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’.

  1. This is the future! Cubes can now balance themselves!

  2. Oh goodie. Hubble's reaction wheel assemblies in a toy. Does it have a gyroscope to determine its position?

  3. I'm attending at this exact univeristy ETH Zurich in a year.. wish me luck, I have high chances tho!

  4. that cube looks like a tv… can we see the remote?

  5. A well designed gyroscope in a cube that’s not new, and we don’t call it “jumping cube”.

  6. So THAT'S how the Fortnite cube worked…

  7. now, all you have to do is make a shell out of plastic, color it purple, and now you have Kevin the cube!

  8. so this is how the fortnite cube worked

  9. Give it an Arnaldo Pomodoro's style (Google it's spheres and cubes they are awesome) and than bring it to an alien convention. You will be the star of the show

  10. the can made beer bottle holder 😀

  11. Top 10 unsolved mysteries
    Number 10: why is this in my recommended

  12. Why are people building this instead of curing cancer

  13. Needs to lower the volume.. too loud

  14. And the point of this thing is..?

  15. Were can I buy one or a diy set that’s awesome

  16. Put it in a box and then give me one.

  17. It builds another cubli and you think it’s building a buddy so, the cubli won’t be lonely but in reality it’s building an army to make the world into a cube…. It’s 4 a.m and I should go to sleep

  18. after some polishing, we can use this mechanism for advance active shock absorber for cars. yes its achievable ., imagine when cars fell into some small ditch or cutter in a road then the vehicle's body will obviously lean to affected tyre.. ok now, just think what if we put something similar to this cube to opposite side of the affected tyre we can literally reduce a huge amount of shock

  19. in my recommended 5 years later but not complaining

  20. Put it on a turn table to see what the torque is doing. Will it also spin?
    What would it do in zero G?

  21. Attach a missile launcher and some machine guns and send it of to war! U S A, U S A!

  22. It sounds like an old Windows XP computers fans when starting up
