Robots in class

    Over 600,000 children in the United States spend their long time in hospital each year．Many of them say that they have difficult in returning to school after hospital stays．Thanks to technology，kids who are sick in the hospital no longer have to miss time in the classroom．

    A program called PEBBLES makes it possible for kids in hospital to take part in classroom discussions by using robot．PEBBLES(Providing Education by Bringing Environments to Students)supplies robots to help kids who are staying in hospital keep up with their classmates．

    For Achim Nurse，a 13-yers-old patient at Blythedale Children’s Hospital in Valhalla，New York，PEBBLES helped him so much．When he first learned about the program，he wasn’t so sure it would work．    

   “When I first saw it，it looked difficult，”said Achim．

    However，after 30 minutes of working with the robot，Achim discovered that he had gotten good at operating it．

    The robots work in pairs—一one in the hospital with the student，the other in the classroom．

    The robot in the classroom gives the student in the hospital a feel of“tele-presence．”A live picture of the students is shown on a video screen in the classroom．Meanwhile，in the hospital room，the student knows clear about what is going on in the classroom．

    The robot at the school has four wheels．so it can move around from class to class．Its“face” is an auto-focus(可以自动调焦的)camera．By using a control box，the student call turn the robot’s head，raise its hand，and adjust the volume(音量)．It is even equipped with a scanner(扫描器)and printer，so if the teacher want to have an exercise or testing class，the student can participate from the hospital．

   “The robot is greeted by students in the classroom．It is also greeted by the sick student。”said Andrew Summa，national director of the robot project．
