Japan has more of these robots than any other country. The police also use a lot of robots to take apart bombs and stop explosions. In America,police used one of their robots to take a gun from a man,so they could arrest him. Robots even go to other planets. The Pathfinder spaceship went to the planet Mars. It carried a little robot that looked like a toy truck, which moved around to study rocks. It worked very well. Soon there will be robot cars and aeroplanes, and robots that clean floors and windows. In the future we will see robots everywhere.
