Following a line is one of the easiest ways for a robot to navigate successfully and accurately. It's a fixed path, and good programming can provide results that are far more consistent than simply telling the robot where to go without getting a clue.
The 4-channel line tracker sensor provides an easy way to track lines. A line sensor consists of a set of cells, and each cell consists of a transmitter and a receiver.
High compatibility: The sensitivity of each channel can be adjusted individually.
