This is my first project using RobotC. My robot is a cleaning robot. When it senses a white piece of paper, it will move from side to side and "clean" that piece of paper. Once it is done cleaning, it will keep driving around until it finds another piece of white paper, and it will clean it too. It will continue to do the same thing over and over until you stop it.
Here is a video of my robot: http://www.flickr.com/photos/29464331@N02/4117559442/in/set-72157608737193431/
