Walmart tests new robot at Burbank store

The robot, which looks like a trash bin on wheels with a periscope jutting out of its top, gathers its data by using dozens of lights, cameras, both 2D and 3D, as well as lasers to recognize the products and bar codes it is scanning. As it goes down each aisle, it creates images of the shelves and relays that information to store employees, said Martin Hitch, chief business officer for Bossa Nova.
