Function : 

A line tracker mostly consists of an infrared light sensor and an infrared LED.

It functions by illuminating a surface with infrared light; the sensor then picks up the reflected infrared radiation and, based on its intensity, determines the reflectivity of the surface in question.

Lightly colored surfaces will reflect more light than dark surfaces; therefore, lightly colored surfaces will appear brighter to the sensor.

This allows the sensor to detect a dark line on a pale surface, or a pale line on a dark surface.

Applications :

The line tracker enables a robot to autonomously navigate a line-marked path.

By drawing a line in front of a robot outfitted with a line tracker, one can dictate the robot’s patch by showing it where to go without using a remote controller.

A typical application uses three line trackers, with the middle sensor aligned directly above the intended line.

Compatibility :

• All VEX Microcontrollers.
• 3-Wire Extension Cables.

Caracteristics :

• Navigate down a marked path.
• Use for light sensing.
• More autonomous function.
