Abstract
Many people of all ages have sustained cervical cord injury in traffic accidents, sport accidents, and so on. Specifically, there are a lot of people which suffered from C5 level cervical cord injury. They have lost the ability of lower limb and also can't exert extension force in elbow joint in daily living. Thus, many motions become difficult to perform in daily living. In the future, wearable assist motion robots are expected to be incorporated into daily living. In order to be wearable, the assist robot must not limit the user's range of motion while being carried or used, and must be suitable for a wide range of situations. In this study, we develop extension force support system which bases on operator's volition under the effect of external force by using wearable assist motion robot for upper limb. The effectiveness of the developed system is demonstrated experimentally.
