FOBO is the fourth prototype from Project Biped.  It is a self-contained, statically balanced bipedal robot. It has 8 DOF (degrees of freedom) and can walk around its environment and avoid obstacles using an ultrasonic range sensor.  All of the designs, instructions, source code, and parts lists are provided for free.  FOBO was designed to be easily made by anyone with a low cost 3D printer and an interest in learning about robotics.  Check out the FAQ if you have any questions.
