A hundred humanoid communication robots called Robi perform a synchronized dance during a promotional event called 100 Robi, for the Weekly Robi Magazine, in Tokyo, in this January 20, 2015 file photo. Three-fourths of robot installations over the next decade are expected to be concentrated in four areas: transportation equipment, including the automotive sector; computer and electronic products; electrical equipment and machinery. Labor costs have climbed in countries such as China that have been popular for outsourcing production, while technological advances for robots allow them to be more flexible and perform more tasks.
