RepWalker Mutant Ra04

The RepWalker is a Shellmo module. Shellmo is an open source robot project with it's homepage at shellmo.org and a forum at shellmo.net. A Shellmo should have legs, a heart and eyes - you can find the eyes for my Mutant RA04 here http://www.thingiverse.com/thing:328939
I have designed this RepWalker Mutant RA04 based on Sho's original RepWalker. While he wanted a light weight robot to print on Shapeways (each sq cm is money) I redesigned all parts for my RepRap printer. This means material doesn't matter, no fine details and the focus on "easy to print" and robust to play with.
I also looked for easy to source muscles and designed RepWalker Mutant RA04 to be powered by hacked standard servos with a 40 x 20 mm (about 5 US$ at HK - I used this one with two ball bearings plus one brass bushing in the gear train for added smoothness and precision http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=44049). You can find some info on how to hack such servos in the net or on my web page (such continuouse rotating servos can also be sourced already hacked...)
The RepWalker is a platform for an Arduino based robot. You can pimp it with bumper switches and all kind of sensors. You can design your own building platform on top of the #18-collarbones or just place the Arduino on the #20-brain-fastener. Be creative and enjoy this little robot platform.
We will publish more add-on's during the next time. So please have a look at shellmo.net to see what is going on and to share your creations!
