Very beautiful robotics and open source project coming from France:
Poppy is an Open-source humanoid platform based on robust, flexible, easy-to-use hardware and software.
Designed by the Flowers Lab at Inria Bordeaux and Ensta ParisTech (France), its development aims at providing an affordable and hackable humanoid robot for science, education, art and geeks.
Poppy was initially made for our research project about understanding biped locomotion, and full-body physical and social interaction in robots and humans.
