| Abstract | ||||
| In this paper, a controlled semi-active ankle prosthetic using parallel and series spring systems was developed. The proposed 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 performance of the proposed model and a non-amputee ankle is compared. The results show that 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 which indicates that the proposed model has high efficiency. The angle and torque of the controlled semi-active ankle prosthetic are strikingly like those of non-amputee ankles. | ||||
