Why spawn_quadrotor.launch crashes ?
Hello everyone, I am using the tum_simulator package because I have to work on the AR Drone 2.0 (from Parrot).
I am using gazebo 8.1 and ROS kinetic on Ubuntu 16.04 and when I launch a gazebo world (for example : "roslaunch gazebo_ros empty_world.launch" ) and then I use the command : "roslaunch spawn_quadrotor.launch", the drone appears but after a few seconds, the simulation crashes and this error message appears (In the terminal where I launched the empty world) :
Error [Element.cc:684] Missing element description for [driftFrequency] Segmentation fault (core dumped) [gazebo-2] process has died [pid 20798, exit code 139, cmd /opt/ros/kinetic/lib/gazebo_ros/gzserver -e ode worlds/empty.world __name:=gazebo __log:=/home/vernet/.ros/log/095b68d8-5d9b-11e7-b26c-000c29ea9e6c/gazebo-2.log]. log file: /home/vernet/.ros/log/095b68d8-5d9b-11e7-b26c-000c29ea9e6c/gazebo-2*.log
PS : I have already tried to use directly the ardrone_testword_launch (the drone should appears directly in a world) but it also crashes, and when I commented the part of the file supposed to generate the drone, I can open the world without the drone..
PS 2 : Sorry for my English, I am not bilingual.
