American grocery chain, Walmart, has delegated the mundane job of restocking shelves to their new instore robot which is programmed to detect when stock gets low. It has been reported that the robot that roams the aisles all day scanning shelves performs the task 50% better than employees. The two-foot tall robots are fitted with cameras to scan aisles and check stock, identifying missing, misplaced, mislabelled and mispriced items. The robots can then send that information to employees who will ultimately fix the issue at hand. Is this something we will likely see in all supermarkets in the near future?
