Description
The D2-1 2WD Line Following Robot Kit is an educational DIY robotics kit designed to build a simple analog line-following robot. The robot uses LDRs (Light Dependent Resistors) in combination with an LM393 comparator IC to detect contrast between a line and the surface, allowing it to automatically follow a predefined path. This kit does not require any programming, making it ideal for beginners learning the fundamentals of robotics, electronics, and sensor-based control systems.
