Materials for Biomimetic Robots – Rob Shepherd

Deep Future

I've gotten to spend a little bit of time with Rob Shepherd over the years. He's working on soft robotics and all the different kinds of materials advancements that could really help us make robots that are more naturally integrated into the world.

Things like polymer colloidal suspensions as inks for 3d printers so they can fabricate microfluidic devices, synthesizing single micron to millimeter scale parts in glass and silicon and all kinds of other stuff, like tiny gears. Imagine if you were trying to make a micro machinery like Swiss watches, but smaller. That's the kind of stuff that he worked on in the past and researched, developing pneumatic actuators, different kinds of elastomers and things that could maybe give us a real kind of muscles for robots.

Also developing the kinds of walking and undulating movements that you would want robots to do once they got beyond just being these kind of rigid jerky things that we have now. This also gets really interesting when you're trying to make fingers for robots, which I'm personally obsessed with. I think it is a kingpin that's going to enable robots to start going to all the places they haven't been able to. We've seen some real progress on that lately.

Rob is a great guy, super humble, willing to share everything he knows, which is a lot. Rob is an associate professor at the Sibley School of Mechanical and Aerospace Engineering at Cornell university.

We recorded this in Ojai, California in a In-n-out Burger, on a Friday night, when it was full of teenagers... So this is it also an exercise in using AI for noise canceling, post-facto.

I know it won't be the cleanest recording you've ever heard, but I think it will be interesting to know that we ran the audio through a tool called AUDO, and AUDO is one of many. I don't have anything to do with them. I've talked to the founders few times. I think it's cool. There's probably other ones, I don't know what the best ones are, but I've been using AUDO, and it's able to do this remarkable job cutting out, like a hundred noisy teenagers, while Rob and I are just sitting there eating burgers, talking about robots.

So hopefully you'll learn something from that as well...

About Rob Shepherd

Rob Shepherd received his B.S. (2002) and Ph.D. (2010) in Material Science at the University of Illinois where his research focused on developing polymeric and colloidal suspensions as 'inks' for 3D printers.

He also fabricated microfluidic devices to synthesize single micron to millimeter scale parts. Concurrently to performing this research, he received his M.B.A. (2009) at U of I and started a company, worked with several other startups, and gained significant experience with the details of market research, financials, accounting issues, and legal aspects of entrepreneurship.

In 2010, he continued his education as a post-doctoral fellow at Harvard University in George Whitesides's research group in the Department of Chemistry and Chemical Biology. In this group, he developed pneumatic actuators in soft elastomers that took the form of a machine capable of moving in multiple gaits: walking and undulating. These actuators have also been used for low-cost manipulators, and in concert with a microfluidic system for biomimetic camouflage & display.
