A clever combination of motorized reaction wheels, sensors, processors and software allow the 15cm^3 Cubli to balance on its corner or edge, and to stabilize itself in the face of disturbances, or spin on its corner. It can also ramp up its wheel speed, brake them suddenly and use the angular momentum to leap up onto its corner from a flat rest, then fall onto a proscribed side, and leap up -- walking, in other words.
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'.

I’m about to switch off my email until September 5 and drive to Black Rock City for 10 days of incinerating the dude.
As Oracle desperately tries to reanimate its wretched, failed attempt to destroy everything Sun Microsystems stood for and end computer science as we know it, there’s never been a better time to rock one of these “You Wouldn’t Reimplement an API” tees, which were an underground hit during the earlier trial.
Kyohazard’s Lament Configuration is a terrific piece of fan-art for those of us who loved the Hellraiser movies (the good ones, at least).
