Maybe it's a protocol droid hardwired to be neurotic. Maybe it's a malfunctioning AI who happens to do a mean Shemp. Maybe it's got a few screws loose. However it happened, it's Exactly What It Says on the Tin (no pun intended).
In works of fiction, a robot can serve as comedy relief because of its basic inability to understand humanity, often Comically Missing the Point or taking things too literally. These fundamental misunderstandings can poke fun at the general incomprehensible nature of human interaction in the way only a true outsider can . . . or maybe it's just the funny voice, the clunky walk, or the random gizmos they can sometimes produce. Humor can also soften the risk of a Ridiculously Human Robot descending into the Uncanny Valley.
- R Ichirou Tanaka from the manga and OVA Kyuukyoku Choujin R. He is a robot (or rather, an android) fifteen-year old boy attending a high school alongside human teens. He only eats rice, is rather Literal-Minded, and tends to turn his head around 180 degrees, take off his body parts or get off his bicycle without stopping it first. His backstory is a homage to Astro Boy.
- Nono, the robotic Sidekick Creature Nuisance from Ulysses 31.
- In the original series, roughly half of Yugi's deck (when Yami isn't helping him) consists of Cute Machines and funny robots, the most popular ones among players being the three Gadgets.
- Sho's monsters in Yu-Gi-Oh! GX were called Vehicroids, a bunch of goofy toy vehicles from tricycles to bullet trains to space shuttles. All are downright adorable and good for a chuckle... Just don't underestimate them.
- They never appeared in the anime, but the Wind-Ups while not Machines (most of them) were an archetype of monsters that you couldn't help but find humor potential in. (Unless you were a victim of the Wind-Up Loop which fortunately, can no longer be done.)
- Yu-Gi-Oh! ZEXAL
- Orbital 7, Kaito's Robot Buddy in doesn't intend to be funny, but he often winds up the comic relief anyway, becoming a Butt-Monkey more often than not. (For example, when he switches to "combat mode", he's a clumsy fighter, getting the drills he uses as weapons jammed and winding up in embarrassing situations more often than not.)
- The Obots are Cute Machines designed to pick up garbage, and are used for comic relief, until the season one finale where Mr. Hartland uses them as Mecha-Mooks.
- Full Metal Panic! winds up turning a Humongous Mecha into one after the Arbalest's system AI (designated AL) begins developing sentience. Concluding that Sousuke would be able to more reliably activate the finicky Lambda Driver if he could just chill the hell out, AL starts engaging in Casual Danger Dialogue and Deadpan Snark during lulls in battle. Sousuke thinks this is both nonsensical and annoying, but his marked improvement with using the Lambda Driver following this development suggests AL has a point.
- X-Men villain Mojo has an android named Major Domo as his right-hand-man (plus his accountant and attorney); Major Domo, while loyal, has a sarcastic wit, and is likely the only one who can get away with criticizing his boss (mostly because Mojo is often too preoccupied to notice). Also, Major Domo has a female android as an assistant called Minor Domo; a fast-talking, cheering supporter of Mojo's schemes, she tends to be over-exuberant and excitable, so much that she often short circuits from excitement, literally. (Fortunately, she can be restarted quickly via a button on the back of her neck.)
- In Bloom County in 1984, Oliver Wendell Holmes received a Banana Junior 6000 (a parody of the Macintosh, that debuted the same year) for Christmas; it quickly proved able to talk, and had legs. It was a rude, obnoxious wiseass who would "worship" the television and contemplate its existence (badly). It was usually Oliver's hacking partner (only confiscated by the FBI twice) until 1985 when he deemed it obsolete, mostly because of the bankruptcy of the Banana Computer Company (which only sold two units, including Oliver's).
- More like a "Funny AI System" than a Funny Robot, but Garfield's frequent nemesis is his talking bathroom scale, a Deadpan Snarker who constantly makes fun of his weight.
- Robbie the Robot from Forbidden Planet was likely the Ur-Example of this Trope and probably Robot Buddy too. The equivalent of Ariel (seeing as the movie is believed to have been loosely based on Shakespeare's The Tempest) Robbie was one of the first robots in cinema to have a personality of his own, and he was somewhat of a Deadpan Snarker too.
- Johnny 5 of the Short Circuit films is a malfunctioning A.I. who reprograms himself in large part by watching late-night television.
- R2D2 and C3PO from Star Wars are likely to be Trope Codifiers. C3PO is somewhat more funny than R2, but they both have a lot of comic relief moments.
- Skids and Mudflap from Transformers are two bumbling jiving-talking robots. They're characterized by their cowardice and stupidity in contrast to the other heroic Autobots. Their faces in robot mode look like early 20th century portrayal of African-Americans — buck teeth, bulging eyes, and large ears. One of them has a gold tooth. They bust out ghetto slang constantly, and even threaten to "pop a cap" in someone's ass.
- The Hitch Hikers Guide To The Galaxy has two examples. There is Marvin, the robot who is programmed to constantly sound sad (voiced by Alan Rickman, RIP) and the ship's navigation bot which is constantly cheerful. The funny part comes in because the robots keep their characteristic sound even when the words they are saying make no sense that way. This isn't just about intonation either, the ship's navigator constantly says things like "good news everyone, the missile is headed for us in 10, 9, 8.." Marvin meanwhile says things like "oh no, look at this beautiful sunset". The interactions between the two robots are even more silly for this reason.
- General Tik-Tok from the Oz books, a helpful a clockwork man and Robot Buddy to the other characters. Usually he's very serious, but he can be very funny when his brain winds down before his voice and movements do; without any actual thinking to govern it, he wanders aimlessly and blabbers nonsensically until someone winds up his thought mechanism.
