Hand Andersson’s Tilted Twister is a LEGO robot that can solve a scrambled Rubik’s Cube in about 6 minutes. I’ve seen LEGO cube solvers before, but there’s something a bit different about this one, which you can see in the video below:

If you didn’t catch the difference, this robot is solving the puzzle on its own with no attached PC!

A light sensor is used to scan all six faces of the cube. The robot then calculates a solution for the cube, before executing an average of 60 turns to complete the puzzle.

The robot is built from the parts available in a retail NXT kit—no extra or custom pieces are necessary. You can build one yourself using the LEGO Digital Designer CAD file and NXC source code that are available from Hans’ site.
