I remember BuildCraft Builder eating blueprints and assembling structures, and Ancient Warfare having a similar block as well. None of them are drones though. The only one with drones is OpenComputers with its programmable robots, at least to my knowledge. There is a program that converts .schematic files to blueprints that can be given to robots for automatic construction. A more gamey implementation (besides Factorio-inspired modpacks that came later) is Golem Factory. It's an old and extremely underrated map-based pack where you automate Thaumcraft golems on a factory, deliver various shipments to earn quicksilver (money), and purchase upgrades & new machines to access higher speeds & higher grade shipments. Each shipment has a little story to go with it, which is very cute.
