Lowe's is testing whether robots can improve customer service in its stores. The machines look like white columns with two large screens on either side of them. They have wheels that allow them move and are equipped with 3D cameras to scan and identify items. Customers can research items they are looking for on the screens, and the robot can lead them to the aisle where an item is located. The robots also have a database of the store's inventory, so they can let customers know whether something is in stock. Lowe's is testing four robots at its Orchard Supply Hardware store in San Jose, California. TheStreet's Scott Gamm reports from New York.
