Abstract
We have developed a new mobility aid "Tread Walk". It helps older persons to perform "extending mobility activities," "maintaining body function" and "natural walking appearance". The mobility aid consists of two main components; a six-wheel driving part and an operating part including two belts treadmill. This permits the user to walk naturally while a servo motor amplifies normal walking speed on the treadmill system. Here, we propose natural operation from gait movement. The new concept is to measure acceleration/decceleration force of one's legs by separated belt and to use the input for change direction.
