There was a team of scientist. They were trying to make a fast robot. They used the best material to make that robot. Finally, they test the robot. Everything was fine until the final test. In this test, the robot had to race with two fastest scientists but the robot was slower than the scientists! Although they ran quickly, they were still not making enough progress. One of them said: “Why don’t we base on a cheetah?”. That was a brilliant idea! They started to remake and improve it. At the test, it ran as fast as a cheetah.
