Now there are different kinds of robots. Do you want to have one? When you arrive home after a long day's study, a robot greets you and sings sweet songs to you. He would like to help you take your school things to your room. And then he helps you with your homework. He would like to be a good listener when you talk about your school life to him. When your friends birthday comes, he will tell you to call your friend and say "Happy birthday."
This is your possible future life, and the robot's name is NAO. He is from a Guangdong company. NAO has a small body, big eyes and a large head. He can walk and dance. He listens and talks, and he even learns and thinks for himself. His creators predict that the robot will be in people's homes before 2040.
NAO knows how you feel and he can even express emotions (表达情感). He is a self-guided robot. A self-guided robot can sense, think and act. Other robots might do two out of the three. For example, a robot might sense things using cameras and think using computers, but with no arms, he can't act. Another robot can move and sense things, but he cant think for himself. These aren't self-guided robots. But NAO can do them all.
