The idea of introducing robots in parking garages is nothing new. As it turns out, a robotic parking garage has opened in Nanjing, China. The automated guide vehicle parking garage is pretty easy to use. Customers will have to book a parking lot space on their smartphone, drive their car to the entrance, and let robots do the parking.
The system is monitored by an operator. Once the floor opens and the car is lowered, it is placed on robotic tracks and guided to a parking space. RT has shared more info about this robotic system here.
