BloodKeith, a robot hobbyist from China, has designed and built himself some pretty sweet robotic hands. The hands themselves have 7cm long fingers, with 5cm for the thumbs, and the fingers are simultaneously controlled by a single servo. The videos on his blog show the hands grasping various objects and opening/closing at different speeds. The first two videos that demonstrate speed are particularly creepy and, at 3am, concerned me greatly. The hands also remind me of the Terminator hand in Terminator 2, but made out of Lego.
