Robert Gregg & Toby Elery — Robotic Prosthesis Built with ISS Motors

September 23, 2020 @ 8:17 am

In this episode:

 

We meet Drs. Robert Gregg and Toby Elery, who are part of a team that has designed an improved robotic prosthesis, produced using a motor originally designed for use on the International Space Station (ISS).

 

Dr. Gregg is an Associate Professor of Electrical and Computer Engineering and Robotics at the University of Michigan in Ann Arbor. He earned a Bachelor of Science in electrical engineering and computer sciences from the University of California, Berkeley, and then subsequent masters and doctoral degrees in electrical and computer engineering from the University of Illinois at Urbana-Champaign. He joined the University of Michigan as an Associate Professor of Electrical and Computer Engineering, and the Robotics Institute, in fall 2019.

 

Dr. Elery is a mechanical engineer and researcher based in Dallas, Texas, who earned his PhD in Mechanical Engineering from the University of Texas at Dallas in the spring of 2020. Up until April of this year, and for nearly six years prior, he was a PhD Graduate Research Assistant at the university. He's worked on a host of robotics projects, has served as a mentor for undergraduate projects, and has also disseminated his research in the field via several publications and presentations.

 

In this conversation, our guests discuss how the idea came about to produce a better robotic prosthesis, why a motor produced for the ISS was chosen for their design, how their prosthesis lessens the burden on wearers, which wearers will benefit from it the most, the testing that has been performed so far, and also explain how the force from the residual limb actually charges the battery while the prosthesis is in use.

 

Describing how an ISS motor was chosen for their design, Elery explains that it was among those with “the highest torque density, which means it can produce a lot of force in a very small package, which was really useful for our application. So, we were able to get a whole lot of torque — a whole lot of force out of it, in a really small volume.”

Aaron Shepard – NASA Robotics Intern & Founder of Cogito

September 2, 2020 @ 8:34 am

In this episode:

 

We meet Aaron Shepard, an In Space Assembly Robotics Intern at NASA Langley, and a Robotics Research Assistant at Clemson University College of Engineering and Science. Aaron also works at R&D Engineering Co-Op, Itron, Inc., and is the Founder/CEO of Cogito, a company dedicated to inspiring young people through STEM outreach.

 

He is affiliated with the Mars Generation, an international nonprofit organization that works to excite people of all ages about science, technology, engineering, mathematics, and human space exploration, and is currently a member of the organization's Student Space Ambassador Leadership Board, where he serves as chair of the outreach committee. He works as a tutor and mentor for the PEER & WISE program at Clemson, which helps to give underrepresented students studying STEM subjects the resources and tools they need to follow their dreams of STEM and space, and he has also given a TEDx talk entitled Make America Space Again.

 

In this conversation Aaron talks about what inspired him to switch from his initial career path of medicine to robotics, gives details on how he got into his internship at NASA, shares his thoughts on the future of robots in space exploration, touches on his company Cogito, describes his favorite robot project that he’s currently working on, and explains how he thinks international cooperation will help achieve our goals in space.

 

In describing how robots will eventually build human habitats on other planets, Aaron says, “I’d say we’re within a 20-year range of having fully autonomous robot construction crew in space ... I think that’s possible.”

Note: This episode refers to the successful July 30, 2020 launch of the Perseverance Mars Rover and Ingenuity helicopter in future tense because the podcast was recorded on July 23, 2020.
