== Plot ==
=== Synopsis === The play begins in a factory that makes artificial workers from synthetic organic matter. (As living creatures of artificial flesh and blood, that later terminology would call androids, the playwright's 'roboti' differ from later fictional and scientific concepts of inorganic constructs.) Robots may be mistaken for humans but have no original thoughts. Though most are content to work for humans, eventually a rebellion causes the extinction of the human race.
=== Prologue (Act I in the Selver translation) === thumb|A scene from the play, showing three robots Helena, the daughter of the president of a major industrial power, arrives at the island factory of Rossum's Universal Robots. Here, she meets Domin, the General Manager of R.U.R., who relates to her the history of the company. Rossum had come to the island in 1920 to study marine biology. In 1932, Rossum had invented a substance like organic matter, though with a different chemical composition. He argued with his nephew about their motivations for creating artificial life. While the elder wanted to create animals to prove or disprove the existence of God, his nephew only wanted to become rich. Young Rossum finally locked away his uncle in a lab to play with the monstrosities he had created and created thousands of robots. By the time the play takes place (circa the year 2000),<ref>According to the poster for the play's opening in 1921; see Klima, Ivan (2004) "Introduction" to ''R.U.R.'', Penguin Classics</ref> robots are cheap and available all over the world. They have become essential for industry.
After meeting the heads of R.U.R., Helena reveals that she is a representative of the League of Humanity, an organization that wishes to liberate the robots. The managers of the factory find this absurd. They see robots as appliances. Helena asks that the robots be paid, but according to R.U.R. management, the robots do not "like" anything.
Eventually Helena is convinced that the League of Humanity is a waste of money, but still argues robots have a "soul". Later, Domin confesses that he loves Helena and forces her into an engagement.
=== Act I (Act II in Selver) === Ten years have passed. Helena and her nurse Nana discuss current events, the decline in human births in particular. Helena and Domin reminisce about the day they met and summarize the last ten years of world history, which has been shaped by the new worldwide robot-based economy. Helena meets Dr. Gall's new experiment, Radius. Dr. Gall describes his experimental robotess, also named Helena. Both are more advanced, fully-featured robots. In secret, Helena burns the formula required to create robots. The revolt of the robots reaches Rossum's island as the act ends.
=== Act II (Act III in Selver) === thumb|Final scene of Act II The characters sense that the very universality of the robots presents a danger. Echoing the story of the Tower of Babel, the characters discuss whether creating national robots who were unable to communicate beyond their languages would have been a good idea. As robot forces lay siege to the factory, Helena reveals she has burned the formula necessary to make new robots. The characters lament the end of humanity and defend their actions, despite the fact that their imminent deaths are a direct result of their choices. Busman is killed while attempting to negotiate a peace with the robots. The robots storm the factory and kill all the humans except for Alquist, the company's Clerk of the Works (Head of Construction). The robots spare him because they recognize that "He works with his hands like a robot. He builds houses. He can work."<ref>{{cite book | last=Čapek | first=Karel | title=''R.U.R.'' | others=translated by Paul Selver and Nigel Playfair | publisher=Dover Publications | year=2001 | page=49}}</ref>
=== Act III (Epilogue in Selver) === Years have passed. Alquist, who still lives, attempts to recreate the formula that Helena destroyed. He is a mechanical engineer, though, with insufficient knowledge of biochemistry, so he has made little progress. The robot government has searched for surviving humans to help Alquist and found none alive. Officials from the robot government beg him to complete the formula, even if it means he will have to kill and dissect other robots for it. Alquist yields. He will kill and dissect robots, thus completing the circle of violence begun in Act Two. Alquist is disgusted. Robot Primus and Helena develop human feelings and fall in love. Playing a hunch, Alquist threatens to dissect Primus and then Helena; each begs him to take him- or herself and spare the other. Alquist now realizes that Primus and Helena are the new Adam and Eve, and gives the charge of the world to them.
