I knew this,  but it helps to have proof.

How cool is this?

Rubik's cube solver done in Lego.

CubeSolver

This robot solves the 3x3x3 Rubik's Cube®.

I started to think about this problem in about August of 2000. In Jan 2001 fellow Mindstorms forums user 'agiecco' announced his intention to work on a robotic solution and, simultaneously, I saw that Rubik's Cubes were on sale at www.target.com. So I bought a couple of cubes and started getting down to business...

I produced a 'late beta' version in mid-April 2001 that was a little clunky. The final version (presented here) is smooth and fairly reliable.

Amazing.
