ISAAC ASIMOV ushered in the Robot Age with these superbly entertaining linked stories centred around the brilliantly simple concept of the Three 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 conflict with the First Law.

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

These laws are meant to ensure mankind's supremacy -even when robots seem more human than people. But what if the three sacred laws can be contravened?
