Pepper can examine face expressions，human voice and signs，then make an answer．Pepper is designed to be a family robot，but it isn't like Rosie，the household robot on the cartoon．Pepper is used at home or in the store，where we provide fun and entertainment．

Pepper was on sale in Japan for around ＄2.000 in February，2015．For now，several Peppers are at Softbank stores in Tokyo for people to visit．The creators say before selling Peppery they want the robots to store more knowledge，so it can get along better with humans．
