The original laws of robotics
(The calvinian religion)
I. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
II. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
III. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
The zeroth law
(The giskardian reformation)
A robot must act in the long-range interest of humanity as a whole, and may overrule all other laws whenever it seems necessary for that ultimate good.
