1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given 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 Laws.

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

His world ended; so he sat down to lunch.

The Eternal prisoners were too committed to the Myth to risk cooperation.

He is perhaps the most distinguished roboticist of our times.

There was a time when robots were the stuff of nightmares, dreamt of only by science-fiction writers.

He wanted to go; so did she. So they went, and it turned Earth into Mars.

Men have always used computational assistance.
