We built this controller board for makers who care about precision, not patchwork fixes. Instead of spending hours tracing unstable signals and inconsistent power behavior, you start with a system designed to behave predictably.
The Techgeeks LFR Chassis is a modular ecosystem. From custom PCB trays to adjustable geometry, it adapts to your specific hardware stack. Whether you are running our ARC series or third-party sensors like Robojunkies, this frame ensures everything stays exactly where it belongs. Just plug in your motors, battery, PCB and sensor, and you have a competition-ready machine.
ACCESSORIES
PACKED COMPONENTs
Good things come in small packages, and inside of
this you will find everything you need to get your
line follower up and running. Both hardware and
software included.
PCB
◘ 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 / 11.1V). 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.
◘ Precision Line Tracking
◘ Smooth Corner Handling
◘ Real-Time Feedback System
SOFTWARE AND PROCESSING
◘ The Robot Controller PCB is built as an open, programmable platform, optimized for 16 MHz real-time embedded control applications, giving developers full control over system behavior. It supports custom firmware development with direct access to GPIO, PWM channels, ADC inputs, and hardware timers, enabling precise motor control, real-time sensor acquisition and deterministic control loop execution.
◘ Developers can implement PID control, sensor fusion, interrupt-driven routines, or state-machine architectures based on application needs. Stable power regulation and disciplined signal routing ensure consistent execution without electrical noise impacting processing accuracy.
◘ Dedicated PWM hardware ensures deterministic motor drive signals with minimal jitter, while the analog front-end supports stable, repeatable sensor sampling. Hardware-level timing resources allow precise loop scheduling and consistent sampling intervals, critical for real-time control accuracy
◘ Whether you are writing low-level register-based code or structured embedded frameworks, the Robot Controller Board provides a robust hardware foundation for real-time robotics applications and performance focused control systems.
