As technology develops, school students who are off class may have no fear of too much absence from class. A small robot may help those children recovering from a long-term illnesses in the hospital or at home. These children may feel isolated from their friends and classmates. The robot takes their place at school. Through the robot, the children can hear their teachers and friends. They also can take part in class from wherever they are recovering.

Anyone who has had a long term illness knows that recovering at home can be lonely. This can be especially true of children. They may feel left out. Now these children may have a high-tech friend to feel less alone. And that friend is a robot. The robot is called AV1. AV1 goes to school for a child who is at home while recovering from a long-term illness. And the child’s school friends must help. They carry the robot between classes and place the robot on the child’s desk.

A Norwegian company called No isolation created the robot. The co-founders of No Isolation are Karen Dolva and Marius Aabel. Dolva explains how the robot AV1 works. She says, from home, the child uses a tablet or phone to start the robot. Then they use the same device（设备）to control the robot’s movements. At school, the robot becomes the eyes, ears and voice of the child. The child can take part in classroom activities from wherever she/he is recovering-whether at home or from a hospital bed. The robot is equipped with speakers, microphones and cameras make communicating easy.
