　　Whether in the home or the workplace, social robots are going to become a lot more common in the next few years.Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

　　While household robots today do the normal housework, social robots will be much more like companions than mere tools.For example, these robots will be able to distinguish when someone is happy or sad.This allows them to respond more appropriately to the user.

　　The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant.You can talk to the robot, ask it questions, and make requests for it to perform different tasks.The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household.It can do things such as reminding an elderly family member to take medicine or taking family photos.
