Strip an industrial robot to its bones and you find seven technologies. India has most of them in hand — the castings, the controller, the software. The one it lacks is a strange gear called the harmonic drive, which lets the arm bend with perfect repeatability, and which a handful of makers — mostly Japanese — supply to the entire planet. That single gap keeps the whole machine imported. IndiaBUILD, a new Swarajya project, exists to map exactly these gaps — all of them. WHAT IT IS A living wiki of the hard technology India imports but could build. 18 sectors. 2,500+ capabilities mapped. 4,000+ sourced claims — growing daily. Every capability graded on an honest six-step ladder, from none to competitive — and built-under-licence sits on a lower rung than owned-design. Every claim tied to a checked source: AI-researched, machine-verified, human-published. HOW IT THINKS Products sit on trees of capabilities — a robot arm on seven, a jet on hundreds. Dependencies are drawn as edges: master one part and you unlock many machines (one precision ballscrew feeds CNC tools, robots and chip fabs alike). Builders are tracked with their claimed stage and our assessed stage, side by side. Statuses carry dates, so the map records movement. ALREADY ON THE MAP Why every MRI in India runs on 100% imported liquid helium. The three materials that decide chip sovereignty — polishing slurry, substrate film, photoresist — none made here. The Ukrainian plant that supplied Indian train wheels, until the war stopped it in 2022. The solar chain: modules assembled at world scale, every wafer beneath them imported. You cannot build what you have not named. The map names 2,500. Each name has a page, and each page shows its sources.
