Abstract：In view of the disadvantages of traditional teaching robots such as poor recon- figurability, insufficient comprehensive application of the system and simple human-computer interaction function, this paper designs and develops a reconfigurable dynamic and static gesture interactive teaching robot based on field programmable gate array (FPGA). The robot uses Spartan6 of Xilinx as the controller, uses OV5640 camera to recognize and transmit the gesture image information, uses I2C bus to communicate with FPGA, and uses WiFi module to transmit data, so as to control the robot with corresponding gesture instructions. It realizes many functions, such as human-computer gesture interaction, mechanical arm grasping, automatic tracking, ultrasonic obstacle avoidance, motion obstacle removal, voice broadcasting and so on. At the same time, the recognition accuracy of the gesture control robot is 95.1%, and the real-time recognition response time is less than 0.5s. A FPGA-based reconfigurable teaching robot controlled by dynamic and static gestures designed in this paper can be used in the teaching of research courses such as FPGA system design, and has promotion value.
