For the robot to turn left, the motor on the left side of the robot is slowed down (or can be stopped completely or can be rotated in opposite direction) and the motor on the right side is run at normal speed.ДЄrduino UNO continuously monitors the data from both the sensors and turns the robot as per the line detected by them. Similarly, when the IR Sensor 2 detects the black line first, it means that there is a left curve ahead and the robot has to turn left. In order to turn right, the motor on the right side of the robot is slowed down using PWM, while the motor on the left side is run at normal speed.

For example, if the IR Sensor 1 in the above image detects the black line, it means that there is a right curve (or turn) ahead.ДЄrduino UNO detects this change and sends signal to motor driver accordingly.

When the robot moves forward, both the sensors wait for the line to be detected. Using the same principle, we will setup the IR Sensors on the Line Follower Robot such that the two IR Sensors are on the either side of the black line on the floor. In case of black surface, which has a low reflectance, the light gets completely absorbed by the black surface and doesnвЂ™t reach the photodiode.

As the reflectance of the light coloured surface is high, the infrared light emitted by IR LED will be maximum reflected and will be detected by the Photodiode. The following image shows the working of a typical IR Sensor (IR LED вЂ“ Photodiode pair) in front of a light coloured surface and a black surface. side вЂ“ by вЂ“ side so that whenever they come in to proximity of a reflective surface, the light emitted by IR LED will be detected by Photo diode. For line detection logic, we used two IR Sensors, which consists of IR LED and Photodiode. The detailed working is explained here.ДЄs mentioned in the block diagram, we need sensors to detect the line. The working of the project is pretty simple: detect the black line on the surface and move along that line. In this project, we have designed an Arduino based Line Follower Robot. These motors provide more torque than normal motors and can be used for carrying some load as well. Motors (Geared Motors): We have used two geared motors at the rear of the line follower robot. Hence, choose the appropriate power supply which is sufficient for all the components including the motors. Note: The power supply to the motors must be given from the motor driver IC. It receives signals from Arduino based on the information from the IR Sensors.

Motor Driver (L293D): L293D Motor Driver IC is used in this project to drive the motors of the robot. The data from the sensors (IR Sensors) will be given to Arduino and it gives corresponding signals to the Motor Driver IC. The working of the IR Sensor and its scope in this project will be explained in the actual working of the Line Follower Robot.Д¬ontroller (Arduino UNO): Arduino UNO is the main controller in the project. In case you do not have one, you can make your own sensor using the following circuit. It consists of an IR LED and a Photo diode and some other components like comparator, LED etc.ДЄs mentioned earlier, we have used a pre вЂ“ assembled IR Sensor.

Sensors (IR Sensor): We have used IR Sensor Module as the line detecting sensor for the project. The following image shows the block diagram for line follower robot. The line follower robot built in this project is divided in to 4 blocks.

If you do not have this, we have explained how to build one yourself. Note: We have used a prebuilt IR Sensor Module that consists of an IR LED and a Photo Diode. Black Tape (Electrical Insulation Tape).
