n. a machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer.

From Czech robot, taken directly into German as Robot before it moved on into English. The term had been coined by Karel Čapek for his 1920 play R.U.R., where it denoted factory-made artificial labourers; Čapek credited his brother Josef, a painter and writer, with supplying the word itself.
The underlying root is Common Slavic robota, “forced labour, corvée”, a concept whose historical echoes the mechanical figures were meant to amplify. The modern sense arrived with the play; the spelling, via German, arrived a year later.
The word arrived in English from Prague in 1920, carried by Karel Čapek’s play R.U.R. Čapek had asked his brother Josef for a convincing label for factory-produced artificial workers who would later revolt and murder their makers; Josef suggested robot, lifted from Czech robota, “forced labour”, itself from Old Czech robota signifying corvée owed to a feudal lord.
That Old Czech form descends from Proto-Slavic orbota, built on orbъ “slave, servant”, which continues a Proto-Balto-Slavic root árbas. The lineage reaches back to Proto-Indo-European h₃órbhos, the same source that gives German Arbeit and, in another branch, English orphan; the Slavic line kept the -t- suffix after the stem while Greek took a different route.
Within a decade of the play the term had crossed into English intact, and the metal labourers of Čapek’s theatre acquired a generic name. Polish robotnik and Russian работник, both simply meaning “worker”, share the root but were never the conduit; the borrowing happened directly from Czech stage directions to international vocabulary, with no intermediate stop.
2008, Randall Munroe releases the ROBOT9000 script to silence repeated chatter. A 4chan board adopts the filter, takes the abbreviation /r9k/, and starts to fill with anonymised confessions of social fatigue. The script’s name shortens naturally to r9k, the numeral echoing the original tag.
Whether the second, human sense — “robot” as someone affectless, moving through normal exchanges with the blank competence of circuitry — drifted in later or was already understood among the board’s first users is a question that bored moderators have left open.
