  10. Robot timeline ... 1921

  11. Robot timeline Isaac Asimov’s Laws of Robotics First Law: A robot may not injure a human being, or, through inaction, allow a human being to come to harm. Second Law: A robot must obey orders given it by human beings, except where such orders would conflict with the First Law. Third Law: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Karl Capek ... I, Robot 1921 1950
