Automatron ( companion ) The Automatron is a craftable companion for the Sole Survivor via the robot workbench . Background . Automatrons are specially crafted companions designed by the Sole Survivor to suit their own personal needs . They can be created , upgraded and renamed at a robot workbench , provided the resource requirements are met . They start with protectron parts without any armor , but individual parts from other robots can be scavenged , then built and attached , and upgraded further with quality armor attachments to meet ( or exceed ) factory quality . Created automatrons can have one of nine different voices , many with similar functionalities . All automatrons start with the male voice selected . The first four similar voices are the male , female and the relative processed variants of each . The voices all sound like well spoken servants , with the normal variation sounding like well recorded voices and the processed variants sounding more mechanical and modified . This voice type has personality subroutines that can be activated by selecting yes when requested when the robot is first created or by navigating through dialogue when the automatron is the current follower . These voice types are the only voice types that allow one to command the robot to self destruct , this is accomplished by navigating to the self destruct dialogue and giving the requested secondary confirmation , the unit will then begin the self destruct sequence and count down from ten , then it will explode . Another set of similar voices are the assaultron and sentry bot voices , both having the same voice lines , mimicking the voices of the respective robots . When asked to initiate personality subroutines both voices also respond with " " ERROR , command not recognized , " " although there are cases of both sentry bots and especially assaultrons with personalities ; they respond the same when asked to self destruct . The last three voices are different sounding beeps and clicks ( beep - click , beep - dark and beep - bright ) . Robots with these voices appear to exhibit emotion , but have no programmed personality subroutines in - game , and other robots upon encountering them may be heard exclaiming something along the lines of " " your personality appears to be an error in your program , have you considered having it purged . " " Robots with this voice type will respond with a ( negative beep ) when asked to self destruct . Which means it is impossible for automatrons with the last 3 voices to self - destruct . Automatrons will almost always fight on the side of the Sole Survivor , but may turn against them if they attack a settlement that the robot is a part of or was recently part of , even if they are the Sole Survivor ' s current companion . Creating an automatron . If one doesn ' t want to rely on the random chance of finding mods on robot bodies , they may want to invest in the Science ! , Robotics Expert , Blacksmith , Gun Nut and Armorer perks , as they ' re a requirement when it comes to crafting some of the more advanced parts . Optimization . When building an automatron , the head and both arms are optional - an automatron can be finished without them , although in such a case it will usually be lacking means of inflicting damage or interacting with its surroundings , as demonstrated by Bosun aboard the USS Constitution . Robot parts can be freely mixed with almost no restrictions , enabling the player character to create unique automatrons with a range of utility and offensive capability . Interactions with the player character . Range of interests . Automatrons are unconditional companions and their affinity cannot be changed .
