Abstract
In this study, we develop a power assist suit adapted to bi-articular muscles model. Before now we have already developed the leg mechanism of power assist suit adapted to bi-articular muscles model using parallel links. The leg mechanism of power assist suit adapted to bi-articular muscles model has high torque and safety from a series of experimental results. Therefore, we improve Power Assist Suit based on conventional leg mechanism confirmed the good efficiency. Furthermore the new model is able to hold 10kgf weight as a result of mechanical improvement. In addition, we consider distinction method by Neural network with electromyography control.
