Arduino Smart Robot Car Kit | STEM 4WD Educational Robot for Coding & Robotics | Ultrasonic Obstacle Avoidance & Infrared Line Tracking | DIY Programmable Kit with Servo Steering, PWM Motor, Bluetooth/Wi-Fi Expansion for STEM Projects

Arduino Smart Robot Car Kit introduces students to the principles of STEM robotics, combining mechanical engineering, sensor technology, and programming into a single interactive learning system. The kit features ultrasonic obstacle avoidance and infrared line tracking, enabling real-time navigation through sensor feedback and logical control algorithms.

Built on a 4WD acrylic chassis, this robot integrates four high-torque DC motors, dual infrared sensors for line detection, and a servo-mounted ultrasonic module for dynamic distance measurement. The ultrasonic sensor continuously scans the surrounding environment, allowing the robot to detect and avoid obstacles intelligently. The infrared sensors identify line contrast, helping the car follow paths precisely.

Powered by a 6–9V DC power system, the robot includes built-in reverse polarity and overcurrent protection, ensuring safe operation in classrooms. Capacitive filtering maintains voltage stability, while PWM control offers smooth speed adjustment and directional control. The modular design eliminates soldering — all components connect via labeled ports, simplifying assembly and reducing classroom setup time.

The Arduino-compatible controller allows students to write and upload code easily via Arduino IDE, Scratch, or Mixly visual interfaces. Example projects guide learners through motion control, ultrasonic distance measurement, servo positioning, and autonomous navigation. The kit includes a structured learning curriculum that builds from basic wiring to advanced motion algorithms.

The educational pathway covers:

Understanding motor control and PWM concepts.

Assembling the 4WD chassis and wiring sensors.

Measuring distance using ultrasonic modules.

Detecting and following lines with infrared sensors.

Integrating both systems for obstacle-aware navigation.

Implementing servo scanning and rotation logic.

Bluetooth control via smartphone and serial communication.

Extending with Wi-Fi for IoT connectivity and remote programming.

Final project: designing a fully autonomous navigation robot.

This educational robot platform helps students understand real-world robotics systems through project-based learning. It fosters skills in algorithmic thinking, debugging, and teamwork. Teachers can use it to demonstrate feedback systems, automation logic, and mechanical-electrical integration.

Durable acrylic construction ensures reusability in classrooms and maker labs. Its modular architecture allows for easy upgrades with additional sensors, cameras, or wireless modules. The ZYC0063 robot car is a powerful bridge between theoretical knowledge and practical robotics education — a complete STEM experience in one accessible platform.
