Smart Robot Car Kit for STEM Education | Arduino-Compatible Obstacle Avoidance & Line Tracking Robot with Ultrasonic and Infrared Sensors, Dual DC Motors, UNO Controller & L298N Driver | DIY Coding Robot for Kids, Makers & Classroom Projects

Smart Robot Car Kit for STEM Education is an Arduino-based learning platform that introduces students and makers to core robotics concepts through interactive assembly and coding. Built on the UNO R3 microcontroller and L298N dual-motor driver, it teaches the principles of automation, sensors and control logic. The kit features a pair of TT DC motors, an ultrasonic sensor for obstacle avoidance and a three-channel infrared line-tracking module for route following, allowing learners to program real-world decision-making behaviors such as turning, stopping and speed adjustment.

Each module connects via plug-and-play terminal cables — no soldering required — enabling students to focus on logic rather than hardware assembly. The clear acrylic chassis exposes the motor mounts, sensor alignment and wiring, offering an intuitive view of how mechanical and electronic systems interact. Through Arduino IDE or graphical interfaces such as Mixly, users learn loop structures, PWM motor control, and sensor-based conditional logic. By observing the robot’s reaction to line contrast and distance feedback, they grasp fundamental STEM topics — data acquisition, signal processing and closed-loop control.

The Smart Robot Car Kit provides a hands-on bridge between physics and coding. Students experiment with voltage supply (7–12 V), learn current distribution for dual motors, and measure speed in RPM relative to input voltage. The ultrasonic sensor (HC-SR04) detects objects from 2 to 400 cm within a 15° cone, while infrared modules read surface contrast to maintain a path. Teachers can assign tasks like maze navigation, auto-parking or precision line racing to strengthen problem-solving and teamwork skills. All open-source Arduino libraries are included, simplifying expansion into Bluetooth, Wi-Fi or IoT projects.

The robust acrylic base and dual-wheel drive offer durability and smooth motion on flat surfaces such as classroom desks or lab benches. The car’s compact design (approx. 15 × 10 cm) and low-weight frame make it ideal for school labs and home learning. Each kit comes with motor mounts, screws, sensor brackets, and a step-by-step manual detailing wiring and code examples — ideal for first-time builders and instructors alike.

Beyond technical skills, the project inspires curiosity in automation and engineering. Learners see how inputs from sensors translate into real-time motion through algorithmic decisions, building a foundation for future AI and robotics education. The kit complies with CE and RoHS safety standards and uses eco-friendly materials suitable for classroom use. Its reusable modules encourage experimentation and reduce electronic waste.

Perfect for STEM competitions, robot workshops and DIY makerspaces, this Smart Robot Car Kit offers an engaging way to learn circuit design, mechanics and C programming in one educational tool. Whether you are a teacher looking to demonstrate automation, a student building your first robot, or a parent supporting STEM learning at home, this kit turns theory into motion — bringing science to life in every lesson.
