Wobbly - The Slope Walking Automaton

See a video of Wobbly walking here: http://youtu.be/DtdJB49f4Yk

Wobbly is a toy robot who can walk down slopes. He is purely mechanical and made up of 3D printed parts. (He does not need a wind-up motor, nor batteries. He runs on gravity.)

You will need to provide a coin to put in his jetpack to act as a weight, and you will need to glue his head onto his body. Besides that, everything else is 3D printed. [In the video, I blu-tacked a coin onto his back. You can now use the Rocket Pack accessory instead of doing that!]

Check out the Instructions tab for details on how to put him together and for tips on getting him walking. (He can be a bit shy about walking when you first assemble him, so please check out the tips. I'm sure you'll get him walking in no time. He just needs to get to know you first. ;D )

Wobbly was inspired by an awesome wooden, ramp walking automaton created by Roberto Lou Ma. You can see Roberto's automata, and his instructions for making a wooden one here. As I don't have much wood working skills, I thought I'd try to create a fully, 3D printable version. Wobbly is the result.

I hope you have fun with Wobbly and please post a comment or pictures if you make him! I would love to see Wobbly's brothers/sisters.
