[[caption-width-right:346:This trope is easy for metalbenders.]]

-> ''"Fresh and ready for battle, I released the first steam valve and locked in the marionette-like motion activators.\\
Every movement of my body caused the Golem to react in like manner. I stomped across the battlefield, and struck the rock giant in the chest.\\
It grabbed me. I half expected the whole contraption to explode, but the golem stood solid.\\
I pushed back, grappling hand to hand with the creature! Imagine! Me, a simple engineer, locked in melee with a legend!"''
-->-- From the description of the {{Golem}} unit, ''VideoGame/AgeOfWonders3''

A type of control system for HumongousMecha, where the robot reads your movement like motion captures. This entails the user doing a movement, like miming walking forward or throwing a punch in the cockpit, and then this action is mirrored by the Mecha doing the same thing. This control interface is often used as a justification of the humanoid shape because it has more natural and graceful movement than one without the humanoid shape using the same system. Doing this justifies the mecha as an ImpossiblyGracefulGiant.

This usually comes in two flavours, free control cockpit room inside the mecha (or remote controlled by same) or a large apparatus that the pilot fits into. The first type of control have the pilot wearing some kind of motion capture suit, or the room itself has a certain motion capture technology, and the mecha simply mimics it. The second type usually have a mechanized suit, or part of one, inside the cockpit, which is used to capture the motion ''and'' hold the pilot in place.

Both types, however, usually need some kind of secondary input device (voice activation, thought control, computer assisted action module, traditional keyboard, etc.) to compensate for anything non-human in the mecha, like propulsion, integrated weapons, etc. Both variants can be done through remote control technology.

PoweredArmor or MiniMecha may also use the second type to read the operator movement; this is closer to the "hard" end of the MohsScaleOfScienceFictionHardness.



[[folder:Anime and Manga]]
* [[MiniMecha Landmates]] in ''Manga/{{Appleseed}}'' move their arms and legs like this: The thighs/upper legs are oversized to fit the operator's legs, while their arms fit in a pair of small "Master" arms in the mech's chest, which the larger "Slave" arms copy the movements of.
** Similar mechs appear in ''Anime/GhostInTheShellStandAloneComplex'' (also by Shirow Masamune).
* A magical variant in ''Manga/{{Bleach}}''. Captain Sajin Komamura's [[SuperMode Bankai]] summons a [[AttackOfThe50FootWhatever colossal]] samurai golem, wielding an [[{{BFS}} appropriately sized sword]]. The giant matches Komamura's movements, so a single swipe on Komamura's scale translates into a crushing blow from the giant that can easily demolish ''buildings''. His Shikai state does something similar, but with only one body part at a time.
* ''Anime/{{Daimos}}'' is the very 1st one to have this in Anime, despite Kazuya sitting on the cockpit, only the arm movements are copied, but how does the leg movements get copied too?
* ''Anime/GaoGaiGar'': This is how the eponymous mecha is controlled whenever Guy performs fusion with Galeon, who transform into a humanoid figure of Guy, and he stands within.
* ''Anime/GunXSword'': Priscilla's Brownie is the only one like this on the series. However, it's made clear that the system she uses isn't new, it's just that most people don't have the dexterity to pull it off.
* ''Anime/GunBuster'': This trope describes the way the titular HumongousMecha (and the mass-produced Sizzler units descended from it) are controlled, with girls sitting/standing on a really thin rod and using arm and leg servos. The Gunbuster itself also has a GuyInBack who controls the weapons with a keyboard.
* ''Anime/MobileFighterGGundam'': Called the Mobile Trace System, the pilot stands on a platform and wears a tight rubber suit which controls all the movements so it can function as a kung fu mecha. Special attacks are voice activated. This is different from other mecha in the ''Franchise/{{Gundam}}'' 'verse, which generally have nothing but two joysticks and two pedals.
** In ''Anime/SDGundamForce'', the SealedEvilInACan Musha Daishinshou is one as well. Given that the entire country of Ark and its people is one big send-off to ''[[Anime/MobileFighterGGundam G-Gundam]]'', this shouldn't be surprising. Of course, unlike most Mechas on this page, Daishinshou seems to be partially sentient, as shown when it struggles against its binds. Luckily, when someone is in the cockpit, Daishinshou is totally under control.
* ''Anime/MazingerZ'': The SuperRobotGenre TropeMaker showed a primitive form of this. Although Kouji used a pair of joysticks and an array of buttons, levers and pedals to move Mazinger-Z, often Mazinger mirrored his motions inside the cockpit and vice versa (one example happened in an episode where a {{Robeast}} burrowed into the ground to try to escape. Mazinger-Z grabbed the Mechanical Beast's legs and leaned his body and head backwards as it struggled to pull the Mechanical Beast out of the ground. Inside the cockpit, Kouji was in the exact same position, doing the exact same thing).
* ''Anime/TheVisionOfEscaflowne'': Piloting a Guymelef was done by moving inside a special harness placed within the chest.
* The Nirvash's final form in ''Anime/EurekaSeven'' mimics the pilot's movements. It even helpfully levitates them while flying.
* The Mashin of ''Manga/MagicKnightRayearth'' operate in this manner, wielding scaled-up versions of the trio's Escudo swords and reflecting their injuries back on them, although the Mashin are more specifically guardian gods that take the ''form'' of giant mechs rather than being actual mechanical devices.
* {{Downplayed}} in ''Anime/GaikingLegendOfDaikuMaryu''. The Power Glove feature of Gaiking allows it to mimic its pilot's hand and arm movements, but nothing else.
* ''Anime/StarDriver'' has this for Cybodies, though originally only the [[TheChosenOne Ginga Bishonen]] Takuto had the magic sphere which allowed that. Come the second seal being undone and only those able to truly wield their Cybodies through their Marks are fighting.
* ''Anime/SuperDimensionCavalrySouthernCross'' mixes this with virtual reality with the Bioroids. The nerve impulses of the pilot are redirected to cause the Bioroid to move instead of the pilot's body. It's assumed that a similar method of force-feedback is also involved.
* Team Rocket, who routinely use HumongousMecha in the ''{{Anime/Pokemon}}'' anime, used a couple of Meowth-themed versions of these in the ''Sun and Moon'' series. It's usually the one way [[NonActionGuy Meowth]] manages to be a halfway dangerous battler against the heroes.

