Programming and Theory

Have you ever had to do something over and over again? To write a word 50 times or 100 times? To carry several boxes one by one up the stairs?

When you notice that you have several repeating instructions in your program, you can put them in a loop and shorten your program without affecting the time for execution. You can use only three blocks and make your robot go around the room for an hour and a half or even more!
