A cybernetic zombie, is a zombie brought back to life by cybernetic means. Such means would include galvanization, nano-robotics, or robotic articulation grafted onto a corpse. What differentiates this type of semi-mechanical zombie from a cyborg is that it is a re-animated corpse that usually has no free will, ability to reason, think for itself, or make decisions (hence the "zombie" moniker). It is either controlled by an outside source or follows programming installed within a microprocessor that allows the corpse to move.
