Unable to takeoff using /uga_tum_ardrone/com topic #4

Hi, I am trying to set up the uga_tum_ardrone by starting to takeoff the drone. I start as it is stated in the readme: $ roslaunch uga_tum_ardrone ardrone_driver.launch $ roslaunch uga_tum_ardrone uga_tum_ardrone.launch and then I try to send the takeoff command to the /uga_tum_ardrone/com topic by doing: $ rostopic pub /uga_tum_ardrone/com std_msgs/String "c takeoff" but nothing happens. Am I missing something obvious? I can command the drone without problems using the GUI, so I really do not understand what I am doing wrong. Any clue? Thx in advance. Josep Arnau

Hello,

You actually have to start the system first, by sending "c start" before anything else. That's problem with the documentation that needs to be fixed.
