Mechanoid hive

Mechanoids - Autonomous intelligent robots built for domestic, industrial or military purposes. Only available to advanced cultures because such complex AI is needed to control them.
— RimWorld Universe Quick Primer

Mechanoids are deadly autonomously intelligent robots.

Summary

Mechanoids are machines. They do not eat and are immune to toxic fallout and temperature extremes, despite having a Comfortable Temperature range. Enemy mechanoids have no needs at all. As machines, they are vulnerable to EMP attacks, though will "Adapt" for 2,200 ticks (36.67 secs) (regardless of source), making them immune to all further EMP strikes.

Mechanoid Hive

Main article: Mechanoid Hive

Hostile mechanoids are part of a Mechanoid Hive. They can be found sealed in ancient ruins in all biomes, which spawn inside mountains or outside on the landscape. They may also raid the player's base through events and can also be found in most poison ships and psychic ships. They may sometimes appear dormant in Ancient Complex and guarding any relic with Ideology DLC.

Allied Mechanoids

In the Biotech DLC, more mechanoid types are added, and mechanoids can be gestated by your colony. A mechanitor with enough bandwidth is required to keep them from going feral. These gestated variants require power and have to be recharged, which creates Pollution.

Mechanoid Types

Mechanoid forces are specialized by their unit types, with each unit performing a single role. Basics summaries are available here, see the individual pages for further details and analysis.

Trivia

Although all mechanoid-only weapons are 'Spacer' in terms of tech level; the hidden mechanoid faction itself is actually 'Ultra' tech level - one above 'Spacer', and the second highest tech level in the game, below 'Transcendent'.
