Hi Cris, some answers to your questions:

1. Ubuntu 18.04 for the time being (datasheet).
2. ROS 1 and 2 are easily installed. Examples are pending. Current SDK is documented here
3. The image sensors are available via gstreamer. We will have an IMU API soon.
4. Soft AP and station mode are supported (docs)
5. VNC/GUI - we have not tried this, but it's Ubuntu so it seems likely something could be tried
6. See datasheet for architecture. Yes, there is an SD Card slot.
7. The kit comes with everything shown here, the 5G modem is optional.
8. The 4G add-on, 5G add-on, Microhard add-on are all optionally supported.

posted a few basics in the docs https://docs.modalai.com/voxl-tflite-server/

You can see exactly where the image comes in her: https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-tflite-server/-/blob/master/server/threads.cpp#L105

Your understanding is correct, ModalAI's supported configurations are a result of Qualcomm limitations

It would have shipped with everything tested and working. What do you mean by "passed the wizard"?

The system was tested in VIO mode for 20 minutes before shipping. All drones are very sensitive to frame modifications, so this needs to be done carefully

• Were you able to fly successfully before frame modifications?
• How well does it fly manually? Have you looked at the logs in manual.mode for vibration?
• Can you please share a log of the VIO output?
• If you reset all of the software, you may need to recalibrate the cameras
• It looks like there are loose parts hanging off of the drone. VIO is VERY sensitive to vibration. Can you revert your frame modifications and try again?

Are you flipping the fastboot switch back? Your symptom is consistent with leaving the fastboot switch engaged instead of setting it back to normal after a few seconds

Might be worth watching the tutorial here if you're unsure

We do not have a thermal option available today, though the Flir Boson and Lepton have been integrated by customers in the past using USB

Stereo cameras need to be co-planar and mounted rigidly. Then they need to be calibrated. Otherwise you should be able to mount wherever convenient

You can see an example of how to write telemetry on top of a video frame here

Thanks for posting the ssl fix. We're looking into this. We don't typically use rosdep for anything. Is there something specific you need to get working?

A more traditional ROS experience is easy to achieve running Ubuntu in a Docker on VOXL : https://docs.modalai.com/docker-on-voxl/

For VIO use voxl-inspect-qvio

For GPS use voxl-inspect-gps

The source code for those is here

Can you please log and share some data using voxl-logger?

The command to log stereo and disparity is:

voxl-logger --cam stereo --cam dfs_disparity

That would help diagnose the issue

We are working on a new module now for OV9782. We'll contact you offline

We have posted the Sentinel CAD which has the flight deck embedded.

We have posted the Sentinel CAD which has some of the s500 components embedded. We don't have the s500 frame as is.

@serge did you try running voxl-configure-extrinsics and select the option for Seeker/VOXLCAM ?

Probably a rabbit hole, but you could try to figure out where libuvc fails? Doesn't seem like there is a technical reason it wouldn't work

What if you used 2 processes? Would libuvc work with two separate voxl-uvc-server instances?

never mind, i see that's what you tried

Have you watched the tutorial here ? It helps show what the GUI is asking you to do

I assume you have seen this tutorial since you mention the docker image

Have you tried to upgrade cmake inside the voxl-mavsdk-cpp:v1.0 docker? If cmake version is the only blocker, you should be able to upgrade it to keep moving

We have a px4io board that will be in beta soon. It will enable more RC options. Do you have a specific protocol you are looking for?
