Abstract:
A control system for a mobile robot (10) is provided to effectively cover a given area by operating in a plurality of modes, including an obstacle following mode (51) and a random bounce mode (48). In other embodiments, spot coverage, such as spiraling (45), or other modes are also used to increase effectiveness. In addition, a behavior based architecture is used to implement the control system, and various escape behaviors are used to ensure full coverage.

PROBLEM TO BE SOLVED: To provide a mobile robot cleaner allowed to operate in a plurality of modes for effective cleaning.SOLUTION: A mobile robot cleaner includes a driving mechanism 21 having drive wheels 20 for forward movement and turning of a robot body, a non-contact following sensor 16 for detecting an obstacle near a prescribed side, a cleaning head 30 for collecting dust, and a controller 30 for controlling the driving mechanism based on signals from the following sensor. The controller (1) drives the driving mechanism so that the robot body moves away from an obstacle, and when the state of the following sensor changes, (2) drives the driving mechanism so that the robot body comes near the obstacle, and when the state of the following sensor changes again, brings the processing back to (1). The controller also drives the driving mechanism so that the robot body repeats (1) and (2) in a wall following mode. The following sensor is provided with an infrared light generator and an infrared light receiver directed ahead of the drive wheels in the travelling direction.
