A small robot may help children who are recovering（恢复）from long-term illnesses（疾病）in hospital or at home. Those sick children may feel lonely without their classmates around. Then the robots take the place of them at school. Through the robots, the children can hear their teachers and friends. Most importantly, they feel less lonely while they are not in class.

A Norwegian company called No Isolation created the robot. It is called AVI. AVI goes to a school for a child who is unable to leave home. And the child’s classmates must offer some help. They carry the robot between classes and put the robot on the child’s desk. It’s not difficult. At home, the child uses a computer or a phone to start the robot. Then he uses the same computer or phone to control the robot. At school, the robot becomes the eyes, ears and voice of the child. The best part is that the child can even join in classroom activities. The robot has speakers, microphones and cameras. Those things make communication easy.

AVI looks like a human. Scientists say this is important. The robot should be a friend of children. It can’t just be a small camera and let someone put it in a place. With AVI’s help, people think that children who can’t go to school will feel happier while they are at home.
