In areas where it snows a lot in winter, the elderly people cannot go out for exercise, so that they have a loss of motor ability and high risk of falling. The falling is one of the causes of bedridden state. In order to solve this issue, we develop a system which can facilitate indoor exercises for the elderly people. In this system, we use compact-size robots and pedaling electrical generator for the exercise motivation. In this research, we have performed a verification test in a care facility in order to determine whether this exercise system is practical or not.
