De Cubli kubus balanceert zichzelf zonder hulp van buitenaf

Het 'Institute for Dynamic Systems and Control' in Zurich heeft een kubus gemaakt die op 1 hoek kan staan zonder dat daar extra hulp of steun voor nodig is. De 'Cubli' meet 15x15x15 cm en kan zichzelf op zijn kant of zelfs op 1 hoek zetten en zo blijven staan. Straf!

"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'."
