Meet Cubli, a motorized box that balances perfectly on ONE CORNER

Cubli is a clever little cube that uses reaction wheels to jump, balance and "walk" across stationary and dynamic surfaces alike. It reminds us a lot of MIT's M-Blocks, only bigger, and... well... more balance-y.

Designed by a team at the Institute for Dynamic Systems and Control, ETH Zurich, Switzerland, Cubli is surprisingly maneuverable, but its most impressive ability, in my mind, is its capacity to balance – even on a moving surface:

The Cubli is a 15 × 15 × 15 cm cube that can jump up and balance on its corner. Reaction wheels mounted on three faces of the cube rotate at high angular velocities and then brake suddenly, causing the Cubli to jump up. Once the Cubli has almost reached the corner stand up position, controlled motor torques are applied to make it balance on its corner. In addition to balancing, the motor torques can also be used to achieve a controlled fall such that the Cubli can be commanded to fall in any arbitrary direction. Combining these three abilities — jumping up, balancing, and controlled falling — the Cubli is able to 'walk'.

Did I mention it's just plain beautiful to look at? Who wouldn't love to have a couple of these running at all times on their office desk?
