Cubli is a cube that can balance on a corner or edge or walk around by flipping over its edge or can be ordered to have a smooth fall.
The cube, six inches in length, was developed by researchers at ETH Zurich's Institute for Dynamic Systems and Control and can maintain its balance if pushed over. The cube relies on three spinning motors to get it going that will spin faster, slower or stop to help maintain its balance or continue the flipping motion.
