In response to the lack of research on a universal architecture for multi robot collaboration systems suitable for FPGA platforms in existing literature, this paper introduces a multi robot collaboration system based on FPGA. The system constructs a communication network between robots based on UART communication protocol, and uses a designed information transmission mechanism to enable FPGA to receive data from all robots and control them. At the same time, to cope with abnormal situations, an alarm mechanism and remote control mode are also designed for the system. After the actual construction of a multi robot collaboration system and the verification of its functions one by one, the feasibility of the design concept of the multi robot collaboration system proposed in this paper has been confirmed.
