Killer robot

Killer robots are a type of science fiction stock character - an artificially intelligent robot with homicidal tendencies, either deliberately programmed into them for the purposes of combat, or accidentally caused by an internal glitch or outside interference. They appear commonly in stories about robots, starting with R.U.R., a 1920 play that introduced the word "robot" into the English lexicon, in which artificial workers decide to rebel and subsequently cause the extinction of humanity. Some organizations, such as Human Rights Watch, have characterized real-life lethal autonomous weapons as "killer robots", while seeking to ban them. The depiction of killer robots reflects existential worry about the potential for harm robots possess.
