School’s out. It’s been a long day, so you head home to relax. You’re greeted by a friend who’s happy to see you, listens to you talk about rest, tells you a new joke, helps you put away your school stuff (东西), and reminds you to text your cousin happy birthday. And that’s before he helps you with your homework.

This is your future, and it all starts with a knee-high robot called NAO (pronounced NOW). It kind of looks like you, walks and dances, listens and talks, and even learns and thinks for itself. Its creators predict that the state-of-the-art robot could be a companion at home by the year 2040.

This $16,000 robot recognizes human facial features, so it knows who you are. NAO can even express emotions. It represents the new generation of “autonomous” —or self-guided robots. These robots 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, wheels, or claws, it can’t act. Other robots can move and sense things, but can’t think for themselves. These aren’t self-guided robots. But NAO can do it all.

“You can program your computer to give NAO what could be called personality,” says Natanel Dukan of Aldebaran Robotics, the French company that built NAO. The robot has cute, childlike features — a high voice, small body, big eyes, and a large head. “These are things that are known to have an emotional appeal to people,” robot expert Dan Kara says, “NAO’s friendly design helps in one of NAO’s main functions — to teach people how useful personal robots can be. Someday it may help you pass a test!”
