Powered control and performance testing of bionic leg / 中国组织工程研究

ABSTRACT

The prosthesis is forced by pneumatic artificial muscle, which can swing like human legs by inputting signals such as square waves and trigonal waves.Its swing performance is tested under such triggerings in order to find out a best motivating curve rendering the prosthesis performance almost the same as what human legs do. Compared with the normal human pace graph, the curve matches very well in the ascending edge but quite a discrepancy in the end of descending edge. According analyzing the reasons of the discrepancies, we could know how to ameliorate the design of the next generation of the bionic legs.
