Running the ROS_quadrotor_simulator on ROS melodic and Gazebo9

[mSimon12]

Did anyone was capable of running ROS_quadrotor_simulator on ROS melodic and Gazebo9?

I have been trying it for days but as I solve a problem another shows up. I have the desire to execute a system compoused of a drone capable of mapping an external environment, so I need a 3d mapping and collision avoidance system. This package looks to be the most appropriate for my desire but I am a litlle stucked. Does anyone have an idea how to make it run or a tip about another packages that could be applied for my system?

Thanks guys!

Any update on this?

Hi @Makekihe,

Yes, I finally have been capable of controlling the quadrotor. For that I applied the content of the following repository https://github.com/tahsinkose/hector-moveit/tree/melodic-devel/src.

But at the moment I have made already a lot of changes on my code in a way that I can define a position for the quadrotor and I have made it possible to control more then one drone at a time. I am just making some updates and I hope to upload my solution on my repo on the next days.

Hi again @Makekihe,

I have uploaded my solution on https://github.com/mSimon12/multiple_quadrotors. There is still some things that I intend to improve, but for now it might help you.

Hi @mSimon12
Thank you very much for your reply. I'm kinda stuck in making this work, so I need some assistance.
Then trying to "catkin build" the repository which you're referring to (Tahsinkose's) then I receive Protobuff errors. Did you experience the same issue, and if so, how did you overcome it?

Hi @Makekihe,

To build it I use the catkin_make command. But as there is a lot of packages that it depends on, I suggest the first you go into the src folder and run rosdep install --from-paths src --ignore-src -r -y. It will install all the dependencies of my system.

Hopefully it will work. If not, it will probably be due to python dependencies and for that I will have to know exactly wich error occurs.

I hope it can help u ;)

Hi @mSimon12,

I see that despite trying both Tahsinkose's and your repository, then I receive the same type of error, so I assume that something is wrong with my system. I've used the rosdep install --from-paths src --ignore-src -r -y prior to the catkin_make command. The error is somehow connected to gazebo9 and some protobuf version which is not correct. The error is the following:

/usr/include/gazebo-9/gazebo/msgs/log_playback_control.pb.h:19:2: error: This file was generated by an older version of protoc which is incompatible with your Protocol Buffer headers. Please regenerate this file with a newer version of protoc.

In file included from /usr/include/gazebo-9/gazebo/msgs/MessageTypes.hh:61:0, from /usr/include/gazebo-9/gazebo/msgs/msgs.hh:35, from /usr/include/gazebo-9/gazebo/gazebo_core.hh:20, from /usr/include/gazebo-9/gazebo/gazebo.hh:20, from /home/ros/tahsinkose_ws/src/hector-moveit/src/hector_moveit_gazebo_plugins/src/fruit_generator.cc:1:

This error then persists for multiple msgs within the /usr/include/gazebo-9/gazebo/msgs/ folder, eventually leading to a failed build. Do you know how to resolve this problem?

Hi @Makekihe,

I have never faced this error. Unfortunately I don't know how to help you with that.

I will search for a solution and if I found something I will inform you.
