ThreeLawsOfRobotics
A set of three laws set up by IsaacAsimov, which Robots, appearing in his novels, have to obey:
: 1. A robot may not harm a human being, or allow a human being to be harmed
: 2. A robot must obey the orders given by the human beings, except where such orders would conflict with the First Law.
: 3. A robot must protect his own existence, as long as such protection does not conflict the First or Second Law.
