LEGO Mindstorms NXT Ball Hunter

This robot's mission is to find the red ball and to grab onto it.  You can place both the blue and red balls anywhere near the robot to start with, and the robot will try to find the red ball and grab it.  It uses the ultrasonic sensor to locate the nearest ball, then it uses the light sensor to tell the red ball from the blue ball.  If it finds the blue ball first, it will push it out of the way then go on to try to find the red ball.
