@ApoorvThapliyal, with the setting you provided, I tried flying with propellers on in offboard mode. Once I armed and switched to offboard mode, the drone took off and stayed at around 10 cm height for 10 seconds. During that time, it didn't detect AprilTag and failed to align, as the height was too low for detection. However, after 10 seconds, it suddenly began to gain height, and as it approached the ceiling, I took control and landed. From the log file, we can see that the drone was attempting to align its X and Y positions with AprilTag; however, the issue was that the Z setpoints continually decreased. Can you please help me solve this?

Additionally, it would be more beneficial if we could run it using MAVSDK and customize it for our specific code.

@ApoorvThapliyal Thank you for your reply.
I tried voxl-vision-hub --debug_fixed_frame while showing AprilTag to the tracking camera with different orientations, but got some warnings about qvio.

Since this was a warning about qvio, I checked voxl-inspect-qvio, and it was working okay.

Additionally, I wanted to integrate AprilTag Localization with voxl2_takeoff_land.py. Is it possible to make it work if I add the following code between the 'takeoff' and 'landing' commands?
try:
await drone.offboard.set_position_ned(PositionNedYaw(0, 0, -1.0, 0))
await drone.offboard.start()
except OffboardError as e:
print(f"Offboard start failed: {e._result.result}")

await asyncio.sleep(20)

print("-- Stopping Offboard mode")
try:
    await drone.offboard.stop()
except OffboardError as e:
    print(f"Offboard stop failed: {e._result.result}")

I tried to operate it without propellers and got the following logs in PX4.

The set points appear to be at the origin instead of those defined by AprilTag. Can you please help me with this?

Hi,
I'm using Starling 2 Max drone. I'm trying to localize the drone with AprilTag. I followed all the instructions from the ModalAI documentation, but cannot get it to work. I feel like the instructions for Relocalization are incomplete. The voxl-inspect-tags is working perfectly, and voxl-inspect-services also shows everything working. I also changed the offboard mode to "follow_tag" as shown in the figure below. Can anyone help me with how to proceed? Or i must use docker and run the script file? If so, is offboard_follow_tag.c safe to use? Because the documentation says "offboard_follow_tag.c: (may be outdated and no longer functional)".

@Alex-Kushleyev Thank you so much. Now the camera is working. Previously, during the installation, I selected a second option of continuing the installation process with the option to keep the same configuration, which was wrong decision. It did not gave me an option to choose my drone name before. But, now that i selected the first option that give questions along the way, i was able to select the correct options for my drone as shown in picture below.

@Alex-Kushleyev Do you mean the mach. var.? Mine seems to be 1.0.0. So, which latest SDK version should I be installing?

@Alex-Kushleyev Thank you for your reply. I did voxl-configure-mpa multiple times, but every time it fails to make the camera work. Also, I've tried multiple options in voxl-configure-cameras like 06, 02, 03, 19, but still won't work. I know that mine is D00012, but can't find it the options. I also cannot find C27, C28, C29 etc. in the options.

Hi,
I'm using a Starling 2 Max drone with ToF. After I installed the VOXL SDK 1.5.0, all the cameras stopped working.



Can anyone please help me solve this issue?

@Alex-Kushleyev Thanks

Hi,
I followed the steps in https://gitlab.com/voxl-public/voxl-sdk/third-party/voxl-opencv, but when i try the second step "voxl-cross(3.3):~$ ./install_build_deps.sh qrb5165-2 dev", I get an error because that file is not included in "https://gitlab.com/voxl-public/voxl-sdk/third-party/voxl-opencv.git". I'm using voxl-cross(4.4) instead of 3.3, because V3.3 is not available. Can anyone please help me with that? Without that file, many .hpp files are missing.
