A word derived from "decoy" and "robot", normally used to refer to remotely controlled prosthetic bodies, etc. Coined during wartime, its not the perfect word in this case ("Musashi! Seal the m1 decot, and do a 1mw periphery clean-up pulse!"), but it's commonly used in Motoko's world. This definition is more or less taken directly from Ghost in the Shell Vol. 2 Man Machine Interface's introduction.
