A Golem is a creature of Jewish mythology, an animated statue (typically ceramic) brought to life by placing holy words in his mouth to serve them as workers or defenders. Famous legends include the Golem of Rabbai Loew built to defend the jewish population of Prague from antisemetic mobs. Golems are one of several myths about inanimate objects brought to life (for example the Greek God Hephaestus built gold and silver women to assist him).
Many modern fantasy works take the idea of a Golem, often using them as guards or as laborers. In many respects, golems used this sense could be thought of as supernatural robots.
