ABSTRACT:
Generally, the invention can be used to strike an object with an implement. Two applications for which the invention is particularly useful are hitting a golf ball with a golf club, and hitting a baseball or softball with a baseball bat. The invention can be used to, for instance, test an implement (e.g., golf club or baseball bat) used to strike an object (e.g., golf ball or baseball), either to verify acceptable performance of the implement, or to provide information regarding the performance of the implement to assist in the further design of the implement. The invention can also be used to test the object (e.g., golf ball or baseball) being struck. Additionally, when the invention is used to hit a baseball or softball, the invention can be used to hit balls to enable one or more players to engage in fielding practice. An apparatus of the invention includes a frame, an arm rotatably mounted to the frame, and a drive mechanism adapted to rotate the arm, such that when the arm is rotated, an implement held by the arm strikes an object. The apparatus of the invention further includes one or more of several novel features that enable the apparatus to swing the arm in a desired fashion.
