Re: [Paparazzi-devel] Simulating ardrone2?

[Felix Ruess]

Hi Ben,

we are still missing a JSBSim model for a quadrotor in X configuration (like the ARDrone2).

Opened an issue about this: https://github.com/paparazzi/paparazzi/issues/595

It was my fault that I accidentally added the "simple_quad" as NPS_JSBSIM_MODEL to the ardrone2_raw.xml file.

And since the actuator names don't match nothing happens.

(top_left doesn't exist in the simple_quad.xml, and rightly so since that is for a + configuration)

I removed the line in ardrone2_raw specifying the model, since it is wrong and can not work.

Now you will get an error starting the NPS sim (JSBSim failed to open the configuration file: foo/paparazzi/conf/simulator/jsbsim/aircraft/ardrone2_raw.xml).

But IMHO that is better than NPS just not working for no obvious reason.

In the end you need to either provide a correct JSBSim file with the name of the aircraft, or set one explicitly via NPS_JSBSIM_MODEL.

See also http://lists.paparazziuav.org/nps-simulator-for-X-quadrotor-td13883.html

So, if anyone already has a JSBSim model for a quad in X configuration (or has the time to make a working one) it would be great to finally add one.

Cheers, Felix

If I try running a simulation of ardrone2_raw, it mostly works (I have to comment out the ubx_ucenter stuff), but the drone doesn't actually go anywhere - i.e. you tell it to start motors/take off, and it sits on the ground stationary.

Any idea where I should be looking to fix this?
