Rubik’s Cube Robotic Solver
I was amazed to see that someone had built a robot that solves the 3×3x3 Rubik’s Cube.

The solution involves a Lego® Mindstorms base, 3 arms for grasping and turning the cube faces, a Logitech Quick Cam to scan the cube faces and recognize the colors, and some VB code to control the arms & interface to the camera. The robot usually finds a solution in 30 moves or less.
