Here's a robot video that I found interesting:
Jin Sato, the founder of JS-Robotics, developed the OpenFace robot avatar project and plans to make the STL files available so that others can use it as a base to give their robot creations more personality and realism. With the exception of a few screws and other parts, the design is completely 3D printable. The sample demonstrated at the IREX robot exhibition in Tokyo was printed on a Solidoodle printer and features 6 degrees of freedom.
