Hi everyone, 

I'm new to the VOXL platform and am considering to buy the kit to work on indoor drone navigation. I would like to start with setting up a simulation environment.

From what I understood from the software overview, VOXL Vision PX4 is responsible for autonomous flight. I'm wondering: Is it possible to run the VOXL Vision PX4 stack locally in order to develop indoor autonomous flight (for example, together with a Gazebo simulation)?

And in addition to this: to which extend is it possible to make modifications to the indoor navigation/SLAM software?

Thank you in advance!

@Jeroen-Minnema 
hi 
did u find any info about the SITL in the VOXL  that is supported and 
could u share any doc links or steps needed to set up the  SITL 
thank you

@Siddhanth SITL is not specific to VOXL because it runs on your host computer, not the VOXL. If you want to run a simulation with VOXL you need to use HITL. Here is the documentation for that: https://docs.modalai.com/voxl2-PX4-hitl/

@Eric-Katzfey 
ya HITL works but can SITL work on VOXL 2  like using our system's  MavRos?

@Siddhanth I guess I don't understand what you are trying to accomplish. SITL runs on the host computer. HITL runs on the VOXL. If you have a MAVROS application running on VOXL and you want to test it against PX4 you can use HITL. Or you could run your MAVROS application on the host computer and test it against SITL.
