This tracking car is equipped with a photosensitive resistor system that detects changes in surface reflectivity to guide its movement with precision. By measuring the resistance of the photoresistor, the car can determine whether it is driving over a white or black surface, ensuring accurate path tracking without manual intervention. Key Features and Benefits: Automatic path detection using a builtin photosensitive resistor for reliable navigation. Optimized for white background surfaces with a 16 mm wide black runway for consistent tracking performance. Capable of maintaining course regardless of track curves, thanks to its responsive reflectivity sensing system. Uses red light for surface detection, enhancing contrast between white and black surfaces for accuracy. Performance and Compatibility: Designed for environments with a clear black track on a white field. Suitable for a variety of track layouts including straight paths, curves, and complex patterns. Functions effectively in different indoor lighting conditions for dependable results. Compact design suitable for educational kits, robotics projects, and smallscale automation demonstrations. Practical Applications: 1. Robotics education – ideal for teaching principles of sensorbased navigation and automated guidance systems. 2. Hobby projects – for enthusiasts building and testing autonomous vehicles on custom track designs. 3. Demonstrations and exhibitions – effective for showcasing automatic tracking technology in classrooms, labs, or trade shows. Specifications: Photoresistorbased detection system for reflectivity measurement. Standard track design requirement: white background field with a 16 mm black runway. Automated navigation system capable of following curves and bends without manual control. Red light detection for enhanced contrast and accuracy. This tracking car delivers dependable autonomous navigation and is well suited for both educational and demonstration purposes while maintaining reliable performance across various track shapes and layouts.
