But rather than run in fear from it, weve welcomed it into our homes: Pepper, the “emotional robot”， sold out within a minute of going on sale.Created by Aldebaran Robotics and Japanese mobile giant SoftBank, Pepper went on sale to the general public in Japan June 20. It is “the first humanoid(类人的) robot designed to live with humans，” Aldebaran says on its website. Pepper costs about $1，600. And like all good mobile products, theres a $120 per month data fee, as well as an $80 per month damage insurance fee. According to a news report, Pepper can pick up on human emotions and create his own using a “multilayer neural(神经的) network.” Peppers touch sensors and cameras are said to influence its mood, which is displayed(展示) on the tabletsized screen on its chest.Pepper will sigh when unhappy, and can go around your house recording your familys daily activity. Aldebaran says Pepper can feel “joy, surprise, anger, doubt and sadness”， but it doesnt say how strongly it can feel these emotions. What happens when Pepper is having a bad day? Will it like manyhumans, become uncooperative? Will it ask for some time alone? What happens if it knows that its purpose in life is just to take part in small talk? Thankfully, Pepper is only about four feet tall, with roller balls instead of legs, so if it is angry with and even turns on its owners, youll be safe if you can make it upstairs.Aldebaran says
