Design and research of eight-link rehabilitation training robot based on single degree of freedomitle.

In order to reduce the treatment cost required for the recovery of patients with nerve injury, a rehabilitation training robot based on single-degree-of-freedom eight-link leg mechanism is proposed. The robot imitates human gait by repeatedly and naturally moving the legs. Clinical cases show that this training can help patients to carry out targeted exercises, such as leg activity exercises, improving balance, physical training and so on. The motion cycle of the mechanism is matched with the generalized gait cycle in clinic. Then, based on the support phase and swing phase of the gait cycle, the mechanism is optimized by adjusting the link length through kinematic analysis. The theoretical calculation and virtual simulation are carried out by using SOLIDWORKS, MATLAB and ADAMS software, and the feasibility of the mechanism is verified. The conclusion of theory and simulation is that the design of this single-degree-of-freedom eight-link leg walking mechanism can provide a basis for low-cost rehabilitation training based on patients with spinal injury.
