    Hello. I purchased a Starling 2 Max development drone and when attempting a first flight test I discovered that one of the batteries arrived entirely dead. I was curious if there was a way to receive replacements, and if this falls within replacement territory. I contacted the support email and was directed here. I can provide more information if needed.

  • Do you have a great idea for our products you would like to see implemented?

    Hello everyone, I am looking for some expert advice on a VOXL 2 companion computer setup for a long-range platform. I have two main integration challenges: Challenge A: VIO at Higher Altitudes To solve the motion blur and pixel density issues at higher altitudes, I am planning a 6-camera configuration. I want to use 4 downward-facing sensors (2 daylight + 2 IR) equipped with narrow-angle lenses, alongside 2 standard wide-angle sensors (front and rear). Could you advise on the best supported sensors (e.g., IMX series) for this? Has anyone successfully tuned the voxl-qvio-server for narrow-angle lenses, and what were the altitude limits you achieved? Challenge B: LAN Integration & WireGuard The payload data flow will be: External RTSP Camera -> Ethernet -> VOXL 2 (WireGuard encryption) -> Ethernet -> Digital RX. Because VOXL 2 lacks multiple LAN ports, I will need a miniature industrial Ethernet switch. Does ModalAI have any tested hardware recommendations for this? Furthermore, what is the best practice for routing this VPN traffic through the VOXL 2 Ubuntu environment without bottlenecking the CPU? We are currently evaluating the VOXL 2 for a broader fleet deployment and want to ensure the ecosystem can support this custom optics requirement. Any feedback on off-the-shelf solutions or standard configurations for this use case would be greatly appreciated. Thank you!

    @nl_vdi , if you log into developer.modalai.com, you will see the CAD models. the latest model we have is: D0012-4-V3-C28-M36-T7-K0-Starling2-Max-V3-20260317.step [image: 1781036132877-376bf0dd-494a-4bf1-8d92-1b2d91afb83d-image.png]

    It looks like configuration 28 is what you're looking for with the standard 3840x2160. That's the resolution I've tested the 214/377 sensors with.

    @ShauliXtend said in Building a custom docker image with VOXL libs: on the VOXL itself you use 32bit libraries while the system is 64bit Yes, unfortunately the QVIO algorithm is proprietary to qualcomm, we don't even have the source, just the 32 bit binaries that they've provided. maybe there is a way to still use the 32bit file You'll need to compile a 32-bit program to use a 32-bit library, there's unfortunately no way around this without some sort of inter-process communication (hence our standalone qvio-server)

    @Alex-Gardner So I guess I can't really do much to debug this (without knowing more about the proprietary implementation), true? Point being... if there is documentation you can share, I'll gladly dig into this.

    Non standard camera configuration on VOXL running 4.0.0-0.9.4

    Thanks for the hint @Alex-Gardner, I tried two separate modules on 3.3.0, 3.6.0, and 3.8.0 and they worked just fine, it is only with system image 4.0.0 and voxl-sdk 0.9 that neither one works which makes me conclude that it's not the sensor but something with the software. Also both modules works just fine when run by themselves, it is only in conjunction with other sensors like stereo/tof that the hires is causing issues.

    @Chad-Sweet Thanks for your response. I apologise for the late response. As you correctly pointed out, we resolved the issue after a re-calibration of the front stereo pair in natural lighting and by further tuning the 'blur_size' and 'post_median_size' parameters in the DFS server config file. Now the data reflects actual physical obstacles quite reliably.

    @Youngjoo-Kim J18 is the port normally used for the UART based ESC. It is connected to the DSP, not the Linux processor. You cannot directly access it from Linux. Why do you need to run Mavlink over a serial port? We support and recommend using UDP.

    You should be using docs.modalai.com , the beta-docs are only published for specific, pre-release components. You cannot plug image sensors in where ever you like. You need to follow a supported configuration here: https://docs.modalai.com/voxl2-camera-configs/

    Hi Chad, Thanks. One more question: Once new features are necessary during development or feasibility check, how to get ModalAI direct support? by contract or only through ModalAI forum? Best Regards, Dan

    Hi Jose, there's really not enough information for us to help here. What flight controller are you using? how are you connected? What did you change to get it into this state? that error implies you do not have GPS connected, or it is not outside to receive position information

    You need to calibrate the thermal camera to generate the intrinsic. There is no off the shelf way to do this. You will need to create a to-scale checkerboard that the sensor can see

    Apriltag Relocalization with GPS?

    Modules such as Precision Landing in PX4 perform a indirect correction using relative camera coordinates translated to the global frame upon identification if the "tag/marker". I suggest you take a look into the Precision Landing module of px4 as an example in solving your problem. Of course that is using the IR markers available out there. Now we have internally modified that module for april tags in the landing case as well that will be available shortly. This method corrects the drone relative to actual ground truth (i..e the ARtag/IRTag), but does not correct the Global Frame position itself as its used as a relative offset to correct its setpoint position. That offset could be used to correct the global frame position itself (doesn't necessarily exist in PX4), but then again it would be better to transmit the actual GPS position of the tag to account for the curvature of the Earth, etc... and then calculate a proper offset.

    I tried the link you provided,the ECS is not intalising and ardupilots firmware and voxl is not able to communicate with the px4. Also stats provided in voxl portal about px4 there is not available. Is it possible we meet on a call on any meeting platform, So that we can solve this issue easily? Thank you

    Hi @Alex-Gardner I'm trying to accomplish the same thing as the OP but I'm running into some problems (my thread: https://forum.modalai.com/topic/1703/non-standard-camera-configuration-on-voxl-running-4-0-0-0-9-4). When connecting the stereo to J3 and hires to J4 voxl-camera-server -l outputs only two cameras which are the stereo, it does not recognize hires unless its on J2 but that has its own slew of problems which I've gone into more detail in my thread. Any help with this would be appreciated.

    @TasnimBas Glad we can help. Our team says this: "The injection molded plastics from the S500 frame are advertised as being glass-fiber reinforced nylon", so not sure if that helps you, but we do not have a material spec sheet to get the temp coefficients you are after. Maybe that description can get you close!

    No, but there should be no difference to any other Debian system. I think if you Google it, you should find what you are looking for. From Google, I found this result which looks promising https://docs.ros.org/en/dashing/Installation/DDS-Implementations.html Obviously, we have not tried this
