      Hello ModalAI Team,

      I am still trying to get the navigation working with my team's Starling 2.

      system-image: 1.8.06-M0054-14.1a-perf
      kernel: #1 SMP PREEMPT Wed Oct 22 04:13:18 UTC 2025 4.19.125
      hw platform: M0054
      mach.var: 1.0.1
      SKU: MRB-D0014-4-V1-C27-T8-M22-X0
      voxl-suite: 1.6.2

      I have updated the drone to the latest voxl version 1.6.2. I am able to fly the drone in position mode and figure 8 mode.

      I few the drone around for a couple of minutes in our testing room gathering map data. I then switched the drone into offboard_mode: trajectory. I planned a point and saw the projected path drawing a simple straight line. There are not obstacles in the way to navigate around/avoid. The drone just flew directly at the grown instead of following the path. Is there anything I should try software/settings-wise to try and get navigation working? Is there anything about the layout/appearance of a room that could cause this? Please see the attached image.

        Hello ModalAI Team,

        Please let me know if there is any further information needed. So far, I haven't had the drone successfully navigate in trajectory in any version of the VOXL SDK I've tried (1.4/1.5/1.6).

          Hey @greg_s,
          Can you post your voxl-logs and flight logs?

          Thanks

            Hello @ApoorvThapliyal,

            I put the log file here: log100.ulg on Filebin.net
            I also put the the output from voxl-vision-hub --debug_offboard suggested by @Cliff-Wong in another post in another upload here voxl-vision-hub-log.txt on Filebin.net.

            When I attempted the flight, the drone appeared to fly to the correct X and Z coordinates, but it was close to the floor and well below the correct Y coordinate.

            Here are a couple of picture of the map and projected route:
            plan1.jpg
            plan2.jpg

            And a couple of the map after the drone tried to navigate and ended up below the point:

              For convenience I took out the section that has the trajectory from the voxl-vision-hub logs:

                  Hey @greg_s
                  I just wanted to confirm, are you dragging the planned point to the height desired? By default, simply clicking on the map will generate a point at height 0.
                  Let me know, thanks

                    Hello @ApoorvThapliyal,

                    Yes, I am dragging the point up and panning the camera around to ensure it is roughly the same height as the drone. The line drawn for the path is pretty straight and at the correctly level. The drone just ends up flying down below the point after I have move it.
