Abstract: With the gradual maturity of robot technology, the application of robots in agricultural production has become more and more widespread. However, most of the robot communication systems use wired communication methods. The data transmission lacks real-time performance and is not conducive to the long-distance transmission of data information. Based on this, this paper designs and researches a picking robot communication system based on an infinite sensor network, analyzes the functions and characteristics of a variety of wireless communication technologies, completes the design of the overall scheme of the picking robot communication system, and designs the hardware circuits, Coordinator selection and motor drive circuit design, the design of communication protocols for control signals and sensor signals during the communication process is completed, and the data transmission test of the communication system is completed. The experiments show that the picking robot communication system based on wireless sensor network has good stability, high data transmission accuracy, fast transmission speed, and can guarantee the security and continuity of agricultural machine information storage.
