Loading a custom aircraft model to jsbsim bridge #58

Open oricabel opened 2 years ago

oricabel commented 2 years ago

Hello, I have an aerodynamic model that I wrote in .XML format and I want to simulate it using the bridge, but I don't understand how. I tried to copy the model's folder into a folder with the rest of the models that work (Rascal, Malolo, etc..), but when I try to run it the same way I run the others, it doesn't even recognize the model exists.

It is obvious I'm missing a few steps... can anyone please help?

@oricabel Could you elaborate exactly how you were trying to run your custom model and how it is failing?

oricabel commented 2 years ago

I tried to find the locations of other, working models (rascal, malolo) and add my model in the location, now I am sure this is not enough, perhaps the program needs to "know" that there is a new model, and if we ask to run it, it should use the models files. When I try to run my model, it just says that it does not recognize it, as if I wanted to run somthong that doesn't exist.

@oricabel Please share exactly how you "tried" and what the "not recognized" error is. Otherwise it is hard to know what is missing from what you are describing

I took the model's folder named "Aeolus" (which contains it Aero model, setup file, engine, etc...) and pasted it to the following paths: ~/PX4-Autopilot/Tools/jsbsim_bridge/models/ ~/PX4-Autopilot/src/px4-jsbsim-bridge/models/ ~/PX4-Autopilot/Tools/flightgear_bridge/models/ These paths are where I found folders of other models (rascal, etc...).

I tried to run the simulation with the custom model using: "make px4_sitl jsbsim_aeolus"

And received: "ninja: error: unknown target 'jsbsim_aeolus' Makefile:235: recipe for target 'px4_sitl' failed make: *** [px4_sitl] Error 1"

For reference, if I just write some letters: "make px4_sitl jsbsim_dgf" I get the same error.

I hope the description here is sufficient.

@oricabel You also have to add the custom model name in the cmake target list in the file _PX4-Autopilot/platforms/posix/cmake/sitltarget.cmake in the portion _set(modelsjsbsim. After this, you have to add a airframe for the model in the airframes directory.
