East Japan Railway Co. on Wednesday showed the media a test trial of two artificial intelligence robots designed to guide passengers at Tokyo Station. The robots -- Pepper of SoftBank Robotics Corp. and SEMMI of German railway company Deutsche Bahn AG -- were deployed at an information desk in a shopping and dining center called Gransta on the basement floor of the station. Visitors can ask for directions to stores and restaurants in the facility in languages including Japanese, English and Chinese, JR East said. The trial, which began Monday and will last through May 31, comes as part of a technological exchange between JR East and Deutsche Bahn that began in 1992. They will look at the machines' capabilities and visitors' reactions to their appearance.
