OPEN SAUCE

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.

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.

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.

Part 1 covered everything inside India. This one covers what's next: FRC, VEX, RoboCup, underwater robotics, Mars rovers in the Utah desert, and the rest of the world's major robotics competitions, including the ones Indian college teams are already quietly competing in, and sometimes winning.

Everyone in your robotics club WhatsApp group has an opinion on which competition to enter first, and almost none of them agree. This is Part 1 of a two-part guide to every major robotics competition Indian students can enter, sorted by skill level, format, and cost, starting with everything that happens inside India: Techfest, DD Robocon, e-Yantra, the school-age pipeline, and a few homegrown competitions most students never hear about until it's almost too late.
