What are the three laws of Robotics?

The three laws of Robotics formulated by Isaac Asimov are as follows:

1. First Law — A robot may not injure a human being or through inaction, allow a human being to come to harm.
2. Second Law — A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
3. Third Law — A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