[[folder:Comic Books]]
* In ''Comicbook/TheIncredibleHulk'' #275 a new villain named Blackbird breaks into Gamma Base and finds a bunch of discarded, never-used weapons. She's there at the behest of her employer ([[spoiler: the Leader]]) but can't resist using a Motion Capture Mecha called Megalith which uses brainwaves to move against the Hulk. Turns out there's a reason it's been scrapped without being used: there's mental feedback so that any damage infliced on the mecha is felt by the operator. Oh, and the Hulk bashes it to pieces.
* Hisako "Armor" Ichiki, from the ''Comicbook/XMen'', controls her eponymous armor like this. It's a psychic construct, so there's no control interface as such, but Hisako can be seen floating inside the armor as it mimics her movements, and the armor itself is designed to invoke a humanoid mech.

[[folder:Films -- Animated]]
* ''WesternAnimation/{{Megamind}}'': Megamind's giant robot has a huge open cockpit with his "Black Mamba" costume doubling as a mocap suit.
* This is how the giant Reptar robot works in ''WesternAnimation/RugratsInParis.'' Chuckie eventually takes control of it, leading to a scene where the robot scratches its butt as Chuckie tries to yank a wedgie out of his shorts. Later on he uses it to beat another giant robot by imitating a Jackie Chan movie he saw on an airplane.

[[folder:Films -- Live-Action]]
* The [[MiniMecha AMP suits]] in ''{{Film/Avatar}}'' work this way, most noticeably when Quaritch is first seen piloting one. He points at Jake; the suit does the same. The arms, hands and upper body are controlled directly from the driver's, including giving feedback against the limbs to represent resistance encountered. Walking and other movements are controlled partly via footpedals though - it is said that while it is very easy to learn the basics, operations such as getting up from a prone position take a lot more practice.
* Appears in the film ''Film/RealSteel.'' While most robots are remote-controlled (or voice operated), Atom is equipped with a program called "Shadow Mode," which allows him to perfectly mimic a person's movement. Mostly this is used to pre-program moves used on command, but [[spoiler:Charlie later uses the Shadow Mode to help Atom fight against World Robot Boxing champion Zeus when the former's voice command receptor is damaged.]]
* ''Film/RobotJox'' features giant robots whose pilots' movements are mimicked by the robots, thanks to their special suits.
* The Jaegers in ''Film/PacificRim'' exhibit an unusual version of this, with two pilots working in tandem to control the mechas. A [[MentalFusion neural bridge]] is necessary to reduce the mental strain of piloting a Jaegar, while leg and arm apparatuses on each pilot are used to translate the pilots' motions into the Jaegar's motions.
* The third ''Film/SpyKids'' movie has a giant robot that Juni Cortez has to use against [[spoiler: Demetra]] in an arena match; by the use of a special suit, and moving in place on an open platform. Any movements by him are mirrored by the robot, although Juni doesn't get used to it right away.

