[[caption-width-right:350:Not just a [[ButtMonkey badly-dressed dork,]] but a badly-dressed dork with his own HumongousMecha]]

A scientist who specializes in building or maintaining robots.

If he is a MadScientist, this skill will probably manifest as an ability to effortlessly manufacture [[MechaMook Mecha Mooks]] in bulk. Robots don't have to be his only area of expertise (as a mad scientist, he's probably also an OmnidisciplinaryScientist), but he's a Robot Master if robot-making is far and away his most commonly displayed skill. For instance, Doctor Doom is a scientist who builds robots periodically, but fellow ''ComicBook/FantasticFour'' enemy the Mad Thinker builds robots virtually every time he appears.

[[SmartPeopleBuildRobots Just building one robot doesn't qualify you for this trope.]] This is for people whose resumés are more than 50% taken up with robot-building or at least robot-fixing.

Not to be confused with the ''VideoGame/MegaMan'' Robot Masters, though this trope does apply to their creators.

May or may not overlap with MarionetteMaster. Many [[TheIgor Igors]] qualify, depending on their bosses' area of expertise. Compare with DroneDeployer and TheTurretmaster (for different kind of "robots") and WickedToymaker.


* [[Comicbook/WonderWoman Wonder Woman's]] nemesis, [[http://www.seanbaby.com/hostess/v2wonderwoman01.htm the Robot Master!]] She defeats him with [[DeliciousFruitPies Twinkies.]]

[[folder:Anime & Manga]]
* Dr. Gero from ''Manga/DragonBall Z'' made many robots to fight Goku, though some of them are cyborgs (17, 18, and himself) or artificial lifeforms (Cell).
* Dr. Vegapunk of ''Manga/OnePiece''. This may change later on, as he's pretty much stated to have [[OmnidisciplinaryScientist a whole plethora of other accomplishments under his belt]], but his most prominent role in the story thus far is creating a small army of [[MechanicalMonster Pacifistas]] for the World Government.
* Jail Scaglietti from ''Franchise/LyricalNanoha.'' He also builds cyborgs.
* Winry of ''Manga/FullMetalAlchemist'' is constantly repairing robotic limbs and such.
* All Incarnations of Dr. Hell from [[Anime/MazingerZ the]] [[Anime/{{Mazinkaiser}} Mazinger]] [[Anime/ShinMazinger series]] are this to varying degrees.
* Dr. Rotwang from ''Anime/TigerAndBunny''.
* Engineer Sakaki from ''Anime/{{Patlabor}}.''
* Doctor Tenma and Doctor Ochanomizu from ''Manga/AstroBoy.''
* ''Doll'' by Mitsukazu Mihara is an anthology series about humans interacting with robots, so it's only natural that many of its characters are robot specialists.
* Norman Burg in ''Anime/TheBigO'' knows how to maintain a [[HumongousMecha megadeus]] -- though being an [[LaserGuidedAmnesia amnesiac]] like everyone his age in Paradigm City, he doesn't remember how he learned this skill. He repairs and maintains the Big O for Roger.

