Why the PCB Is the Chassis: Inside the Techgeeks Spirit Design
Why the PCB Is the Chassis: Inside the Techgeeks Spirit Design
The Spirit skips the separate frame entirely and lets one PCB carry the motors, the impeller, and every electronic component. Here's the engineering logic behind that decision, and the stiffness-for-modularity trade it makes along the way.

BUYING GUIDE
Kit or Pre-Assembled Bot? The Real Trade-off Nobody Explains
Kit or Pre-Assembled Bot? The Real Trade-off Nobody Explains
The site calls it "unassembled kit" versus "premade bot." What that choice really costs you is time, skill, and how well you know your own robot when it breaks. Decide by your deadline, not by which box looks easier.

Arduino Nano vs Uno vs ESP32: Which Board Should Beginners Use?
Arduino Nano vs Uno vs ESP32: Which Board Should Beginners Use?
Three boards show up in every beginner search, and most guides never say why only one fits inside an actual robot chassis. This breaks down pin count, logic voltage and size, the details that decide it for a line follower.

why choose us

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.
