Tennessee high school students build robotic hand for classmate

Students designed, 3D printed and sized a prosthetic hand for Sergio Peralta, whose right hand is not fully formed

Students at a Tennessee high school have built a robotic hand for a classmate missing part of his, an act of friendship that he has called life-changing.

At the center of perhaps one of the most heartwarming news stories to come out of the US so far this year is Sergio Peralta, who initially arrived at Henderson high school near Nashville this past fall while trying to cover up that his right hand was not fully formed, CBS News reported Wednesday.
