Smart Obstacle-Avoidance Car Kit 3-5 V Programmable DIY Robot

This 2-Wheel Ultrasonic Obstacle Avoidance Smart Robot Car Kit is a compact and beginner-friendly Arduino-based STEM robotics platform designed to teach automation, sensor integration, and programming logic through hands-on learning. Built with a dual-motor differential drive system, it combines ultrasonic distance sensing and infrared line tracking to demonstrate how robots perceive their environment and make intelligent decisions.

The robot uses an ultrasonic sensor to measure distance in real time, allowing it to detect obstacles and adjust its movement automatically. At the same time, the infrared tracking module detects contrast between black and white surfaces, enabling accurate path following. This dual-sensor system introduces students to sensor fusion, feedback control, and real-time decision-making, which are essential concepts in modern robotics.

Designed with a plug-and-play modular structure, all components connect through clearly labeled ports without soldering, ensuring safe and efficient assembly for classroom environments. The kit supports both Arduino IDE programming (C/C++) and graphical coding platforms such as Mind+, allowing learners of different levels to engage with robotics in an accessible way.

Students can build projects such as line-following robots, obstacle-avoidance vehicles, and simple autonomous navigation systems, gaining practical experience in electronics, mechanical assembly, and algorithm development. The open-source architecture allows further expansion with Bluetooth or Wi-Fi modules, encouraging creativity and innovation.

Ideal for schools, STEM workshops, and beginner robotics enthusiasts, this kit provides a complete learning pathway from basic circuit assembly to intelligent robotic control, bridging theory and real-world application.

Power Supply Note:
The kit requires 2 × 18650 3.7V batteries (not included), allowing users to select battery capacity according to their project needs. Instructions and learning resources are available via manual download link and QR code.
