Univ of Tokyo H6 Humanoid
Ray-traced (POVRay v3.1)
2000 

This robot was previously part of my research on humanoid robots.  I derived the model directly from the CAD data, converted to POV format, and adjusted the pose and material properties.  This image was just a test rendering using 3 slightly-colored spotlights with POV media effects to highlight the Univ. of Tokyo H6 Humanoid.
