Laws of Robotics Isaac Asimov gave laws of robotics in his sto- ry “Runaround” in 1942. The first law states that a robot must not injure a human being. The sec- ond law says that a robot must obey all orders giv- en by human beings. The third law says that a robot must protect its existence. However, these laws can be disobeyed if they clash with some higher law.
