 Introduction  

  Isaac Asimov popularized the term robotics. Asimov is a visionary who envisioned in the 1930’s the positronic brain for controlling robots. He invented the three laws of robotics:

•A robot may not harm a human  through

 action or inaction, allow a human to come to

 harm

•A robot must obey the orders given by

 human beings, except when such orders

 conflict with the First Law

•A robot must protect its own existence as long

 as it does not conflict with the First or 

 Second Laws
