DESIGN OF A KNEE EXOSKELETON ASSISTING DURING WALKING, SIT-TO-STAND, AND STAIR ASCENDING

In this study, we present a knee exoskeleton that assists weight acceptance in walking, sit-to-stand and stair ascending. Working principle of the device is inspired from bio-mechanical data natural human gait, sit to stance ascent motions. First, analyze gait identify behavior joint. Then build model for stand motion with an elastic element. After that, analyzed similar manner. Then, define appropriate elements, their coefficients motor requirements if necessary, these specific tasks. Finally, CAD proposed exoskeleton.
