stuck during a cleaning session. According to some embodiments, or according to an invention disclosed herein, the robot 200 is enabled to recognize its immobilized condition and will send an alert signal to the user via the application on the device 300 (e.g., using SMS or email). The application will display an alert screen 504 as shown in FIG. 17 on the device 300. Additionally or alternatively, the alert screen 504 may be generated in response to the user actuating the cleaning initiator button 512 or the dock recall button 520 when the robot 200 is immobilized or otherwise unable to execute the commanded operation. The alert screen 504 includes one or more control elements manipulable by the user to perform a remedial, subsequent action. In some embodiments, or in an invention disclosed herein, a beacon control element such as a “Beep” button 504A can be actuated to command the robot 200 emit an audible signal from the audio transducer 274B. In some embodiments, or in an invention disclosed herein, an escape maneuver control element 504B can be actuated to command the robot 200 to execute one or more prescribed maneuvers to attempt to disengage or become unstuck.
As discussed above, the application may enable the user to select between two or more cleaning strategies or modes (e.g., using the toggle button 516). According to some embodiments, or according to an invention disclosed herein, the user can (using the toggle button 516) instruct the remote robot 200 to perform either: 1) a lower cumulative energy cleaning strategy (also referred to herein as “quick clean”) with the control element 516 in a first or primary cleaning strategy control state; or a higher cumulative energy cleaning strategy (also referred to herein as “standard” or “deep clean”) with the control element 516 in a second or alternative cleaning strategy control state. As used herein, “cleaning energy” may be deployed in various ways; for example, the robot can either go longer or repeat passes, or can increase motor power, or can otherwise do “more” (standard) or “less” (quick) cleaning. Typically, the quick cleaning options (e.g., as described below) are cumulatively less work. For example, in some embodiments, or in an invention disclosed herein, the robot 200 passes substantially only a single pass over each portion of the covered area in the quick clean strategy or control state, and passes substantially two passes (e.g., the passes crisscross) over each portion of the covered area in the deep clean strategy or control state.
According to some embodiments, or according to an invention disclosed herein, the lower cumulative energy cleaning strategy (“quick clean”) includes one or more of the following:

h. The robot 200 does not detect the density of the dirt lifted from the surface being cleaned.
i. The robot 200 does detect the density of the dirt lifted from the surface being cleaned (e.g., using the dirt sensor 242C) and controls its path, speed or power in view thereof, but the dirt detection threshold required to trigger such modification to its cleaning operation is set at a higher threshold (as compared to the deep cleaning control state).
j. The robot 200 does not evacuate its onboard debris bin 242B during the cleaning session (i.e., except at the end of the cleaning session).
k. The robot 200 spends less time cleaning around time consuming clutter (e.g., table, chairs) (as compared to the deep cleaning control state).
l. The robot 200 cleans high traffic areas first.
m. The robot 200 avoids cleaning under anything invisible to visitors (e.g., under beds, chairs and couches).
u. The robot 200 concentrates its cleaning in a designated area.
According to some embodiments, or according to an invention disclosed herein, the higher cumulative energy cleaning strategy (“standard clean” or “deep clean”) includes one or more of the following:

g. The robot 200 travels at a slower forward speed (as compared to the quick cleaning control state) across the surface combined with a higher vacuum power.
h. The robot 200 does uses more discovery (as compared to the quick cleaning control state; e.g., the robot 200 probes edges and corners more).
i. The robot 200 travels along rows in intersecting directions (e.g., a crisscross pattern).
j. The robot 200 detects the density of the dirt lifted from the surface being cleaned (e.g., using the dirt sensor 242C) and controls its path, speed or power in view thereof.
k. The robot 200 detects the density of the dirt lifted from the surface being cleaned and controls its path, speed or power in view thereof, and the dirt detection threshold required to trigger such modification to its cleaning operation is set at a lower threshold (as compared to the quick cleaning control state).
l. The robot 200 evacuates its onboard debris bin 242A during the cleaning session to increase vacuum power.
m. The robot 200 executes a two or more stage cleaning pattern including a systematic (one or more passes) cleaning pattern and a random and edge diffusion pattern.

The end cleaning mode may include, e.g., perimeter cleaning, random pattern cleaning, or cleaning concentrated on prescribed or detected high dirt areas.

