The word "robot" first appeared in Karel Čapek's play R.U.R. (1920; trans 1923), and is derived from the Czech robota (statute labour). Čapek's robots were artificial human beings of organic origin, but the term is usually applied to Machines. Real-life assembly-line robots are adapted to specific functions, but in sf – where the term overlaps to some extent with Androids – it usually refers to machines in more-or-less human form.
Machines which mimic human form date back, in both fiction and reality, to the early nineteenth century. The real automata were showpieces: clockwork dummies or puppets. Their counterparts in the fiction of E T A Hoffmann – the Talking Turk in "Automata" (1814) and Olympia in "Der Sandmann" ["The Sandman"] (comprising volume one of Nachtstücke, 1816) – present a more verisimilitudinous image, and play a sinister role, their wondrous artifice being seen as something blasphemous and diabolically inspired. The automaton in Herman Melville's "The Bell-Tower" (August 1855 Putnam's Monthly) has similar allegorical connotations. Early-twentieth-century works are markedly different. William Wallace Cook's A Round Trip to the Year 2000 (July-November 1903 Argosy; 1903), which features robotic "mugwumps", and the anonymous skit Mechanical Jane (1903) are both comedies, as is J Storer Clouston's Button Brains (1933), a novel in which a robot is continually mistaken for its human model and which introduced most of the mechanical-malfunction jokes that remain the staple diet of stage and television plays featuring robots. (Robots are the most common sf device used in drama because they can be so conveniently and so amusingly played by live actors; the tradition extends to recent times in Alan Ayckbourn's Henceforward  and in Red Dwarf, while one of the better comic sequences in Sleeper  has the human protagonist ineptly impersonating a robot.)
Early Pulp-magazine stories about robots are generally ambivalent. David H Keller's "The Psychophonic Nurse" (November 1928 Amazing) is a cooperative servant, but no substitute for a mother's love. Abner J Gelula's "Automaton" (November 1931 Amazing) has lecherous designs on its creator's daughter and has to be destroyed. Harl Vincent's "Rex" (June 1934 Astounding) takes over the world and is about to remake Man in the image of the robot when his regime is overthrown. But the balance soon swung in favour of sympathy. The machines in Eando Binder's "The Robot Aliens" (February 1935 Wonder Stories) come in peace but are misunderstood and abused by hostile humans. Saccharine sentimentality is also in the ascendant in "Helen O'Loy" (December 1938 Astounding) by Lester del Rey, in which a man marries the ideal mechanical woman; in "Robots Return" (September 1938 Astounding) by Robert Moore Williams, in which spacefaring robots discover that they were created by humans and accept the disappointment nobly; in "Rust" (October 1939 Astounding) by Joseph E Kelleam, which describes the tragic decline into extinction of mechanical life on Earth; in the anti-Frankensteinian parable "'I, Robot'" (January 1939 Amazing) by Eando Binder – this launched the influential Adam Link sequence, many collected as Adam Link – Robot (January 1939-April 1942 Amazing; fixup 1965); and in "True Confession" (February 1940 Thrilling Wonder) by F Orlin Tremaine and "Almost Human" (March 1941 Super Science Stories) by Ray Cummings, both of which feature altruistic acts of robotic self-sacrifice. Isaac Asimov claims to have invented (with John W Campbell Jr's help) his famous Laws of Robotics in response to a technophobic "Frankenstein Complex" – a term he introduced in "Little Lost Robot" (March 1947 Astounding) – but there is little evidence of one in the robot stories published around the time of "Strange Playfellow" (September 1940 Super Science Stories; vt "Robbie" in I, Robot, coll 1950). Robots are given higher status than mere humans in "Farewell to the Master" (October 1940 Astounding) by Harry Bates and "Jay Score" (May 1941 Astounding) by Eric Frank Russell, the first of a series later published as Men, Martians and Machines Men, Martians and Machines (May 1941-October 1943 Astounding; exp as coll of linked stories 1955).
