Abstract
In this paper, an assistive device for a knee joint to help a disabled person to stand up by supporting power is presented. The device is designed and controlled by using damping characteristics of the MR (Magneto-Rheological) damper. The MR damper helps the person to sit slowly and safely. A DC motor supports muscle power in the case of standing motion. Thus the device helps the disabled person to sit down and stand up. Through the experiments, it is feasible that an assistive device can help the disabled person to standup according to the foot pressure change.