w. The robot 200 spends more time on area rug perimeters and edges (as compared to the quick cleaning control state).
x. The robot 200 seeks to clean under furniture for completeness (e.g., under beds, chairs and couches).
y. The robot 200 detects (e.g., using the dirt sensor 242C) the character or attributes of the dirt lifted from the surface being cleaned and controls its path, speed or power in view thereof. For example, the robot 200 provides less deep cleaning responsive to detection of fuzzy or fluffy dirt, and more deep cleaning responsive to detection of particulate or sandy dirt.
According to some embodiments, or according to an invention disclosed herein, the robot 200, in a given cleaning session, executes a lower cumulative energy cleaning strategy (“quick clean”) in some areas of the coverage area and executes a higher cumulative energy cleaning strategy (“deep clean”) in other areas of the coverage area. According to some embodiments or according to an invention disclosed herein, this multi-mode cleaning strategy includes combinations and permutations of one or more of the following:
a. The robot 200 sets the cleaning strategy for each area or region based on selected or prescribed focus criteria. The focus criteria may include the density or character of dirt collected by the robot 200 in the area.
b. The user, using the application on the device 300, sets the cleaning strategy based on selected or prescribed focus criteria.
c. The user, using the application on the device 300, sets the cleaning strategy for selected subregions or subsections of the area to be cleaned (e.g., different zones such as Zone A, Zone B and Zone C). With reference to FIG. 18, the application may provide an interface screen 506 including a graphical representation or map 506A of the area to be cleaned and cleaning strategy control elements (cleaning mode buttons 506B, 506C). The user can then use the cleaning mode buttons 506B, 506C to select the desired cleaning strategy and then select a region to be cleaned in this manner (e.g., by tracing around a selected area, touching the interior of a designated region 506D-F, or selecting a designated region from a list or the like). The map 506A and designated regions 506D-F may be generated from the map data discussed above and the robot 200 may conduct the cleaning operation with reference to the map and localization with respect thereto.
d. The robot 200 may set the cleaning level based on the floor type it detects (e.g., quick cleaning of hard surface and deep cleaning of carpet).
e. The robot 200 may identify area rugs and execute a deeper cleaning strategy (e.g., more time) on them.
f. The robot 200 may associate bump or other proximity events with detected dirt ingestion events and, in response thereto, execute deeper cleaning. These combined conditions indicate the presence of edges.
In some embodiments, or in an invention disclosed herein, the robot 200 is provided with an onboard, user actuatable cleaning mode selection switch 274C (e.g., a button) that can be used to switch the robot 200 between the quick and deep/standard cleaning modes of operation. The robot 200 may include one or more lights 274A or other indicators to indicate its cleaning mode status (i.e., quick clean or deep clean). The robot 200 may emit an audible signal or signals (using the audio transducer 274B) to indicate its cleaning mode status (e.g., a quick beep for quick clean mode and a long beep for deep clean mode).
According to some embodiments, or according to an invention disclosed herein, the robot 200 or the application on the device 300 is configured to estimate the remaining time required for the robot 200 to complete its cleaning operation and to report the same to the user. In some embodiments, or in an invention disclosed herein, the robot 200 or the application can estimate and report the estimated time required for each cleaning mode in the alternative.
In some embodiments, or in an invention disclosed herein, the user can set (using the application on the device 300, for example) the time available and the area to be cleaned, and the robot 300 or application can determine the appropriate or preferred cleaning mode(s) (quick, deep, or multi-mode) based on these criteria. In some embodiments, or in an invention disclosed herein, the robot 300 or application optimizes the user's original input settings, and the user can then decide whether to adopt the recommendation or proceed with the original settings. In some embodiments, or in an invention disclosed herein, the recommended new settings are indicated by reconfiguring the control elements on the user interface as discussed above, or new settings learned by the mobile robot 200 collecting and processing occupancy schedule.
Some of the determinations discussed above may utilize data derived from sensors that monitor dirt accumulation or extraction from the surface. Examples of such sensors may include instantaneous sensors such as piezoelectric or optical dirt detectors 242C integrated with the robot 200. Also, as discussed above, some determinations may utilize the detected fullness level of the debris bin 242A as detected by the bin level sensor 242B.
The system may further be configured to provide operational messages to the user based on conditions sensed by the robot 200 and/or data collected or derived by the application (e.g., messages 528 and 506C in FIGS. 15 and 17). The operational messages may include robot status messages and/or inquiry messages. For example, the system may display on the device 300 “You should do a deep clean soon; quick shows that the amount of dirt is higher than average. Would you like to schedule a deep clean? When? You are not normally at home Tuesdays at 11—how about tomorrow at 11?”
In some embodiments, or in an invention disclosed herein, the application on the device 300 enables the user to input designated high traffic areas for corresponding cleaning by the robot 200. In some embodiments, or in an invention disclosed herein, the robot 200 is configured to discover or detect and identify high traffic areas automatically and programmatically.
In some embodiments, or in an invention disclosed herein, the application on the device 300 enables the user to select a cleaning pattern or patterns (e.g., spirals, back and forth, crosswise, or scrubbing) the user believes or has determined are preferable in some regard (e.g., better, quicker, or deeper).
The remote user terminals as disclosed herein (e.g., terminals 142 and 300) may be communication terminals configured to communicate over a wireless interface, and may be referred to as “wireless communication terminals” or “wireless terminals.” Examples of wireless terminals include, but are not limited to, a cellular telephone, personal data assistant (PDA), pager, and/or a computer that is configured to communicate data over a wireless communication interface that can include a cellular telephone interface, a Bluetooth interface, a wireless local area network interface (e.g., 802.11), another RF communication interface, and/or an optical/infra-red communication interface. In some embodiments, or in an invention disclosed herein, the remote user terminals 142, 300 are mobile terminals that are portable. In some embodiments, or in an invention disclosed herein, the remote user terminals 142, 300 are handheld mobile terminals, meaning that the outer dimensions of the mobile terminal are adapted and suitable for use by a typical operator using one hand. According to some embodiments, or according to an invention disclosed herein, the total volume of the handheld mobile terminal is less than about 200 cc and, according to some embodiments, or according to an invention disclosed herein, the total volume of the handheld mobile terminal is less than about 100 cc.
FIG. 19 is a schematic illustration of an exemplary user terminal that may be used as the user terminal 142 or 300 as discussed herein. The terminal 300 includes a human-machine interface (HMI) 370, a communication module, and a circuit or data processing system including a processor 380 and memory 382. The circuits and/or data processing systems may be incorporated in a digital signal processor. The processor 380 communicates with the HMI 370 and memory 382 via an address/data bus 380A. The processor 380 can be any commercially available or custom microprocessor. The memory 382 is representative of the overall hierarchy of memory devices containing the software and data used to implement the functionality of the data processing system. The memory 382 can include, but is not limited to, the following types of devices: cache, ROM, PROM, EPROM, EEPROM, flash memory, SRAM, and DRAM.
