The Three Laws are:
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey the orders given it by human beings except where such orders would 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 Laws.
I know the risk to human beings posed by artificial intelligences is a topic of serious study, of regulations imposed by some funding bodies, and of calls for legislation, but I do not know whether any such legislation has been adopted by a state or group of states.
