Avoidance Question



  • Hello! Just reading through your documentation on Obstacle Avoidance .. it seems to imply that you just need to run a calibration and turn it on in /etc/modalai/voxl-vision-px4.conf

    When I do all this, I don't seem to be getting any meaningful obstacle data from the debug mode or in QGC. I assume that I also need to compile and run the avoidance ros node on my own apart from these instructions?

    Can you please clarify?
    Thanks!



  • Hi Kip, right now that feature is only implemented in voxl-suite 0.2.0 and earlier. We're working right now on implementing for voxl-suite 0.3.5



  • I'm not so sure which one I'm on:

  • Hi @Chad-Sweet it appears that I am on voxl-suite 0.2.0 as indicated above. However, if QGC reports that avoidance system is unavailable and the vehicle will not arm. If I run

    voxl-vision -s
    

    I can see the obstacle debug info on the terminal, also I set

    "en_voa":    true,
    

    Any suggestions as to what I am doing wrong?
