- Karel Capek's play, R.U.R. (which coined the very term "robot") probably created this trope. Ironically, the "robots" in the play are not truly robots in the way modern culture views them. Modern science would likely call them biological robots or Artificial Humans. That being said, the robots are mass-produced with every piece built and put together like a car on a factory line. At one point the characters are discussing how human the robots are:HELENA: Doctor, has Radius a soul?
DR. GALL: I don't know. He's got something nasty.
- In The Hitchhiker's Guide to the Galaxy, there is the Sirius Cybernetics Corporation's "Genuine People Personalities" feature.
- The elevator which refuses to take Zaphod Beeblebrox in the direction he wants to go because it's afraid really is an example of this trope. There is no reason why anyone would need an intelligent elevator, and all it does is make the whole thing a lot less efficient.
- The Heart of Gold's doors are a good (or bad, depending on perspective) example of this. Of note is that this is most frequently criticized by Marvin, himself a perfect example of this trope; he doesn't like the one they gave him, so there's no unintentional irony/hypocrisy on his part.
- Marvin is mostly dissatisfied with the GPP feature due to the fact that in his role and the way he is put to use on the Heart of Gold he is extremely subchallenged which causes him severe depression. The real problem is that his IQ is way too high for him to ever be challenged, so they really should just make stupider robots.
- The short story "Young Zaphod Plays It Safe" argues that Ridiculously Human Robots would be incredibly dangerous. The Sirius corporation's "Designer People" product were robots that were sort of super-sociopaths—some of them were built to look like people, and unlike most Genuine People Personalities they could act totally convincing if they wanted, but they lack certain normal thought processes of natural organisms like consciences or even sanity. One of them is described as being as dangerous as planet-killing weapons of mass destruction. In some editions of the story, its name is revealed as Reagan.
- Doubly parodied and lampshaded in Dirk Gently's Holistic Detective Agency, where an Electric Monk from an alien planet finds itself on Earth. Physically, it resembles a human being so closely that no one catches on that it's a robot ... even though, on its planet of origin, it was given such ridiculous features as two legs, two arms, and a single nose so it couldn't possibly be mistaken for a person. Mentally, it had been designed with a human-like ability to believe things — even quite ridiculous or self-contradictory things — which is something nobody's figured out how we do, let alone how to make a machine do it. The Electric Monk was given this ability so that it could listen to door-to-door evangelists in its owners' stead.
- Isaac Asimov:
- R. Daneel Olivaw, from the Robot series. In The Robots of Dawn, we learn that Dr. Fastolfe and Dr. Sarton had a really hard time overcoming the Uncanny Valley when designing him, and it took something like a century, but eventually they managed to pull off a robot that actually feels like an actual human. Daneel can even eat: he does so by putting the food in a bag that can be later thrown away.
- And in The Robots of Dawn, we meet the other humaniform robot ever constructed, R. Jander Panell, whose "murder" is the subject of the book's mystery. We also learn that Jander (and, presumably by extension, Daneel) is, like Data, "fully functioning".
- And in Prelude to Foundation, set about twenty thousand years after The Robots of Dawn, we meet R. Dors Venabili, yet "another" humaniform robot (this time female) designed by Daneel to become Hari Seldon's protector and companion. Not only is Dors fully functional, but she eventually develops genuine love for Seldon and actually violates the First Law to protect him.
- There's also Stephen Byerley, in the short story 'Evidence.' His political opponent started a rumor that Byerley was a robot... and though Byerley denied it, he also declined to be X-rayed to prove his humanity. He eventually convinced people that he was human by punching out a heckler, an act clearly impossible for a robot under the First Law if not for the fact that the heckler was another apparently-human robot constructed for the occasion.
- And the 'Bicentennial Man,' who made himself a Ridiculously Human Robot. Over the course of two centuries, he started to make artwork, wear clothes, modify himself to be more human ... even to the point of choosing to become mortal and die (this would seem to probably break the Third Law of Robotics, too, but the eponymous Andrew has a short speech specifically to counter that).
- 'Let's Get Together': eleven humaniform robots are constructed, each a copy of a scientist.
- 'The Tercentenary Incident': the human President of the United States was disintegrated, and replaced with his robotic double, who was originally meant to just be a body double for him at formal events. It's implied that the robot did a much better job of being President than the human ever could have.
- And there's the equal-rights metallos from an earlier story.
- And please note that all of the above robots from Asimov's works had a solid, justified reason for being so human (namely, they had to pass as human in order to fulfill their function), except, arguably, for Jander Panell (both he and Daneel were made for research purposes).
