Exoskeleton — Factorio Production Calculator
Exoskeleton is crafted in the assembling machine in 10 seconds, producing 1 per craft from 10 × Processing unit, 30 × Electric engine unit, 20 × Steel plate. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 6 raw resources: iron ore, copper ore, petroleum gas, heavy oil, water, coal.

Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 40,260 |
| Copper ore | 29,400 |
| Petroleum gas | 28,500 |
| Heavy oil | 27,000 |
| Water | 10,500 |
| Coal | 1,200 |
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.

| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Processing unit × 10, Electric engine unit × 30, Steel plate × 20 |
What the whole chain needs
60 exoskeletons per minute pulls in 15 intermediate products, and the whole tree comes to 7,124 machines across 3 machine types, fed by 6 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 40,260 per minute, which is 44.73 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.

FAQ
How many assembling machines do I need for 60 exoskeletons per minute?
20 assembling machines. One at standard speed produces 3 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 exoskeleton take?
At 60/min the chain consumes 40,260 iron ore per minute, 29,400 copper ore per minute, 28,500 petroleum gas per minute and 3 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Is exoskeleton needed for science packs?
Not directly. It feeds Spidertron, and those in turn feed the science packs. Open the science pack page to see the demand that lands on this recipe.
