Three Laws of Robotics

In science fiction, the Three Laws of Robotics are a set of three rules written by Isaac Asimov, which most robots appearing in his fiction must obey. Introduced in his 1942 short story “Runaround”, the Laws state the following:

1. A robot may not harm a human being, or, through inaction, allow a human being to come to harm.

2. A robot must obey the orders given to it by human beings except where such orders would conflict with the First Law.

3. A robot must protect its own existence, as long as such protection does not conflict with the First or Second Law.
