The term Blessed Autocimulacra refers to an extensive set of automatic repair systems used by the vehicles and combat walkers of the Adeptus Mechanicus. These self-repair systems can range from self-healing alloys sourced from irreplaceable relic-stockpiles, to on-board Servitor-simulacrum used to shore up breaches and re-route severed fuel and circuit lines while chanting the Rites of Revivification.

The same automated repair systems are present in the hellforged vehicles and combat walkers of the Dark Mechanicum, and are known as Infernal Autocimulacra.
