On 2058 A.D, the Book of Robotics was published as 56th edition. It was written about three laws of robotics. For the first rule, a robot must not injure a human being or allow human being to come to harm. Second, a robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law. Third, a robot has to protect itself as long as such protection does not conflict with the first or second laws.
