Robots were created in the form of human beings and function with the accordance to the following 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 Law.
Story illuminates a problem encountered when a robot interprets the three fundamental Laws and something goes awry. One robot questions the reason for his existence. Another feels a necessity to lie. Yet another has an ego problem. The later stories introduce the reader to the Machines, powerful computing robots without the typical humanoid personalities of the working robots, that control the economic and industrial processes of the world and that stand between mankind and destruction. These stories introduce some fascinating and sometimes unsettling ideas: where does one draw the fine line between intelligent robot and human? Can man and robot form a balanced relationship? Can a robot's creator reliably predict its behavior based upon its programming? Can logic alone be used to determine what is best for humanity?
