Aiming at the problem of a single function and a low degree of automation of live operating robot in the target substation, a multi-function operation tool control system for substation equipment charged maintenance and maintenance operation robot is designed. The system consists of three main parts: controller, sensor and actuator. In order to meet the control requirements of different operating tools, the system adopts different control platforms and different control strategies, and designed the human-computer interface. The system can enable the robot to perform multi-function operations, realize the automatic operation of the robot, and enable the operator to master the robot's state better.