[[folder:Comic Books]]
* Dr. Will Magnus, creator of the ''ComicBook/MetalMen.''
* The Mad Thinker from ''ComicBook/FantasticFour''.
* Toyman from ''{{Superman}}'' can build lifelike androids, but prefers to make his killer robots look like toys.
* ''JusticeLeagueOfAmerica'''s Dr. T.O. Morrow, creator of Red Tornado, Amazo, Tomorrow Woman, and assorted other bots. They [[AIIsACrapshoot tend to rebel on him,]] but since he's evil, that's usually a good thing.
* Alistaire Smythe, creator of the [[SpiderMan Spider-Slayers.]]
** Also minor Spidey antagonists Armada and Future Max.
** And minor character Mendel Stromm, who actually calls himself "Robot Master".
* Dr. Abel Stack, who built [[ComicBook/NextWave Aaron Stack]] [[Creator/JackKirby the Machine Man.]] He also helped build all the previous robots in Aaron's series, who all [[CrushKillDestroy went mad.]] The reason Aaron turned out all right is that Abel actually [[RoboFamily raised him as a son.]]
** Of course, [[CharacterizationMarchesOn years later,]] [[SufficientlyAdvancedAliens the Celestials]] kidnapped Aaron, causing him to suffer a nervous breakdown and turn into the [[DeadpanSnarker snarking,]] [[JerkWithAHeartOfGold endearingly neurotic]] JerkAss we know from ''{{ComicBook/Nextwave}}'', but that's another story.
* Bolivar Trask, creator of the ComicBook/XMen's robot nemeses, the Sentinels.
* The (possible) TropeNamer from Marvel's ''Comicbook/TheTransformers'' comic is actually an [[InvokedTrope invocation of this trope]]: failing comic-book writer Donny Finkelberg is enlisted by the government to pose as the "Robot Master" and make threatening speeches on TV taking responsibility for the Decepticons' actions, [[MissingStepsPlan to keep the population from panicking]]. HilarityEnsues when the 'cons found out that some dumb squishy was pretending to be their master. In fact, when Megatron awakens, he decides to keep Finkleberg around to continue the charade, since he could make it look like ''all'' robots are under his control, [[HeroWithBadPublicity making it harder for the Autobots to enlist human allies]]. It doesn't ''quite'' work in the long run, since it's kind of hard to explain why one guy would have two sets of robots fighting each other, but it becomes moot when Finkleberg manages to escape.
* Despite being a robot himself, ComicBook/{{Ultron}} would certainly count. He built ComicBook/TheVision, Jocasta, [[Comicbook/{{Runaways}} Victorius,]]and Alkhema, as well as countless duplicates of himself--usually just replacement bodies for when he inevitably gets destroyed at the end of each appearance, but he has built armies of these duplicates on a couple of occasions (with the predictable ConservationOfNinjitsu in full effect).
* The Followers of the Light from [[Franchise/MarvelComics Marvel's]] ''Shogun Warriors'' comic are aliens who built the titular [[HumongousMecha humongous mecha]] to fight [[{{Kaiju}} giant monsters.]]
* Tyranik from Franchise/ArchieComics's ''ComicBook/ManTech'' series was [[MadScientist driven mad]] by the same [[NeglectfulPrecursors ancient]] "knowledge ray" that taught him about robotics, so he wants to wipe out mankind and replace it with robots.
* The Katayanagi twins from the ''ComicBook/ScottPilgrim'' series, though the building itself happens off-screen. In the comics, anyway; the film changed them to techno-themed {{Musical Assassin}}s
* Baxter Stockman from the original ''Franchise/TeenageMutantNinjaTurtles'' comics is a computer expert who builds small "Mouser" robots and uses them to commit crimes.
* The Assemblyman from ''ComicBook/AstroCity''.

* Dr. Totenkopf in ''Film/SkyCaptainAndTheWorldOfTomorrow''.
* Sebastian in ''Film/BladeRunner.'' "They're just toys, really..."
* Gene Simmons' Dr. Luther from ''Film/{{Runaway}}'' not only builds killer drones, he also sabotages existing household robots so they'll [[TurnedAgainstTheirMasters go berserk]] on command.
* The original [[Franchise/{{Frankenstein}} Dr. Frankenstein]] (named [[DependingOnTheWriter Victor or Henry)]] comes from [[Literature/{{Frankenstein}} the novel,]] but the ExpandedUniverse of the movies gives him various relatives and assistants to carry on his legacy.
** ''Film/BrideOfFrankenstein'' introduces his sinister old mentor, Dr. Pretorius.
** ''Film/SonOfFrankenstein'' is ExactlyWhatItSaysOnTheTin with the doctor's son, Wolf Frankenstein, and also introduces the doctor's old assistant, [[TheIgor Ygor.]][[note]] In the [[Film/Frankenstein1931 original film]], the doc's hunchbacked assistant is named Fritz, but Creator/BelaLugosi's character [[TheIgor Ygor]] is the assistant everyone remembers.[[/note]]
** ''Film/TheGhostOfFrankenstein'' introduces the doc's ''other'' son, Ludwig.
** ''Film/HouseOfFrankenstein'' has Dr. Neimann, implied to be Ygor's brother. And he has his ''own'' [[TheIgor hunchbacked assistant!]]
** ''Film/YoungFrankenstein'' has the doc's descendent, Dr. Frederick [[InsistentTerminology "Frahnkensteen,"]] and ''his'' [[TheIgor hunchbacked assistant,]] Igor (pronounced EYE-gor).
* [[AIIsACrapshoot SkyNet]] from ''Franchise/{{Terminator}}'' builds its own troops.
* The film version of [[Film/IronMan Tony Stark]] is portrayed as one. While he prefers to build high-tech armor for himself, he has also programmed complex AIs such as JARVIS and keeps a couple of robotic arms that he built as a kid as his pets. This escalates in ''Film/IronMan3'' when he has JARVIS take control of his extra suits; and then in ''Film/AvengersAgeOfUltron'' he has a set of autonomous "Iron Legion" bots and is a major factor in creating both Ultron and Vision.
* Nathan from ''Film/ExMachina.''