The system of ethics with which Asimov's Positronic Robots were hardwired was enshrined in the three famous Laws of Robotics (devised in discussions with John W Campbell Jr, whom Asimov insisted was their co-creator). The laws emerged from "Reason" (April 1941 Astounding); "Liar!" (May 1941 Astounding) became the first of many Asimov stories whose plots involve the explication of odd robot behaviour as an unexpected consequence of them. In "Liar!" (as in many others) the logical unravelling is accomplished by the "robopsychologist" Susan Calvin. The early stories in the series – collected in I, Robot (coll of linked stories 1950) – culminated in "Evidence" (September 1946 Astounding), in which a robot politician can get elected only by convincing voters that he is human, but does the job far better than the man he replaces. In C L Moore's "No Woman Born" (December 1944 Astounding) a dancer whose mind is resurrected in a robot body quickly concludes that the robot condition is preferable to the human. The robot servants who survive mankind in Clifford D Simak's City (May 1944-December 1947 Astounding, January 1951 Fantastic Adventures; fixup 1952; exp 1981) are the perfect gentlemen's gentlemen rather than mere slaves. One cautionary note was sounded by Anthony Boucher, whose stories "Q.U.R." (March 1943 Astounding) and "Robinc" (September 1943 Astounding), both as by H H Holmes, champion "usuform robots" against anthropomorphous ones; the stated reasons are utilitarian, but Boucher's religious faith – he was a devout Catholic – may have influenced his opinion. The most notable comic robot in pulp sf – outside the works of the prolific Ron Goulart, which are infested by logically malfunctioning robots of every conceivable variety, not exclusively with comic intent – is the narcissistic machine in Robots Have No Tails (stories January 1943-April 1948 Astounding; coll of linked stories 1952) by Henry Kuttner (as Lewis Padgett).
After 1945, when the atom bomb provoked a new suspicion of technology, attitudes to robots in sf became more ambivalent again. In 1947 Asimov published his first sinister-robot story, "Little Lost Robot" (March 1947 Astounding Science-Fiction), and Jack Williamson produced the classic "With Folded Hands . . ." (July 1947 Astounding), in which robot "humanoids" charged with the Prime Directive "to serve man, to obey, and to guard men from harm" take their mission too literally, and set out to ensure that no one endangers their own well being and that everyone is happy, even if that requires permanent tranquillization or prefrontal lobotomy. Many writers did not relinquish their loyalty to machines; Asimov and Simak remained steadfastly pro-robot, and Williamson relented somewhat in his sequel to "With Folded Hands . . .", The Humanoids (March-May 1948 Astounding as ". . . And Searching Mind"; rev 1949) – although the ending of the novel may have been suggested by John W Campbell Jr rather than being a spontaneous expression of Williamson's own technophilic tendencies – but most robot stories of the 1950s involve some kind of confrontation and conflict. Robots kill or attempt to kill humans in "Lost Memory" (May 1952 Galaxy) by Peter Phillips, "Second Variety" (May 1953 Space Science Fiction) by Philip K Dick, "Short in the Chest" (July 1954 Fantastic Universe) by Idris Seabright (Margaret St Clair), "First to Serve" (May 1954 Astounding) by Algis Budrys, The Naked Sun (1956) by Asimov and "Mark XI" (May 1957 Saturn; vt "Mark Elf" in You Will Never Be the Same, coll 1963) by Cordwainer Smith. A UFO-borne robot Invasion of Earth is central to Lionel Fanthorpe's comically inept March of the Robots (1961) as by Leo Brett. In Comics, Dan Dare – Pilot of the Future has to deal with conquering hordes of "Elektrobots" and subsequently "Selektrobots" commanded by his nemesis the Mekon.
