Badminton is one of the famous sports and enjoyed by people of all ages and both sexes. Recently some sports maker try to produce high quality product because of player and progress of player's level. Firstly, practical badminton machine is developed with a target to meet with player's practice and is produced experimentally with the rotation arm system launch structure from human arm imitation in this study. Then, high speed photography is taken to understand the launch behavior of practical badminton machine and to evaluate launch velocity and launch precision of this machine. It follows that launch behavior is changed by spring grow, gripper angle and gripper shape. Finally, launch behavior is simulated and evaluated. The simulation result is in almost agreement with the one from the practical machine on the launch behavior.
