What does a line follower do vex?
The VEX Line Tracking Sensor allows the robot to tell objects or surfaces apart based on how dark or light they are. It shines a beam of infrared light out onto the object, and measures how much light is reflected back. The Line Tracking Sensor is an analog sensor, and it returns values in the range of 0 to 4095.

How do you make a VEX robot follow a line?
Open the Motors and Sensors Setup menu, and go to the Analog Sensors tab. Select Robot > Motors and Sensors Setup to open the Motors and Sensors Setup menu. Click the “VEX 2.0 Analog Sensors 1-8” tab on the Motors and Sensors Setup menu. Use the dropdown list to make “Line Follower” the sensor type.
What is a line following sensor?
The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED.
Is a line tracker analog or digital?
The Line Tracker is an analog sensor which means the infrared sensor will return a value anywhere between 0v and 5v of voltage to the V5 Brain depending on the reflected infrared radiation.
How does a line tracking module work?
Line tracking works by detecting a difference in the amount of reflection between the line you are trying to follow and the adjacent surface of the floor. The line can either be more or less reflective than the surrounding surface, what is important is that there is a difference which can be detected.
How does a line follower works?
A line follower consists of an infrared light sensor and an infrared LED. It works 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.
Which sensor is best for line follower robot?
QRD1114 IR reflective line/object sensor and CNY70 reflective optical sensor are the most commonly used sensors for line follower robots. The CNY70 is a reflective sensor that includes an infrared emitter and phototransistor in a leaded package which blocks visible light.
How do line tracker sensors work?
The line tracking sensor works by detecting reflected light coming from its own infrared LED and by measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it.
Which sensor is using a line follower?
In case of a line follower robot we use IR transmitters and receivers also called photodiodes. They are used for sending and receiving light. IR transmits infrared lights.
Which sensors are used in line following robot?
4} IR SENSOR For line sensing operation, IR sensors are the one which are widely used for the development of a line follower robot. There are some basic things to follow where white surface of the black line reflects light and the black line receives it after the transmission.
