3 Laws of Robotics
A robot may not injure a human being or, throughinaction, 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 FirstLaw.
A robot must protect its own existence as long as suchprotection does not conflict with the First or SecondLaw.

Summary
Robots are based on computer technology
Higher production capacity can be achieved
using robots Higher quality products are manufactured
using robots
