A grocery store in the small town of La Follette, Tennessee -- population 7,000 -- is at the cutting edge of retailing, as it features a robot that wanders up and down the aisles, helping customers and store employees alike.
The robot, named Marty, works full-time at the local Food Lion store, scanning shelves for out-of-stock products, making sure items are priced correctly and keeping an eye out for any spills on the floor. (Munchies) Picture courtesy of Food Lion.
