Line-Following Robo – Goods Mover

About  The Project:

Have you ever seen robots that help move boxes in big warehouses? Now, you can build a mini version! This little robot will follow a black line on the ground to move from one place to another, just like real robots in factories and warehouses. It’s a fun way to learn how robots follow paths!

We can enhance our robot by adding an ultrasonic sensor to detect obstacles and stop automatically, and by controlling it with an IR remote for manual operation

Components Needed

1. ATmega328P-ELF Mainboard (The brain of the robot)
2. Double-way Line-following Sensor (To detect and follow the black line)
3. Motors & Wheels (To move the robot)
4. USB Cable (To connect to the laptop for programming)
5. Ultrasonic Sensor (Optional – To detect obstacles and stop automatically)
6. IR Receiver & IR Remote Control (Optional – For manual operation and control)

Pseudo Code:

# Initialize Libraries and Components
Initialize line-following sensor
Initialize ultrasonic sensor
Initialize motors and wheels
Initialize IR receiver (optional)
Initialize IR remote (optional)

# Start the robot movement
While robot is running:
    Read line-following sensor data
    If sensor detects line:
        Move robot forward
    Else:
        Turn robot to stay on the line
    
    # Obstacle detection
    If ultrasonic sensor detects obstacle:
        Stop robot
        Wait for 1 second
        Avoid obstacle (turn or move back)
    
    # Optional: Manual control via IR remote
    If IR receiver receives signal:
        Follow manual control commands from remote
