I have no brain but I can speak.
Sometimes all I say is Beep.
I am made of tin but I am no man.
I will try to help you if I can.
I may break but I won’t die.
I am often heard after I.
(The fourth line is a reference to Isaac Asimov’s law of robotics, which says robots can not hurt humans and the last one is a reference to his book/movie I,Robot)
