Just use Isaac Asimov's Three Laws of Robotics;

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2. Arobot must obey the orders given 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 Laws.

Put these laws in its permanent operating system so that if removed the robot will not function, that way it will be clone into any new robots.

And the movie IRobot is not like the book.
