Problem completing Basic usage with ROS

[AlessandroSaviolo]

Hi!

I've done all the installation steps as suggested by the guide "Basic usage with ROS", however I couldn't launch the file rotors_gazebo.launch (the launch was successful but the Flightmare gui wasn't able to connect to anything).. I've tried to launch rotors_gazebo_test.launch and it worked.

By commenting piece by piece of the rotors_gazebo.launch launch file, I've figured out that the problem was about the Gazebo nodes and the line https://github.com/uzh-rpg/flightmare/blob/master/flightros/launch/rotors_gazebo.launch#L27.

Is this line of code necessary for any purpose?

Update: By creating a new workspace with only this simulator, the problem is solved. Probably some conflict in the dependencies..

In order to use the PAMPC controller, the autopilot node in the launch file (https://github.com/uzh-rpg/flightmare/blob/master/flightros/launch/rotors_gazebo.launch#L72) must be skipped if the flag use_mpc is true (i.e., <group unless="$(arg use_mpc)"></group>)

Great. Happy that u addressed the issue.
For using the mode based controller, you can visit the rpg_quadrotor_control or rpg_mpc for more details.
