TENTH INTERNATIONAL CONGRESS ON SOUND AND VIBRATION , ICSV 10 DESIGN AND ANALYSIS OF A PARALLEL MECHANISM FOR THE GOLF INDUSTRY
Previous work done in the study of golf club dynamics professes dissatisfaction with robotic testing used to evaluate and compare golf equipment. The main complaint is that the club dynamics measured during a robot swing do not correlate with the same data in a human swing. This paper presents the design and analysis of an alternative to the current robotic testing systems. The viability of a parallel kinematic (two-arm) concept as a robotic testing machine for golf clubs and balls is demonstrated. Human biometric data was used as the basis for determining link geometry as well as motion planning for the swing. Models, simulations, and correlations with human test data were used for validating the design. A demonstration prototype was built to show the interactions and motions of the various components.
Motion planning for a new golf swing robot
A new golf swing robot to simulate the human skill of motion control in a golf swing has been developed by authors. It consists of one actuated joint and one passive joint with mechanical stopper. Optimal motion planning of the robot to satisfy the boundary conditions and non-holonomic constraint introduced by the stopper under different cost functions is discussed. A general method for motion planning of such types of system is described and the results of motion planning for the golf swing robot are shown.
