Which sensor is used to follow the line for a line follower robot?

IR sensors
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.

Which component will help the line following robot to move forwards?

The vision sensors (as shown in figure 7) are the most important components of the robot architecture as they help with the detection of the path, and in turn, allow the robot to move forward.

How do line sensors work?

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. The sensor has a 3-pin header which connects directly to the RedBot Mainboard via female to female jumper wires.

How are IR transmitters used in line follower robots?

In this arduino based line follower robot we have used IR Transmitters and IR receivers also called photo diodes. They are used for sending and receiving light. IR transmits infrared lights. When infrared rays falls on white surface, it’s reflected back and catched by photodiodes which generates some voltage changes.

How is a line sensor used in a robot?

That means you have an arbitrary line drawn on the floor and the robot tracks it by moving right along it! The line is sensed using a piece of hardware called a line sensor. A line sensor can be easily made using a low cost IR Rx/Tx pair. The IR Rx emmits IR radiation and the Rx helps in receiving the waves.

Can a line sensor be made using IR?

A line sensor can be easily made using a low cost IR Rx/Tx pair. The IR Rx emmits IR radiation and the Rx helps in receiving the waves. See the figure below for working of line sensor. Schematic for Line Sensor. Actual IR Rx Tx Pair.

How is an IR sensor connected to an Arduino?

The IR sensor is a 3 three wired sensor, in which the brown and the black wire are used to connect the sensor to the power supply, whereas, the red wire is connected to the load, or Arduino, in our circuit. The load wires of the IR sensors are connected to pin 8, 9 and 10 as shown in the schematic.
