THE

ORIGINS

CAPABILITIES

& PERFORMANCE

Our team at Techgeeks realized the issue of accessibility. Makers have their electronics, MCUs, sensors, motors, but nothing to bridge it together. Thus the idea of a modular basic Line follower chassis arose. we measured and mastered every millimeter to perfect the dimensions and clearances. We understood exactly what you needed - a reliable, pretty and strong base for your line follower.

Whether you use our hardware or you are on your own, the basic LFR chassis will top up your performance.

Basic LFR Chassis – Modular 3D Printed Line Follower Frame

The TechGeeks Basic Line Follower Chassis is a precision 3D-printed robot frame engineered for N20-motor-based line follower robots used in Indian robotics competitions. Made from PLA+ or PETG for maximum strength-to-weight ratio and impact resistance, the chassis features in-built N20 motor mount slots (compatible with standard, high-RPM, and encoded N20 motors), an adjustable-length sensor arm for geometry optimization, and a snap-fit PCB tray system supporting the TechGeeks Blueprint 01 board, 6×5cm PCBs (standard for Robojunkies and custom builds), and 7×5cm large-format PCBs. Weighing just ~45 grams including two 30mm × 20mm high-traction rubber wheels, it sits well within the weight budget of any competition. Sensor compatibility is a defining feature of the Basic LFR Chassis. It natively supports TechGeeks ARC8 and ARC16 arrays, Robojunkies 5/7/8/16 channel arrays, QTR-8 RED sensors, and a universal mounting hole pattern for any other IR sensor array. The adjustable sensor-to-wheel geometry allows fine-tuning of the line detection point, which directly impacts PID performance at speed. The result is a chassis that works whether you're running your first PID experiment or optimizing for a sub-second lap at a tech fest. If you're looking for a line follower robot chassis in India that works with N20 motors, accommodates standard competition PCBs, and ships with proper hardware for assembly — the TechGeeks Basic LFR Chassis is your answer. Available in four matte color options with free delivery across India on orders above ₹1999. Used by students building robots for Techfest IIT Bombay, Robocon, e-Yantra, Smart India Hackathon, and hundreds of college tech fests with line follower and maze solver competitions.

The TechGeeks Basic LFR Chassis is a modular 3D printed line follower robot frame, designed to eliminate the structural guesswork so makers can focus on electronics and code. Made from high-quality PLA+ or PETG with quality-checked dimensional tolerances, it features in-built precision N20 motor mounts (compatible with all D-shaft and encoded N20 variants), an adjustable sensor arm for geometry tuning, and a snap-fit PCB tray system in three size configurations: TechGeeks PCB, 6×5cm (Robojunkies/custom), and 7×5cm (large custom PCBs). Who Is It For: Students and makers who have their own electronics — Arduino, motor driver, sensor, motors — but need a proper structural frame to bring it together. Also perfect for anyone upgrading from a wooden plank or acrylic sheet chassis to a purpose-designed, competition-dimensioned robot frame. Compatible with ARC8, ARC16 (TechGeeks), Robojunkies 5/7/8/16 channel arrays, QTR-8 RED sensor, and a universal mount for any other sensor. Why This Chassis: Most chassis available in India are either a flat acrylic plate (no motor alignment), a BO motor chassis (wrong motor type), or a generic 3-wheel design with no competition relevance. This chassis is built specifically for the N20 + sensor array architecture used in every serious line follower competition in India. The adjustable length and modular tray system mean it adapts to your specific build, not the other way around.
