Abstract:

Based on the detection and maintenance work in the nuclear fusion reactor vessel as an example, a snake-like remote control manipulator with multi-joint series structure was presented, which adopted a composite control plan based on track push pull and adjustment with suspending arms. Aiming at the demand of the manipulator to carry out the whole vessel operation, the trajectory of the manipulator was simulated and analyzed. A motion control algorithm including path planning and trajectory control was designed, and a multi-axis coordination control system was established. The motion of the manipulator was tested inside the geometric simulation vessel environment, and the control accuracy of the joint rotation angle was evaluated. The gravity compensation module of the manipulator system was constructed, and the terminal positioning accuracy of the manipulator system was evaluated by the simulation of the flexible model. The test results verified the effectiveness of the motion control system.

Key words: nuclear fusion reactor vessel, snake-like manipulator, path planning, multi-axis coordinate control, control precision
