Rubik's Cube Solving Robot?

The method to solve Rubik's Cube is well known and based on simple group theory. So, it's quite possible that this robot really does solve it automatically.

However, I can't help but think "What if they had the machine perform a random set of rotations beforehand and then this video is just showing the robot running those rotations in reverse?".

There is a flash and a pause in the action at one point, implying the robot is looking at the current configuration and working out the right moves, but I'm going to take it with a large grain of salt, anyway.
