In elementary school, Glenn Cameron was very aware of the challenges faced by his friend, who was missing a hand. Now Mr. Cameron has built a robotic hand that can be controlled by a human brain.
Mr. Cameron has always liked to build things and learn how things work. But he got more serious after he bought a remote-controlled car. He suddenly realized that he could combine his different skills to give the car new abilities. When he was done, the car could drive by itself without bumping into things.
