This clip is a generic, user-uploaded sci-fi sound effect rather than a line or cue taken from a specific film, game or show, and no single original source is documented for it. Sounds like this circulate on soundboards where creators search for short, ready-to-use robot and futuristic effects for edits, memes and gaming videos. Its appeal comes from its brevity and instantly recognisable machine-roar texture, which fits robot reveals, cyborg characters and high-tech transitions without needing dialogue or music. That versatility keeps it useful for quick, punchy edits.
