Let's Make Robots!

making wheels out of plastic bottles

This is an old idea, finally I have the time to show it to the world.
The are bottle shapes that perfectly fit together, you will see how easy it is to create a wheel from two plastic bootles, the video speaks for itself.

Check this project to see how I attached the wheels to a continuos rotation servo motor.

I like your idea too,great ignitiative.  I would also think of using plastic bottles on water as floaters and with a bit of modifications they might rotate too :P

Sorry for double post.

Nice. And light weight too, if one should have focus on that :)
