This video will show you everything you need to know about building a simple "Line Follower Robot Car Using Arduino".
In fact we have used very simple and readily available components in the market to build this line following robot car.
Let's see what are the parts we have used in building this DIY line follower robot car using arduino;
Components/Parts Required:
1. UNO R3 board, USB Cable
2. L293d motor driver shield for uno r3
3. Complete 2wd Car Chassis with motors and wheels
4. Infrared Sensor x 2
5. 4 cell AA Battery holder with ON-OFF switch
6. Female - Female jumper wires
7. Black Tape
8. L-Clamp x2
About Line Follower Robot:
A line follower robot is a robot which follows a certain path controlled by a feed back mechanism from the line sensors. You can build a line following robot car using 2 sensor, 3 sensor or even upto 8 infrared sensors based on your need.
Working Principle of Line Follower Car:
In this project, we have designed an Arduino based Line Follower Robot. The working of the project is pretty simple. Detect the black line on the surface and move along that line. The detailed working is explained here.
We need infrared sensors to detect the line. For line detection logic, we used two IR Sensors, which consists of IR LED and Photo diode. They are placed in a reflective way i.e. side - by - 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.
In case of black surface, which has a low reflectance, the light gets completely absorbed by the black surface and doesn’t reach the photodiode.
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.
When the robot moves forward, both the sensors wait for the line to be detected. For example, if the IR Sensor 1 detects the black line, it means that there is a right curve (or turn) ahead.
Arduino UNO detects this change and sends signal to motor driver accordingly. 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.
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. 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.
Arduino UNO continuously monitors the data from both the sensors and turns the robot as per the line detected by them.
Uses of line follower robot car:
- Line follower Robots are commonly used for automation process in industries, military applications and consumer applications.
- Industrial Applications: These robots can be used as automated equipment carriers in industries replacing traditional conveyor belts.
- They are very useful as they can work without any supervision i.e. they work as automatic guided vehicles.
- With additional features like obstacle avoidance and other security measures, line follower robots can be used in driver less cars.
- Automobile applications: These robots can also be used as automatic cars running on roads with embedded magnets.
- Domestic applications: These can also be used at homes for domestic purposes like floor cleaning etc.
