Childhood is a happy time, right? Not necessarily. Consider these facts.

Depression(抑郁症) may occur in as many as 1 in 33 children.

    Once a child has an episode of depression, he or she has a 50 percent chance of experiencing another episode in the next 5 years.

    Suicide(自杀) is the 6th leading cause of death for 5-to-15-year-olds.

    If your child experiences 5 or more of these signs or symptoms for at least 2 weeks, he or she may be experiencing depression or mental illness.

    Sometimes, a child who causes problems at school or at home may actually be depressed, according to the American Academy of Child and Adolescent Psychiatry.

    If you think your child may be depressed, it's important to have your child treated. Discuss your child's problems with his or her doctor. The doctor may suggest a referral to a children's psychologist or psychiatrist.

    Anyone who has had a long-term illness knows that recovering at home can be lonely. This is can be especially true of children. They may feel isolated（孤立的）from their friends and classmates. Now, a small robot may help children who are recovering from a long-term illness in the hospital or at home. The robot takes their place at school. Through the robot, the children can hear their teachers and friends. They can also take part in classroom activities from wherever they are recovering – whether at home or from a hospital bed.

    The robot is called AV1.It is created by a company called “No Isolation”. 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.

    Dolva, one co-funder （创始人）of No Isolation, explains how the robot AV1 works. She says, “the robot sits at the child's desk in the classroom and the child at home uses a tablet（平板电脑）or a phone to start it, control its movement with touch, and talk through it. So the robot becomes the eyes, the ears and the voice of the child at school.” The robot is equipped with speakers, microphones and cameras that make communicating easy. Moreover，The AVI was designed to be tough. It is water-resistant(防水) and can take a fall from a desk without damage. Inside AV1 is a small computer connected to a 4G network. AV1 is large and looks like a human for a reason. Dolva thinks this is important because the robot is expected to be a friend to the children.

    The robot just became available to the public. Hopefully AV1 will help some children feel less lonely while they are absent from class.
