Manufacturers in the U.S., where workers typically have been abundant and wages stable, have been slower to embrace robotics than those in some other industrialized countries. The number of robots deployed in the U.S. per 10,000 workers has traditionally trailed countries such as South Korea, Japan and Germany, according to the International Federation of Robotics.
