A1 Open-Source Bionic Leg | Prof. Elliott Rouse and Prof. Levi Hargrove

52m | Jan 24, 2021

Interview with the senior authors of the article “Design and clinical implementation of an open-source bionic leg” (Azocar et al., Nat Biomed Eng, 2020), Prof. Elliott Rouse, Ph.D., at the University of Michigan, and Prof. Levi Hargrove, Ph.D., at the Sherly Ryan AbilityLab and Northwestern University. We discuss their Open-Source Leg project in the context of the state-of-the-art in prosthetic legs, promising research directions, and how to identify “not so good” research or development ideas.

Interview by Max Ortiz Catalan, Ph.D., Assoc. Professor on Bionics and Director of the Center for Bionics and Pain Research (Social media: FB, TW, IG, and LI).
