DIY Intelligent Line-Tracking Robot Car Kit

• Minimum Age: 14+
• Difficulty Level: 3
• Estimated Build Time: 3–5 hours

Why This Project Belongs on Your Workbench:

Step into the world of robotics and electronic logic. The DIY Intelligent Line-Tracking Robot Car Kit combines hands-on assembly with fundamental engineering principles, giving you a front-row seat to how modern technology actually works.

Technical Specifications

• Product Type: Intelligent Line-Tracking Robot Car (D2-5)
• Project Category: Electronic Soldering & Robotics Module
• Package Format: DIP (Dual In-line Package) — Ideal for beginner to intermediate through-hole soldering.
• Customization: Fully adjustable sensor logic
• Safety Rating: 100% Non-toxic / No high-concern chemicals
• Hardware Intelligence: Learn how infrared sensors actually "see." The car uses emitters and phototransistors to differentiate between the track and the floor, adjusting its motors in real-time to stay on course.
• The "Mechatronics" Experience: It's not just a circuit; it's a vehicle. You'll assemble the gearbox, wheels, and chassis, giving you a hands-on crash course in how electronics and mechanics work together.
• Master the DIP Package: This kit uses through-hole (DIP) components. They are the gold standard for learning because they're easy to handle but result in a professional-grade, functional robot.
• The Ultimate Teaching Toy: Perfect for school labs or home experiments. It provides a tangible, moving result that proves your soldering skills are on point.
• Model: D2-5 Smart Tracking Car
• Control Logic: Pure hardware circuit (No coding required)
• Sensors: Dual Infrared Reflection Sensors
• Chassis Material: High-durability PCB (Doubles as the car's structural frame)
• Drive System: Dual Motor with independent wheel control for precision turning.
• Soldering Level: Beginner to Intermediate. It's the perfect step up from the LED Watch or the LM317 kit.
• Calibration is Key: Once you've finished soldering, you can "tune" the sensitivity of the sensors using the onboard potentiometers to ensure your car stays perfectly on the line even at higher speeds.
• Power Note: You'll need a standard battery power source (typically 2x AA) to get this moving. Batteries aren't included, so make sure your lab is stocked!