== Čapek's conception of robots == [[File:Wpa-marionette-theater-presents-rur.jpg|thumb|U.S. WPA Federal Theatre Project poster for the production by the Marionette Theatre, New York, 1939]] The robots described in Čapek's play are not robots in the popularly understood sense of an automaton. They are not mechanical devices, but rather artificial biological organisms that may be mistaken for humans. A comic scene at the beginning of the play shows Helena arguing with her future husband, Harry Domin, because she cannot believe his secretary is a robotess:
<blockquote><poem> DOMIN: Sulla, let Miss Glory have a look at you. HELENA: (stands and offers her hand) Pleased to meet you. It must be very hard for you out here, cut off from the rest of the world. SULLA: I do not know the rest of the world Miss Glory. Please sit down. HELENA: (sits) Where are you from? SULLA: From here, the factory. HELENA: Oh, you were born here. SULLA: Yes I was made here. HELENA: (startled) What? DOMIN: (laughing) Sulla isn't a person, Miss Glory, she's a robot. HELENA: Oh, please forgive me... </poem></blockquote>
His robots resemble more modern conceptions of man-made life forms, such as the Replicants in ''Blade Runner'', the "hosts" in the ''Westworld'' TV series and the humanoid Cylons in the re-imagined ''Battlestar Galactica'', but in Čapek's time there was no conception of modern genetic engineering (DNA's role in heredity was not confirmed until 1952). There are descriptions of kneading-troughs for robot skin, great vats for liver and brains, and a factory for producing bones. Nerve fibers, arteries, and intestines are spun on factory bobbins, while the robots themselves are assembled like automobiles.<ref name="jr">Rieder, John "Karl Čapek" in Mark Bould (ed.) (2010) ''Fifty Key Figures in Science Fiction''. London, Routledge. {{ISBN|9780415439503}}. pp. 47–51.</ref> Čapek's robots are living biological beings, but they are still ''assembled'', as opposed to ''grown'' or ''born''.
One critic has described Čapek's robots as epitomizing "the traumatic transformation of modern society by the First World War and the Fordist assembly line".<ref name="jr" />
=== Origin of the word robot === thumb|Logo of Rossum's Universal Robots corporation, from the first edition title page (1920) The play introduced the word ''robot'', which displaced older words such as "automaton" or "android" in languages around the world. In an article in ''Lidové noviny'', Karel Čapek named his brother Josef as the true inventor of the word.<ref>{{Cite web |url=http://capek.misto.cz/english/robot.html |title=Who did actually invent the word 'robot' and what does it mean? |access-date=25 July 2013 |archive-url=https://web.archive.org/web/20130727132806/http://capek.misto.cz/english/robot.html |archive-date=27 July 2013}}</ref><ref>Margolius, Ivan (Autumn 2017) [https://czechfriends.net/images/RobotsMargoliusJul2017.pdf "The Robot of Prague"].

The name ''Rossum'' is an allusion to the Czech word ''rozum'', meaning "reason", "wisdom", "intellect" or "common sense".<ref name="ar" /> It has been suggested that the allusion might be preserved by translating "Rossum" as "Reason" but only the Majer/Porter version translates the word as "Reason".<ref name="ik" />

The amateur theater group ''Klicpera'' in Hradec Králové, which was supposed to mount a production after the premiere, was not informed about the date change in the National Theater, so their opening night on 2 January 1921 was the actual world premiere.{{refn|{{Cite web|title=Databáze amatérského divadla, soubor Klicpera|url=http://www.amaterskedivadlo.cz/main.php?data=soubor&id=14465|language=cs|access-date=2023-04-27}}}}}}
By 1921, Paul Selver translated either the original 1920 edition of ''R.U.R.'' or a manuscript copy close to this version into English.{{NoteTag|No copies of Selver's original translation are known to exist. An approximation of the original translation can be reconstructed from the Doubleday and Oxford University Press editions, as well as copies of the Theatre Guild prompt book and a version submitted to the Lord Chamberlain's Office by St Martin's Theatre, though all these versions are based on Playfair's adaptation, and most include at least some changes by the Theatre Guild.