In this Thursday, Jan. 24, 2013 photo, Winchester Elementary School teacher Dawn Voelker carries a robot up the stairs that is being operated by Devon Carrow while he is attending school at in West Seneca N.Y. Carrow's life-threatening allergies don't allow him to go to school. But the 4-foot-tall robot with a wireless video hookup gives him the school experience remotely, allowing him to participate in class, stroll through the hallways, hang out at recess and even take to the auditorium stage when there's a show.
