-- Si des commandes sont publiées sur `cmd_vel` (depuis la Kinect par exemple) après le lancement du fichier `ardrone.launch` et avant le décollage du drone, alors, après le décollage, de drone semble obéir aux commandes publiées avant le décollage.
+- If commands are published on `cmd_vel` (from the Kinect for instance) after the launch of `ardrone.launch` and before the takeoff, then, after the takeoff, the drone seems to obey to commands published before the takeoff.
 
-- Comme écrit plus haut, l’affichage des informations reçues du drone sur `keyboard_cmd` n’est mise à jour qu’à l’occasion de l’appui sur une touche, et peut donc rester fixe quand on n’utilise pas la commande au clavier.
+- As written above, the display of navigation data on `keyboard_cmd` is only updated when a key is pressed, and can therefore stay fixed when the keyboard commander is not used.
 
-- Le décollage/atterrissage n’est pas possible à commander avec la main. Il faut utiliser le clavier (`keyboard_cmd` ou `rostopic pub`) à la place. Il est possible de de remédier à cela en créant deux nouveaux seuils, minimaux et maximaux, pour la hauteur de la main : une main très basse ferait atterrir le drone, une main très haute le ferait décoller.
+- The takeoff/landing is not controllable with the hand. The keyboard must be used (`keyboard_cmd` or `rostopic pub`) instead. We can correct this by creating two new thresholds, minimal and maximal, for the hand height : a very low hand would make the drone land and a very high hand would make the drone take off.
