Hitachi Ltd. started trials of its EMIEW3 humanoid robot at Tokyo's Haneda airport on Friday to aid foreign visitors to Japan. During the trials through December in the airport's domestic Terminal 2, the robot will communicate with passengers in Japanese and English at a designated information center as well as display information. The industrial conglomerate is hoping to enable the 90-centimeter-tall humanoid robot with autonomous capabilities to guide users to destinations starting around December. At a demonstration on Friday morning, a female foreign passenger asked EMIEW3 for directions to a foreign exchange counter. The humanoid robot at the information center called another EMIEW3 robot to take her to the location.
