@Robbie-McCue yes this worked thank you so much Robbie!!

@owf226 As soon as PX4 thinks it has taken off then it is trying to level the drone but can't since there are no propellers on the drone. So, it keeps increasing the speed of the motors on the side that needs to come up. That all seems normal to me.

@Rupesh Apologies for the late reply It looks like there’s an issue with how the AprilTag system is relocalizing the drone. In my tests, the z-value appears to be misinterpreted, which could explain why your drone was climbing in altitude to correct its height estimate. We’re actively working on a fix.

@greg_s Great! Sounds good

Hi @QSL OK, keep us posted! Any, for any new issues, please be sure to start a new forum post so it is seen by the team. Thanks!

@fhaltmayer It's not something we've explored

@crowley stinger is our FPV drone solution: https://www.modalai.com/products/stinger-vision-fpv?variant=48373207695664 We offer various levels of kit that can include goggles, transmitter, etc.

@dan64 Unsure if you have resolved this issue, but I am going to add some more information to anyone that stumbles across this. There was a bug in the voxl-mavlink-server setting and sending all System ID numbers to 1. The deb file below should solve this issue where the MAV_SYS_ID can be changed an reflected on the VOXL2. http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mavlink-server_1.4.12-202509181025_arm64.deb

Hi @VictorG Our team sent another batch out... FedEx tracking 884700036314 They claim Monday you should get it ... sorry for all these delays. We tried!!! I do not have visibility into our product shipment status, but this issue and experience has escalated the need for me to have that visibility, so I will explore that. We'll try better next time Keep me posted. Thanks!

@luisgb , all of ModalAI ESCs can be controlled via UART using two modes power : command 0-100% power, which controls the average duty cycle for that motor RPM : (requires calibration for the motor + propeller type): controls rpm directly Commands to the ESC are sent via UART and normally that UART port is connected to VOXL2 UART, which is mapped directly to the DSP. The DSP is where most of PX4 runs. If you are looking for the easiest integration / testing, you can connect the ESC directly the VOXL2 CPU (using non-DSP UARTs) and use either python or c++ code to interface to the ESC (or similarly from a Linux Desktop / laptop). It is also possible to communicate with the ESC while the ESC is connected to the DSP UART. This is how the voxl-esc tools work on VOXL2 (while PX4 is not running). This works by bridging the connection between the DSP and CPU and accessing the DSP UART from the CPU. However, this path has extra delay and is not recommended for any real-time feedback control applications. If you provide more information about your use case, I can suggest the best path. Alex

@holmeslice Regarding having the external flight controller, it's really only needed if the I/O limitations of VOXL 2 are a problem. For example, if you need CAN bus then you should probably use the external flight controller since VOXL 2 has no CAN bus support.

@Vinny Thank you for your valuable feedback. I’ll keep the points you mentioned in mind while doing the bench testing.

@gestrada1150 We have an experimental fork of betaflight running on VOXL 2 now. However, there are no official plans to support this.

@Daniel-Rincon I'm hoping you are still around as we might be having a similar issue. When you say documentation, do you mean these: https://gitlab.com/voxl-public/support/voxl-train-yolov8 What specific helpers did you add with what model conversions? (Reference: I also have a custom yolov8 model trained for an output of two classes.)
