Auto - Doc An Auto - Doc ( abbreviation of " Automatic Doctor " ) is a miracle of pre - War medical technology - a device capable of performing even the most complex medical procedures without qualified medical personnel . Even for a talented physician , these are invaluable aids . Early models were retroactively upgraded with new software and functionality introduced in later Auto - Docs before the Great War and as such , even Mark I devices are commonly able to perform complex surgeries just as well as the Mark IX and Sink models . Typically , Auto - Doc functionality includes regenerating health , restoring crippled limbs and performing surgeries , as well as being capable of implementing implants that enhance both physical and mental performance . Optional upgrades also allow it to mitigate fatigue ( by injecting adrenaline - not recommended for extended use ) and dispense medical supplies . Even after the Great War , Auto - Docs have remained a rare technology found in the possession of only a few individuals . Models . Mark I . The first model in the Auto - Doc line features four autonomous arms ( mounted with a surgery light , a combination scalpel / syringe , tongs and a multipurpose " hand " ) attached to a boxy central unit with a CRT control panel attached to its side . Although models of this type are capable of performing even implant installation , they are commonly considered to be obsolete and ancient , in part due to it incorporating proprietary technology , not compatible with later models , making maintenance difficult . It only appears in the Mojave Wasteland and the Sierra Madre . Mark III . Visually identical to the Mark I model , it is more popular and widespread and parts of it are fully interchangeable between different units . It includes a separate diagnostic module that ' s prone to burning out after prolonged use . It only appears in the Mojave Wasteland . Mark IX . A fully stationary automatic doctor , it is made up of a ventilated cylindrical chamber with automated surgical tools mounted in the ceiling and a CRT control panel mounted on the side . When in use , blue lights circle along the top and bottom of the device . Visually , it strongly resembles a Pulowski Preservation shelter . It only appears in the Sierra Madre , Big MT and the Divide . Sink model . A unique prototype and the most advanced model of Auto - Doc . It was built by Dr . Mobius in The Sink in the Big MT before he left the Think Tank . It has a personality profile programmed in a holotape allowing it to talk in a stereotypical 1940s military drawl and possess a simple personality . In addition , it can sleep by snoring loudly and make passing comments on the general health on the person approaching it . It is autodidact and can perform complex medical procedures ( like implementing implants ) alone in contrast to other models demanding someone to apply the procedure . It can give a basic physical exam , cure radiation sickness , lacerations , broken bones and chemical addictions , give a haircut , provide facial reconstruction , implement implants , switch out brains , spines , hearts and perform psychiatric evaluation . Unknown model . A stationary type , this large device usually occupies an entire room , but offers a lot more versatility - it comes with its own clamps and braces to secure the patient in , completely independent of a surgery bed , an anesthesia reservoir and a set of automated routines . They also include a built in drug synthesizer that can be programmed to create a variety of chemicals like endorphin blockers . Also , it can brew synthetic substitutes for otherwise - addictive substances . These synthetics were used as placebos for chem addicts before the Great War . A function called " priority operator override " can also be used to program non - standard procedures into treatment routines ( such as injecting sodium tri - ethylene ) . It only appears in New California .
