Japanese firm Softbank has unveiled a robot called Pepper, which it claims can actually read human emotions. It uses an "emotional engine" and a cloud-based artificial intelligence system that allows it to analyse gestures, expressions and voice tones. The firm said people could communicate with it "just like they would with friends and family" and it could perform various tasks. It will go on sale to the public next year for 198,000 yen ($1,930; £1,150). "People describe others as being robots because they have no emotions, no heart," Masayoshi Son, chief executive of Softbank, said at a press conference. "For the first time in human history, we're giving a robot a heart, emotions." The firm will display prototypes of the robot at two of its stores from Friday, allowing customers to interact with them.