* In Creator/StanislawLem's ''Fiasko'', the Diglators are controlled like this. It briefly backfires when the pilot reaches to scratch his nose and ends up smashing his head projector.
* ''Literature/{{Domina}}'': America has "echoes," [[MiniMecha mini-mechs]] that mirror the pilot's movements. They're not seen often, but when they are, they are used to justify InstantExpert and FallingIntoTheCockpit, since in theory piloting one is the same as fighting normally.

[[folder:Live-Action TV]]
* ''Franchise/SuperSentai'' / ''Franchise/PowerRangers''
** ''Series/GoseiSentaiDairanger'': Ryuuseioh, being one of the lightest Sentai mecha ever, follows Ryu Ranger's movements. Even better, it's apparently the face actor in the Ryu Ranger suit for these scenes (and visibly fills the suit out differently). This didn't translate into Season 2 of ''Series/MightyMorphinPowerRangers'', though, as while Ryuuseioh was carried over (as the Red Dragon Thunderzord) the Ryu Ranger footage was not. However, ''MMPR'' did show Tommy switching the Tigerzord into a mocap mode.
** In ''Mighty Morphin''' Season 3, the Aquitian Rangers’ Battle Borgs were controlled via psychic link, so the Rangers on the ground would perform moves that would be copied exactly by their machines. Of course, the machine getting hit meant [[{{Synchronization}} you did too.]]
** In ''Series/MiraiSentaiTimeranger'', Gien's ultimate robot, [=NeoCrisis=], could plugged directly into Gien, allowing the two to synch perfectly.
** ''Series/JukenSentaiGekiranger'' and ''Series/PowerRangersJungleFury'' had the mecha copy the moves of Rangers who exist in a "cockpit" that has no controls. Notably, [=GekiTohja=] and [=GekiFire=]/the Jungle Pride and Jungle Master Megazords require the movement of three pilots in unison.
** ''Series/ZyudenSentaiKyoryuger'' and ''Series/PowerRangersDinoCharge'' has a setup similar to ''Gekiranger''.
* ''Series/TomicaHeroRescueFire'' has X Dragon Robo. It actually has its own AI and can fight well enough on its own, but it goes into mo-cap mode when doing its [[FinishingMove Final Rescue]]. Its combination with Fire Dragon, Rescue King, actually is piloted by Fire-1 X, and is a true mo-cap mecha.
* ''Series/RobotCombatLeague'' is all about these fighting each other. They allow for an impressive array of moves, with parries and such.

* Not a mech, but the spacehship ''The Kestrel'' from ''Podcast/{{Jemjammer}}'' is piloted by a person plugging themselves into the ship's helm and maneuvering it with their arm gestures. It makes drinking a glass of water during somewhat difficult.

[[folder: Tabletop games]]
* ''TabletopGame/BattleTech'' has a limited example of this. The pilot controls the mech using two to three joysticks, a throttle lever, two to four pedals, and a [[CoolHelmet Neurohelmet]].[[note]]A limited BrainComputerInterface which is used by the 'mech's motion computer to gauge pilot intent in maintaing balance, and also to give a kinesthetic feedback on the 'mech to the pilot to aid in such.[[/note]] Melee combat is normally accomplished by aiming at a nearby enemy and hitting the "punch" button to let the computer sort it all out, but some mechs are equipped with a waldo which the pilot sticks his hand in to control the mech's arm, for for more finesse - a battlemech is unlikely to have one, but a [=IndustrialMech=] probably has one. [[PoweredArmor BattleArmor]] uses hand signals to control its weapons; to fire the built-in lasers, one must point their index and middle finger forwards, clasp their ring and little finger to their palm, and then cover them with their thumb in order to fire. The rest of the battlearmor is controlled by servo-motors to assist the soldier's movement, or by eyesight to trigger heads-up-display elements. While [[MiniMecha Protomechs]] are too small for a full cockpit so pilots need to use their neurohelmet and [[BrainComputerInterface enhanced imaging]] exclusively to operate it.

