My wife linked me to TiltedTwister.com, because she knew I would watch the video end to end, jaw agape.  Hans Andersson has used only the pieces in the Lego Mindstorms NXT retail kit to build a robot that can solve the Rubik’s Cube puzzle in about 6 minutes.

The TT uses it’s one little eye to scan the entire cube first, then plans its moves accordingly. Even more amazing is that the robot only has a single motor that will only turn the bottom row. Hans, your brain is huge.
