Bot Part Factory

Bot Part Factory is a production building that manufactures the modular components required to assemble bots. It occupies a 3x3 grid of flat surface and offers three distinct recipes that produce Bot limb, Bot head, or Bot chassis. The building was introduced in Update 2 and was originally named Golem Part Factory; it was renamed to Bot Part Factory in Update 3.

Each recipe in the Bot Part Factory uses the same amount of work time but yields different quantities: in the same number of work hours the factory produces either four Bot Limbs, one Bot head, or one Bot Chassis. A single factory cannot work on more than one recipe at a time, so each factory must be assigned a specific part to produce. Because the relative output per work cycle differs between recipes, planning the distribution of recipes across multiple factories is important for maintaining steady bot assembly.

• The Bot Part Factory requires a 3x3 flat placement area.
• A factory can only construct one type of bot part at a time; it cannot split its production across recipes simultaneously.
• Production parity: three factories each set to a different part (one on Limbs, one on Heads, one on Chassis) produce exactly enough parts to supply two Bot Assemblers, assuming no interruptions.
• If production appears imbalanced relative to assembler demand, the most likely cause is a supply chain issue feeding the factories (raw materials, worker allocation, or transport), not an intrinsic production rate mismatch.
• Plan factory placement and part assignment to match the number of Bot Assemblers you intend to supply; scale factories in sets of three to evenly match assembler throughput.

The building’s historical name, Golem Part Factory, may still appear in older guides or assets from Update 2; official references after Update 3 use the Bot Part Factory name. The Chinese localization for the building is 机关人部件工厂.
