Line Following Robot

LINE FOLLOWING ROBOT (LFR)

A line following robot is an autonomous vehicle designed to navigate by detecting and following a predetermined path, usually marked by a contrasting line on the floor. It uses sensors, typically infrared (IR) sensors, to continuously monitor the position of the line and send real-time data to a microcontroller, such as an Arduino. The microcontroller processes this data and adjusts the motors' speed and direction via a motor driver to keep the robot on track. This type of robot is widely used in educational settings to teach principles of robotics, electronics, and programming, offering a hands-on learning experience and opportunities for customization and expansion.

Key Components:

1.Arduino Uno Microcontroller:

• • • Acts as the central processing unit.
    • Coordinates all robot movements and sensor readings.
    • Supports easy programming and integration with various components.

2.L293D Motor Driver:

• • • Manages motor speed and direction.
    • Capable of controlling two motors simultaneously.
    • Provides sufficient power and control for smooth navigation across different surfaces.

3. Infrared (IR) Sensors: 

• • • Detects line contrasts on the surface.
    • Sends real-time data to the Arduino for precise path tracking.
    • Ensures the robot stays on course by continuously adjusting its movements.

How It Works:

• Line Detection: IR sensors scan the surface, detecting the contrast between the line and the background.
• Data Processing: Arduino processes sensor input, making decisions to steer the robot.
• Motor Control: Commands are sent to the L293D motor driver to adjust motor speed and direction, ensuring the robot follows the path accurately

So, I tried to make a board that will contain all the components easily and by only adding a power source it'll be activated. The only thing that need to be done is uploading the suitable code .
