At the conference, IROS was presented "robot on the ball"

Probably, this robot can become quite famous, since its design is quite original. Swedish developer Peter Fankhauser (Péter Fankhauser) and called his brainchild - Rezero ballbot. The ball is used as the basis for the movement of the robot, and the device is perfectly balanced, never falling.

The project Rezero ballbot began to be implemented last year, then ETHZ students assembled their devices literally from wire and scrap metal. Now the robot looks more sophisticated than its first robots, and it’s already assembled not from wire. Rezero ballbot is able to move in all directions, and quite quickly. No walking manipulators, no wheels or tracks - just a ball.

Of course, not only Peter, but the whole team is working on the project, but this person is the initiator and ideological inspirer. Yes, in order to prevent the robot from falling, a complex system of gyros is used. Thanks to her, the robot never really falls. But riding with a very decent speed.
