The weeding robot is mainly controlled by STM32C8T6 micro-controller chip and the end of the weeding actuator to control the machine. This paper mainly introduces the overall design of the external structure, hardware and software of the weeding robot. The movement mode of the weeding robot adopts wheel structure and uses high-power driving circuit to drive. A six degree of freedom manipulator is used at the end of weeding, and the length of the manipulator is adjusted according to the requirements of the degree of freedom. In the control system, STM32CT6 micro-control chip is used as the control part of the whole weeding robot, the motor adopts the high-power motor with the ultimate torque of 91kg, and the steering gear on the mechanical arm adopts JX digital steering gear. Through software programming and later debugging, the robot's straight, left turn, right turn, weeding mode action is realized.