- Tony from "Satisfaction Guaranteed". Ultimately, the trope is averted—Tony was so humanlike that the test subject became infatuated with him, and Dr. Calvin recommends that future TN models be made less anthropomorphic for this exact reason.
- In Forward the Foundation, Hari and Dors have to teach Daneel how to laugh. The goal is to discredit a political activist, whom Hari's adopted son told that First Minister Eto Demerzel (The Emperor's chief advisor and one of Daneel's disguises) is a robot. The activist then makes a public announcement to that effect. Hari and Dors teach Daneel to laugh so that he can publicly laugh off such accusations as ridiculous, thereby discrediting the activist. Strangely, Dors was built by Daneel, yet she can smile and laugh, and he can't.
- Despite the above examples, Asimov often averted this trope quite harshly, and went to great lengths to justify it. Even those robots that were roughly humanoid were explained to be such because they needed to be able to perform tasks which human tools for already existed and it wouldn't make sense to replace every piece of equipment when one robot could be made to use them. There is a notable exception with a certain robot designed to look roughly humanoid, even though a simple positronic computer could have been used, strictly to try and get it on Earth and weaken the whole Frankenstein Complex.
- Even the intelligence that Asimov's robots have, which leads to the unexpected deductions they begin to make, ultimately stems from the incredible complexity of the positronic brain, and the need for them to be designed in such a way as to understand human instructions as optimally as possible and know when to ignore these instructions in favor of the greater good.
- This trope is averted in Robert L. Forward's Flight of the Dragonfly. The computers are programmed to seem human, but are clearly not. In one case, a computer refuses to waste the crew's air, even though they will die if it doesn't, but a simple order to override is all that is needed to make it follow through. Later, when a computer is destroyed and one crew member is emotional about it, another computer breaks the emotional attachment with a carefully designed reminder that "After all, we are just computers."
- In Susan Swan's short short "The Man Doll", a cybernetic engineer builds an android lover as a gift for a friend, however the android's programmed need to serve the interests of those he emotionally bonds with ultimately leads him to abandon his owners and pioneer a political movement calling for the emancipation of other androids like himself whose basic functions require the existence of emotional capacities.
- Robert A. Heinlein:
- In Time Enough for Love and the later stories in the loose "series" that follows, computers either are emotionless machines, or they learn to be human from close interactions with humans. In the second case, they learn to be self-aware emotional beings from watching us, and as a result act pretty much like we do.
- In The Moon Is a Harsh Mistress, a computer gains sentience and learns to be human over the course of the book. At the start, it's, at best, a petulant child.
- In the classic "Helen O'Loy", by Lester del Rey, this trope was justified. The titular character was created to win a bet between an endocrinologist and a roboticist as to whether a robot could be made to act like a real woman. The endocrinologist insisted no robot could duplicate the complex biological system that created emotions, the roboticist insisted it could. The roboticist won, when the endocrinologist not only had to admit that she had human-like emotions, but eventually married her.
- Fred Saberhagen's Berserker series averts this trope. Because the eponymous robots are out to kill everyone, nobody wants a human-like robot around. Furthermore, the robots that people do build will remind the people around them that they have no emotions, if necessary. Most importantly, it's the berserkers' utter lack of humanity that makes them so scary.
- Justified in Charles Stross' Saturn's Children. The (extinct) "Creators" never figured out how to program self-aware AIs from scratch. Instead they just copied the way human brains work. And then you find out how they did it...
- Also justified in Mind Scan, by Robert J. Sawyer, in which the androids have uploaded human consciousness (mind scans of the title) so their personalities are those of the original human. The book revolves over whether they're "really" human, persons with legal rights, and have "souls" or not.
- Legends of Dune trilogy:
- Erasmus wasn't designed to be intelligent (although does look at least vaguely like a human—two arms, two legs, etc.) but ends up being far more so than any other robot, and this feat can't be replicated.
- Seurat, Vorian Atreides's co-pilot, also exhibits vaguely human-like behavior and eventually learns treachery. These are the only independent robots in the books, although the reprogrammed combat mek Chirox also eventually learned to display several human qualities such as regret, pride, and self-sacrifice. Omnius himself feels anger and ambition.
