Assimov's three Laws of robotics - 1942
These were first set out in Isaac Asimov's short story Runaround, published in Astounding.
- A robot may not injure a human being, or, through inaction,
allow a human being to come to harm.
- A robot must obey the orders given it by human beings
except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such
protection does not conflict with the First or Second Law.
In 1985 he postulated a "zeroth" law
- A robot may not injure humanity, or, through inaction, allow humanity to come to harm.
