msgid "In order to \"wait until it has reached the desired height\", we need a conditional loop: the instructions inside the loop will be repeated only as long as a certain condition is true. The altitude of the bot is given by <code>position.z</code>. We already saw that <code>position</code> gives the position of the bot. And a position is given by the three coordinates x, y and z: the x-axis is the axis west-east, the y-axis is the axis south-north, and the z-axis is the vertical axis. Therefore we must wait while <code>position.z</code> is smaller than 20:"
msgstr "Pour \"attendre que le robot ait atteint l'altitude voulue\", il faut faire une boucle conditionnelle: ce qui se trouve à l'intérieur de la boucle se répète tant qu'une certaine condition est remplie. L'altitude du robot est donné par <code>position.z</code>. Nous avons vu que <code>position</code> donne la position du robot. Or une position est donnée par les trois coordonnées x, y et z de l'espace cartésien: l'axe des x est l'axe est-ouest, l'axe des y est l'axe nord-sud, et l'axe des z est l'axe vertical. Il suffit donc d'attendre tant que <code>position.z</code> est plus petit que 20 mètres, ce qui s'écrit:"
