RALEIGH (WTVD) -- A North Carolina State University graduate ran into a road block when he was working on his senior engineering project, and out of that he created a muscle sensor.
It can control video games, robots, and can even help stroke patients.
Imagine his surprise, though, when one of the biggest stars on the planet gave a prosthetic arm to a little boy with his muscle sensor in it.
