Abstract: This article presents a multi-robot communication system of autonomous robots. In the system, the wireless local area network of IEEE802. 11b standard is employed as a foundation, and the C/S network communication mode is adopted. And a full-duplex communication protocol, which is fit for the communication of autonomous robots, is designed. The multi-robot communication through the PC simulation with the socket network programming is realized. The data transmission through the system is reliable, and real-time is high. The system can meet the need of autonomous robots communication.
