->''"Latex and steel, zeros and ones make up my son. This world gave me no child so I built one."''
-->-- '''[[Franchise/MegaMan Dr. Thomas Light]]''', [[Music/TheMegas The Message From Dr. Light]]

Although mechanical beings are not 'related' in any true biological sense, the concept of robots being 'family' is nevertheless a common trope in sci-fi. After all, if robots can [[RoboticSpouse get married]], be [[RidiculouslyHumanRobots ridiculously human]], and be [[RobotBuddy loyal friends]], it makes perfect sense that robots would [[DoAndroidsDream develop]] their own sense of family.

How seriously this term is applied usually depends on [[RidiculouslyHumanRobots how human-like]] they are, how well characters [[JustAMachine regard robots]], and how [[LighterAndSofter light]] the source material is. Sometimes the robots love each other just as much as any human family. Other times it's just a technical term used by humans.

The main types of family are as follows:

* '''Robot series:''' All of the robots are from the same 'series' which usually share similar designs and are usually all based off an original prototype. This can sometimes even apply to more advanced machines that follow the 'spirit' of the original design or carry on [[LegacyCharacter their legacy]].

* '''Same creator:''' All of the robots have the same creator, making them a 'father/mother' to all the robots and making them 'siblings'. Sometimes the creator actually treats their creations like children, although some can get a bit [[MadScientist carried away]]. Expect a [[YoureNotMyFather You're Not My Father/Mother]] if a robotic 'son/daughter' [[TurnedAgainstTheirMasters turns against their creator.]] This usually overlaps with the above example, since the same creator would make similar robots. A builder treating his creation as his child is a trope dating back at least to ''Literature/{{Pinocchio}}.''

* '''Replacements, clones or copies:''' When a robot is [[BetaTestBaddie replaced]] with a better model, [[MechaMooks mass produced]], or [[CloningBlues copied]] by another party, this technically makes the two robots 'brothers' even though they're essentially the same person in terms of design. One of the robots is usually an [[ShadowArchetype evil]] version of the other, especially if they're angry of the existence of their 'sibling'.

* '''Robot family:''' In a series where robots are allowed to live amongst humans, many robots form their own real robot 'family', usually by having robot parents making or adopting their children. Sometimes the siblings will look like they're 'related' but sometimes they can be mismatched.

This trope is the most [[IncrediblyLamePun 'family friendly']] kind of relationship that can happen between creators and fellow robots. Other kinds would be [[ThankTheMaker their creators being gods]], an empty technical term because the robots are [[SlidingScaleOfRobotIntelligence barely sentient]], or the robot [[AIIsACrapshoot considers itself above]] such petty 'relations'.

Also compare RoboticSpouse for when a human has a romantic attachment to a robot, which can lead to a robot family when they adopt/make children. All of these types of robot family can include a RobotKid, often playing the role of "son" or "daughter".



* One Duracell ad campaign featured the Puttermans, a nuclear family of [[Series/LeaveItToBeaver domestic suburbanites]] that ran on giant Duracell batteries.

[[folder:Anime and Manga]]
* ''Manga/AstroBoy'': The UrExample, Astro has his sister Uran (and a brother named Cobalt in the manga) as well as his own robotic parents, not to mention his 'sibling' Atlas that was based off his blueprints/made by the same creator.
* ''Manga/{{Chobits}}'': Chii has her sister [[spoiler:Freya]]. The chobits themselves were created to be surrogate daughters for a woman who couldn't give birth.
* In ''Manga/PrincessResurrection'' each of the royal siblings have there own android who are also called siblings: [[AddedAlliterativeAppeal Flandre, Francisca, Francette, Flanders and Franz]] - and probably several more.
* ''Anime/TransformersRobotsInDisguise'' brought us the Autobot Brothers: Prowl, X-Brawn and Sideburn. Optimus Prime and Ultra Magnus are also brothers.
* In ''Manga/MahouSenseiNegima'', [[RobotGirl Chachamaru]] considers [[PerversePuppet Chachazero]] her older sister because both of them were created from Evangeline's magic. She also views all of the robots that her other creators (Chao and Hakase) made as her younger siblings. She also views her three creators as her parents.
* Machine People in the Anime/{{Leijiverse}} (featured in ''Manga/GalaxyExpress999'' and many others) fall into this category; they're all transformed humans, for the most part, but sometimes we see scenes of things like in "Cosmo Warrior Zero" where robot mommies are running away from explosions holding their robot babies.
* Title robot Signal in ''Manga/TwinSignal'' considers Pulse to be his brother because they were created by the same man. He also considers the human little boy Nobu to be his little brother because, personality-wise, he was programmed to act that way -- but he says he'd think of Nobu that way even if it ''wasn't'' in his programming.

