There was a time when this sort of thing was taken seriously.

In comes a Price Club-sized tin can with Slinky arms and legs, looking like the grandfather of Pimpbot 5000, buzzing with a menace that suggests he flunked Asimov 101.
Jim Wright's Star Trek: Voyager review of "Night"

The opposite of those human-looking robots such as the Robot Girl. This is a robot designed with function over form in mind — or at least, designed to look like it is.

Though most historical examples are technically humanoid in form (remember: CG was a new thing back then, and puppets are expensive, so you gotta be able to get a costumed actor to play these machines), they still generally look like a trashcan or boiler with arms, legs (if it even gets those), and a head — either distinct or fused to their torso — pasted onto it. This robot is usually not painted and it's often possible to easily see screw heads holding it together. Bonus points if the robot's arms are made of flexi-tube with pincers at the end.

Nowadays usually done to make the 'bot look amateur-made or old-fashioned, as the unwieldiness such machines (especially those played by costumed actors) displayed on-screen almost completely discredited this trope to modern audiences. However, in older Zeerust, it was often played straight.

    Anime & Manga 
  • Gigantor is a clear example of this. His body exactly resembles a tin can, being perfectly cylindrical (except for his rockets) and made of bare metal, while his arms and legs are similar.
  • Likewise, Mitsuteru Yokoyama's other early Super Robot, Poseidon from Babel II.
  • Mechazawa from Cromartie High School. Despite being shaped like a large tin made of metal and needing to be constantly oiled, he and everyone else is blissfully unaware of his true nature. ...Or at least everyone's afraid to broach the issue with the school's toughest fighter directly.
  • Although Astro Boy himself doesn't count, many robots in his world do.
  • Auta Magetta in Dragon Ball Super sports this look, though various authority figures imply he's not actually a robot but naturally looks this way. Nevertheless, he makes a lot of mechanical sounds as he moves and speaks only in onomatopoeia of those mechanical sounds. As one of Universe 6's strongest fighters, Magetta is seemingly indestructible and has Magma Man powers, but he is very bulky and cannot fly.
  • Zatch Bell! made a toy one out of chopsticks and a Pretznote  box, which he named Vulcan 300.

    Comic Books 
  • Spider-Man:
    • Spider-Man once has to deal with the robot XP-2000, who is really obsolete compared to androids like The Vision and Ultron. Keep in mind that Ultron was designed in the 1970s, and Vision was built by Ultron. This says a lot about XP-2000 being designed obsolete. The original Ultron design was actually pretty in-line with this aesthetic, though.
    • The little flying robots used by Spidey's enemy Armada.
    • Also the cobbled-together robots built by Future Max.
    • Finally there's the silver-age Spider-Man villain The Living Brain, featuring the greatest mechanical mind 1964 could offer.
  • Magnus Robot Fighter: 4000 AD by Gold Key Comics has a future lousy with robot servants, almost all of them of the tin-can-humanoid variety, generally with flexi-tube or armored-cable limbs.
  • The lumbering warbots of Ashley Wood's World War Robot fit this trope to a T.
  • Tin Can Tommy from The Beano doesn't only fit this trope but has a name to match.
  • Reed Richards's little flying HERBIE robots.
  • Elektro from Fin Fang Four.
  • Gyro Gearloose's helper Little Bulb from the Disney Ducks Comic Universe.
  • All versions of COMPUTO from Legion of Super-Heroes.
  • Doctor Doom's purple Mecha-Mooks.
  • X-Men: The Sentinels.
  • The Mad Thinker and the Leader seem to prefer using Organic Technology, but they still sometimes build metal robots, which always come out looking like this.
  • Ironhorse from Astro City is like this, built with a steam locomotive motif.
  • Iron Man: Titanium Man's Powered Armor has this look, resembling a green titanium can with arms, legs, and a computer monitor head bolted on, a result of Soviet engineering being primitive compared to what Iron Man is capable of.

    Comic Strips 
  • The robots in Brewster Rockit: Space Guy! frequently fit this trope, especially Oldbot and the Killbots.
  • In Calvin and Hobbes, Calvin once builds a robot using a tin can for the head. Unfortunately, he doesn't know how to make one that does anything.

