In some special picking jobs, such as complex mountains, cliffs and other high-risk areas, the study of a two-way communication robot, on the one hand can return complex operating information, on the other hand can be issued through the control center Control instructions to guide the robot in the complex environment to complete the picking operation, has important practical significance. Therefore, based on the WIFI wireless local area network, an interactive terminal picking robot with real-time digital image transmission is proposed. The image is acquired with an HD CMOS camera. The MCU and processor are used to process the image and control signals. The WIFI model is used to complete the image And control signal transmission. In order to verify the feasibility of the scheme, the communication between the monitoring terminal and the robot receiving terminal was tested respectively. The test results show that: Picking robot using WIFI wireless communication, the communication speed and communication distance compared to other wireless communication methods have obvious advantages, can effectively complete the digital image transmission. The bit error rate of two-way communication between the receiving terminal and the picking terminal is statistically analyzed. The statistical results show that the communication precision is high, which can meet the design requirements of the picking operation in complex environment.