* Creator/IsaacAsimov's Dr. Susan Calvin (from ''I, Robot)'' is a robo-''psychologist.''
* Victor Literature/{{Frankenstein}}, although he only ever got around to building one and a half androids (two, in [[Film/BrideOfFrankenstein the film sequel.)]]
* Doctor Impossible, from ''Literature/SoonIWillBeInvincible'', uses a wide variety of tech but specialises in robots and doomsday devices.
* Dr. Emil Lang from ''{{Anime/Robotech}}'' is the world's leading authority on Robotechnology. "Robotechnology" actually refers to ''all'' types of alien-derived technology on Earth, but the most visible type is all the HumongousMecha running around. He eventually succeeds in building a [[RidiculouslyHumanRobot sentient android,]] [[RobotGirl Janice Em.]] Lang is a [[AscendedExtra major character]] in the ''Robotech'' [[ExpandedUniverse novels and comics,]] although he only has a couple of brief cameos in the original TV series.
* Literature/AdamLink's [[MotherlyScientist "father,"]] Dr. Link.

[[folder:Live Action TV]]

* Grant Imahara on ''Series/{{Mythbusters}}''.
* The MadScientist in "Cybernauts" episode of ''Series/TheAvengers'' builds two robots, which Steed foils by getting them to destroy each other.
* ''Series/BuffyTheVampireSlayer''. Warren built the April-bot, the Buffy-bot, and finally a robot of himself. Willow shows herself to be quite good at fixing/reprogramming the Buffy-bot when needed.
** In season 9, Andrew uses Warren's lab to create another Buffy-bot and switches it's consciousness with the real Buffy.
* ''Series/WonderWoman'': "The Deadly Toys" features Frank Gorshin of [[TheRiddler the Riddler]] fame from [[Creator/AdamWest Adam West's]] ''{{Series/Batman}}'' as an [[BigBad evil toymaker]]. His [[EvilPlan plan]] includes making a robot Wonder Woman to challenge the real Amazon Princess.

[[folder:Manhwa and Korean Animation]]
* The human cast of ''Animation/CubixRobotsForEveryone.''

[[folder:Tabletop Games]]
* ''TabletopGame/{{Champions}}'':
** Robot Gladiators supplement. Dr. Anton Wolcott, Chief Roboticist of the Interstellar Gladiator Authority.
** Mechanon probably counts: as a robot, he used automated factories to make improved versions of himself.
* EvilSorcerer variant: Xin, the High King of ancient Thassilon in ''TabletopGame/{{Pathfinder}}'', was enamored with powerful clockwork automatons, and in fact was entombed in a "living" clockwork sarcophagus.
** House Ardoc in the city of Kaer Maga specializes in animating golems and other magical constructs.
* The wizard Trioband in ''TabletopGame/ForgottenRealms'', who created various specialized metal automatons.
* In ''TabletopGame/SentinelsOfTheMultiverse'', the villain [[KillerRobot Omnitron]] builds Drones to fight the heroes, while the hero Unity creates mechanical golems that do her fighting for her.
* ''TabletopGame/MagicTheGathering'': Both of Tezzeret's [[GuestStarPartyMember planeswalker cards]] have abilities that search the player's deck for artifacts and turn them into powerful creatures.

* The owner and employees of Rossum's Universal Robots in Karel Capek's play "R.U.R.," which famously coined the word "robot."
* Though only the first film would retain the name Fritz (later films renamed him Ygor or Igor), Dr. Frankenstein's hunchbacked assistant Fritz actually dates back to early 19th century stage adaptations of Mary Shelley's novel.

