The pipes that voxl-camera-server publishes should be accessible in a Docker. You should be able to access them that way inside of a Docker. A voxl-mpa-to-ros2 service would be a good addition, we don't have that implemented yet.

RE: RB5 Kit + SDK queries
Hi Cris, some answers to your questions:
- Ubuntu 18.04 for the time being (datasheet).
- ROS 1 and 2 are easily installed. Examples are pending. Current SDK is documented here
- The image sensors are available via gstreamer. We will have an IMU API soon.
- Soft AP and station mode are supported (docs)
- VNC/GUI - we have not tried this, but it's Ubuntu so it seems likely something could be tried
- See datasheet for architecture. Yes, there is an SD Card slot.
- The kit comes with everything shown here, the 5G modem is optional.
- The 4G add-on, 5G add-on, Microhard add-on are all optionally supported.

RE: Shipping to Australia
We have not had a problem shipping directly to Australia.

RE: Voxl - Snapdragon model and supported camera configurations
Your understanding is correct, ModalAI's supported configurations are a result of Qualcomm limitations

RE: ERROR: failed to start modalai vision lib
It would have shipped with everything tested and working. What do you mean by "passed the wizard"?

RE: High-Res Camera Blurry
The lens is fixed focus, but if you twist the little black part of the lens you should be able to focus.

RE: m500 cannot hovering with VIO algorithm
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?

RE: Unbricking fails due to "protocol error"
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

RE: stereo camera down
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

RE: How to run tf-lite-server on VOXL
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

RE: Video frames synced with telemetry?
You can see an example of how to write telemetry on top of a video frame here

RE: Can't find how to configure the hires camera
You can set the resolution of the preview stream in /etc/modalai/voxl-camera-server.conf

RE: VOXL FLIGHT connection to LuxF7HD
It is not something we have direct support for since the flight controller is built in.
Here is how you connect VOXL to an external flight controller: https://docs.modalai.com/how-to-connect-voxl-to-pixhawk/
The normal UART is not exposed on VOXL Flight, so you would have to modify the code on VOXL to use a different UART

RE: Issues with Docker, and WiFi connection
Why use Docker for this? voxl-logger is setup to do this for you already

RE: Using Sentinel Drone with IntelRealSense Depth Camera D435
@Jgaucin you can use voxl-portal to view the output of all of the image sensors on the drone. The Sentinel has forward and rearward stereo depth pre-calibrated and tested in the factory
https://docs.modalai.com/voxl-portal-cameras/
this might also be useful

RE: VOXL FLIGHT connection to LuxF7HD
You will need to change the code in voxl-vision-px4 to use a different UART. I don't think betaflight supports mavlink though as a control mechanism. What are you hoping to connect between VOXL and betaflight?

RE: Sentinel Drone Rangefinder
Hi Erik, thanks for pointing that out. It was a mistake, it has now been fixed as there are no CH-201 sensors
