I not Robot
“Say you had a warehouse with robots running around, this method could help teach the robots how to navigate if the layout of the warehouse stays the same.”
If you had a warehouse with a fixed layout, you wouldn't need AI to control your robots, and the control systems can be very primitive, with corresponding robustness.
As for calling these learning systems "AI", I'll believe it's an AI when you need Dr. Susan Calvin, or Powell and Donovan to diagnose problems when something goes wrong
