Nexi is one of a new generation of robots. It moves on wheels and can pick up objects. But robots like Nexi are more than just entertaining toys.

Nexi, a social robot created by scientists at the Massachusetts Institute of Technology (MIT) , can express human emotions. Roboticists at MIT call Nexi a "social robot". A social robot is a robot that can communicate like a human. Nexi can look sad, mad, and even bored. Some social robots can also "read" our facial expressions. Roboticists believe that it won't be long before we have social robots in our homes, helping us live better lives.

Autom is another social robot developed at MIT. Autom is a robot health coach. It has a screen where you enter information about what food you ate that day or how much you exercised. Autom has a face with eyes that move. It speaks with a synthesized voice. Autom gives you advice about your diet and exercise and drives you to do better.

In a test, Autom helped people lose weight better than other ways of recording diet information. Roboticists think this is because Autom used facial expressions and words of encouragement. In other words, Autom communicated like a real person. In fact, many people who used Autom gave the robot a new name and talked to it. When robots use human expressions and body language, people reply to them a lot like they reply to people.

In the future, humans may communicate with social robots just like they do with other people. Let's wait and see what will happen in the future!
