That almost certainly wasn't technically AI. The actual solving (deciding what moves are required) has been a trivial problem for decades and can be solved with a simple computer program in milliseconds. But it is a mathematical problem not an intelligence one, so doesn't really qualify as AI.
It is of course possible that real AI software was used, but highly unlikely given that mathematical solutions exist.
The rest of the machine is robotics, ie tools to physically scan the cube to see its current state and then to manipulate it to a new state. Again, not really AI.
The speed at which it appeared to solve it, was a feat of robotics not AI as the actual planning for what moves are required can be done in miliseconds.

The program that did very well at Go, does qualify as an AI.
