What are the three laws of robotics?

The three laws of robotics state that a robot cannot harm a human, must obey orders and must act to protect itself in situations that will not conflict with the first two laws. These laws were created by science-fiction author Isaac Asimov.

The Three Laws of Robotics were a unifying theme through much of Asimov's work. The laws have been changed and expanded upon over the years by Asimov and other writers. Asimov's Three Laws have been featured in a number of celebrated science fictions stories, prominent films and other forms of media since they were first introduced in 1942.