[[folder:Comic Books]]
* The Franchise/DCUniverse has Dr. Magnus' ComicBook/MetalMen, who are all people who were accidentally transferred into robotic bodies. [[AlternateContinuity Sometimes]].
** In most versions, they're simply a small group of robots all built by the same guy, so they have become TrueCompanions. Generally speaking they don't consider Doc to be their "father" -- after all, Platinum is ''in love'' with him.
* Comicbook/{{Ultron}}, the premier KillerRobot of the MarvelUniverse, has created a whole bunch of other robots and cyborgs (The Vision, Jocasta, Alkhema, Antigone, Victor Mancha) whom he explicitly refers to as a family. Most of them have ended up betraying him. Ultron's family also includes his creator Hank Pym and the various people whose brain patterns he's copied into his creations. Things get extra-complicated when you throw in Vision's children with Scarlet Witch - his non-robot, human children, who are still related to their parents even though they were reincarnated and born to different families...yeah. The end result is a robot being the grandfather of two organic individuals.
** Taken one step further in the 2015 ''[[ComicBook/TheVision2015 Vision]]'' series, in which he creates a robotic wife, son, daughter, and eventually even a dog.

[[folder:Fan Works]]
* ''{{Franchise/Tron}}''-universe {{Fanon}} will tend to [[PlayingWithATrope play with this trope]], particularly in regards to Clu, Sam, and Flynn (usually played for DarkFic) or with Alan and Tron (often played for HurtComfortFic). Complicating matters in that universe, Programs don't appear to have the same concept of "family" as humans and the fact Programs [[ThankTheMaker see humans as their deities]].
* ''FanFic/TheBridge'' gives us a {{Cyborg}} variant of the trope with Gigan and Megalon. By merit of having the same creators who made them, both organics and mechanical parts included, the latter considers the former his older brother. Gigan might be a bit less vocal about it, but he does acknowledge the younger kaiju as relation.


[[folder:Films -- Animated]]
* The Creator/TwentiethCenturyFox movie ''WesternAnimation/{{Robots}}'' has this, most notably with a main character who has a mom and dad.

[[folder:Films -- Live-Action]]
* In the movie continuity of ''[[Film/TransformersFilmSeries Transformers]]'' there are several nods to the robots having families. Optimus Prime and Megatron are implied to be brothers (whether literal or metaphorical isn't entirely made clear), the 3 Arcee bikes have been referred to as sisters by some sources, Jetfire mentions having a mother and a father (who was apparently "the first wheel"), The Fallen and the Dynasty Of Primes are all brothers and Optimus is a great descendent of one of them. Oh and The Twins, who are... [[ExactlyWhatItSaysOnTheTin robot twins]].
* ''Franchise/MarvelCinematicUniverse'': Tony Stark builds a number of [=AI=]s that join the "family business" so to speak. DUMM-E, J.A.R.V.I.S. F.R.I.D.A.Y., and partially, [[spoiler: The Vision]] either help him in Stark Industries and/or in Avenging. In fact, ''Film/AvengersAgeOfUltron'' plays out like a teenager rebelling against his father and Tony even jokes that Ultron is "breaking your old man's heart".

* Madeline Ashby's ''Machine Dynasty'' series has [[VonNeumannMachine von Neumann]] androids who eat plastics, metals, and e-waste to grow and give birth to robot babies. Some of them marry humans and raise children together.

