The Zumo reflectance sensor array provides an easy way to add line sensing or edge detection to a Zumo robot. It features six separate reflectance sensors, each consisting of an IR emitter coupled with a phototransistor that responds based on how much emitter light is reflected back to it. The two outside sensors are positioned at the very edges of the module to maximize their usefulness as edge detectors (e.g. for seeing the white edge of a sumo ring) while the four inner sensors are closer together for better detecting lines.
