Design and Fabrication of an Automated Prosthetic Leg Testing Setup

About this project

This project involves the development of a testing setup for an automated prosthetic leg, featuring a 350 mm mild steel shaft, two plates supporting a 4 kg wood piece load, and a 3 Nm torque stepper motor controlled by an Arduino Uno and DM556 driver. The setup simulates ±90-degree rotations over 10 seconds to mimic gait cycles, with a focus on moment analysis and stability under ISO 10328:2016 standards. Future improvements include integrating EMG signals from a human residual limb to replicate natural gait and implementing adaptive control for enhanced prosthetic testing. The system is powered by a regulated power supply and validated through MATLAB and ANSYS simulations.
