Just rode the Skylink at DFW and, gazing out the window at a dozen luggage carts, meal carts, fuel trucks and the like, all scurrying to and fro from gate to gate, I see potential for significant automation. Specifically, I was reminded of Amazon’s factory automation. Why not automate all those airport vehicles? They would operate in a closed space so not many pedestrians or “rogue” vehicles to worry about; plus they could apply any number of signs or painted patterns to assist computer vision systems.
And we could have UAV’s flying us around in a few years too.
