Abstract
Operation analysis is applied for various field, but usually people can only get visual or analytical data from motion analyzer, but cannot get physical feelings directly in their bodies. Li some fields such as sports and rehabilitation, it is more efficient to feel motion than to see the motion image nor read numerical data in order to acquire skills. The aim of our research is to develop a device to teach people directly the desired action by the force produced by Control Moment Gyroscope (CMG). hi particular we focus on the swing motion training of golf, baseball or tennis play. This paper introduces the developed CMG prototype and its application in the pendulum movement control with experimental results.
