A cube is not the object we think of when we talk about motion. However, Cubli is exactly that - a cube that moves on its own alongside a host of other surprising talents. It was designed at the Institute for Dynamical Systems and Control, ETH Zurich in Switzerland.
Cubs measures approx 15 centimeters to each side and walks so that prumbling around its edges. Even more presentable is the fact that it can balance itself at any point and even jumps. It relies on rotating wheel system inside. Three main wheels, each rotating about one of the three main axes, rotate faster or slower so that enough momentum is maintained to balance the cube at the desired point. With fast by stopping one of the spinning wheels, the cube stops and turns over, allowing it to "walk".
Researchers with of the institute the system is said to be similar to that used for stabilization of satellites in space. Some other groups are even developing the use of such a system for development robots, which would be used in the exploration of alien planets.
