In a show of true-blood superheroism, real-life hero Albert Manero asked Robert Downey, Jr. for help in making a bionic arm for a child who is missing his right arm from just above his elbow. Recently, Downey presented a robot arm (from one of his many Iron Man suits, it seems), to young Alex Pring from Central Florida, with the help of Microsoft’s Collective Project and Manero’s own Limbitless Solutions.
