Rezero Robot Reviews

Rezero Robot Reviews

Peter Fankhauser from the ETHZ in Zurich tells us about the Rezero Ballbot, a balancing robot that speeds around on a sphere.

Péter Fankhauser is the leader of the Rezero ballbot project. The Rezero project was one of last year’s “Focus Projects” during which Bachelor students in Mechanical Engineering at ETHZ have the opportunity to develop a product from scratch. The project was supervised by Prof. Siegwart from the Autonomous Systems Laboratory. Rezero brought together eight future mechanical engineers, two electrical engineers studying at the ZHAW as well as Industrial Designers from ZHdk.


The interdisciplinary team developed the ballbot, a robot that balances and drives around on a ball. Using a single ball instead of wheels allows the robot to move spontaneously in any direction, fit into tight spaces, and achieve high speeds. The robot was often seen zipping through the hallways at IROS earlier this month.
