I saw this guy on a TV program about 2 years ago. He had just built a really clunky robot from Lego Mindstorms and a laptop, to solve the cube. He used algorithms that would minimise the number of moves, not for speed as such, but because every time the Lego jaws moved, there was a chance they'd fall apart, or set the cube slightly off-twist, and fewer moves meant more likely to get to the end. On the show back then, it failed after just a few moves
Fast forward to 2010
See what a difference two years of development makes

The camera is behind the cube. The first two moves for the cube are a 360 rotation in X followed by the same on Y, to let the camera see the whole cube. So yes, the video does show the cube scanning and it's included in the time, but blink and you'll miss it.
I wonder if he's glued the lego bits together with polystyrene glue? It's what I do when I want to build a permanent mechanism from lego.

Those are everywhere. Take a look at this: I believe that this is the original, he had to go through quite a bit of troubles. He also made a hanoi solver:
