This is the Spinnybot. When you wind it up and put it on a carpet it spins round... And round... And round...
That is all it does. Now let's get on to the instructions...
Step 1: A Note
This uses 3 K'nex spring (windup) motors. I don't know if it works with less or a different type of motor, and if it does, you will have to modify the motor section. Now on with the building!
Step 2: The Disc
This is the disc. This is easy to build. Enough said.
Step 3: The Gearbox/Motor Housing
This is where the motors are housed. All pics are different views.
Step 4: The Axle
This is the axle. To be honest, it doesn't deserve its own step.
Step 5: Assembly
This is the bit where it all fits together. Follow the image notes.
Step 6: You're Done!
Wind it up, put it down, and watch it spinnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn!
