Roboport — Factorio Production Calculator
Roboport is crafted in the assembling machine in 5 seconds, producing 1 per craft from 45 × Steel plate, 45 × Iron gear wheel, 45 × Advanced circuit. At 60 per minute you need 10 assembling machines, and the chain behind it draws on 4 raw resources: petroleum gas, iron ore, copper ore, coal.
Production chain for 60 Roboport / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 27,000 | 225 | Assembling machine |
| Iron plate | 24,300 | 1,296 | Furnace |
| Copper plate | 13,500 | 720 | Furnace |
| Electronic circuit | 5,400 | 90 | Assembling machine |
| Plastic bar | 5,400 | 45 | Chemical plant |
| Steel plate | 2,700 | 720 | Furnace |
| Iron gear wheel | 2,700 | 45 | Assembling machine |
| Advanced circuit | 2,700 | 540 | Assembling machine |
| Roboport | 60 | 10 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Petroleum gas | 54,000 |
| Iron ore | 24,300 |
| Copper ore | 13,500 |
| Coal | 2,700 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Roboport recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 5 s | 1 | Steel plate × 45, Iron gear wheel × 45, Advanced circuit × 45 |
What the whole chain needs
60 roboports per minute pulls in 8 intermediate products, and the whole tree comes to 3,691 machines across 3 machine types, fed by 4 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 54,000 per minute, which is 60 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses roboport
No base-game recipe consumes roboport — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What roboport is made from
- Steel plate — 45 per craft
- Iron gear wheel — 45 per craft
- Advanced circuit — 45 per craft
FAQ
How many assembling machines do I need for 60 roboports per minute?
10 assembling machines. One at standard speed produces 6 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does roboport take?
At 60/min the chain consumes 54,000 petroleum gas per minute, 24,300 iron ore per minute, 13,500 copper ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
