my favorite exhibit

My favorite exhibit of discovery centre was little George-boy robot.He is a very intelligent robot which answers all of your questions.Miss Lee asked the robot, "what is 60 times 20". after a few seconds the robot answer "It is 1...2....0....0"than one of my friend named Darryl wee asked the robot"why are you botak". The robot answered "What is botak?". Darryl wee replied again "botak means smart". than the robot said " I am botak" everyone laughed. we asked him all sorts of question. Kian Wei asked if he ate hamburgers.he answered that robots did not eat and he liked to eat batteries. i was thinking if he did not consume anything why only batteries. if you have the solution please comment.

my father said that the robot had microphones that transferred to a station and the people there would answer.than the answer would come out of the robots mouth.i did not believe him as the robot needed charging . i thought that there was some kind of computer inside .please comment you suggestions.
