Robotics technology has evolved over the years, but systems that can hold a sophisticated conversation with a human may still be far off.
Osaka-based Vstone Co. and professors at Osaka University are adopting a different approach: getting people to speak to more than one robot simultaneously.
They unveiled two models of robot designed for that purpose Tuesday in Tokyo. The two robots, both about 30 cm in size and weighing 900 grams, are named CommU and Sota. They are the work of professors Hiroshi Ishiguro and Yuichiro Yoshikawa and Vstone.
