The series/movie is based on the novels written by Isaac Asimov (I've been a big fan of his work since I was a kid!)
Isaac Asimov made the three laws of robotics, which were used extensively in his work (and in this series as well):
- A robot may not injure a human being or, through inaction, allow a human being come into harm.
- A robot must obey orders given to it by human beings, except where such orders 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.
