    A Japanese telecom company has designed a robot that it says has emotions (情绪). But rather than run in fear from it, we've welcomed it into our homes: Pepper, the “emotional robots” sold out within a minute of going on sale.

    Created by Aldebaran Robotics and Japanese mobile giant SoftBaok, Pepper went on sale to the general public in Japan on 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, there's 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 “multi-layer neural (神经的) network.” Pepper's touch sensors and cameras are said to influence its mood, which is displayed on the tablet-sized screen on its chest.

    Pepper will sigh when unhappy, and can go around your house recording your family's daily activity. Aldebaran says Pepper can feel “joy, surprise, anger, doubt and sadness,” but it doesn't say how strongly it can feel these emotions. What happens when Pepper is having a bad day? Will it, like many humans, 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, you'll be safe if you can make it upstairs.

    Aldebaran says in reality, they're probably quite a few years away from artificial intelligence that could create real emotions. Aldebaran wasn't immediately able to tell when Pepper will be available out of Japan, but additional sales are scheduled for July after the first 1,000 units sell out. SoftBank currently uses the robots in its stores as greeters, and it plans to offer Pepper to other stores in the future. Hopefully “boredom” is not an emotion Pepper can feel.