The mistaken-identity motif takes on sinister or unfortunate associations in Asimov's "Satisfaction Guaranteed" (April 1951 Amazing), Dick's "Impostor" (June 1953 Astounding), Walter M Miller's "The Darfsteller" (January 1955 Astounding) and Robert Bloch's "Comfort Me, My Robot" (January 1955 Imagination). Robot courtroom dramas include Simak's "How-2" (November 1954 Galaxy), Asimov's "Galley Slave" (December 1957 Galaxy) and del Rey's "Robots Should Be Seen" (January 1958 Venture). Man-robot boxing matches are featured in "Title Fight" (December 1956 Fantastic Universe) by William Campbell Gault, "Steel" (May 1956 F&SF) by Richard Matheson and "The Champ" (1958 Science Fantasy #29) by Robert Presslie. The robot is an instrument of judgement in "Two-Handed Engine" (August 1955 F&SF) by Kuttner and C L Moore. Black comedies involving robots include several stories by Robert Sheckley, notably "Watchbird" (February 1953 Galaxy), "The Battle" (September 1954 If) and "A Ticket to Tranai" (October 1955 Galaxy), although Sheckley's classic story in this vein – extracting grim hilarity from a robot's inflexible literal-mindedness – was the later "The Cruel Equations" (1971 BOAC). One story which deviates markedly from the pattern is Boucher's Catholic fantasy "The Quest for St Aquin" (in New Tales of Space and Time, anth 1951, ed Raymond J Healy), in which a perfectly logical robot emulates Thomas Aquinas and deduces the reality of God; but in the main robot stories of the 1950s reflected profound anxieties concerning the relationship between Man and machine. Asimov's The Caves of Steel (1954), which deals in some depth with its hero's anti-machine prejudices and his mechanized environment, brings this anxiety clearly into focus.
As post-Hiroshima anxiety began to ebb away in the late 1950s, a more relaxed attitude to the robot became evident, humour and gentle irony coming to the fore in such stories as those in Harry Harrison's War with the Robots (1958-1962 var mags; coll 1962), Brian W Aldiss's "But Who Can Replace a Man?" (June 1958 Infinity Science Fiction; vt "Who Can Replace a Man?" in The Canopy of Time, coll 1959), Fritz Leiber's The Silver Eggheads (January 1959 F&SF; exp 1962) and Poul Anderson's "The Critique of Impure Reason" (November 1962 If). The old sentimentality returned to the robot story in full force in Simak's "All the Traps of Earth" (March 1960 F&SF), and soon reached new depths of sickliness in Ray Bradbury's "I Sing the Body Electric!" (August 1969 McCall's). The rehabilitation of the robot was completed by Barrington J Bayley's study in robot existentialism, The Soul of the Robot (1974; rev 1976), and its sequel, The Rod of Light (1985), and by Asimov's "– That Thou Art Mindful of Him!" (May 1974 F&SF) and "The Bicentennial Man" (in Stellar #2, coll 1976, ed Judy-Lynn del Rey), which took the robot's philosophical self-analysis to its logical conclusion, ending with the identification of the robot as a thoroughly "human" being. Asimov later set out to integrate his robot stories into the Future History of his Foundation series in such novels as The Robots of Dawn (1983) and Robots and Empire (1985); he also wrote a series of juvenile robot stories in collaboration with his wife Janet Asimov, begun with Norby the Mixed-Up Robot (1983), and lent his name to a series of Shared-World novels set in Isaac Asimov's Robot City, begun with Odyssey (1987) by Michael P Kube-McDowell. Janet Asimov carried the family tradition forward in Mind Transfer (1988), which explores the possibilities of robot Sex alongside philosophical discussions of robotic "humanness". Other exercises in robot existentialism are featured in Sheila MacLeod's Xanthe and the Robots (1977) and Walter Tevis's angst-ridden Mockingbird (1980).
