When we are ill, we have to leave school and stay at home or in hospital. We can't study or play with our classmates. That makes us sad and bored.

Now Norwegian(挪威的) scientists make a robot who can help these children. This robot is called AVI. When the ill child leaves the school, AVI will sit at the child's desk in the classroom. The child uses a phone to start it at home. The robot becomes the eyes and ears of the child. Through the robot, the child can hear and see his or her teachers and classmates. It's helpful and useful.
