[problem] roslaunch interface_nbvp_rotors flat_exploration.launch

[Zeta611]

The current master branch does not seem to have firefly_vi_sensor.gazebo file..

Thank you for pointing out. I am working on a solution that will solve this divergence problem and also prevent similar ones in the future.

@birchera Thank you for the reply. I am really looking forward to run your nbvp ROS example ASAP.

@won13y For now, simply use the version of rotors_simulator before April 4th. https://github.com/ethz-asl/rotors_simulator/tree/4f763acdec2225809b9937adca0740730d53ddc1 worked for my case.

@Zeta611

Thank you for the reply. I would really appreciate.

I tried to run the the version of rotors_simulator before April 4th, but

https://github.com/ethz-asl/rotors_simulator/tree/4f763acdec2225809b9937adca0740730d53ddc1

The problem occured

In order to run the following sections

Basic Usage

Launch the simulator with a hex-rotor helicopter model, in our case, the AscTec Firefly.

$ roslaunch rotors_gazebo mav_empty_world.launch mav_name:=firefly

it does not include mav_empty_world.launch in launch folder of rotors_gazebo

mav_empty_world.launch

Would you please let me know how to run the nbvplanner example?

I was able to run successfully RotorS Gazebo Simulator,

but what I really want to run is the nbvplanner as described in following paper and wiki

Receding Horizon "Next-Best-View" Planner for 3D Exploration

https://github.com/ethz-asl/nbvplanner/wiki

In particular, following command need to be excuted in order to run the nbvplanner

roslaunch interface_nbvp_rotors flat_exploration.launch

but, as I described above, the above command produces the failure due to firefly_vi_sensor.gazebo file

Thank you in advance!

[Zeta611]

mav_empty_world.launch

does not exist in this version, but

roslaunch interface_nbvp_rotors flat_exploration.launch

should be executed fine. Have you tried rebuilding your catkin workspace? Make sure to build it in release mode using:

catkin config --cmake-args -DCMAKE_BUILD_TYPE=Release

@Zeta611 Thank you very much

I tried to execute the the version of rotors_simulator before April 4th,

https://github.com/ethz-asl/rotors_simulator/tree/4f763acdec2225809b9937adca0740730d53ddc1

roslaunch interface_nbvp_rotors flat_exploration.launch

It finally works! Thank you!

I hope that Master branch is also available for me to execute nbvp planner ASAP!

I really appreciate your help!

[Zeta611]

@won13y, I’m happy to hear that it works! :D

[birchera]

I am glad to hear you found a solution in the meantime. #5 should now do the trick.

Thanks for reporting!
