Construction robot — Factorio Production Calculator
Construction robot is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 1 × Flying robot frame, 2 × Electronic circuit. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 5 raw resources: water, petroleum gas, iron ore, heavy oil, copper ore.

Raw materials
| Resource | Per minute |
|---|---|
| Water | 8,400 |
| Petroleum gas | 3,600 |
| Iron ore | 1,428 |
| Heavy oil | 900 |
| Copper ore | 750 |
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.
Construction robot recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Flying robot frame × 1, Electronic circuit × 2 |
What the whole chain needs
60 construction robots per minute pulls in 14 intermediate products, and the whole tree comes to 262 machines across 3 machine types, fed by 5 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 8,400 per minute, which is 9.33 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 construction robot
No base-game recipe consumes construction robot — 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 construction robot is made from
- Flying robot frame — 1 per craft
- Electronic circuit — 2 per craft
FAQ
How many assembling machines do I need for 60 construction robots per minute?
1 assembling machine. One at standard speed produces 60 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 construction robot take?
At 60/min the chain consumes 8,400 water per minute, 3,600 petroleum gas per minute, 1,428 iron ore per minute and 2 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
