Dear friends, This is my first post on the “discuss.px4” and I would like to get your guidance for the described problem in the thread title. I try to change the standard_vtol model’s appearance with my custom drone model which I am using “ROS Gazebo PX4” combination that I control my drone from R…

Which file are you editing to change the appearance?

[Screenshot from 2020-11-21 00-23-52] I found the cause but there is a strange problem. Go to /src/PX4-Autopilot/launch/mavros_posix_sitl.launch file and you will this line of code that directs you to /usr/share/mavlink_sitl_gazebo <arg name="vehicle" default="standard_vtol"/> <arg name="world" …

I still don’t understand why you have sitl_gazebo in /usr/share/mavlink_sitl_gazebo Did you try installing sitl_gazebo? $(find mavlink_sitl_gazebo) should not direct your path to /usr/share/mavlink_sitl_gazebo . If this is the case, your path is not configured correctly. To configure your path cor…

This “mavlink_sitl_gazebo” is generated itself when I had installed PX4 from your given link already. Official PX4 mavros_posix_sitl inside code which this “mavros_posix_sitl” only search for ROS Path which it was generated by PX4 itself. It seems like noone had ever tried to change the default dro…

After lots of testing and trials and checking the code of default PX4 drone model too, I found the main cause of everything… x8_wing.dae size which is the main body frame of “standard_vtol” drone model is too huge, it is like a mega VTOL drone model… (model path is here /home/aykut/src/PX4-Autopilot…

Good to see that you are making progress! It seems like noone had ever tried to change the default drone models with their custom models to fly by using the default drone control with ros px4 gazebo; because there is zero information in internet. I don’t think this is true. I think the reason yo…

Thank you Jeyoung. Yes you are right - this drone’s model modification is mainly related to gazebo but when I had compared the arducopter drone design in gazebo and the px4 drone design in gazebo are not so similar while preparing the “.sdf file in the models section of gazebo”. For these subjects, …

Would it be possible to write your experience down, and contribute a step by step guide to the PX4 documentation? https://github.com/PX4/PX4-user_guide This will help people to not suffer with the same issue you had, and I believe you are the best person to write it since you are fresh from sufferi…

There are a lot of people interested, how to add/modify models in gazebo and use px4 for control.Looking forward to someone can provide some documentation, that would be great! :grinning:
