BACA JUGA : I just got a new toy from my uncle. My uncle is a sailor. He bought me a robot when he sailed abroad. I love this robot. My robot is very nice. It is about twenty centimeters tall. The colour of the robot is blue. The robot has a strong body. It has two big red eyes. It has two strong legs are covered with blade boots. My robot can be moved with two medium sized batteries. After inserting the batteries at the back of the robot body, we can make it move when we push the button behind its neck. The robot will move its left dan right foot in turn. It will move its two arms in turn too. However, the robot could not bend its feet and it moves forward only What is the main idea of paragraph three?
