Great work!
Where is the documentation of VIO and obstacle avoidance ?

For Aero and obstacle avoidance:

For Snapdragon with VIO:

@LorenzMeier avoidance code is a ROS node that flies in offboard, right? We are currently testing it and I wonder what is this 'Interface for external Obstacle Avoidance systems` that’s mentioned in 1.8 changelog…?

@LorenzMeier Thanks for the links. Are these tied to Aero and Snapdragon? Or, once can port the to other linux-based platforms? Basically I am interested to do both VIO and obstacle avoidance concurrently. Thanks again.

@Ekci That avoidance interface is pretty much a continuum - when you wrote your comment it was offboard - now it already evolved:

This will change further over the next weeks as we’re further improving it.

@Mzahana No, they are not linked to specific platforms.

@LorenzMeier Thanks for your reply. The problem is that even if they are generic frameworks, there is a lack of documentation on how to make the setup in general. What if one does not have a Snapdragon FCU? The avoidance documentation is good to some extent but lack details on the hardware side. Hopefully, the docs improve soon.

Thanks for the effort.
