In order to solve the problem of automatic rust removal and protection of power drawing cables, a new type of rust removal robot is proposed. The design of main mechanisms such as walking, pressing, adjustment, rust removal and control system are completed, then the overall system of the rust removal robot is constructed. The 3D solid model of the robot is created based on SolidWorks, and a virtual prototype of the robot is established using ADAMS software, and its kinematics and dynamics characteristics are simulated and analyzed. Finally, the physical prototype of the rust removal robot has been manufactured, and experiment in reality working condition has been carried out. Simulation and experiments results verify the feasibility of the theory and design of rust removal robot for power drawing cable.
