There goes a job. I had never encountered a robotic parking garage until last weekend in Fort Greene, Brooklyn. (By the way, Fort Greene was once a scary place. Not anymore. Very pleasant, with a perfect cozy neighborhood Italian joint, Belli on Fulton St.)
The garage had rack parking 3 floors underground. You park the car on the elevator, get out, and down it goes. When it's time to go, you watch the robot lift your car off the rack on the video camera. Robot places your car on the elevator, and up it comes.
