We have worked with Össur, one of the leading manufacturers in prosthesis technology, to test our control algorithms on their commercial hardware. The video above shows our data-driven variable impedance controller deployed on the Össur Power Knee. We’re working on quantifying the clinical benefits of the Power Knee and investigating how these benfits depend on the control policy used.

The prevailing paradigm in lower-limb robotic prosthesis control is to use hand-designed controllers with heuristically tuned behaviors. While these approaches can be very effective, they are labor-intensive in both the design of the behaviors and in individualizing them to each individual at the point-of-care. In this work, we instead developed a data-driven control architecture that allowed the prosthesis to work over continuums of tasks without requiring manual tuning.

The Open-Source Leg project aims to accelerate research in the field of lower-limb robotic prostheses by providing a common research platform to the field. Senthur Ayyappan, a rockstar mechanical designer and software engineer, currently maintains and leads the project along with PI Elliott Rouse at the University of Michigan. Full CAD design files, software libraries, and other resources are available to the public to use free of charge. See www.opensourceleg.org for more information.
