In Japan, the population of person requiring support is increasing. Local government has encouraged gymnastics of care prevention. But, its participation rate is low. On the other hand, tele-robotics is the system to convert exercise to some works if user's operational input is considered as exercise. Therefore, we develop input device which operation will be exercise for the preventive care and combine it with tele-robot. Then tele-robotics contributes to daily life and hobby of the elderly. We expect this increse their motivation to exercise. In this study, we developed the light gun type input device for manipulator for care prevention, which operation will be exercise.
