2WD Arduino Line Following Robot (Unassembled)

Product Overview

The 2WD Arduino Line Following Robot (Unassembled) is an educational DIY robotics kit designed to teach robot motion, sensor integration, feedback control, and autonomous navigation. Built around an Arduino UNO controller and a dual IR sensor array, this kit follows a high-contrast line on a flat surface and is ideal for students, beginners, and hobbyists learning embedded systems and Arduino programming.

Key Features

• Arduino-Based Line Follower: Arduino UNO interprets sensor data and makes navigation decisions.
• Dual IR Sensor Module: Detects black-on-white or white-on-black line contrasts for reliable tracking.
• 2WD Drive System: Two-wheel differential drive provides smooth turns and responsive control.
• Educational DIY Kit: Unassembled format forces hands-on wiring, calibration, and code customization.
• Customizable Behavior: Modify Arduino code to tweak speed, sensor sensitivity, and steering algorithms.
• Expandable Platform: Supports add-ons such as Bluetooth modules, ultrasonic sensors, and obstacle-avoidance systems.
• Durable Acrylic Chassis: Transparent base plate with pre-drilled holes for straightforward assembly.

Specifications

• Controller Board: Arduino UNO R3
• Motor Driver Module: L298N (compatible with L293D)
• Sensor Module: Dual IR Line Tracking Sensor Module
• Motors: 2 × DC Gear Motors (3–12V)
• Wheels: 2 × High-traction Rubber Wheels
• Chassis Type: Acrylic 2WD Platform
• Caster Wheel: 1 × Universal Caster Wheel
• Power Supply: 2 × 18650 Li-ion Batteries (battery holder included)
• Operating Voltage: 5V to 12V
• Assembly: Unassembled Kit (DIY)

How It Works

1. The IR sensors detect contrast between the line and the background surface.
2. The Arduino UNO reads the sensor values and processes the data in real time.
3. The motor driver (L298N) controls motor speed and direction based on Arduino commands.
4. The robot steers left, right, or moves forward to stay aligned with the track.
