West Seneca, N.Y. — In an elementary school hallway, a teacher takes her second-graders to the library, leading a single-file line of giggling boys and girls that's perfectly ordinary until you get to a sleek white robot with a video screen showing the face of a smiling, chubby-cheeked boy.Devon 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.
