Asimov's Three Laws of Robotics

Overview
Author Isaac Asimov described the Three Laws of Robotics in a short story he wrote in 1942 titled "Runaround." They are:


 * First Law &mdash; A robot may not injure a human being or, through inaction, allow a human being to come to harm.
 * Second Law &mdash; A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
 * Third Law &mdash; A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
