Prodos is a self contained bipedal robot that was designed to demonstrate how to coordinate simple limb chain actuation using a microcontroller. It has 8 DOF (degrees of freedom) and can perform a simple walking action. The servos used were selected for economy and aren't powerful enough to bear the robot's own weight, so Prodos must be externally supported while it is actuating. Prodos 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.
