In the above video, animator and mechanical designer Pat Starace presents the ultimate kid-friendly prosthetic. Based on the design of Marvel superhero Iron Man's crime-fighting robotic armor, the hand seems to have full functionality and a bold sense of style.
In addition to giving a child all the range of movement expected from an artificial arm, the prototype in the video is outfitted with a Bluetooth connection, battery and charger, and Arduino technology. The Arduino is a simple computing tool, and gives the hand basic sensors so it can react to specific movements. In this case, the sensors allow the wearer to shoot pretend lasers by performing Iron Man's signature hand gesture.
The goal, Starace told Mashable, is to raise kids' self-esteem to "superhero levels." The device hasn't been tested by a pint-sized hero yet, but Starace says it's ready to go.
