Abstract
Thousands of patients suffer from knee instability as a result of a variety of conditions. Wearable robots have therefore attracted attention as an alternative for restoring lost function and extending the physical function. These robots, however, also often exert resistance force on the wearer due to a lack of consideration of knee rotational movement. In this study, we have therefore focused on knee rotational movement and have found that it is possible to steer the knee joint in the appropriate direction by using two actuators. We measured the amount of misalignment caused by the interaction of the wearer with the device using a motion-capture system. As a result, we have confirmed the validity of a developed robot.
