Smart Obstacle-Avoidance Car Kit 3-5 V Programmable DIY Robot | IR Line Tracking + Ultrasonic Distance Sensor + Motor Driver Module | STEM Educational Robotics Platform

The 2-Wheel Ultrasonic Obstacle Avoidance Smart Car Kit is an educational Arduino-based robotics platform designed for STEM learners and beginners. It combines a dual-motor drive system with ultrasonic and infrared sensors to teach automation principles through hands-on assembly and coding. Students can experiment with distance measurement, line tracking, and object detection to understand how robots perceive their environment and make decisions.
The robot car features a modular plug-and-play design with clearly labeled ports and wires that eliminate the need for soldering. It supports Arduino IDE programming as well as graphical coding software like Mind+, making it accessible for both young students and teachers. The kit includes ultrasonic sensor, IR tracking module, motor driver board, and chassis with durable wheels and battery holder. Each component is standardized for quick replacement and extension.
Learners can write simple code to make the robot follow lines, avoid obstacles, or navigate a maze, developing core skills in logic, electronics, and mechanical integration. The system provides a complete path from hardware assembly to software logic and algorithm testing. Its open-source structure encourages innovation and adaptation for classroom projects or competitions. This STEM kit is perfect for schools, workshops, and DIY enthusiasts interested in robotics education and engineering practice.

① Ultrasonic Sensor Obstacle Avoidance
Ultrasonic sensor enables accurate distance measurement and real-time obstacle detection. Students learn how sound waves are converted to digital signals for autonomous navigation. By coding threshold values and motion responses, learners experience core concepts of AI perception and feedback control.

② Infrared Line Tracking System
Infrared modules detect surface contrast to follow black lines on white backgrounds. This function introduces image processing logic at a foundational level, teaching how sensors guide robotic path planning and motor speed control.

③ Arduino Programmable STEM Platform
The kit supports Arduino IDE and block-based coding so students can progress from drag-and-drop to C++ syntax. This dual mode education develops logical reasoning, creativity, and hardware interaction skills.

④ Modular Solder-Free Assembly
All modules use XH2.54 ports with clear markings to simplify assembly and prevent wiring errors. No soldering is required, allowing fast setup and safe classroom use.

⑤ Complete Learning Experience for Beginners
Combining mechanics, electronics, and programming, this robot car kit offers a step-by-step curriculum that supports STEM teachers and students alike. It builds a foundation for advanced robotics and IoT projects.
