Arduino DIY Smart Robot Car Kit | STEM Educational Coding Robot for Kids and Makers | Ultrasonic Obstacle Avoidance & Infrared Line Tracking with Dual Motor Drive | Programmable Platform Supporting Arduino IDE, Scratch & Mixly with Bluetooth Expansion

The DIY Wooden Smart Robot Car Kit is a hands-on educational platform designed for students, hobbyists, and educators who want to explore the foundations of STEM robotics, coding, and automation through interactive learning. This programmable robot combines ultrasonic obstacle avoidance and infrared line tracking technologies to demonstrate real-world robotics principles in a simple and creative way.

Built on a durable laser-cut wooden chassis, the car includes two high-quality DC motors for smooth driving and a free-rotating caster wheel for balance. The wooden structure provides stability while allowing easy customization for experiments and classroom demonstrations. The car features two infrared sensors at the front for detecting black-and-white contrasts and following predefined paths, while the ultrasonic distance sensor enables automatic obstacle detection and avoidance.

Powered by a 6V AA battery pack, the system integrates reverse-polarity protection and stable current regulation, ensuring safe classroom use. The dual motor driver module (L298N) provides PWM-based speed and direction control, helping students understand motor driving principles, power management, and circuit design.

This kit supports multiple programming environments such as Arduino IDE, Mixly, and Scratch, offering both text-based and graphical coding experiences. Beginners can drag and drop logic blocks to create movement commands, while advanced users can experiment with conditional logic, sensor calibration, and algorithm optimization.

Ideal for STEM education, the robot teaches fundamental engineering concepts including electronic control, feedback loops, automation, and problem-solving. It’s perfect for science fairs, classroom projects, or self-paced robotics learning at home. Students learn how hardware and software interact — from signal sensing and decision-making to motion execution — forming a complete introduction to mechatronics and robotics.

The modular design makes assembly quick and intuitive, with labeled connectors for each component. This ensures safe, error-free wiring and repeatable classroom use. The open-source structure allows expansion with modules such as Bluetooth, Wi-Fi, and additional sensors, extending learning beyond basic robotics into IoT and AI-based control systems.

This compact and affordable DIY robot embodies the spirit of STEM innovation, encouraging curiosity, creativity, and critical thinking through every experiment

Ultrasonic Obstacle Avoidance System
The ultrasonic sensor uses sound waves to measure distance and prevent collisions. By calculating reflection times, the robot can automatically stop, turn, or reverse to avoid objects. Students learn about sensor data processing, automation logic, and reactive control — key principles in autonomous robotics and smart navigation systems.

Infrared Line Tracking Mechanism
Dual infrared sensors detect contrast between black and white surfaces to follow predefined paths. This module helps students understand analog signal interpretation, sensor calibration, and control loops, forming the foundation of robotics vision and navigation algorithms.

Arduino-Compatible Programming Environment
The kit supports both visual and text-based programming through Arduino IDE, Scratch, and Mixly. Students can write simple motion codes or develop advanced functions like obstacle detection, path optimization, and remote operation, linking coding logic to physical robot behavior.

Safe and Modular Engineering Design
The laser-cut wooden chassis offers durability and reusability while remaining lightweight. All modules are connected through labeled sockets for easy assembly. The 6V power system ensures safe classroom operation, and the rubber wheels provide strong grip for stable motion on multiple surfaces.

STEM Educational Value and Expansion
Combining mechanics, electronics, and coding, this kit enhances problem-solving and logical thinking skills. It encourages creativity through project-based learning, allowing users to extend functionality with Bluetooth and other modules for IoT experiments. Perfect for schools, robotics clubs, and makerspaces.
