This is so much less impressive than the Cube Stormer robot tbh. The Cube Stormer does not require these modifications to the cube and scans the cube beforehand, and all that in four seconds. This one just uses six very accurate motors, and moves of the solution translate 1:1 to the motor twists. Nothing special behind that if you ask me.
It looks like it is scanning the cube as part of it's time to me. I'm pretty sure that's required for the GWR.
