Golf-swing robot emulating a human motion

The performance of golf clubs and balls is generally evaluated using a golf-swing robot that conventionally have two or three joints with completely interrelated motion. This interrelation allows the user of this robot to specify only the initial posture and swing velocity of the robot and thus, the swing motion of this type of robot cannot be subtly adjusted to the specific characteristics of individual golf clubs. Consequently, golf-swing robots cannot accurately emulate professional golfers and this causes serious problems for the evaluation of the performance of golf clubs. In the paper, a golf-swing robot that can adjust its motion to both, a specified value of swing velocity and the specific characteristics of individual golf clubs is investigated analytically.
