Similar to the PaperBot IR shield, but made to fit the Goliath Robot perfectly. Can also be used with any 3DoT robot of your own making, of course.
QRE1113 Reflective Optical Sensors measure reflectivity to detect a change in color, material or distance. The two inner sensors on the IR Sensor Shield are at the perfect distance to follow a ~0.5″ thick line. The two outer sensors can be used to detect intersections and to aid in turning your robot.
