Three Laws
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 the orders given to 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.
