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.
This is a prebuilt version of TP-251-003, our programmable triangular omni wheel vectoring robot. It can vector in any direction and is great for indoor robotics. An Arduino Mega and encoders allow for this to be an autonomous robot.
