Three Laws

The Laws of Robotics and how they drive each plot.

1. First Law

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

2. Second Law

   A robot must obey human orders, except where they conflict with the First Law.

3. Third Law

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

4. Zeroth Law

   A robot may not harm humanity or, through inaction, allow humanity to come to harm.

The three laws were first stated in full in “Runaround” (1942); the Zeroth Law appears in Robots and Empire (1985). The laws are paraphrased here.
