Most will eventually go into a state of mindlock, babbling incoherent nonsense as the servitor tries to assert some form of control over its functions. The altered and fragmented brain of a servitor functions poorly unless constantly supervised.

Their brains are programmed to perform only the task they were designed for, whether that be maintenance, construction, or even warfare. Servitors are generally mindless, semi-organic robots, possessing only the most basic of instincts, though some are fully capable of speech if such functions and knowledge are programmed into them. Once lobotomised and 'improved' through the process of painful operations, even criminals and Heretics are granted one last chance to serve the Imperium. These unfortunate criminals will be sentenced to Servitude Imperpituis by the Arbitrators or Judges of the Adeptus Arbites and will be handed over to the Mechanicus' Tech-priests to be mind-wiped, reprogrammed, and cybernetically-enhanced to serve some specific, rudimentary function. These servitors were usually criminals who fell afoul of Imperial Law, particularly a person who has offended or damaged the Adeptus Mechanicus in some fashion. While many of these programmable cybernetic slaves are genetically-engineered, vat-grown, sub-Human clones or replicae created by the Adeptus Mechanicus from Human genomes who have their bionic implants installed after 'birth', others were once truly Human. They believe such artificial general intelligences to be the embodiments of blasphemy against the Omnissiah. Servitors were created due to the strict prohibitions against the development or use of machine intelligences according to the tenets of the Cult Mechanicus, whose tech-priests deeply fear the creation of Silica Animus. A servitor is the catch-all term applied to a wide class of mindless, cybernetic drones created from a fusion of Human flesh and robotic technology that are used to carry out simple, manual tasks across the Imperium of Man.
