Swiss researchers have created Cubli, a cube that can jump up, balance on its corner, and walk about.
Cubli is a small robotic cube with 15cm sides, incorporating flywheels rotating around 3 perpendicular axes. By spinning a flywheel at high speed and suddenly braking Cubli can jump up, and by tightly controlling the speed of the three wheels can balance on a side or on a corner.
The creators from the Swiss Federal Institute of Technology in Zürich envision possible uses in planetary exploration and self-assembling robots. I’m not too sure about practical uses, but it certainly looks cool!
