The future is near

Isaac Asimov

A robot may not injure a human being or, through inaction, 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 First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Perhaps, very soon you will not be surprised by the robots in the home , in the office or in the hospital , and you will do with them all literally hand in hand.
