It's 20 (or 26 depending how you define a move). See http://cube20.org/
Anyway, finding the 20 moves is very difficult and humans use longer path that are composed of parts that are easier to memorize. Probably the typical length is a few hundred of moves. I guess the robot use a similar system.
But IIRC there are some intermediate methods that use about 50 moves, that are easy enough to calculate by a computer but too difficult for humans.

Thanks.
So even in you used a thousand moves to try and scramble it, it is possible to solve in fewer moves.
