About this 3D model

I built this small prototype to test several concepts: the tracks made from O-rings, a simple robotic claw, and wireless communications with Arduino. This thing uses: My robotic claw http://www.thingiverse.com/thing:18339 Some parts from my previous designs http://www.thingiverse.com/thing:13298 Obijuan's Skymega board http://www.thingiverse.com/thing:14197 and battery pack http://www.thingiverse.com/thing:5079 See it move at: http://youtu.be/SQqVQEaMtno UPDATE 3/8/2012: The part "front.stl" did not print correctly due to some dangling polygons. I have now replaced it with the correct file! UPDATE 3/13/2012: Uploaded a folder with the scad files. Not very tidy though...
