Robotic Prosthesis

The robotic leg prosthesis is a two-joint device, with powered knee and ankle joints. Most prosthetic legs are passive, using no power, and are optimized for performing one task- walking on level surfaces. Young wanted to see what would happen if a device was designed to be able to adapt to a user’s needs, whether that’s climbing stairs, walking on a ramp, or moving around on the flat ground. A major part of that is trying to understand when someone wants to transition between these different tasks and to be able to give the appropriate assistance at the right time. The goal is for it to be natural, automatic, and intuitive to the user with no need to hit buttons or switches during transitions. Instead, the objective is to develop an intent recognition system that employs a variety of machine learning and artificial intelligence techniques to interpret sensor information and anticipate what the user is going to do next.

These engineers approach robotics from different angles, but they share the same goal - they want to develop wearable robotic devices that can help people maintain or increase their mobility. 

Aaron Young and Greg Sawicki's labs in Georgia Tech’s George W. Woodruff School of Mechanical Engineering are laying the groundwork for a range of devices that could help children, stroke patients, the elderly, and amputees gain more independence and move with greater comfort and ease.
