Rohan Agrawal is only 12 and he builds robots, including a version of the roomba, the iRobot that sweeps and vacuums. Of course, being only 12, Agrawal's version of the robot is not designed to do household chores but rather, deliver potato chips.

Agrawal taught himself programming at age 4 and has never looked back. 

Meet Agrawal in the video below.
