DIY D2-5 Intelligent Tracing Car Kit (without battery)

The DIY D2-5 Intelligent Tracking Line Car Kit is one of the most widely used educational kits in schools and STEM programs, offering students a hands-on introduction to the world of electronics and robotics. This kit is specially designed to help learners understand the fundamentals of mechanical structure, basic electronic components, sensor technology, and automatic control—all through a fun and engaging assembly project.

Ideal for beginners, the D2-5 kit includes all the necessary components required to build a fully functional line-following robot car. The project encourages students to develop key technical skills such as circuit assembly, soldering, and troubleshooting. It features IR sensors that detect and follow a black line on a white surface, simulating basic automated behavior similar to what is used in industrial robotics and automation systems.

By assembling this kit, students gain practical experience with essential components such as resistors, capacitors, LEDs, transistors, motors, and integrated circuits. They also learn how these components interact to control the movement of the car based on sensor input—bringing theory to life in a tangible, interactive way.

The DIY D2-5 Tracking Car Kit not only enhances students’ technical understanding but also builds soft skills such as problem-solving, critical thinking, and patience. It is widely adopted in classroom environments, science exhibitions, and robotics workshops due to its simplicity, reliability, and educational value.

Whether used for school assignments or independent exploration, this kit is a great gateway to the exciting world of electronics and robotics, making learning both accessible and enjoyable.

Features

• There is a 16 mm wide black runway in the white field. This tracking car can drive along the black runway automatically.
• No matter how the runway is bent, the car can be driven automatically. We all know that the reflectivity is different when the light source to the white objects and black objects. Here we use red light source.
• The light is reflected through the ground to the photoresistor. By detecting the resistance of the photosensitive resistor can determine whether the car is driving in the white area.
• If the detection is black runway, then the car to change the direction of driving and motor will slow down or even stop and Red LED OFF on PCB front side.  Drive the car in the opposite direction so that the car is always running along the runway.
