I am remixing these two Biped robots to create a little C-3PO for my daughter. She is 4 and a huge fan of the Droid from Star Wars and has a small obsession with robots (we are working on three at the moment).

Using TinkerCad I took the head from Tito (http://www.thingiverse.com/thing:1378605) and added a mouth instead of the three LED lights. I also made the head about 6mm taller to accommodate a servo shield for the Arduino. I also modified the Chassis from the ZOWI to better fit the components I intend to eventually include.

I am planning on soldering a custom servo shield using this board as the base: https://www.adafruit.com/product/2077

Right now however I am using a servo shield from eBAY: http://www.ebay.com/itm/282029679227

Legs and Feet were printed as is from the Original ZOWI bot: http://www.thingiverse.com/thing:747010

Thanks to the Kevin for his original BoB biped robot http://www.thingiverse.com/thing:43708 which inspired so many derivatives such as this one.

Added (10/23/16): App inventor project for android control with HC-06 bluetooth module. Left the sound fx button without sound (I used sound clips from the golden robot himself).
Also added the Zowi library I cobbled together from a few different Github versions. Also uploaded the sketch i am using for the Robot.

flip the head upside down for no support printing. I used support and a raft for the legs. everything else was printed with ABS right on the base.
