The Cubli: a cube that can jump up, balance, and 'walk' In a fascinating exploration of robotics, the video titled "The Cubli: a cube that can jump up, balance, and 'walk'" showcases an innovative 15x15x15 cm cube named Cubli, which employs cutting-edge technology to perform remarkable stunts. The core technology involves reaction wheels mounted on three faces of the cube, which allow it to execute complex maneuvers such as jumping, balancing, and even 'walking' by leveraging gravitational forces.

How It Works​

The Cubli relies on an intricate system comprised of brushless DC motors, inertial sensors, and an embedded processor, which work together to maintain balance. The use of a nonlinear controller is crucial, as it enables the cube to stabilize itself on its corner and employ angular momentum effectively. It incorporates Hall sensors for angular velocity data, which is vital for calculating the motion and balance of the cube. The process can be broken down into a few key maneuvers:

1. Jumping: The Cubli can jump from a resting position to achieve a balanced stance. This is accomplished by rapidly rotating the momentum wheels to build up angular momentum and then transferring this energy to the cube's body.
2. Balancing: Using its sensors and control algorithms, the cube can balance on its edges and corners, responding dynamically to disturbances.
3. Controlled Falling: The motors can adjust the fall direction, giving the cube the ability to 'walk' by transitioning between these states.

   Applications and Future Potential​

   While the Cubli serves as an impressive demonstration of robotics, its potential applications are far-reaching. Researchers envision using decentralized balancing systems like Cubli for planetary exploration missions where traditional locomotion methods are not feasible. There's also interest in applying these mechanics to self-assembling robotic systems, which could revolutionize how robots are constructed and deployed. In conclusion, the Cubli isn't just a mechanical marvel; it opens doors to future technologies that could transform robotic exploration and automation. Whether it's for fun or functional design, the ingenuity behind the Cubli demonstrates the incredible potential of robotics in our ever-evolving tech landscape.
