Angular momentum 3d stabilizer



Some time ago I wanted to build a cube that could seemingly defy the law of physics and balance on its edges or corners. To achieve this aim I decided to use spinning weights which would create a large angular momentum. So if the angular momentum gets bigger than the gravitational force, the cube would remain in its position even if it was balancing on its corners.


So there had to be three angular momentum axis: X Y Z


I used three 600 6V DC motors:

 



















piece of wood with metal weights



electric motor


















I attatched the motors to square plates which would form a cube later.

This is the first result: I added some protection to enclose the spinning discs.

The video shows a rotating disc: The laser was used for measruring the disc's speed
I also had to calibrate the disc very accuratly in order to prevent vibrations.

Tada!! 
Turn on the cube and you will need some force to move it!
You can take it and place it on its corner and it won't fall but remain in its position as long as the discs are spinning!
Not really useful but ... :)

  10. No use for it? Hell, just showing it to people and watching them go "wow" isn't a good enough use? lol

    Following for moar!

  13. I thought of a use for it, with a little adaptation it would be a cool gyroscopic stabiliser for a video camera

  17. Great gyroscope : ) Technical universities from my city always show this on science fairs. Nice.
