Automated Artificial Leg Mechanism for Above-Knee Amputees

Abstract

The expensive price of a prosthetic leg for above-knee amputees caused some of them to be unable to afford it. This is especially relevant for people with low income that live from paycheck to paycheck. With the addition of the aforementioned disability, they would be unable to earn income. Hence, this project aims to provide a cheap solution for above-knee amputees to restore their mobility. The solution that is explored is the use of an echo-control scheme that mimics the bending and flexion of the sound leg and transmits it to the prosthetic leg to mimic. Through the test that was done, the prosthetic leg was able to perform its function albeit its swing velocity is 10 times slower than that of a sound leg. Further enhancement in the future can consider implementing a system that allows the prosthetic leg to work independently from LabVIEW if needed as well as increasing the speed of the prosthetic leg during the gait cycle.Reduce the cost of prosthetic legs and make them more widely available to people especially those with low income.
