From the same root as "cerveau", the French for brain?

[edit]A quick Google suggests to me it derives from a Latin root, meaning one who serves/maintains, I guess meaning one who maintains (a position) in place of the controlling function.[/edit]

Well, a servomechanism maintains some controlled parameter, like angular position in the case of an R/C servo, once commanded.
"Servo" is just a diminutive of "servomechanism".

From Latin, servus = slave, so a servo motor is a slaved motor, ie controlled operation as opposed to free running.

Servo is the latin for "I serve", simple as that.  Just like video means "I see".  Its just accident of history that in mechanics we say controller & servo and in software we say master & slave.

@MarkT
And a California lawsuit shows that it's not a bad idea to use Latin instead of English smiley-wink
