Control moment gyroscope for swing motion control

The analysis of movements has been applied to various fields. However, they are typically only in the form of visual or analytical data from a motion analyzer. Users are unable to feel these types of analysis directly on their bodies. In some fields, such as sports and rehabilitation, it is more efficient to feel a motion than to see the image or numerical data in order to acquire skills. Therefore we propose a device to teach users a desired motion directly using force produced by a Control Moment Gyroscope (CMG). In particular, we focus on a swing motion in golf, baseball, or tennis. This paper introduces the developed CMG prototype and its validation in the control of pendulum movement.
