Abstract
An object of the present invention is to provide a sensor system which can effect local communications suitable for exchanging information to avoid collisions between mobile robots. The sensor system also prevents collisions between the mobile robots and obstacles. The system is well-suited for a multi-robot environment where multiple mobile robots operate. The system includes infrared signal transmitters installed in each of the multiple mobile robots for sending transmission data via infrared signals. The system further includes infrared signal receivers installed in each of the multiple mobile robots for receiving the transmission data sent by the infrared signal transmitters. Each mobile robot includes a control unit. The control unit prepares transmission information which includes mobile robot identification information unique to the mobile robot. The transmission information is included in the transmission data sent from the infrared signal transmitter. The control unit also extracts transmission information which is received by the infrared signal receiver.
