Shai Revzen, an assistant professor of electrical engineering and computer science plus biology at the University of Michigan, is studying cockroaches with a goal toward building better robots. As a graduate student at the University of California, Berkeley, he designed an experimental setup that records high-speed imagery of the insects scurrying across a small bridge. The roaches run onto a platform that is then released from an elastic spring, sending it swinging sideways with great force. It's equivalent to Revzen running and being tackled by a sumo wrestler, according to a U of Michigan news release. Watch the roaches run below.
