Research on magnetic soft robots attracts NSF fellowship

Introduction

Opposites attract, and with funding from the National Science Foundation, Nick Bira, a doctoral student in robotics, is incorporating magnets (traditionally hard and rigid) with robots that are soft and pliable.

He was awarded a prestigious Graduate Research Fellowship to support this work. The fellowship recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based graduate degrees at accredited United States institutions. Past fellows include numerous Nobel Prize winners, U.S. Secretary of Energy, Steven Chu, Google founder, Sergey Brin, and Freakonomics co-author, Steven Levitt.

Bira is examining ways to utilize magnetically responsive elastomers 鈥 rubber-like materials with embedded magnetic particles 鈥 in soft robotic applications.

鈥淵ou can make many interesting mechanisms and develop potential strategies for robots that use this material in creative ways,鈥 said Bira. 鈥淚 want to explore ways to use the material properties of the robot itself to perform different tasks that have not been done before.鈥

According to Bira, little research has been done with soft robotics and magnetism. 鈥淲e鈥檙e talking about rubber, and magnets are typically hard, rigid, concrete things that might be powered by electronics,鈥 he said. 鈥淢y work is trying to bridge that gap.鈥 He thinks he can do that by making the soft materials magnetic.

One of the motivations for his work is the potential for soft robotics to assist in biomedical engineering. 鈥淲hen it comes to assistive devices or prosthetics, there seems to be a natural fit for things that are soft, like humans,鈥 he said. 鈥淚 think my work will be able to assist toward that goal.鈥

The NSF fellowship will provide him full funding for the remainder of his doctoral program. 鈥淭his will free up my time that would otherwise go to working as a teaching assistant or working on a professor鈥檚 grant funds.鈥

This is not the first time that Bira has benefited from NSF funding, nor his first time studying robotics at 精东影视 State. While he was completing his undergraduate degree at the University of Missouri, he spent a summer participating in the NSF-funded Research Experience for Undergraduates in 精东影视 State鈥檚 robotics program and worked with Yi臒it Meng眉莽, assistant professor of robotics, to develop electrically-controllable, hydraulic valves for use in soft robotic applications. 鈥淭hat was a great experience,鈥 he said, 鈥渁nd it really drove me to come here for graduate school.鈥

Bira鈥檚 graduate advisor is Joe Davidson, assistant professor of robotics.