    Films — Live-Action 

In General:

By Movie:

    Literature 
  • Norby, of the eponymous series by Isaac Asimov, is shaped like a container for nails, to the point where the protagonist bought him for a song because he looked so non-functional.
  • Norwegian-English author Phillip Newth has written several books about a constantly-malfunctioning domestic servant robot named Matilda, who is described at least once a book as having a body shaped like a tin can and a head shaped like a smaller tin can. Matilda is a bit of an oddity in her books; robots are plentiful but usually look a lot more sophisticated or even just like humans. Matilda looks the way she does (and malfunctions so often) because she's old, "almost an antique."
  • The robots in Andy Bucket's Robots look like this, because Andy made them with tin cans.

    Live-Action TV 
  • The Federation security robot in Blake's 7 which unfortunately was never as menacing as it was supposed to be, given the tendency of its arms to flap up and down as it moved, and the flamethrower that dropped out of its groin region which caused the production crew to dub it "The Flasher". Eventually the poor bot was restricted to a couple of close-up scenes in the early episodes.
  • This is a common monster template in Doctor Who, as they're a relatively easy "obviously non-human but not obviously just a guy in a suit' monster design:
  • Robot, from the Captain Helix Show Within a Show in Hyperdrive; unsurprising, given that it's a parody of Star Wars and cheap imitations of the same.
  • Robot from the original Lost in Space; danger, Will Robinson! Not Robby, but definitely Inspired by... him (though Robby himself appeared as an alien robot in one episode).
  • The robot that Grandpa and Eddie build in The Munsters episode "Tin Can Man" literally had arms and legs built out of tin cans.
  • In Mystery Science Theater 3000, Tom Servo's body is made out of a barrel-shaped piggy bank and a toy car engine block resting on a Halloween "Boo Bowl" base. He has an Eyeless Face and no feet; while the tiny hands on the end of his spring arms are human-shaped, they're quite useless.
  • Power Rangers:
    • Orbus and Klank from Power Rangers Zeo, plus Prince Sprocket and King Mondo himself. This is in contrast to the much less tin can-ish members of the Machine Empire.
    • Toy Org from Power Rangers Wild Force. He resembles a toy robot, yet is one of the Rangers' strongest foes.
  • Andy, the tin box robot on Quark. In the pilot episode, it mistakes a garbage control box for a potential Love Interest.
  • Steampunk, one of the combatants in Robot Combat League, is a nod to this type of robot.
  • Sam the Robot from Sesame Street. This being Sesame Street, of course, he still has googly eyes and a bowtie.
  • In the Shining Time Station episode, "Schemer's Robot", Schemer buys this kind of robot, which he names Robbie, to run his arcade. Robbie keeps talking about food and falls in love with Schemer's jukebox. In the end, Schemer gives Robbie to Barton Winslow to work at his general store when Robbie falls in love with Barton's motorcycle.
  • Portrayed quite literally in The Sifl and Olly Show, where Sifl builds a robot literally made out of a tin can to use as a stand-in host for Olly, until Olly returns and destroys in the middle of it singing the 1980s song "I Know What Boys Like" by The Waitresses.

    Pinball 

    Pro Wrestling 
  • Taken one step further with Kaiju Big Battel's Robox, a mighty robot built from "Indestructible Cardboardium", i.e. a cardboard box with arms, legs, and a robot face built on.

    Radio 
  • Marvin the Paranoid Android from The Hitchhiker's Guide to the Galaxy pretty much consigns himself to this as he's hopelessly taken for granted.
    Marvin: Do you want me to sit in a corner and rust or just fall apart where I'm standing?

    Toys 
  • Robot toys back then were mostly made of tins before the use of ABS and PVC plastics were common, making them the potential Trope Codifier. Back in post-WWI era, Japan and Germany were the primary manufacturers of tin toys, which are inexpensive and easy to create through mass production. While World War II halted the production of tin toys in Japan and Germany, it underwent a resurgence when the U.S. toy companies began outsourcing tin toy production to Japan after the war. Japanese toy manufacturers then started to innovate new tin toy designs by creating battery-powered and even remote-controlled toy robots. Nowadays, tin toy robots have become obsolete due to the use of cheaper materials such as ABS and PVC plastics becoming more prominent. However, this turned tin toy robots into valuable collector's items, and Metal House, the sole surviving tin robot manufacturer in Tokyo, is still manufacturing tin robots today.
  • This replica of Robby The Robot.
  • The Mr. Atomic Robot, as manufactured by Yonezawa (The predecessor of Tomy and subsequently TakaraTomy) and distributed by Cragstan in 1962, is an egg-shaped tin robot which moves while wiggling its legs, and it has headlights which changes colour.
  • The TinBot is a series of robot toys developed in Hong Kong, with a literal tin can as its body for the magnetic head and limbs to attach onto. All of the parts can be stored in the said tin can.

