How to Prepare for Your First Line Follower Competition in 15 Days
How to Prepare for Your First Line Follower Competition in 15 Days
Most first-time competitors spend the first week watching tutorials and the last 48 hours cramming the build, the wiring, and the tune into one panicked stretch. This is the order to actually do it in instead — learn, build, calibrate, tune, practice — so nothing is still unfinished the morning of. A day-by-day, 15-day plan for anyone walking into their first Techfest, Robocon-style, or college LFR event with a deadline.

What Is Active Downforce? The F1 Physics Powering Our Fastest Line-Follower Robot
What Is Active Downforce? The F1 Physics Powering Our Fastest Line-Follower Robot
F1 just retired DRS after fifteen seasons and replaced it with a fully active aero system — wings that reshape themselves every lap depending on whether the car is cornering or on a straight. Techgeeks built a version of "active downforce" into our line follower robots, just using suction instead of wings. Here's the physics behind both, and why it's the real reason our Suction Chassis robots hold corners other robots can't.

COMPARISON & USECASE GUIDE
Motor Drivers 101: TB6612FNG vs L298N vs a Dedicated ESC
Motor Drivers 101: TB6612FNG vs L298N vs a Dedicated ESC
Not every motor driver does the same job, even though most beginner tutorials treat them as interchangeable. This guide breaks down how the TB6612FNG and L298N actually differ under the hood, and why a suction impeller needs a completely different kind of controller than your drive motors do.

why choose us
brand
At Techgeeks, we believe that great innovation starts with right people and reliable tools. We are committed to delivering the highest quality hardware to ensure nothing stands between you and your creation.
Thank you for choosing us to fuel your curiosity. Cheers to building the future.
TechGeeks is building India's most engaged robotics hardware community — a space for engineering students, makers, and competition robotics teams who believe in building over talking. Our community connects on Instagram (@techgeeeks), WhatsApp, Discord, LinkedIn, and GitHub, sharing build logs, competition results, code repositories, and hardware experiments. Whether you're tuning your first PID loop, preparing for Techfest IIT Bombay, or building a maze solver for Robocon, the TechGeeks community is where your peers are. Our product resources hub provides direct links to GitHub source code, build guides, product manuals, and technical documentation for every TechGeeks product — Mark 1 LFR, Mark 2 Advanced Suction LFR, ARC8 and ARC16 sensor arrays, Blueprint 01 controller board, and all chassis and components. Everything is open-source and designed to be learnable — because zero gatekeeping is our core philosophy. The Open Sauce blog documents our builds, engineering decisions, and component deep-dives in the same no-fluff style as the products themselves. TechGeeks events, workshops, and meetups bring the community offline — joining competition teams at college tech fests across Delhi, Bangalore, Mumbai, Chennai, and beyond. We post event coverage, moments, and archives here as they happen. Follow @techgeeeks on Instagram for the fastest updates, or join the WhatsApp community to connect with other builders directly.
This is the TechGeeks community hub — where Indian makers, robotics builders, and engineering students come together. Follow our latest builds and releases on Instagram, access product documentation and GitHub repos, explore blogs and tutorials, and stay updated on events, meetups, and tech fests where TechGeeks hardware will be competing.
