If you thought the Tinkertoy Tic-Tac-Toe computer was impressive, you haven't seen anything yet!

Daniele Benedettelli has taken some LEGO Mindstorm sets, introduced them to the Rubik's Cube, added her experience with artificial intelligence.

The result was the LEGO Rubik Utopy! The unit, also known as the LRU, can look at a mixed cube and then proceed to solve it in the fewest number of moves possible!

The LRU page details all the steps that were taken in the project. The starting point was J. P. Brown's Rubik's Cube solver, and Daniele's own cube-solving software. The story is one of simplification, testing, problem-solving and design.

Two of the steps are demonstrated with videos, with the final results seen here. Some criticize it as slow, but the LRU is nonetheless impressive!