    Tabletop Games 
  • Isaac Asimov's Robots: The Sammy-type robot looks like someone is wearing a barrel over their body and flexitubes over their arms. Their fishbowl-like heads have a permanent smiley-face etched onto them, unlike their more realistic counterparts of Giskard or Daneel's design.
  • Paranoia: Jackobots (from "jack of all trades") are intended to be able to do the same physical things as humans, so they're basically humanoid in size and shape, but clearly mechanical. Other bots range from sorta humanoid (docbots, scrubots) to Sapient Ships (warbots, flybots).
  • Ancient Martian Robomen in Rocket Age can be sleek and graceful, but many of the non-service models were built with practicality and survivability in mind.
  • Combat, Janitorial and Animal Care robots in the Classic Traveller adventure Research Station Gamma.
  • Warhammer 40,000 :
    • The Orks have Mini-Mecha (with an Ork welded inside) aptly known as Killa Kanz. Their Humongous Mecha are built to a similar design.
    • The Tau attack drones that look like flying trash lids.

    Video Games 
  • Amazon: Guardians of Eden: B.O.B. looks like two trash cans with added feet and will actually think you're also B.O.B. if you put a trashcan on your head. He was made in the 1950s, after all.
  • The final boss in Balloon Kid is this kind of robot.
  • Borderlands:
    • The Atlas drones from the Secret Armory of General Knoxx DLC.
    • Most of the Hyperion bots from Borderlands 2. Claptraps would be an example if not for all the personality, though it's basically a chippy and personable UI wrapper built around a sociopathic core.
  • Malco, one of the control room guardians from Cave Story, is one.
  • The Robobrains from Fallout fit the bill, unusually having glass domes filled with a living brain for heads and very heavily resembling The Robot from Lost in Space. The Protectron models, meanwhile, look suspiciously like Robbie the Robot from Forbidden Planet. The Synths in Fallout 4 notably avert this by being distinctly humanoid, especially 3rd Generation Synths, which are nearly completely identical to humans in almost every way. Because A.I. Is a Crapshoot, this is a point of major contention for Wastelanders, who are used to dealing with the obviously artificial tin-can robots of the previous games.
  • Cronk and Zephyr, elderly Warbots who first appear in Ratchet & Clank Future: Tools of Destruction.
  • Metal Slug 3:
    • The Mars Robot in the final stage is one, they are intended to be expy of the Daleks, for being both Cyborg and this trope.
    • Also the giant blocky toy robot that's the end-boss of the factory level.
  • Robots from Machinarium are very much like that, especially the main character.
  • ION of Phoning Home has a cylindrical torso.
  • Total Annihilation has a model of robot which is actually called "The Can". It's pretty much a big metal box on legs, with a turret on top.
  • The Gearmos in the Super Mario Galaxy games.
  • Super Robot Thursday from Disgaea: Hour of Darkness fits this trope, as he, Captain Gordon, Defender of Earth!, and Jennifer are parodies of early science fiction series.
  • Oddworld's "Greeters" are a very literal version of the laconic, and resemble nothing so much as "a hot water heater on a unicycle." They're also the in-universe Stepford Smilers.
  • Scrap Garden has the appropriately-named Canny. He basically looks like a can with arms and legs.
  • Sonic the Hedgehog has many, such as E-123 Omega.
  • Metroid:
    • Super Metroid features these in the Wrecked Ship. They were round cylinders with legs and no arms.
    • The Tinbots, defenders of the Steampunk planet Elysia in Metroid Prime 3: Corruption, are exactly that; easily blown apart and even more easily melted once the Plasma Beam is acquired. The Steambots and Steamlord are less fragile.
  • Tears to Tiara 2 has Talos like the first game. We get one on our team called Calcos.
  • In The Deadly Tower of Monsters one of the three player characters is an old fashioned robot known simply as "The Robot."
  • Custom Robo on the Gamecube features the Oil Can Robo, a clunky, weak, slow Joke Character built from old steel drums, tin cans, and lead pipes. It's basically a rusty and barely humanoid mess, useful only for a Self-Imposed Challenge or Cherry Tapping an opponent.
  • The Roboids from the Future world of Cratermaze, complete with pincer hands.
  • The titular robot of Alien 8 resembles a flip-top rubbish bin with feet.
  • The Kohbu(/Eisenkleider/STARs/etc.) from the Sakura Wars series are trashcan-looking Humongous Mecha.
  • Mettaton in Undertale is described aptly as a "sexy rectangle"; despite looking like a vending machine on a unicycle with Trollface "shloopy" arms, he's considered Mr. Fanservice in-universe. Amusingly, he implies on the Kill 'Em All path that he considers this form more attractive than his Pretty Boy EX and NEO forms.
  • Xenoblade Chronicles 2: Poppi's initial form is like this (apart from the face). Later on she receives some upgrades that take her into Ridiculously Human Robot territory.
  • Funk Unplugged: Ampy has a friend who is a floating tin can.

