D2-1 Line Following Robot Kit

This product is sold unassembled and does not include batteries.

The D2-1 Line Follower Robot Kit is a Smart Line Follower Robot capable of automatically following a 16mm black line on a white surface. Using a red light source and sensitive optical sensors, it detects the reflection from the surface and precisely tracks the path. When the robot moves onto a white area, the sensor’s resistance changes, signaling that it has left the line. In response, the motors slow down or stop, and the red LED on the board turns off, allowing the robot to adjust its direction and return to the path.

Designed to operate at 3V, the kit features a compact PCB measuring 105×72×1.6 mm, making assembly straightforward. The chassis is made of fiberglass and includes two geared motors with durable wheels, providing stable control and accurate line tracking even on winding paths. This design classifies it as a Two-Motor Line Follower Robot Kit, offering both precision and power. Additionally, an optional encoder disk can be added for more accurate speed and distance measurements.

The Two-Motor Line Follower Robot is fully compatible with popular microcontrollers such as Arduino Uno and MEGA2560, making it ideal for educational, industrial, and research projects. Key applications include automated material transport in factories, hospitals, stores, and libraries, increasing efficiency and reducing human error. It is also suitable for obstacle avoidance projects, speed testing, and other robotics experiments. The 3D assembly map ensures that all components are easy to install.

Overall, the D2-1 Line Follower Robot Kit is an affordable and comprehensive tool for robotics enthusiasts and developers of intelligent systems. With optical sensors and precise engineering, it guarantees smooth and autonomous movement on complex paths. Its simple assembly and adjustable potentiometer for performance tuning make it an excellent choice for education and practical robotics projects.
