robin (n.): common European songbird, 1540s, shortening of Robin Redbreast (mid-15c.), from masc. personal name Robin, also (in reference to the bird) in the diminutive form robinet. Redbreast alone for the bird is from early 15c., and the Robin might have been added for the alliteration. It ousted the native ruddock. In North America, the name was applied to the red-breasted thrush by 1703. Robin's egg as a shade of blue is attested from 1881.

robot (n.): 1923, from English translation of 1920 play "R.U.R." ("Rossum's Universal Robots"), by Karel Capek (1890-1938), from Czech robotnik "slave," 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).
