摘要： A data carrier system allows data to be transmitted and received. The data is transmitted using weak radio waves of suitable frequencies, such as frequencies in a high frequency band (HF) or a very high frequency band (VHF). The transmitters and receivers need not physically contact each other, be located in any particular position, or be oriented in any particular direction. The data carrier system does not suffer deficiencies in electric power supply, and therefore there exists no need to exchange batteries. Individual transmitters and receivers are positively discriminated one from another. The receivers are in the form of a plurality of tags. The transmitters are in the form of a plurality of reader-writers. Both are controlled by microcomputers, and each tag is equipped with a secondary battery as the power source.

摘要： 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.
