Design and Kinematics Analysis of a Lower Limb Exoskeleton Robot

Abstract

The lower limb exoskeleton robot is a new technique of rehabilitation training for lower limb dysfunction, which is paid more and more attention by people. Because the lower limb exoskeleton robot is relatively heavy all over the world, this article designs a new lower limb exoskeleton robot whose hip joint is driven by motor and other joints are unpowered. It effectively reduces the lower limb exoskeleton robot’s weight. The kinematics equation of exoskeleton robot is established by D-H coordinate system, and the correctness of kinematics equation is verified with combining simulation by MATLAB and SolidWorks software. The end coordinate data calculated by kinematics equation is used as a contrast to test, and a good walking effect is achieved.
