Abstract:
A robot learning system for trajectory learning of a robot (RB) having a robot arm between a base and a tool center point (TCP). A user interface allows the user to control the robot arm in order to follow a desired trajectory during a real-time. A probe sensor (PS) is mounted on the TCP during the learning session. The probe sensor (PS) measures a distance parameter (Z) indicative of distance from the TCP and a surface forming the trajectory to be followed, and an orientation parameter (X, Y) indicative of orientation of the TCP and the surface forming the trajectory to be followed. These distance and orientation data are provided as a feedback to the controller of the robot (CTL) during the real-time learning session, thereby allowing the robot controller software to assist the user in following a desired trajectory in a continuous manner. Especially, the probe sensor (PS) may have a displaceable tip (TP) to follow a surface and having a neutral or center position, and where the robot controller software controls the robot movements to seek the neutral or center position irrespective of the user's control inputs. Data (DT) is logged during the learning session, so as to allow later control of the robot (RB) in response to the data (DT) logged during the learning session.

Claim (Index 1):
A robot learning system for trajectory learning of an associated robot comprising a robot arm between a base and a tool center point, by demonstration from a user, the system comprising:\n a user interface configured for connection to a controller of the robot, so as to allow the user to control the robot arm in order to follow a desired trajectory during a real-time learning session, wherein the user interface comprises at least a first control element for being operated by the user, and being configured to control position in space of the tool center point of the robot, a probe sensor configured to be mounted on the tool center point during the real-time learning session, wherein the probe sensor is configured to measure a distance parameter indicative of distance from the tool center point and a surface forming the trajectory to be followed and an orientation parameter indicative of orientation of the tool center point and the surface forming the trajectory to be followed, and wherein the probe sensor (PS) is configured to continuously generate one or more signals corresponding to said distance and orientation parameters, and wherein said one or more signals is provided as a feedback to the controller of the robot during the real-time learning session, and a processor configured to log data in response to the user's operation of the at least first control element during the real-time learning session, or continuously logging data at a predetermined sample rate, so as to allow later control of the robot in response to the data logged during the learning session.
