Abstract
The assistance of an assist walker is effective for movement of elderly people who have anxiety concerning walking. A motor mechanism for assisting acceleration / deceleration has been developed in recent years. However, incorporating a drive mechanism in a swinging caster makes the structure excessively complicated. For this reason, ordinary wheels with fixed axles are generally used for assist. On the other hand, if such a normal wheel is used for a walker, it will impair its turning ability in a narrow place. In order to realize the intermediate characteristic of these two problems, we trialed a walker incorporating motor power to the omni wheel.
