4WD Arduino Smart Robotic Car Kit (Un-Assembled)

4WD Arduino Car Kit: Build Your Smart Robot

Bring robotics to life with the 4WD Arduino car kit. This unassembled smart robotic car kit combines a sturdy metal chassis, Arduino UNO control, motor driver, and sensors so you can build, program, and customize a mobile robot for learning or prototyping.

Designed for Learning and DIY Robotics

This Arduino STEM kit is perfect for beginners and hobbyists. As you assemble the chassis and wire the components you will learn mechanical assembly, circuit connections, and Arduino programming. The kit is fully compatible with the Arduino IDE so you can upload sample code or write your own behaviors.

Key Components and Features

• 4-Wheel Drive chassis – Metal platform with four gear motors and rubber wheels for traction and stability on different surfaces.
• Arduino UNO SMD board – The programmable brain with clear pin labels and USB connectivity.
• L298N motor driver – Reliable motor controller that handles power distribution to the motors.
• HC-SR04 ultrasonic sensor – Front-mounted sensor for obstacle detection and avoidance.
• Line-tracking module (2 x IR sensors) – Follow dark lines or predefined tracks using the line sensor array.
• SG-90 servo and IR remote kit – Add pan-tilt movement, steering control, or remote commands.
• Power and connectivity – 3 x 3.7V 18650 Li-ion cells, battery holder, charger, jumpers, cables, and connectors included.

What You Will Learn

• Basic mechanics: assembling chassis, mounting motors and wheels, and secure wiring.
• Electronics: connecting motor driver, sensors, and Arduino sensor shield.
• Coding: upload sketches with Arduino IDE to enable line following, obstacle avoidance, and remote control.
• Troubleshooting and calibration: tune sensor thresholds and motor responses for best performance.

Step-by-Step Assembly Guide

1. Assemble chassis – Bolt metal plates and standoffs together to form the 4WD platform.
2. Mount motors and wheels – Attach gear motors and secure wheels on motor shafts.
3. Install Arduino and driver – Mount Arduino UNO and L298N motor driver on designated standoffs; route wires neatly.
4. Connect sensors – Attach HC-SR04 to the front and mount IR sensors underneath for line tracking; plug into sensor shield.
5. Power up and test – Insert batteries, switch on power, upload test sketches, and calibrate sensor thresholds.
