Structure Design and Movement Simulation Research of Bionic Artificial Leg
Bionic artificial leg is used to simulate the disabled health leg and provided ideal following gait for intelligent prosthesis test, so it raises a high demand about humanoid character and intelligent control. Referring to the parameters of human leg and the movement mechanism, the bionic artificial leg was designed and analyzed in this paper. In order to improve the humanoid character and stability of bionic artificial leg, the knee joint was designed as a four bar linkage which was driven by two pneumatic artificial muscles and the lengths of bars were optimized by the genetic algorithm. Then, this paper analyzed the bionic artificial leg movement and established the system model. Finally, the stability and humanoid character of system is verified by the MATLAB movement simulation.
