OMG Parallax's Feedback 360 Servo would be so perfect for This
I'm mad I didn't think of it! A 3-servo, self-solving Rubik's Cube!

Next time I see it, I will then point to this video as an example of someone who is actually smart.
I wondered that myself, so I ran the question past a blindfold cuber I know.... his comments :
"It's definitely solving it and not reversing the scramble - you can tell this because it's just using an implementation of a 'human' algorithm (where you see lots of partial blocks built up along the way, and a large number of moves, vs a good computer algorithm or reverse scramble, both of which would be very few moves and appear to do nothing sensible for a while before suddenly everything falls into place)
The problem of solving it in the least moves is quite well studied - you only need 20 at most, and most scrambles do need 20 moves. There have been computer implementations of minimum move solvers for years, and more recently some heavy computation on some Google clusters showed the 20 move bound for any of the (absurdly large number of) possible scrambles"
Holy ****!
Yes! I am surprised it holds together.