[[folder:Video Game]]
* The "Direct Motion Link" System in the Dygenguard from ''VideoGame/SuperRobotWarsAlpha''. As a ShoutOut to ''G Gundam'' and its Mobile Trace System, a pilot stands using a harness-like device to control the mecha through body motions, mimcing their movements inside the cockpit. This is perfect for the Dygenguard's {{Samurai}} pilot [[Characters/SuperRobotWarsAlpha Sanger Zonvolt]], who uses a sword hilt in the cockpit to replicate his sword techniques.
** When ''VideoGame/SuperRobotWarsOriginalGeneration'': ''[[AnimeOfTheGame Divine Wars]]'' was released, the Valsione belonging to [[Characters/MasouKishin Lune Zoldark]] reveals a similiar, but earlier design of the Direct Motion Link System. In the Valsione's case, the system also mimics the pilot's face, since the machine is really a giant RobotGirl of sorts.
** The Soulgain and Zweizergain from ''VideoGame/SuperRobotWarsAdvance'', revealed via ''The Inspectors'' AnimatedAdaptation, also uses an off-shoot of the Direct Motion Link System, but is instead known as the "Direct Feedback" System. While mimicing its pilot's movements, it also allows the pilot to execute KiAttacks through a build-up of emotions.
** At least in the [[AllThereInTheManual supplemental materials]], all Shura Gods from ''VideoGame/SuperRobotWarsCompact3'' uses an unnamed system that looks similar to the Direct Motion Link System. Regardless, this trope fits for Shura characters, since they're all martial art practicioners.
** Uniquely done in ''Super Robot Wars Alpha 3'' with the [=RaiOh=]. After its pilot [[Characters/SuperRobotWarsAlpha Touma Kanou]] was driven BrainwashedAndCrazy due to the flawed LIOH System overpumping adrenaline into him, the Alpha Numbers deem the LIOH system too dangerous, swapping it out with the Direct Motion Link System. Touma, who knows bits of karate, is forced into TrainingFromHell by his peers to effectively use the system and its advantages. This culminates in one event where his mastery of using this trope essentially destroys any need for the LIOH System when he requests his allies putting it back into the machine.
* In ''VideoGame/ArmoredCore'', the titular Cores are implied to be this, since their non-modular predecessor units are called MT's (short for Muscle Tracer). How this is supposed to work for non-bipedal AC's[[note]](like reverse-joint, quadrupedal, treaded, or hover types)[[/note]] remains to be seen. [=NEXTs=] in ''[=AC4=]'' and ''for Answer'' take this one step further with a direct neural link between the mech and pilot.
* ''VideoGame/MetalFatigue's'' giant Combots are controlled by a group of four, with the main pilot using this method to do all the major controls like moving and attacking. The rest of the squad then manages things like engines and orther systems.
* Omnigears in ''VideoGame/{{Xenogears}}'' don't even require motion. They respond entirely to mental commands (you picture the robot moving in your head and the actual robot mimics this) and the cockpit it otherwise empty aside from a seat for the pilot to sit in. This is justified by them being essentially magic, created by an individual in possession of a Gear approaching one of several ancient artifacts and being "compatible" with it, which will promptly bond with the Gear. This new Omnigear will only respond for this person or their direct decendents. This doesn't seem to stop people with regular Gears from making them replicate their own complicated martial arts techniques using regular control sticks.
* ''VideoGame/XenobladeChroniclesX'': Alien-made Skells are shown to use a system like this: they stand up in the cockpit and it responds to their movements, with holographic rings surrounding their limbs. Human-made Skells are less advanced and use a levers and foot pedals arrangement, though despite this they seem just as mobile and dextrous as the alien ones.
* The titular machines in ''VideoGame/TitanFall'' seem to partly use this trope; the Militia's opening for the first campaign level (revealed in [[https://www.youtube.com/watch?v=z5sqPxbLmIU this trailer]]) show an AI Pilot giving orders to the ground troops from inside his Titan, with the cockpit open while the Titan mimics his hand gestures, suggesting that a Titan's upper body is controlled through motion capture. But this is all we really get to see of their control system so there's no indication on how they control the lower body. They could use the same control system as the suits from Avatar, mentioned up in the Film examples.
* ''Videogame/EndlessLegend'' has motion capture cavalry. The Cultists Of the Eternal End's cavalry unit, the Fanatic, is a horse-sized Endless quadrupedal robot which has its movements synchronized to a Cultist standing on top - the Cultist raises its arms and drops them to set the Fanatic's power source in motion, and swipes down with its hands to make the Fanatic strike with its legs.
* A variation in ''VideoGame/OneMustFall2097'' that crosses over with BrainUploading: pilots in that game are 'chemically linked' to their robots. Instead of being ''in'' the machines, they are controlling it by remote of a sort. The neurons that would normally control movement in their own human bodies are instead linked to controls for the robot, such that the experience is less like piloting the machine and more akin becoming it. However, pilots do not copy nor transfer their minds to the robots; their brains are still in their own heads, and any breakage of the link between pilot and machine apparently snaps their awareness back to their body.
* ''VideoGame/NintendoLabo'': the Robot Kit set allows players to build a back-mounted apparatus that allows them to control the in-game mecha with their own bodies.