- Twiki from Buck Rogers in the 25th Century was likely cast with comic relief in mind. In fact, even though he can pilot a fighter jet and pick locks, the fact that he can put a smile on the face of almost every member of the overly serious cast (something Buck can rarely do) makes his sense of humor his most valuable trait.
- Doctor Who:
Gadget: Gadget Gadget.
- K9. Originally from classic and eventually spinning off to his own short-lived series, K9 was plucky, brave, and well-nigh indestructible — a combination that made him both adorable and frequently hilarious.
- In "The Waters of Mars", the Doctor makes it clear he doesn't like funny robots. He does later say that dogs are different.
The Doctor: Does it have to keep saying that?
Roman Groom: I think it's funny.
The Doctor: I hate funny robots.
The Doctor: I hate robots. Did I say?
Roman: Yeah, and he's not too fond of you. What's wrong with robots?
The Doctor: It's not the robots, it's the people. Dressing them up and giving them silly voices, like you're reducing them.
- On Get Smart Hymie had No Sense of Humor but was a great source of laughs for being too Literal-Minded and not knowing his own strength. For more yucks, he tended to malfunction a lot too.
- The Robot from Lost in Space often filled this role. He may have only frantically shouted "Danger, Will Robinson!" once, (in ("The Deadliest of the Species", and the word "danger" was only said once) but it had a lot of other moments, often in his attempts to be serious.
- Alpha 5 from the original Mighty Morphin' Power Rangers (and later Power Rangers Zeo) was more often than not comic relief for the team. ("Aye-yi-yi-yi-yi!")
- Crow was no-doubt the funniest character on Mystery Science Theater 3000. The biggest Deadpan Snarker in a cast full of them, and when Hilarity Ensues, he's likely the one who started it.
- Data of Star Trek: The Next Generation is, sadly, not programmed with a sense of humor, which doesn't stop him from often being the funniest character on the show.
- The members of the band Steam Powered Giraffe play as robots onstage. They frequently break into comedy routines between songs.
- Transformers: BotBots is a whole line of them. They are mundane items, like food and sports equipment, that were turned into robots and get into wacky adventures in the mall they live in.
- The comic relief from Borderlands is Claptrap, a robot shaped like an inverted triangle on one wheel with a foul mouth and a bad attitude. He's annoying, sure, but you can't help but find the guy funny.
- In Fallout 3, one of the amenities in the player's house in Megaton or Tenpenny Tower is a robot butler. In addition to various functions useful to the player, he tells jokes when requested.
- Fallout: New Vegas has Muggy, the neurotic, mug-obsessed mini-securitron of Big Mountain. He's programmed to be obsessed, and he knows fully well that he is, and why (his whole existence is basically a pointless Take That! against Mr House, who doesn't know and wouldn't care anyway), and he can't do anything about it. He's very miserable about it.
- GLaDOS can be rather funny in both games in a rather grim way, although while the way she taunts and goads Chell may be funny to the player, it's likely not all that funny to Chell.
- In the second game, Wheatley is like this. Sure, he's trying to kill Chell, but his attempts are so dumb that he's Laughably Evil and outright hilarious. (It helps that he's voiced by British comedian Stephen Merchant.)
- In Undertale, Mettaton is a robot that people is known to crack a joke here and there. Any scene with Mettaton is bound to have a funny moment.
Mettaton(After typing a response with swear words): Oh my! This is a family-friendly TV show! Now stand still while I murder you.
- Pintsize from Questionable Content has A.I. advanced enough to have mastered making jokes about body parts he doesn't even possess and spends quite a lot of time lurking in the depths of 4Chan.
- XR from Buzz Lightyear of Star Command was created to be a serious space ranger. However, his Hive Mind creators being mentally separated during his first reconstruction resulted in him becoming a PG-rated version of Bender. He's conniving, cowardly, and constantly hitting on girls, both organic and mechanical. Nonetheless, he's still a hero when the chips are down.
- In Futurama, listing the robots without comedic traits would be easier, given the nature of the show. Still, Bender probably has the most humor potential, being part of the main cast, and his entry on the show's character sheet gives numerous reasons why.
- GIR from Invader Zim is extremely hyperactive, eats just about anything (edible or not), often spouts out random nonsense, and wears a green dog suit. His behavior isn't normal for a robot of his make since unlike the other SIR Units his brain consists of pocket lint, a paperclip, a penny, and a marble.
- Rosie the Robot from The Jetsons. A domestic-bot in a futuristic world, her humor often came from often being more rational and cool-headed than her human owners.
- The Robonic Stooges. They're The Three Stooges as androids, with all the slapstick humor that the originals did, only far more high-tech.
- Karen from Spongebob Squarepants is Plankton's snarky robotic wife, who criticizes and points out flaws in Plankton's schemes (not that it stops him from going through with them).
- The title character of Whatever Happened to... Robot Jones?. A lot of humor comes from Robot's warped perceptions of human culture and trying too hard to fit in.
- The Galaxy One prison ship in Final Space is full of Funny Robots to support its sole human prisoner, from "Insanity Avoidance Companion" KVN to the "S.A.M.E.S." (Synthetic Artificial Masses Erecting Safeness) who serve as crew to H.U.E., the onboard AI (who as of Season 2 has been downloaded into a robot body).
- Any Cybertronian comic relief characters in the various Transformers shows, such as Animated Wreck-Gar or RID '15 Fixit.
- Chopper from Star Wars Rebels enjoys pulling pranks on the rest of the Ghost crew.