    Visual Novels 

    Web Animation 
  • Homestar Runner: The Cheat Bot is not a real robot (being The Cheat with a metal can on top), but would be a perfect example if he were. The visor robot is a better example; in fact, most robots in the series would qualify, down to the Grape Nuts Robot (a "robot" made out of some LEDS and a Speak & Spell shoved inside a box of cereal with a slinky for an arm).

    Webcomics 

    Web Videos 

    Western Animation 
  • Transformers Animated has literal Trashcan Robots that transport all of Detroit's waste.
  • B.O.T. from the infamous G1 Transformers episode of the same name.
  • Hovering medibot MC Rubbish from Wave Twisters, with a cylindrical limbless body and a spherical head topped by a red pith helmet. (His names—"Rubbish" and "Thrashcan"—in fact are a Lampshade Hanging of his shape.)
  • Futurama:
    • All bending units are perfect caricatures of 1950s-style movie-robots, with tin-can (and cocktail shaker) bodies, flexi-hose arms and legs, typical robot heads, and eyes clearly lifted from Crow T. Robot.
    • Fry encounters an actual trash can who also happens to be a self-aware robot.
  • There are several robots in the Looney Tunes/Merrie Melodies series like this — for instance, in "Robot Rabbit" and "Lighter Than Hare." (In the latter, Bugs Bunny even uses the robot as a trash can.)
  • Rosie the robot maid from The Jetsons. (There was also a male robot called Mac, made by Henry, the building janitor.)
  • The Master Cylinder, from Felix the Cat.
  • The Underdog short "March of the Monsters" had these, but it was never stated who the robots' master was.
  • The Fleischer Superman series featured "The Mechanical Monsters", used by the inventor for a series of robberies.
  • In an episode of The Simpsons, Homer builds one of these out of a mailbox for Bart to enter in a Robot Wars-style TV show. Justified in that Homer was secretly working it from inside, having realized he had not the faintest idea how to actually build a robot. When it doesn't work, he instead wears it like armor and pretends to be a robot.
  • XJ-8 from My Life as a Teenage Robot. In comparison, her predecessors are mostly Starfish Robots, and her successor is a more streamlined fembot.
  • NEPTR from Adventure Time literally has a tin can Finn meant to be his "head" and drew a face on. When a lightning bolt brought it to life, its actual face ended up being elsewhere and the can-head is purely ornamental.
  • H.E.L.P.E.R. from The Venture Bros., the epitome of the robot buddy as seen by pop culture in the 1950s. True to the spirit of the show, he was apparently actually built in the 50's and was described as "geriatric" and "senile".
  • In Samurai Jack, the earliest robots built for Aku looked like they were made of scrap parts, including tin cans. They weren't very reliable and could only move about for a few seconds before breaking down. They were not sentient, however, so there was no worry about it—the roboticists just went back and designed better robots. By the time Jack arrives in the Bad Future, automatons had become advanced enough that the only ones that didn't pass off as Ridiculously Human Robots were designed intentionally to be robot-like (some of whom also intentionally invoke Tin Can Robot style, such as Extor's wicker basket robots).
  • The Super Robot of Super Robot Monkey Team Hyperforce Go! has boxes for its head, body, and feet, extremely boxy hands and fingers, and tube arms. A late-series episode showed him to be the first in a line of several robots, with the most recent being a much sleeker and human-sized Robot Kid.
