[JdeRobot] Problem launching ArDrone + Introrob_py

[JoseMaria Cañas Plaza]

Hi Julio,

even if you see the robot in gazebo's GUI the plugin may be not
properly loaded. If the plugin is not loaded properly then it will not
start the ICE server and any ICE client will fail, even if the ports
are well configured. Check it running gazebo with the verbose flag,
then you will get more about the inside of the problem. The same
directions you used but with

gazebo --verbose ArDrone.world
