Abstract:
A self-propelled harmful agent detector for traversing spaces in buildings comprising:a harmful agent sensor for sensing chemical and/or biological agents injurious to human health, the harmful agent sensor having a data output; a transceiver coupled to the harmful agent sensor data output for transmitting data from the self-propelled harmful agent detector and receiving instructions from a central control station; a power source; a motor having a moving output and being supplied with power from the power source; and a traction device coupled to the motor moving output for moving the self-propelled harmful agent detector; and a controller for controlling the motor such that the self-propelled harmful agent detector is moved along one or more predefined paths, the controller being coupled to the transceiver to receive instructions related to controlling the motor and the traction device, wherein the controller is adapted to modify a predefined path in response to instructions received by the transceiver.
