->''Woah! That's cheating, [[SubvertedTrope sneaking up]]. Do you have your legs on silent?''
-->-- '''The Tenth Doctor''' to Cybermen, "The Next Doctor"

This is a SoundFX trope relating to any robot, {{cyborg}} or MechanicalLifeform that makes mechanical creaking sounds when they move around. Most RealLife robots tend to make loud snaps and hissing noises due to the hydraulics or compressed air they use for movement and creaking noises mean that somebody has to pick up the oilcan ''stat'' unless they fancy replacing components.


[[folder: Anime And Manga ]]

* Chachamaru in the ''{{Negima}}!?'' second series had robotic noises added to accompany her movements.
* While the Combat {{Cyborg}}s in ''MagicalGirlLyricalNanoha'' are normally silent, body parts that have been damaged beyond a certain point will emit mechanical whirring sounds when they move, as shown in the hospital scene after the massive terrorist attack by Jail in ''[=StrikerS=]''.
* Dorathy from ''Anime/TheBigO'' makes very smooth mechanical sounds when she moves [[DependingOnTheWriter Depending on the Episode]]


[[folder: Fanworks ]]

* ''FriendshipIsWitchcraft'' features in episode 4 a discussion about robots. Episode 5 focuses on one, and her servos could use some maintenance. Not that anyone cares.


[[folder: Film ]]

* ''StarWars'' is guilty of this, with most civilian droids making odd pneumatic whining sounds whenever they move and military droids that have an inexplicable clanking sound accompany their every step, even while walking on grass.
* Although not technically a robot, [[PoweredArmor the powerloader]] used by Ripley in ''Film/{{Aliens}}'' makes satisfying hydraulic whirrs and clomps as it moves around.
* [[Film/ShortCircuit Johnny 5]] makes all kinds of noise when he moves around, but it's natural, since he's animatronic.


[[folder: Literature ]]

* In the first ''Literature/TheHitchhikersGuideToTheGalaxy'' book, Marvin deliberately makes clanking and labouring noises whenever he moves.


[[folder: Live Action TV ]]

* The bomb disposal robots in ''Series/BombPatrolAfghanistan'' are noisier than you would expect of a military gradr machine. Then again, it is designed to be remotely operated an possibly make [[HeroicSacrifice heroic sacrifices]] so the humans won't have to get up close and personal with [=IEDs=].
* The Cybermen in ''Series/DoctorWho''. Lampshaded in one episode when they somehow manage to sneak up on the Doctor and he asks them if they've "got their legs on 'silent'".
* In ''Franchise/StarTrek'', we have Borg drones that make mechanical and electrical noise when moving, or [[YouWillBeAssimilated assimilating]].
* Franchise/{{Robocop}} in [[Series/RoboCopTheSeries the TV series]]. When walking he only made stepping thumps, but moving anything else made mechanical noises.


[[folder: Music ]]

* The robots of SteamPoweredGiraffe let out occasional hydraulic hisses and whirrs, particularly when they start up or power down.


[[folder: Toys ]]

* Most of the ''{{Bionicle}}'' web animations have this for ''all'' the characters, even though they're partly organic and technically not robots. (Including [[FridgeLogic a few who are actually organic beings wearing armour]]). Averted in the DirectToDVD movies, however (save for a handful of instances).


[[folder: Video Games ]]

* Most robotic constructs in ''WorldOfWarcraft'' are rather clanky. Justified because most of them are hostile or potentially attackable [=NPCs=], and all [=NPCs=] have a combat noise. Robots are just noisier than most.
** For a time, having the Lil' Smokey non-combat pet out was a great way to annoy other players due to [[MostAnnoyingSound how noisy the thing was.]]
* There are creaking/squeaking robot enemies in the video games ''VideoGame/BanjoKazooie'' and/or ''Banjo-Tooie''.
* [[{{Cyborg}} The Arachnotrons, Spider Mastermind and the Cyberdemon]] from ''VideoGame/{{Doom}}'' make a hell of a noise when they walk around on their metal legs.
* ''{{Tekken}}'''s Jack-type cyborgs make a satisfying crashing noise when knocked over, although they're quiet when moving.
* The Dwemer Centurions in ''VideoGame/TheElderScrollsIIIMorrowind'' produce a distinct metal-on-stone clacking sounds whenever they are near.
** The Dwemer [[http://elderscrolls.wikia.com/wiki/Animunculi Animunculi]] of [[VideoGame/TheElderScrollsVSkyrim Skyrim]] clank, click and emit steam as they move.
* Omega makes these only in ''[[VideoGame/SonicTheHedgeHog2006 Sonic 2006]]''.
* The various Robot Mercenaries of Grey Mann's army in ''VideoGame/TeamFortress2'''s Mann Vs. Machine mode clatter, sputter, and clank as they move around. [[http://youtu.be/C4cfo0f88Ug?t=2m Most obvious in the trailer video]] but they're still fairly noisy in the game. This is masked somewhat by their tendency to babble constantly.


[[folder: Western Animation ]]

* In ''Franchise/{{Transformers}}'', you sometimes (different series are different on this, and many things) hear sounds as the robots move. ''WesternAnimation/TransformersAnimated'' in particular has fun with it, with high-pitched whirring noises that say 'high tech' for most of them, but the old geezer of a medic, Ratchet, makes much creakier noises.
* {{Subverted}} in ''TheSimpsons'' episode "Lisa's Wedding": we FlashForward to the far future [[IWantMyJetpack (2010)]] and see what we think are a group of robots clanking by, but it's really just several college kids going to ''Film/TheWizardOfOz'' auditions in Tin Man costumes.
