Tracker module
The working principle of
the tracker module is
similar to the infrared
obstacle avoidance
module. The tracker
module has an
ITR20001/T infrared reflection sensor, of which the infrared transmitter can transmit
the infrared light all the time. When the infrared light is reflected back by the
obstacle, it will be received by the infrared receiver. And the sensor will output the
relative analog value. T
he outputted data are affected by the distance and the color of
the detected object.
The tracker module has 5-channal of infrared sensors. By checking the outputs
from the 5-channel of infrared sensor, the module can judge the position of the
black line, so as to control the action of the smart robot.

please refer to the Tracker Sensor User Manual.