[[folder: Web Original]]
* The eponymous ''Literature/IlivaisX'' has the pilot suspended from retractable cables on all four limbs, which also detect the wearer's movements. This is also aided by a thought control system that involves projecting one's soul into the machine. The other Ilivais units made by the Gaia Forces (aside from the Sho) are outfitted with this same system.
* [=LIMBs=] in ''Webcomic/MyLifeAtWar'' have a single arm controlled by the pilot using a gauntlet on their right arm, leaving them free to operate secondary controls with their left.

[[folder:Western Animation]]
* ''WesternAnimation/MegasXLR'': One of the various alternate modes of control of Coop's giant robot which resembles a DDR dance pad with gloves. Given how incredibly out-of-shape Coop is and it being unable to use any of MEGAS's weapons but its arms and legs, it doesn't work for long, which is probably why Coop made it the backup control system. It does manage to work well enough to buy Kiva time to fix the primary system.
* The second half of ''WesternAnimation/BatmanBeyond's'' pilot episode had a lifting arm operated by a guy in the cockpit wearing a two-fingered mechanical glove. The HumongousMecha Willy Watt takes over later in the season straddles the line between this and thought-control: the normal version is pure mo-cap, but after Willy is mentally linked to it, it does a lot more than Willy's equivalent motion.
* In the ''WesternAnimation/{{Futurama}}'' episode "Raging Bender," Bender fights an Ultimate Robot Fighter many times his size, who is controlled by Phnog, Leela's old martial arts teacher, whom she hates. When Leela realizes that Phnog is controlling the robot directly, she fights him, and gets him to punch himself, using the robot's fist... knocking himself (and the robot) out.
* In ''WesternAnimation/PinkyAndTheBrain'', while Brain's robot suit is controlled by levers that always seem to stick, [[EvilGenius Snowball's]] robot suit is controlled through motion capture. The suits may not seem giant, but they are to the mouse and hamster controlling them.
* Parodied in the ''WesternAnimation/GravityFalls'' episode "Gideon Rises", where Li'l Gideon controls one of these while wearing an ''actual'' mo-cap suit, complete with ping-pong ball sensors.
* The first episode of ''[[WesternAnimation/TotalDrama Total Drama Action]]'' had the cast dealing with a giant monster mecha controlled by Chef. When Chef tried to have the machine grab Owen, he was too heavy to lift and Chef hurt his arm.
* Upper body movement of the Colossus is controlled by [[ArcVillain Kuvira]] in the finale of ''WesternAnimation/TheLegendOfKorra''. There is fine enough mocap control that she can manipulate the hands, as the trope image shows.

[[folder:Real Life]]
* A Japanese four legged robot that was developed to work in nuclear power plants or any other hazardous environment, subverts this. Its motions are computer generated, yet a assisted control personnel can put on two four fingered motion capture controls and assist in its hand and finger motions.
* The [[http://en.m.wikipedia.org/wiki/Robonaut Robonaut]] series of space robots are designed to enable quick space-walks and repairs aboard the ISS via telepresence.
* The Korean [[http://www.theage.com.au/technology/sci-tech/yours-for-christmas-2017-price-11m-giant-walking-robot-that-you-sit-inside-20161228-gtipbe.html Method-2 prototype]], notable for being the first truly bipedal, rather than wheel-assisted, manned vehicle, is uncannily similar to the above mentioned [[Film/{{Avatar}} AMP suits]], including the control method for arms.
