Motion control of golf swing robot based on dynamically coupled driving

A new golf swing robot to simulate human's motion has been developed by authors. The basic design concept of the robot is to realize high speed swing motion while by a smart structure, just like human. By the concept, the robot consists of a shoulder joint with powerful direct-drive motor and a wrist joint with small direct-drive motor. And for the reason, swing motion at high speed should be realized by a skill of motion control, so called dynamically-coupled driving, to compensate the lack of driving capability in the wrist joint. This paper deals with the motion control of the robot. First, a new model of golf swing robot with considering the flexibility of golf club is established and all parameters are identified by experiments. According to the new model, trajectories for different criteria an; generated and implemented to the robot. Experimental results show high accuracy of the motion control
