Meet Rezero, the dancing ballbot

Engineering student Péter Fankhauser demonstrates Rezero, a robot that balances on a ball. Designed and built by students, Rezero is the first ballbot made to move quickly and gracefully — and even dance. (Could the Star Wars sphere droid be real? Watch this and judge.)

Péter Fankhauser is the leader of a team of students working on Rezero, a robot that balances on a single sphere.
