robotics (n.)

1923, "mechanical person," also "person whose work or activities are entirely mechanical," from the English translation of the 1920 play "R.U.R." ("Rossum's Universal Robots") by Karel Capek (1890-1938), from Czech robotnik "forced worker," from robota "forced labor, compulsory service, drudgery," from robotiti "to work, drudge," from an Old Czech source akin to Old Church Slavonic rabota "servitude," from rabu "slave" (from Old Slavic *orbu-, from PIE *orbh- "pass from one status to another;" see orphan).

The Slavic word thus is a cousin to German Arbeit "work" (Old High German arabeit). The play was enthusiastically received in New York from its Theatre Guild performance debut on Oct. 9, 1922. According to Rawson the word was popularized by Karel Capek's play, "but was coined by his brother Josef (the two often collaborated), who used it initially in a short story." Hence, "a human-like machine designed to carry out tasks like a human agent."

"Young Rossum invented a worker with the minimum amount of requirements. He had to simplify him. He rejected everything that did not contribute directly to the progress of work—everything that makes man more expensive. In fact, he rejected man and made the Robot. My dear Miss Glory, the Robots are not people. Mechanically they are more perfect than we are, they have an enormously developed intelligence, but they have no soul."  ["R.U.R."]

in the names of sciences or disciplines (acoustics, aerobics, economics, etc.), a 16c. revival of the classical custom of using the neuter plural of adjectives with Greek -ikos "pertaining to" (see -ic) to mean "matters relevant to" and also as the titles of treatises about them. Subject matters that acquired their English names before c. 1500, however, tend to be singular in form (arithmetic, logic, magic, music, rhetoric). The grammatical number of words in -ics (mathematics is/mathematics are) is a confused question.
