A more comfortable robotic prosthetic leg

July 15, 2020

A new robotic prosthetic leg prototype offers a more natural gait while also being quieter and more energy efficient than other designs. 

The key is the use of new small and powerful motors, originally designed for a robotic arm on the International Space Station. The streamlined design offers a free-swinging knee and regenerative braking, which charges the battery with energy captured when the foot hits the ground. This feature enables the leg to more than double a typical prosthetic user’s walking needs with one charge per day.

Open-source bionic leg: First-of-its-kind platform aims to rapidly advance prosthetics

June 5, 2019

A new open-source, artificially intelligent prosthetic leg designed by researchers at the University of Michigan and Shirley Ryan AbilityLab is now available to the scientific community.

The leg’s free-to-copy design and programming are intended to improve the quality of life of patients and accelerate scientific advances by offering a unified platform to fragmented research efforts across the field of bionics.

A Shoutout to Two Michigan PhDs in Robotics

February 6, 2017

The research of Mechanical Engineering and Robotics alum Dr. Alireza Ramezani is featured on the February cover of Science Robotics. Dr. Ramezani defended his dissertation, “Feedback Control Design for MARLO, a 3D-Bipedal Robot,” in 2013. 

The U-M Mathematics Department has awarded Hamed Razavi with the 2016 Sumner B. Myers Prize, which honors the best PhD thesis in mathematics. No award is made unless a thesis is judged to be truly distinguished:

Hamed Razavi, “Symmetry Method for Limit Cycle Walking of Legged Robots”, co-advised by Tony Bloch (Math) and Jessy Grizzle (EECS).
