The stores are just an experiment, so human retail workers still have a little breathing room before the robot takeover begins. Pepper was first introduced as a humanoid robot by SoftBank in 2014. The robot is projected to work in people’s homes. Pepper robot went on sale in June 2015 for $2,000 each unit. It sold out and was a success. Now, SoftBank is also launching four Pepper for Biz Atelier locations in Tokyo, Osaka, Aichi and Fukuoka. The SoftBank robot-staffed store will be in operation from March 28 to April 3, from noon to 7 p.m. local time. “I don’t know how this will turn out, but it should be a quite interesting experiment,” SoftBank CEO Ken Miyauchi told to the media during the Pepper World 2016 conference in Japan.
