Research Abstract

We tried to develop the assisting leg motion system, for example, standing motion, walking motion, without the power supply which enable users to control the system considering their abilities.
We measured the leg motion, and using these results, we designed the planar six-link mechanism in order to make the mechanism trace the trajectory of the human leg joint.
In case of the device for assisting standing movement, the springs are used the power sources, and the users operate with a control lever themselves. In case of the device for assisting walking movement with the saddle to support the body weight, the artificial walking motion is used as the input motion to drive the device. In the case of the wearing device for assisting walking movement, the swing motion of arm as walking is used to drive the device.
