I am trying to implement a screw joint in gazebo PX4. I saw that there is the possibility to add such a joint in the .sdf file. However, I am unsure exactly how to do this, and more than that I am unsure how to add an appropriate plugin in the .sdf file (e.g. for regular motors the plugin added is the libgazebo_motor_model.so).
Does anyone have experience doing something like this ?
