Arduino Compatible STEM Smart Robot Car Line Tracking Obstacle Avoidance IR Ultrasonic Programmable Nano Board Coding DIY Maker Robot Kit Plug & Play Robot Car for Kids Learning

This beginner-friendly Line-Following & Obstacle-Avoidance Robot Car Kit centers on a Nano-compatible controller with IR sensors, ultrasonic module and motor driver, providing a complete hands-on platform for robotics and coding education. Its modular, solder-free design enables quick assembly with clear diagrams, ideal for students and STEM instructors. The IR array detects line deviation to guide motion, while the ultrasonic module measures distance for obstacle avoidance from 2 to 400 cm. Combining both allows the car to perceive its environment and respond intelligently. By tuning PID parameters and observing motion stability, learners grasp feedback control theory through real experiments. Arduino IDE offers an open programming environment with C/C++ examples for line tracking, distance sensing, PWM speed control and logic operations. The system supports external expansion through I²C/UART interfaces for Bluetooth modules, OLED displays, IMU sensors and GPS receivers, encouraging creative projects and competitions. The chassis uses 3 mm acrylic and metal standoffs for durability, and differential drive with a universal support ball ensures smooth steering. The vehicle runs on standard 18650 battery power, allowing safe classroom operation without soldering or high-voltage components. Educators can design full STEM curricula: electronics basics, sensor principles, motion control, coding, debugging and integration. Each step yields measurable results in distance, response time and trajectory accuracy. The kit thus bridges theory and practice, inspiring logical reasoning and engineering curiosity. Certified under GCC, EN71, ASTM F963, CPSIA and IEC 62115, it meets educational safety standards. Recommended for students aged 8 and above under supervision, it’s ideal for schools, laboratories, competitions and home maker projects.
