It's probably got some AI but not the GPU gobbling kind. This is old school robotics using control loops and old AI algorithms. Sensors decide if you've parked correctly in the garage. Robot is dispatched via a queue once you've closed the door. Cameras and sensors guide the dolly into place. Robot follows predetermined route to the parking spot and uses sensors to detect obstructions (people, debris, other robots parking cars). Maybe there's lidar on board. Cameras and encoders guide the car perfectly into the designated spot. Robot whisks off to go charge or grab another car from the queue. It's effectively the same level of intelligence as a Roomba with the mechanics of an electric forklift. It's still cool but the fundamentals were developed 40+ years ago, we've just managed to shrink a lot of the tech down in size and power since then.
