The Cubli: a cube that can jump up, balance, and 'walk'






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'.

Foucault Pendulum:





In 1851, physicist Léon Foucault demonstrated the rotation of the Earth by his experiment conducted in the Panthéon, by constructing a 67 meter Foucault pendulum beneath the central dome. The original iron sphere from the pendulum was returned to the Panthéon in 1946 from the Conservatoire National des Arts et Métiers.