Robot philosophy of a less earnest but cleverer kind is extensively featured in Stanisław Lem's robotic fables, collected in The Cyberiad (coll 1965; trans 1974) and Mortal Engines (coll trans 1977). Robot Religion and Mythology are featured in Robert F Young's "Robot Son" (September 1959 Fantastic Universe), Roger Zelazny's "For a Breath I Tarry" (March 1966 New Worlds), Simak's A Choice of Gods (1972) and Gordon Eklund's "The Shrine of Sebastian" (in Chains of the Sea, anth 1973, ed Robert Silverberg). The integration of the robot into human religious culture is celebrated in Robert Silverberg's "Good News from the Vatican" (in Universe 1, anth 1971, ed Terry Carr), about the election of the first robot pope. Some humans, at least, are prepared to fight for the freedom of ex-colonial robots in James P Hogan's Code of the Lifemaker (1983). The awkward question of whether one would let one's daughter marry a robot is squarely addressed in Tanith Lee's The Silver Metal Lover (1982), and the problems of an orphaned robot trying to get by in a puzzling and hostile world are hilariously (though ultimately tragically) displayed in Roderick (1980) and Roderick at Random (1983) by John T Sladek. The homicidal robot, although an endangered species, has not quite become extinct: a plausible belief that the titular robot is both vengeful and murderous drives the plot of Roger Zelazny's Home is the Hangman (November 1975 Analog; 1990 chap dos), and a robot psychopath whose "asimov circuits" have failed is the Antihero of Sladek's Tik-Tok (1983).
The killer-robot, however, made its most successful comeback during the 1980s and 1990s in movies rather than books, an influential example being The Terminator (1984) and its numerous sequels and spinoffs (> Cinema for further instances). The gloom-ridden "paranoid android" Marvin (actually a robot), with his "brain the size of a planet", is a major character in the various versions of Douglas Adams's Hitch Hiker's Guide to the Galaxy saga, and for a time attained cult-hero status. Other well-loved tv robots include the older example in Lost in Space whose catchphrase was "Danger, Will Robinson! Danger!", the comically androidal Kryten in Red Dwarf and the thoroughly Antiheroic Bender in Futurama. But the paranoid vision of robots warring against humanity never quite dies out, as witness Daniel H Wilson's jocular doomsaying in How to Survive a Robot Uprising (2005) and more serious treatment of the old theme in his Robopocalypse sequence comprising Robopocalypse (2011) and Robogenesis (2014).
The writer whose work confirms the identification of Man and robot most strongly is Philip K Dick, who usually preferred the term "android". His most notable stories using humanoid machines to address the question of what the word "human" can or should mean are Do Androids Dream of Electric Sheep? (1968), "The Electric Ant" (October 1969 F&SF) and We Can Build You (November 1969-January 1970 Amazing as "A Lincoln, Simulacrum"; text restored 1972). "Someday," he said in his essay "The Android and the Human" (December 1972 SF Commentary), "a human being may shoot a robot which has come out of a General Electrics factory, and to his surprise see it weep and bleed. And the dying robot may shoot back and, to its surprise, see a wisp of gray smoke arise from the electric pump that it supposed was the human's beating heart. It would be rather a great moment of truth for both of them." This irony is explored through the character Jonas in Gene Wolfe's The Book of the New Sun (1980-1983 4vols), a robot who has acquired human prostheses.
For the giant battle robots of Japanese anime and related sf, which are typically though not invariably operated by human pilots, see Mecha. The mecha franchise most famous in the West is Transformers, discussed in the entry for The Transformers – The Movie (1986).
Anthologies of robot stories are very numerous and include The Robot and the Man (anth 1953) edited by Martin Greenberg, The Coming of the Robots (anth 1963) edited by Sam Moskowitz, Invasion of the Robots (anth 1965) edited by Roger Elwood, and The Metal Smile (anth 1968) edited by Damon Knight. Science Fiction Thinking Machines (anth 1954) edited by Groff Conklin has a section on robots. [BS/DRL]
