A device, system, or organism that can restore, repair, or rebuild itself without external assistance or intervention.
From 'auto-' (self), 'regenerate' (to grow back or restore), and '-or' (one who does). This term emerged as engineers developed systems that could self-repair and as biologists studied organisms with regenerative abilities.
Starfish are nature's perfect autoregenerators—they can literally grow back a lost arm, but scientists are now building robotic systems that can repair themselves too, which is basically 21st-century sorcery.
