How Fast Can a Machine Solve a Rubik's Cube?
How fast can a machine solve a Rubik's cube? The answer is 0.38 seconds. Blink and you'll miss it. But they will show it again in slow motion.
What kind of machine does this? It's called the Rubik's Contraption, and it was built by Ben Katz and Jared Di Carlo. They say it would go much faster if it weren't for the time spent actually moving the mechanical Rubik's cube. They could push it faster but the toy tends to fall apart under the pressure. Ben tells about about the machine and its specs here, and Jared gives an overview of the software here. I don't understand much of it at all, but I am impressed. -via Digg
