2WD Arduino Line Following Robot (Unassembled)

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.