[[folder:Live Action TV]]
* Data and Lore were "brothers" on ''Series/StarTrekTheNextGeneration'' and both acknowledged their creator Dr. Soong as their father. And later Data made an android of his own named Lal, who was his "daughter."
* In ''Series/RedDwarf'', [[spoiler: Kryten has a brother named Able]] and they were both created by the same woman.
* ''Franchise/SuperSentai'' / ''Franchise/PowerRangers''
** The villains of ''Series/ChourikiSentaiOhranger'' / ''Series/PowerRangersZeo'' are an evil robot royal family.
** Signalman, a robot space policeman from ''Series/GekisouSentaiCarranger'', has a wife and son on his home planet. This ''wasn't'' carried over to his PR counterpart.
* In the "Baby" episode of ''Series/YoGabbaGabba'', we find out Plex the robot has a niece named Plexy.

[[folder:Tabletop Games]]
* The TabletopGame/{{Mystara}} setting for ''TabletopGame/DungeonsAndDragons'' had the Hephaestons, a race of literal iron giants. They reproduced by a male and a female literally forging a child, and then adding a bit of molten metal from each of their own bodies to grant it life.
* In ''TabletopGame/HcSvntDracones'' "Cogs" have digital brains designed to grow and develop like organics. And that means they have childhoods where they go through a series of progressively larger chassis over twenty years. Generally they're raised by other Cogs but "inter-racial" families and adopted siblings are mentioned as occurring between Vectors and Cogs.
** The Core: Extended book elaborates. They're actually capable of "sexual" reproduction using an internal manufacturing device that constructs a new "brain" and newborn chassis from a combination of both parents' blueprints, or genes. And it's possible to make sperm with genomes translated from a Cog's chassis as well.

[[folder:Video Games]]
* ''VideoGame/MegaMan'': The next most famous example, Mega Man/Rockman, Roll, and Proto Man/Blues are all considered siblings, as it wasn't obvious from the ThemeNaming. Doctor Light is usually considered to be a father to all of them.
** Also, it was widely speculated that Dr. Light built the three in a sense that he actually wanted to have his own chidren.
** Heck, the Robot Masters of ''1'', ''9'', and ''[[VideoGame/MegaManPoweredUp Powered Up]]'' can count as well. Not that it stops some of the ''Powered Up'' robots from [[BrotherSisterIncest hitting on Roll]].
** ''VideoGame/MegaManX'' also counts, both being a creation of Light as well as being carrying on Mega Man's 'legacy'.
** Iris and Colonel are considered brother and sister because they were supposed to be the same reploid, but were split into two. Also Techno and Midi, who shared the same CPU.
** If we're going by the '''same creator'''-type of family like Dr. Light, don't leave [[BigBad Dr. Wily]] out of it either. His family, however, is just as rebellious as ''he'' is. Take a look at Bass [[spoiler:and Zero]], for starters.
*** [[spoiler:And in ''VideoGame/TatsunokoVsCapcom'', Dr. Wily appears in Zero's ending, ''and he actually called Zero his son!'']]
** The Four Guardians in ''VideoGame/MegaManZero'' are regarded as siblings by some portions of the fandom for convenience, due to their common origin and purpose.
** In ''VideoGame/MegaManXCommandMission'', Professor Gaudile is a recluse scientist who built the Force Metal Generator and Cinnamon, to whom he is an OverprotectiveDad, sheltering Cinnamon for most of her early life.
* In ''VideoGame/ChronoTrigger'', Robo and his fellow R-series robots are never actually called "brothers", but they do share a bond - or at least they [[FaceHeelTurn used to]].
* In ''VideoGame/{{Persona 3}}'', Aigis and [[spoiler:Metis]] are said to be sisters...
** Also, all of the anti-shadow weapons that were built with Aigis are referred to as her sisters.
* In ''VideoGame/{{Xenosaga}}'', MOMO's relationship with the 100-Series Realians who preceded her is also akin to sisterhood.
* The various members of the E-100 series in ''[[SonicAdventureSeries Sonic Adventure]]'' are considered siblings. This becomes weird at the end of E-102's story, when [[spoiler:it turns out that the bird powering his body is part of the same family as the bird powering his older brother]].
* This can be done in ''VideoGame/TheSims'' of all places, particularly Sims 2. Servo units are fully functional characters, just with an unusual look and weird wants/needs. They also inherit all their creator's talents. After making one Servo, the Servo can create others, easily filling a house. Since Servos are essentially immortal they will usually outlast their creators by a long shot. It's entirely possible to have a single servo and it's descendants max out the game (learning all skills et all) for you. The Sims 3 also has this. Any Simbot that is built will regard the person who built them as their parent. If the person who built the Simbot has any biological children, then the Simbot will regard them as half-siblings. Simbots can also build their own Simbot children.
* In ''VideoGame/TalesOfHearts'', Chlorseraph and Clinoseraph, who have similar designs and were created for the same purpose, are referred to as brothers.
* The W-Numbers of ''VideoGame/SuperRobotWarsOriginalGeneration'' have varying degrees of "family" relationships. As (supposedly) the only one of the group to develop real human emotions, W17 starts to see her fellow androids as something like siblings, but only after defecting to the opposite side. As such, she's the first that their creator starts to see as a "daughter". But the closest sibling relationship between two W-Numbers is in the GaidenGame ''VideoGame/EndlessFrontier'', with W07 and [[spoiler:W00, who is actually an artificial human rather than an android. When his origins are first revealed, they teasingly refer to each other as "Brother Zero Zero" and "Sister Seven".]]
* The plot of the ''VideoGame/{{KOLM}}'' series has yet to be fully explained, but the robotic protagonist regards his VoiceWithAnInternetConnection as his "mother," and at one point says that the robots that're trying to kill him are his "brothers." [[spoiler:Subverted: In the end, he finally remembers "[[BrainUploading when I was made of meat]]," and in the second game his "sister" turns out to be human.]]
* The ''VideoGame/MagicalGirlLyricalNanohaAsPortable'' series has the Eltrian Gears, a.k.a, [[spoiler:Amitie and Kyrie Florian, who were created by an intelligient, bumbling scientist who accidentally overdid their personality chips and so decided to raise them as his daughters]].
* According to ''VideoGame/DungeonsAndDragonsOnline'', [[TabletopGame/{{Eberron}} warforged]] often consider others from the same factory to be family of sorts.
* A large plotpoint in ''VideoGame/Fallout4''. A group called the [[MorallyAmbiguousDoctorate Institute]], who replace people in the Commonwealth wasteland with their own, fabricated human clones of the same called "Synths". Unfortunately for the Institute, it seems that when you create faultless synthetical humans, you also make intelligent, free-thinking life. The [[UndergroundRailroad Railroad]] works to liberate these people... And sometimes the less sentient ones. And toasters, if you ask the Institute.

