Motion Control of Golf Swing Robot Based on Target Dynamics

A new golf swing robot performing high-speed golf swings has been developed by the authors. This paper deals with the motion planning problem of the golf swing. A target dynamics based control scheme is proposed. This control scheme maps the robot to a harmonic oscillator (target dynamical system). Based on the target system, energy control is adopted to realize a specified hitting speed at a specified impact position in the swing. After the swing passed through the impact position, PD control and PD plus gravity, joint torque and coupling torque compensation control are adopted to smoothly slow down and stop the swing at a specified finish position. Simulation and experimental results show the effect of the proposed method
