"This exercise is very similar to the previous one. The bot must move exactly in the same way, but when writing the program, you must use a new concept that is extremely important in programming: <a cbot|var>variables</a>.\n"
"We saw that all the pads are at a distance form each other of 20 meters. And all the rotations performed consist in 90 degree angles. Instead of rewriting the same values over and over again in the program, we can store them in a variable: "

"Il n'est pas forcément facile de se souvenir qu'il faut utiliser <code>90</code> pour virer à gauche et <code>-90</code> pour virer à droite avec l'instruction <code><a cbot|turn>turn</code></a>. En stockant ces valeurs dans deux variables que l'on nomme <code>gauche</code> et <code>droite</code>, l'écriture devient plus simple."