[[folder:Video Games]]
* Dr. Wily and Dr. Light from the ''VideoGame/MegaMan'' games, whose main robots are coincidentally known as Robot Masters.
* ''Franchise/SonicTheHedgehog'''s diabolical Doctor Robotnik, whose portfolio includes trying to turn everyone in the world into a robot.
* Lord Agony from ''VideoGame/LocksQuest''.
* In ''VideoGame/ProfessorLaytonAndTheCuriousVillage'', we have Bruno, [[spoiler:who built ALL of the inhabitants of St. Mystere with the exception of the late Baron Reinhold's daughter, Flora]]
* Purge from ''VideoGame/SpaceChannel5 Part 2'' makes hundreds of robots to face off against Ulala. Apparently he's so talented, he mass-produced the Peace Carrier 8 times in under a day.
* Robotics Masterminds in ''[[VideoGame/CityOfHeroes City of Heroes/Villains]]'' are playable robot masters.
* Gaige the Mechromancer and her KillerRobot / ScienceFair project D374-TP a.k.a. "Deathtrap" from ''VideoGame/{{Borderlands 2}}''.
* In theory, this is 0's ''job'' in Big MT in ''VideoGame/FalloutNewVegas Old World Blues''. In practice, while he's not too bad at the mechanical side of things (his modification of [=RobCo=]'s Securitrons ''are'' more powerful, despite having been in the open seemingly without maintenance for centuries), his software skills are... not quite up to the task (his robots either a) have gone berserk or b) hates their job). Mr. House of New Vegas has elements of this himself -- while his skills extended quite a bit beyond robots, it ''was'' a major focus of him and the company he created, [=RobCo=], and in the modern day his influence on the outside world mainly occurs through controlled and sometimes modified Securitrons.
* The Mechanist in ''VideoGame/{{Fallout 4}}'' is an expert of robotics and has an army of robot for terrorizing the Commonwealth and killing everything coming across their path, complete with a factory as the lair to mass produce the robots. You can become one after acquiring the Robot Workshop as well.
* Lightspeakers from ''[[VideoGame/NexusWar Nexus Clash]]'' are fragile, cheerful angels devoted to defending justice and protecting the innocent by building and maintaining an army of relentless robotic minions. They're much more positive than most examples of this trope, but their armies can be incredibly dangerous if they fall prone to the BlackAndWhiteInsanity that often tempts angels in the Nexus.
* ''Franchise/TheElderScrolls''
** In the series' {{backstory}}, the extinct [[OurDwarvesAreDifferent Dwemer]] were masters at creating mechanical "[[MechaMooks animunculi]]", ranging from miniature [[SpiderMech spider centurion]] workers to sphere and steam centurion soldiers to full blown HumongousMecha. As the Dwemer were known to tinker with the "earthbones" (essentially the laws of physics and nature in the ''ES'' universe), they could make their creations [[RagnarokProofing impervious to wear and tear]], meaning that many are still up and running even thousands of years after their disappearance.
** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'':
*** Edwinna Elbert, Stewardess of the Ald-Ruhn Mages Guild, studies Dwemer creations. If one brings her a copy of a certain rare book, she'll mention how she wants to be one of these, believing [[GlorySeeker it will make her famous]].
*** In the ''Tribunal'' expansion, one can meet Ignatius Flaccus in Mournhold. Ignatius spends his time restoring Dwemer centurions to use as combatants in his robot arena. [[spoiler:Of course, he quickly learns the hard way that Dwemer creations tend to [[AIIsACrapShoot behave erratically]] if taken outside of Dwemer ruins]].

[[folder:Web Comics]]
* Agatha Heterodyne of ''Webcomic/GirlGenius''.
* In ''Webcomic/{{Homestuck}}'' the {{Troll}} Equius Zahhak is quite skilled at building robots and cybernetic limbs. He does this so that he can blow off steam by fighting killer robots.
* Rika, a British example from ''Webcomic/RPGWorld''
* In ''WebComic/TheAdventuresOfDrMcNinja,'' Sean "Dark Smoke Puncher" [=McNinja=] likes to build robot animals with laser vision and stuff. Their main job is to guard the family home, but that's just an excuse--he just likes making the suckers.
* Molly from ''Webcomic/TheInexplicableAdventuresOfBob'' builds lots of robots, [[SmartPeopleBuildRobots mostly for fun.]] Only one of them has turned out [[InstantAIJustAddWater sentient]] - the one made out of a milking machine. Two of the others were made of ''[[{{Snowlems}} snow;]]'' and of those, [[http://bobadventures.comicgenesis.com/d/20111101.html one]] could [[TransformingMecha transform]] into a giant ice [[SiegeEngines ballista.]] Yes.

* The Quintessons from ''WesternAnimation/TheTransformers.''
** The supercomputer TORQ-III from the episode "Day Of the Machines" is described as a "machine that can build other machines." When [[JerkAss Megatron]] reprograms TORQ to be hostile, TORQ commands all of the robots he's built to [[CrushKillDestroy go on a rampage.]]
** Any of the "medic" characters, like Ratchet or First Aid, would qualify for "maintaining" robots. As MechanicalLifeForms, they just think of it in different terms. Wreck-Gar and Alpha Trion would probably count, too.

* ''WesternAnimation/DuckTales'': [[BunglingInventor Gyro Gearloose]]. After [[RobotRebellion one disaster]], Scrooge [=McDuck=] specifically forbade Gyro from making robots, because AIIsACrapshoot. At least once Gyro attempted to get around this restriction by building [[GiantMecha piloted robots]] to get around the restriction, and rather than causing mayhem on it's own, the Beagle Boys simply stole them and caused mayhem anyway.
* Ziv Zoolander from the appropriately titled ''WesternAnimation/TheBOTSMaster.''
* In ''WesternAnimation/BoltsAndBlip,'' all the robots on the Moon were built by Dr. Tommy, except the evil MechaMooks who were built by [[NamesToRunAwayFromReallyFast Dr. Blood.]]
* Nora Wakeman, Jenny's "Mom" from from ''WesternAnimation/MyLifeAsATeenageRobot."
* Dr. Nightmare, a WesternAnimation/SpaceGhost villain who built [[MechanicalMonster Mechanical Monsters.]]
