Smart Obstacle Avoidance with Line Following 4wd Robot (Unassembled)

Smart Obstacle Avoidance with Line Following 4WD Robot – Complete Arduino Robotics Kit

This product is a complete, versatile 4WD robotic platform designed for hobbyists, educators, and engineers looking to explore advanced Arduino-based robotics. It combines the fundamental capabilities of precise line following with intelligent, dynamic obstacle avoidance. The entire system is built on a robust 4WD chassis and powered by a high-capacity 18650 lithium-ion battery pack, making it a powerful and long-lasting platform for learning and experimentation.

Key Features of the 4WD Arduino Robot Kit

Autonomous Navigation System

This robot can seamlessly switch between autonomous modes. It uses dual IR sensors to track black lines on a light surface with high precision. Simultaneously, its front-mounted ultrasonic sensor on a servo turret allows it to detect obstacles and find a clear path.

Intelligent Obstacle Avoidance via Scanning

Utilizing an HC-SR04 ultrasonic sensor mounted on an SG90 servo motor, the robot doesn’t just stop at an obstacle; it actively scans its surroundings (left, center, and right) to intelligently choose the safest direction to proceed, mimicking natural exploratory behavior.

Powerful 4WD Drivetrain System

A full 4-wheel drive system, powered by an L298N dual H-bridge motor driver, provides superior traction and control across various indoor surfaces, ensuring the robot can make sharp turns and navigate small inclines with ease.

Robust Power System with 18650 Batteries

The robot is powered by three high-capacity 18650 lithium-ion cells in a dedicated holder, supplying consistent, high-current power required for the 4WD system and the servo motor. An integrated on/off switch allows for convenient power management.

Expandable Arduino Uno Platform

At its heart is an Arduino Uno-compatible (SMD version) microcontroller, offering ample I/O for integrating additional sensors, displays, or communication modules. A generous 400-point breadboard is included for easy circuit expansion without soldering.
