In this Friday, Jan. 11, 2013, photo, Webb Wheel Products employees watch as the Doosan V550M drills holes in one side of a 130-lb CK drum without help from humans at Webb Wheel Products in Cullman, Ala. Webb Wheel hasn't added a factory worker in three years, though it's making 300,000 more drums annually, a 25 percent increase, because of robots. (AP Photo/Dave Martin)
