Aftera long day's study at school, you are very tired. So after school you go hometo relax. When you get home, a robot greets you. He is happy to see you andhelps you take your school things to your room. He listens to you talking aboutyour school life and tells you a new joke. And he tells you to call your cousinand to say "Happy Birthday". And then he helps you with yourhomework.
Thisis your future, and the robot's name is NAO. NAO has a small body, two big eyesand a large head. He can walk and dance. He can listen and talk, and he caneven learn and think for himself. His creators (创造者) predictthat this kind of robot will be in people's homes before 2040.
This robot is $16，000. He knows who you are. NAO can even express his emotions(情感). He is a self-guided robot. A self-guided robot can sense (感觉)，think and act. Other robots might do twoout of the three. For example, a robot might sense things using cameras andthinks using computers. But with no arms, he can't act. Another robot can moveand sense things, but he can't think for himself. These aren't self-guidedrobots. But NAO can do them all.
