Arduino-Compatible Bluetooth Smart Robot Kit | Infrared Line Tracking + Ultrasonic Avoidance | Supports C, Scratch & Mixly Coding | Ideal for STEM Classrooms, Competitions & Maker Labs

This Smart Bluetooth-Controlled Line-Tracking and Obstacle-Avoidance Robot Car Kit offers a comprehensive robotics learning experience that integrates motion control, environmental sensing, and wireless communication. Built for classrooms, STEM labs, and makerspaces, it allows students to understand how sensors, actuators, and algorithms interact in autonomous systems.

The robot’s four-wheel-drive chassis ensures strong traction and stable movement on a variety of surfaces. Each motor is driven by a PWM control signal from an Arduino-compatible mainboard, allowing smooth acceleration, turning, and braking. The front-mounted ultrasonic sensor detects obstacles in real time and guides the robot to change direction. Dual infrared sensors on the underside read black-white contrast to follow lines accurately, teaching students about feedback control and sensor fusion.

The system supports Bluetooth connectivity, enabling smartphone-based remote control through an intuitive mobile app. Students can switch between manual driving and autonomous navigation modes, explore data transmission principles, and even create custom control interfaces using Bluetooth serial communication.

The power system operates between 6–9V with built-in reverse-polarity and overload protection. Capacitive filtering stabilizes voltage under high motor load, ensuring consistent performance. All components connect via modular cables — no soldering required — simplifying classroom assembly and maintenance.

Software support includes C, Scratch, and Mixly coding environments, with ready-to-use project templates. Lessons progress from basic line following to advanced multi-sensor navigation, introducing students to control logic, loops, and conditional structures. Example programs demonstrate key topics like PWM motor speed control, servo-angle calibration, and Bluetooth serial command decoding.

The included educational guide contains 15 structured lessons and over 20 experiments:
