Description
So I recently saw a blog post on hypocycloid gears on the Reprap Blog ( fabricationsofthemind.com/2010/07/09/extruder-design-1-printable-1001-hypocycloidal-gearbox/ ) .
Some really good info on them can be found here:
zincland.com/hypocycloid/
Also do a search on youtube for hypocycloid reducer. Lots of vids.
They seem to be perfect for a robot arm joint. I want to make a robot arm. I started to put one together in OpenSCAD. I have way more than I'm uploading here, but this is just the arm joint. The outside layers are fixed and the inside four layers rotate as the gears turn. I wanted to cut this using ponoko bamboo, but there is no way to go from OpenSCAD to ponoko bamboo (that I know of). I don't have a makerbot yet.
Hopefully someone can pick this up and run with it. The file needs to be edited quite a bit to print it out on a Reprap or something. Drop me a message if you want to print this out and I can help you understand the file.

This looks fairly interesting, but some documentation regarding assembly, ideally listing the needed parts, would be helpful. I also really appreciate it when folks upload STLs so that you can look at them in Thingiview, even if those STLs are not at all intended to be used and merely for illustration. You mentioned this was part of a larger project; did you get any farther on it?