* ''Webcomic/TheInexplicableAdventuresOfBob”''-- Molly built a robot named Roofus who calls her "Mom."
* ''Webcomic/NeverMindTheGap'': Robots have family units, and raise children. [[{{Robosexual}} Humans and robots can marry]], as well as have [[DesignerBabies robot children]].
* ''Webcomic/{{SSDD}}'': The [[KillerRobot Inlay]] [[ChessMotifs King]] "Arthur" refers to his retinue of custom Knights as his "sons" (named after Knights of the Round Table, naturally), and calls the fabricator AI that built him his "mother" to annoy her.
* During the first arc of ''Webcomic/GunnerkriggCourt'', the newly-assembled Robot calls Antimony "Mommy". After he returns later in the comic, he seems to have outgrown this, but still defers to her.
* Roombas in ''Webcomic/QuestionableContent'' can breed. No-one is sure how, least of all the manufacturer. Also Pintsize was shocked when a documentary on how [=AnthroPCs=] are made involved two [=AnthroPCs=] having sex and he thought one of them might be his mom.

[[folder:Web Original]]
* The WALL-E forum role play actually has a detailed analysis of what constitutes a robot family, detailed [[http://walleforum.com/index.php?topic=8369.msg506384#msg506384 here.]]
* In ''WebOriginal/OrionsArm'' Clade Faber usually form "reprogroups" that cooperate to construct new vecs and program them with partial copies of their personalities.

