One of the grand challenges in the proliferation of powered robotic limbs is thought to be the ease of controlling these complex systems by their human users and the versatility of their control algorithms across a variety of users and activity types. The Open Source Leg was born in response to the need for a portable, powered, product-like leg to serve as a common development platform. The growing community of researchers and developers, now with support from Humotech, which provides fully-assembled legs as well as assembly packages, are pursuing a wide variety of novel approaches to prosthetic leg control.

Press Release: University of Michigan, Humotech partner to bring open-source bionic leg to research labs
The open-source, artificially intelligent prosthetic leg designed by researchers at the University of Michigan will be brought to the research market by Humotech, a Pittsburgh-based assistive technology company.
The goal of the collaboration is to speed the development of control software for robotic prosthetic legs, which have the potential to provide the power and natural gait of a human leg to prosthetic users.
