Learn fast, Break things, Build better. A competition-ready line follower designed for builders who want real control over hardware and code. Beyond running out of the box, MK-1 encourages experimentation. Users can modify code, adjust control parameters, add modules, and explore how changes in hardware and software affect real-world behavior.
Mark-1 was designed as a clean entry into competitive robotics without limiting how far you can take it. Whether you’re a beginner learning how sensors talk to code, or a competitor refining PID loops for race conditions, MK-1 scales with you. Arduino-based control, accessible electronics, and a modular layout make experimentation natural, not intimidating.

COMPREHENSIVE GUIDE
◘ The Mark 1 LFR is a compact, high performance line follower robot built around the ATmega328P microcontroller using the Arduino Nano platform operating at 16 MHz and 5V logic level.
◘ The robot is powered by a 2S LiPo battery (7.4V). A dual channel TB6612FNG motor driver enables efficient PWM based speed control of the high RPM DC N20 gear motors, providing smooth acceleration and sharp turning capability.
◘ It features an 8 Channel IR Sensor Array (ARC8) to detect contrast between black and white surface. It is equipped with 2 wheel drive system combined with high traction rubber wheels that provide stability.
◘ The frame is a lightweight 3D printed chassis (PLA+/PETG). With an approximate weight of 140–160 grams and compact dimensions, it is optimized for speed, agility and competition performance that make the Mark 1 both beginner friendly and competition ready.
SOFTWARE AND PROCESSING
◘ The Mark 1 LFR follows a structured control flow defined in setup() and loop(). On startup, the system waits for the left button press to initiate calibrate(). During calibration, the robot rotates using motorControl(100, -100) while recording minimum and maximum sensor readings.
◘ After pressing the right button, the robot enters run mode. In loop(), the readLine() function continuously reads and normalizes sensor data, identifying active sensors and determining whether the line is detected (onLine).
◘ If the line is present, linefollow() calculates positional error using weighted sensor inputs. A PID correction (using kp and kd) generates PIDvalue, which adjusts speedA and speedB around the defined robotSpeed. Speeds are constrained before being applied through motorControl().
◘ If the line is lost, recovery logic applies directional correction based on the last known error. This ensures stable tracking, smooth steering, and responsive real time control.
COLOR, MATTE
AND FINISH
Available in four color options, the robot features a precision 3D-printed matte chassis paired with high-traction rubber wheels and cleanly integrated components, delivering a cohesive, durable, and competition-ready finish.

Arduino line follower Robotics kit for Students, Builders, college students and more - India
The Mark 1 Line Follower Robot is a complete Arduino-based robotics kit designed specifically for students preparing for robotics competitions, engineering lab projects, and embedded systems learning. It features the ATmega328P microcontroller via Arduino Nano, an 8-channel analog reflectance IR sensor array (ARC8), a TB6612FNG dual-channel motor driver, two 6V 600 RPM D-shaft N20 gear motors, 30mm high-traction rubber wheels, and a lightweight 3D-printed PLA/PETG chassis — all powered by a 2S 7.4V LiPo battery with on-board 5V regulation and power decoupling. Available as an unassembled DIY kit or a pre-assembled ready-to-run bot, in four matte color options.
The Mark 1 LFR uses a PID (Proportional-Integral-Derivative) control algorithm for smooth, competition-grade line tracking. The firmware includes a calibration routine, weighted sensor error calculation, and real-time PID correction across both motor channels. Open-source code is available via the TechGeeks GitHub repository, along with a comprehensive build guide covering assembly, wiring, code upload, and tuning. Whether you're learning about embedded systems for the first time or optimizing for speed and accuracy at a robotics competition, Mark 1 is the platform built for that journey.
If you're searching for a line follower robot kit in India that goes beyond the standard 3-sensor beginner kits sold on Amazon or Flipkart — a kit that teaches real control theory, uses competition-standard components, and comes with proper documentation — the Mark 1 is your answer. It ships across India with free delivery on orders above ₹1999, and is used by students from IITs, NITs, VIT, SRM, Amrita, and hundreds of other colleges competing at Techfest, Robocon, Smart India Hackathon, and college-level tech fests nationwide.
The Mark 1 is TechGeeks' entry-level competition line follower robot kit, designed for engineering students, college makers, and first-time robotics competitors. Built around the Arduino Nano (ATmega328P, 16 MHz), it uses an 8-channel analog IR sensor array (ARC8) for precise line detection, a TB6612FNG dual motor driver for smooth PWM speed control, and 600 RPM N20 gear motors for responsive steering. The lightweight 3D printed PLA/PETG chassis weighs just 140–160 grams, making it nimble enough for competition tracks. It runs on a compact 2S 7.4V LiPo battery with on-board power decoupling and reverse voltage protection.
Who Is It For: Engineering students in their 1st–3rd year, robotics club members prepping for Techfest, Robocon, e-Yantra, or college tech fests, and any maker who wants to learn embedded systems hands-on rather than through tutorials alone.
Why Mark 1: Most entry-level robot kits in India use cheap BO motors, fixed sensor spacing, and basic analog comparators. Mark 1 uses a custom PCB controller (Blueprint 01), an 8-channel analog reflectance IR array with calibration routines, and a PID-based firmware with full source code — the same architecture used in competitive bots, just at an accessible entry price.
