Sentinel flips during takeoff
-
@stevedan One quick thing you can try is to blow some compressed air through the motor. If there is some debris stuck inside the motor then the air could blow it out.
-
@Eric-Katzfey I have tried that and it seems not to work. As you said, this happens when during the arming, one of the propellers does not spin fast enough like the others. It happens randomly on both drones.
-
@stevedan Okay, thanks for trying that. We are still discussing internally on best next steps.
-
@Eric-Katzfey Just adding more information, this also happens sometimes in manual flight, but it take time for the motors to get to speed during arming.
-
@stevedan Okay, thanks! And thanks for your patience. We are locating a drone here in San Diego that exhibits the same behavior so we have a way to reproduce and resolve the issue. One option is to send some new motors but our lead ESC engineer believes he can resolve this with an update to the ESC firmware.
-
@Eric-Katzfey Thank you for the fast response. Let us know because there is a bit of urgency to use the drone and there wont be enough time to procure another due to lead time. We currently have 3 new drone and plan to procure more but this is hindering us from doing so.
-
@stevedan Okay, understood. We are testing some new ESC firmware now and hope to have an update for you early next week.
-
@stevedan We will need to walk you through the procedure to update the ESC firmware. In order to do that we need to know what software you have running on the drone now. Can you paste the output of
voxl-version? -

@Eric-Katzfey Is it possible we can set a time that both of us are available to speed up the process given that your timezone is different from mine?. like 6pm spain time?
-
@stevedan Would you be willing to just move to our latest software platform release to resolve this rather than trying to get new ESC firmware setup in the release that you have now? It is in beta but we can give you access to it and it should solve your flipping issue.
-
@stevedan I sent you a link to the new platform release in email if you are interested in trying it out.
-
@Eric-Katzfey I can test this release and see if it solves the problem. When would this release be officially out?.
-
@stevedan I depends on what kind of issues we find with it as we continue testing it. We're hopeful that it will be ready for official release in the next week.
-
@Eric-Katzfey Maybe you can help me fixed but the vio result on Qgroundcontrol is streaming at 1hz, and the reaction speed of the remote control on Qgroundcontrol is really bad. It reacts slow, is there something I am doing wrong
What is strange is that from the drone, the vio data ms is fine voxl2:~$ voxl-inspect-qvio

-
@stevedan Sorry, but could you start a new forum thread for this new issue?
-
@stevedan Can you tell if the new software release fixed the motor not spinning issue or do you need to resolve the new issue before you can test?
-
@Eric-Katzfey i would love to solve that issue first but it seems that the fact that the telemetry is low was done intentionally. I will stress test the drone on Tuesday when i go back to the office and give feedback. Although with the new code during arming the motors spins way smoother compared to before and doesn't do what happens before. I will stress test and let you know.

@Eric-Katzfey Does this version work with mavros, is there any specific detting to enable the ise of mavros?
