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 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.

Two of my favorite memories from growing up in the late 70's--Rubik's cubes and Legos (although they have evolved a little since then!)--brought together. Very nice.

Ooooh! I really need to see a vid of this thing in action. Nice work!

Truly amazing! (note: image referenced on MakeZine

I'm a french teenager and I would like to know if you have a video of the robot in action. I have worked with lego mindstorms and I participed to the first lego league championship in Atlanta.
It's a very nice work!
