Would you trust a robot to park your car? The question will confront New Yorkers in February as the city’s first robotic parking opens in Chinatown.
[9] The technology has been successfully applied overseas, but the only other public robotic garage in the United States has been troublesome, dropping vehicles and trapping cars because of technical problems.
[10] Nonetheless, the developers of the Chinatown garage are confident with the technology and are counting on it to squeeze 67 cars in an apartment-building basement that would otherwise fit only 24, accomplished by removing a maneuver space normally required.
A human-shaped robot won’t be stepping into your car to drive it. Rather, the garage itself does the parking. The driver stops the car on a flat platform and gets out. The platform is lowered into the garage, and it is then transported to a vacant parking space by a computer-controlled device similar to an elevator that also runs sideways.
There is no human supervision, [11] but an attendant will be on hand to accept cash and explain the system to new users. [12] Parking rates will be attracted about $400 monthly or $25 per day, according to Ari Milstein, the director of planning for Automation Parking Systems, which is the U.S. subsidiary of a German company. This company has built automated garages in several countries overseas and in the United States for residents of a Washington, D.C. apartment building.
