Tired of going to the grocery store? In Arizona, a robot-driven car will deliver groceries to your home.

If you live in the Phoenix metropolitan area, you may have already encountered autonomous vehicles delivering passengers from one location to another. Now, Scottsdale, Ariz., residents can have their groceries delivered via robotically driven vehicles, as well. This week Kroger -- the nation's largest grocery chain -- announced a new partnership with Nuro, a Silicon Valley start-up that produces a self-driving, unmanned vehicle known as the R1 that operates on major roadways alongside cars. As of Tuesday, customers have been able to have their groceries delivered to their homes by the autonomous vehicle with a design inspired by a Formula One racing helmet. "Kroger customers are looking for new, convenient ways to feed their families and purchase the products they need quickly through services like pickup and delivery," Yael Cosset, chief digital officer for Kroger, said in a news release.
