Notes:
The servos and 9v battery are pressure fitted into body. Head has a large cavity for LED, along with a thin outer shell, this gives the head a nice glow effect. Buck converter must be adjusted to give between 5-6 volts (mine is set closer to 6). Traction for feet is necessary so that it moves forward, you can roughen the feet (sand them), or apply a thin layer of hot glue. There will likely be some trial and error with finding the right amount of traction, but otherwise an easy build.
