Péter Fankhauser: Meet Rezero, the dancing ballbot

The video introduces Rezero, a Ballbot developed by students at ETH-Zurich. Rezero balances on a single ball, making it inherently unstable but highly dynamic. It uses sensors to measure its pitch angle and motors to maintain balance. The video demonstrates Rezero's capabilities, including maintaining position, passive movement, and following or orbiting a person. Potential applications include use in exhibitions, parks, and hospitals. The technology is experimental but offers practical and aesthetic value.