{{refn|name=Philmus 2001}}}} He probably translated the play freelance, and sold it to St Martin's Theatre in London. Selver's translation was adapted for the British stage by Nigel Playfair in 1922, but it was not produced straight away. Later that year performance rights for the U.S. and Canada were sold to the New York Theatre Guild, perhaps during Lawrence Langner's visit to Britain. Playfair's version included several changes to Čapek's original play, such as renaming the acts (the prologue became act one, and the heavily abridged final act became the epilogue), omitting around sixty lines (including most of Alquist's final speech), adding several more lines, and removing the robot character Damon (giving his lines to Radius). The omission of some lines may have been censorship from the Lord Chamberlain's Office, or self-censorship in anticipation of this, while some other changes might have been made by Čapek himself if Selver was working from a manuscript copy.{{NoteTag|The possibility that Selver was working from a partially revised manuscript by Čapek is supported by textual evidence of the Doubleday and Oxford University Press editions, and also a copy of the final lines of the play in a letter from Čapek to Edward Marsh.{{refn|name=Philmus 2001}}}} An edition of Playfair's adaptation was published by the Oxford University Press in 1923, and Selver went on to write a satiric novel ''One, Two, Three'' (1926) based on his experiences getting ''R.U.R.'' staged.<ref name="Philmus 2001"/>
The American première was produced by the Theatre Guild at the Garrick Theatre in New York City in October 1922, where it ran for 184 performances. In the first performance, Domin was portrayed by Basil Sydney, Marius by John Merton, Hallemeier by Moffat Johnston, Alquist by Louis Calvert, Busman by Henry Travers, the robot Helena by antiwar activist Mary Crane Hone in her Broadway debut, and Primus by John Roche.<ref>{{cite wikisource | first=Karel | last=Čapek | author-link=Karel Čapek | translator-first=Paul | translator-last=Selver | translator-link=Paul Selver | chapter=The cast of the Theatre Guild Production | title=R.

In June 1923, Čapek sent a letter to Edward Marsh, with the final lines of ''R.U.R.'' that had been omitted from the Selver/Playfair editions, which he described as being "suppressed in [the] English version".{{NoteTag|The final lines written by Čapek in this letter miss out sentences that are in both published Czech editions.

=== Critical reception === Reviewing the New York production of ''R.U.R.'' in 1922, ''The Forum'' magazine described the play as "thought-provoking" and "a highly original thriller".<ref>Holt, Roland (November 1922) "Plays Tender and Tough". pp. 970–976. ''The Forum''</ref> John Clute has lauded ''R.U.R.'' as "a play of exorbitant wit and almost demonic energy" and lists the play as one of the "classic titles" of inter-war science fiction.<ref>{{cite book |last=Clute |first=John |author-link=John Clute |title=Science Fiction: The Illustrated Encyclopedia |year=1995 |publisher=Dorling Kindersley |isbn=0-7513-0202-3 |pages=119, 214 }}</ref> Luciano Floridi has described the play thus: "Philosophically rich and controversial, ''R.U.R.'' was unanimously acknowledged as a masterpiece from its first appearance, and has become a classic of technologically dystopian literature."<ref>Floridi, Luciano (2002) ''Philosophy and Computing: An Introduction''. Taylor & Francis. p.207. {{ISBN|0203015312}}</ref> Jarka M. Burien called ''R.U.R.'' a "theatrically effective, prototypal sci-fi melodrama".<ref name="JMB" />
On the other hand, Isaac Asimov, author of the ''Robot'' series of books and creator of the Three Laws of Robotics, stated: "Čapek's play is, in my own opinion, a terribly bad one, but it is immortal for that one word. It contributed the word 'robot' not only to English, but through English, to all the languages in which science fiction is now written."<ref name=AsimovVocab /> In fact, Asimov's "Laws of Robotics" are specifically and explicitly designed to prevent the kind of situation depicted in ''R.U.R.'', since Asimov's robots are created with a built-in total inhibition against harming human beings or disobeying them.
Despite getting mostly positive responses, Čapek himself was very disappointed by critics' simplistic understanding of the play. He saw the play as part comedy, and ending with faith that humanity would survive albeit in a different form, while the critics often considered it to be pessimistic or nihilistic, and purely either an updated ''Frankenstein'', an anti-capitalist satire, or a critique of contemporary political ideologies. The critics' interpretation may have been influenced by how heavily abridged the final act (or Epilogue) was in the Selver/Playfair translation.<ref name="Fox 1981"/>
== Adaptations == * On 11 February 1938, a 35-minute adaptation of a section of the play was broadcast on BBC Television — the first piece of television science-fiction ever to be broadcast.