- Justified in Joel Shepherd's Cassandra Kresnov series. The title character is an improved version of previous androids who made good foot soldiers but not great leaders. She was given enhanced intelligence, emotions, and lateral thinking ability in order to outsmart the other side in an interplanetary war. She was even given enhanced attractiveness and an increased libido to help her relate to humans better and form interpersonal relationships. However, although she made an excellent soldier and commander, she was intelligent and independent enough to rebel against her creators and escape in order to have a life as an ordinary human.
- Keith Laumer's Bolo combat units don't look even remotely human — they're tanks the size of large buildings — but their personalities:"What made you risk everything on a hopeless attack? Why did you do it?"
"For the honor of the regiment."
A Mark XXXI Combat Unit is the finest fighting machine the ancient wars of the Galaxy have ever known. I am not easily neutralized. But I wish that my Commander's voice were with me...
- The lead protagonist of David Weber's Safehold series is a Personlity-Integrated Cybernetic Avatar, a robot with the personality of a woman named Nimue Alban downloaded into it. Nimue is fully aware of this from the get-go, and in fact wrestles on and off throughout the books with just where the line between "human" and "robot" lies with her.
- Robert A. Heinlein examines this trope in Friday. A conversation about genetically engineered Artificial Humans and "Living Artifacts" (artificial non-human lifeforms) being used as airline pilots brings up the point that a non-human artificial pilot, organic or AI, might go suicidally or homicidally insane because of its lack of ties to a human world it can never belong to. Artificial Humans like the titular Friday have to face Fantastic Racism and alienation issues, but are able to pass as human. With luck, they can even possibly find acceptance in human society without hiding what they are.
- In the Culture of Iain M. Banks, the Minds certainly qualify. All civilizations are obliged to build tendencies into AIs, because "perfect [unconstrained] AIs always Sublime," so presumably the Culture makes AIs which are naturally going to like its members and want to help them. Still, they are unfathomably mighty intellects, so there's always the suspicion in the Culture that the ridiculously human-like part of them is just the tip of the iceberg.
- Skinned does this, although with a thoroughly justifiable reason. The robots are created for the sole purpose of replacing the deceased, and so are made not only to seem like humans but to be as absolutely identical to them as possible.
- Justified in Rick Griffin's Argo, as the "humans" aren't supposed to know that they're not organic.
- The automatons from The Infernal Devices—despite walking with a graceless gait, they can pass for normal humans well enough.
- In the novel Valentina: Soul in Sapphire, by Joseph H. Delaney and Marc Stiegler, a computer virus designed with adaptive AI becomes sentient and self-aware.
- Thanks to computer nerds finally understanding the concept of exchanging bananas for bananas, MARZENA can now introduce you the concept of the Glial-Net, an internet where domains are Self-Aware AIs capable of human intelligence. Life as a Glial Robot is described as being very similar to a human but with slightly graphically crappier vision and trapped in a neverending lucid dream (or nightmare). Contrast this with Soulless Neuro Robots like Sirana who can only copy behaviors, but can't replicate the human thought process or feel emotions. Neurobots can't simultaneously coordinate enough data to become conscious, a bird flapping a single wing will never fly.
- The X-Wing Series introduces perhaps the most independent of droids, a 3PO unit called Squeaky. Squeaky managed to subvert its programming and steal a ship to lead an escape from the prison/spice mine planet Kessel. For his actions he was freed from any present and future ownership. By the time of the X-Wing series he has a highly developed personality that contrasts sharply with the standard demeanor of most 3PO units who are programmed to be courteous and polite to everyone. Squeaky routinely insults those around him and despite being originally a translator, has worked as a bartender and later as a quartermaster for the New Republic.
- We Are Legion (We Are Bob): All replicants are copied from human minds, but the Bobs are the first ones to create a VR simulation for themselves, complete with a body. Living humans clearly find this easier to deal with.
- Dragon of Worm, despite not having a physical body until late in the story, is advanced enough to have a trigger event and gain superpowers, something only humans should be able to do. She loves, hates, and has all the emotions of a real person... all while being, essentially, a not-evil Skynet.
- In C.T. Phipps' series Agent G, this turns out to be basis for the Letters. Agent G and the other assassins were created by the government and cybernetically upgraded but look as well as act identical to humans. Indeed, they're unaware they're not human until the revelation at the end of the first book.
- Zig-zagged in The Murderbot Diaries. High-intelligence AIs are shaped by their personal experiences, which tend to involve being immersed in very specific fields of work and neural links to various data feeds, but can respond quite organically to those experiences. Murderbot themself is hilariously socially awkward, obsessed with trashy media serials, and prone to extremely deadpan snark in their internal monologue. As for others...
