The famous author of science fiction Isaac Asimov (1920-1992) conceived three important principles pertaining to robots in the 1940s, known as "Asimov's Three Laws of Robotics." Ths first law is "a robot must never harm human beings or, through inaction, allow a human being to be harmed." The second law is "a robot must obey the orders from human beings except where such orders conflict with the first law," and the third law is "a robot must protect its own existence as long as such protection does not conflict with the first and second laws."
