Arduped 2

Arduped 2 is a tweaked version of David Ultis's Arduped Biped Robot (http://www.thingiverse.com/thing:19594) that includes source code by Gabriel Ro-Bot-X and Kai Neugebauer to make it work. I redesigned the build platform and head sensor and tweaked the feet, but I left the original legs alone because they worked just fine. The [OpenSCAD](http://www.openscad.org/) source files for these changes can be found in the zip file called "OpenScad Files with Utils Folder.zip".

* 1x Ultrasonic sensor HC-SR04
* A small on/off rocker switch (should be easy to find on Ebay)
* 2 x M3 x 25mm screws to mount the servo for the head. M2 screws are actually preferable here as you will have to drill out the servo mount a bit to use M3 screws.
* 4 x M3 x 12mm screws to mount t
