@Bilal-Hussain , can you please clarify:

"if it's possible to step up voltage." - what do you mean? which voltage?

Regarding maximum current per motor, the mini ESC can output continuous current at least 10A per channel at 15-16V input battery voltage (we tested at 15A+ with direct cooling from the propellers). The mini ESC is recommended for small drones 300-500g range or small fpv drones (300g). Maximum input voltage is 16.8V (4S LiPo). This ESC is very small, so when you are building a new drone, you should conduct tests to monitor the ESC temperature which should to stay below 80C. If you are exceeding that and getting close to 100C, it is a bad sign. The ESC should be rated to operate at least 110C but if you are getting that hot, it is a sign that something is wrong (motors are drawing too much current for the ESC or insufficient cooling).

We typically use the mini ESC in the drone designs that use less than 5A per motor during hover and may reach up to 15A per motor at full thrust for some time.

The ESC reports temperature via UART feedback and it is available in PX4 esc status message.

We will update the current specifications in the datasheet (https://docs.modalai.com/voxl-mini-esc-datasheet/)

@Wei-Cui-0 @Eloi @SMRazaRizvi Hello, the cover form the Sentinel Flight Deck can be used interchangeably with the RB5 Flight Deck, as long as you are not using the ultrasonic sensors. Here is the link to the Sentinel CAD: https://storage.googleapis.com/modalai_public/modal_drawings/Sentinel_Drone_STEP.zip

@Alex-Kushleyev Ohh.

Yes please let me know how can I. I'm afraid I'll be needed spare parts for my research.

@Alex-Kushleyev Thank you! I'll look through the code a bit harder to make sure I'm not doing anything silly. I'll let you know if I have any more questions.

@Eric-Katzfey Thank you so much for the information.

@Kris a 3 second delay is very likely on the client side with buffering, or network backup. RViz is not an optimal way to achieve low latency video as ROS typically sends an uncompressed, full frame. The QGC video display has much lower latency and uses a compress RTSP stream.

@Kashish-Garg-0

You might be able to find the raw lens parameters here

The PMD libraries use those calibrations to adjust the point cloud data, so it may be corrected prior to being published as a depth map or point cloud. We have not used those lens parameters directly ourslves.

I would like to add that the auto-tune feature is not a turn-key fix all feature. you still need to tune filters, and do a bit of tuning yourself before initiating auto-tune.
auto-tune gets you the last 20% of tuning, you have to do 80%. and even after that it still might need some adjusting based on how you want your UAV to fly

@19bpl At the very least you need to be able to ping the QGC computer from VOXL2 and VOXL2 from the QGC computer before attempting anything else.

@Alex-Kushleyev Thank you, appreciate the detailed response! (I completely missed this message, I thought I'd get a notification but I forgot to subscribe to notifications)

you can see how the point cloud data is received in our voxl-mpa-tools :

https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/tools/voxl-inspect-points.c . This is a very simple example, but you can use it to make your own application.

this example shows how you can inspect 6DOF pose : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/tools/voxl-inspect-pose.c (i believe you need voxl vision hub running for that)

@Darshit-Desai , if you don't have the emulator docker, the next best thing to do is to build the package right on target, using ./build.sh native option. please try.

@camcam089
Hi, I am also trying to work on doing audio streaming over USB.
I am curious if your code is open in github or somewhere else.

@frafrat ,

You would need to run voxl-camera-server that comes with SDK 1.2 . You can grab a deb package of recent voxl-camera-server but it has other dependencies, so other packages will need to be updated from sdk 1.2. it could be a mess, but you can try it.

http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-camera-server_1.9.0-202403211533_arm64.deb

when you install it, if there are unmet dependencies, dpkg will tell you. and then you will go down the rabbit hole to satisfy those dependencies and installing newer packages (you could do it by updating apt sources to use dev) : modify /etc/apt/sources.list.d/modalai.list to use dev instead of sdk-1.1 (and then apt-get update and then apt-get install <package> to get the newer version. Or you could pull the packages manually from voxl-packages site.

I know for sure there is one dependency that is not in voxl-packages, which is the TOF processing library. I will check how you might be able to get it.

Did you at least try to use the TOF sensor with SDK 1.2?

@ggiacalone Yes, this will have been flown before shipping. Any chance the Receiver was knocked loose somehow? Your description implies maybe a connection issue?

Can you grab a screenshot of the QGC RC configuration? Maybe the protocol was changed somehow?

@Riccardo-Franceschini is there any chance that you could send me your docker image (or maybe the layers that are used to install the realsense "software")? I've been struggling to get the realsense in a ros2 docker working. The only think that worked for me is a docker image based on Alpine.
