PX4 now knows how to avoid obstacles on Intel Aero! The code is here: https://github.com/px4/avoidance
The documentation is in the repository link above and it only requires a standard Intel Aero.
Great! But why is it restricted to Intel Aero?Can it be ported to other platforms?
I wouldn't know since when ROS nodes are limited to specific airframes - so no, it is not limited to Aero. You can use any drone with a suitable depth sensor.
