South Korea is to draw up a Robot Ethics Charter.
ASIMOV’S LAWS OF ROBOTICS
A robot may not injure a human being or, through inaction, allow a human being to come to harm.
A robot must obey 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 Law.
