Obstacle Avoidance Robot Car Kit | Wooden DIY STEM Chassis with Ultrasonic Sensor & Infrared Line Tracking | Arduino-Compatible Educational Smart Car for Coding, Electronics & Autonomous Navigation Learning | Easy Assembly for Students & Makers

This DIY wooden obstacle avoidance robot car kit is an ideal hands-on STEM learning tool that combines mechanical structure, electronics, and coding into a single interactive project. Designed with a lightweight laser-cut wooden chassis, the robot features two precision DC gear motors for smooth motion and an ultrasonic sensor for accurate distance detection. It detects objects ahead, measures distance, and automatically changes direction to avoid collisions — demonstrating the core principle of autonomous navigation.

The kit is fully Arduino-compatible and open-source, allowing students to modify the code freely and experiment with algorithms such as PID control or randomized path navigation. By writing simple C/C++ programs and uploading them through USB, learners grasp essential concepts like loop execution, sensor input reading, and motor PWM output. This combination of coding and real-world motion enhances problem-solving and logic skills in an engaging way.

The ultrasonic HC-SR04 sensor detects objects from 2 cm to 4 m with a narrow 15-degree beam, providing reliable data even in noisy environments. When the robot approaches an obstacle, it instantly reverses and rotates to find a clear path — simulating real AI behaviors. Infrared modules can be added to enable line-tracking or edge-detection functions. All electronic connections use color-coded wires and plug-and-play headers for easy assembly without soldering.

Built with sturdy plywood and brass pillars, the chassis balances strength and aesthetic clarity, helping students visually understand each electronic component and how it works within the system. The kit includes a battery holder, control board, ultrasonic sensor, motors, wheels, and mounting screws — everything needed to build a working robot car. Because of its open-source design, it can also integrate additional sensors such as temperature, Bluetooth, or Wi-Fi modules for remote control and data collection.

Educationally, the robot supports science classes, robotics clubs, and engineering labs to teach students about automation, sensor fusion, and embedded systems. It is ideal for demonstrating core concepts like feedback loops, distance measurement, and motor speed control. The project encourages creativity and innovation, offering learners the chance to design new behaviors or challenge friends in robot competitions.

This robot car kit serves as an excellent bridge between theory and practice for students, teachers, and hobbyists who want to learn robot design and programming from the ground up. It is a fun, interactive, and safe gateway into the world of STEM education and AI-driven robotics.