[[folder:Western Animation]]
* ''WesternAnimation/MyLifeAsATeenageRobot'': Jenny has several "sisters" who are actually failed prototypes created by her inventor who have since been shut down and locked up in the basement.
* [[WesternAnimation/TransformersGenerationOne Original Transformers]] Sideswipe and Sunstreaker are considered brothers. Also, Optimus Prime and Elita One (who [[BrotherSisterIncest are apparently romantically involved]]) consider Alpha Trion their father, as he rebuilt them from their previous civilian forms into their current states when they were damaged.
** Popular {{Fanon}} states that Starscream, Thundercracker, and Skywarp are brothers, due to their being [[PaletteSwap identical but for coloration]].
* Rattrap from ''WesternAnimation/BeastWars'' made a throwaway reference to his [[ShoutOut "Great Aunt Arcee"]].
** ''WesternAnimation/TransformersAnimated'' had Jetfire and Jetstorm refer to each other as brothers. Unlike the likes of Sideswipe and Sunstreaker, an explanation is provided: they came from a single [[OurSoulsAreDifferent spark]] that split into two at 'birth'.
*** Transformers in general has plenty of these. Of course, being {{Mechanical Lifeform}}s as opposed to just simple robots helps. However, the Transformer life cycle is addressed on occasion, and as those tidbits add up, the Protoforms/Sparks/Matrix/Lifegiving MacGuffin stuff makes it ''extremely'' unlikely that the words "When two robots who love each other very, very much..." are involved, so how you get relatives is still a good question. [[http://tfwiki.net/wiki/Relatives See here for more info]].
** The Aligned Continuity implies that Orion Pax (the future Optimus Prime) is a descendent of Prima, one of the thirteen Primes, the original Cybertronians created by Primus himself. [[spoiler:Except not. ''Covenant of Primus'' reveals that Orion Pax was the reincarnation of the last of the Thirteen to be created: Optimus Prime. This doesn't make Optimus Prima's descendent -- it makes him, for all intents and purposes, Prima's ''brother'']].
* One episode of ''WesternAnimation/{{Robotboy}}'' involved Robotboy finding out he had a prototype older brother ("Protoboy") that had to be shut down by Moshimo (their creator) after he was turned evil by Kamikazi and went [[AxCrazy insane]]. The episode revolves around the ever-naive Robotboy finding the deactivated Protoboy in Kamikazi's Rejects closet and turning him back on. The results aren't pretty.
** Similarly, a different episode involved Moshimo making a companion ("Robotgirl") for Robotboy. So Robotboy, Robotgirl and Protoboy are all siblings, technically.
* ''WesternAnimation/BigGuyAndRustyTheBoyRobot'' uses the "same creator" version, in that Rusty and the woman who built him have a mother/son relationship. When she explains to an older scientist that she based Rusty off his research, Rusty starts calling him "Grandpa".
* In ''WesternAnimation/YoungJustice'', [[MadScientist T. O. Morrow]] considers his four element-controlling robots (Red Tornado, Red Inferno, Red Torpedo, and Red Volcano) to be his children, and they refer to him as "father", even though Tornado is no longer remotely loyal to him and [[spoiler: Red Volcano kills him and hijacks his world-domination plan]]. They also refer to each other as siblings. In a rather heartwarming moment, Red Tornado [[spoiler:locates the real Morrow, a bed-ridden old man on life support, and promises to take care of him just like any other loving son would do for his father.]]
* Skyquake and his PaletteSwap twin, Dreadwing, from ''WesternAnimation/TransformersPrime'', are the closest to what can be considered robot relatives. Brothers in this case, as they share a split spark.
** ''Twin'' brothers, in fact, with a form of TwinTelepathy. Dreadwing felt it when Skyquke died. [[RoaringRampageOfRevenge He didn't take it well.]]
* In ''WesternAnimation/{{Futurama}}'' robots are apparently capable of sexual reproduction. As such families of robots are fairly common, Bender has at least two illegitimate offspring.
** A recent episode explains it: while most robots are made in factories, two robots can also reproduce sort-of-sexually, using a "randomized combination equation" or something like that, which pulls parts randomly from both parents to form a single new robot.
*** He also refers to the factory robot that built him as his "mother", and Flexo is treated as some vaguely defined family member due to being the same model and them both having serial numbers expressible as the sum of two cubes.
* An episode of ''WesternAnimation/TheJetsons'' has George getting a blueprint of Rosie the robot maid's predecessor in her series as an inverted Mother's Day gift, as that's the closest thing she had to a mother.
* In ''WesternAnimation/JimmyNeutronBoyGenius,'' Jimmy decides that [[SiblingsWanted he wants a little brother]], and builds one. When "Brobot" becomes annoying, however, he decides to build him robot parents, and the three fly off to live together on the moon. They come back in at least one episode.
