Robots with acronyms for names

Robots whose names were acronyms, abbreviations formed from the initial components of the words in a phrase, such as S.M.I.D.S.Y., which stood for Sorry Mate, I Didn't See You.

Note: This includes robots with names which were changed to acronyms, such as Cataclysmic Variabot, which was later shortened to C.V., but does not include robots with names that were only partially acronyms, such as King B3, or Reaper NP2.
