Supports wireless Bluetooth control via compatible mobile phones or other Bluetooth-enabled devices, enabling convenient, real-time operation and flexible movement control. Uses a classic C51 microcontroller as the main control unit, making it suitable for learning embedded C programming, I/O control, and basic algorithm design. Built-in gravity/tilt sensing module allows the car to respond to changes in orientation, providing an intuitive way to experience sensor-based control. Equipped with line-following sensors that allow the car to automatically follow black or white tracks on the ground, ideal for path-following experiments and competitions. Integrated obstacle detection sensors help the car automatically identify and avoid obstacles, improving safety and enhancing interactive play and learning.
