Abstract
Recently, many types assist devices are developed. However, because a lot of developed assist devices are using the actuators and control systems, and these devices rise the cost and increase in size. Therefore, it is difficult for a general person to use it. Then, in this paper the assist device of hip joint is developed and produced. It is enabled to wear it readily by using the link mechanics like a supporter. Moreover, the device is used in the hip joint and the angular displacement is measured and the angular velocity and the angular acceleration are calculated and the performance is evaluated when walking.
