Research Description
This work develops a controlled semi-active ankle prosthetic using parallel and series spring systems. The model of the controlled semi-active prosthetic ankle is composed of parallel springs, leaf series springs, and a cam. for reduction torque and power consumption as much as feasible, the parallel and series springs must function as a nonlinear system. As a result, the cam system is used, which has parallel and series springs. The controlled semi-active ankle prosthetic with parallel and leaf series spring was modelled using the CAD-CAM software. The controlled semi-active ankle prosthetic behaves similarly to a non-amputee ankle. The power consumption of the motor has been reduced by 51.67 percent. The angle and torque of the controlled semi-active ankle prosthetic are strikingly like those of non-amputee ankles.
