If they have code inside that can do that, and you bought their product, you have the right to get the source code. It would be nice if you contributed it back to us in the form of a github pull request.
I do not think they did anything that fancy, but it would be good if they did 
It would be fun to add it though. link 
I for some reason here a script callingā¦ I will let those with padded rooms test it thoughā¦
I will certainly try and get that from them to have a closer look.
thanks for the explanation. So, according to the tlog, 2 of the motors failed at the same time, right?
When I plotted the tlog using https://plot.ardupilot.org/ I could tell the drone Rolled clockwise and the information about the motors confirms it.
Is there anything that could help indicate or rule out any sort of collision (with a bird, for instance), prior to the abnormal behaviour of the drone?
obs: I checked some vibration parameters but I am not sure they would capture this aspect - what do you guys think?
Is there anywhere I could get this information in the documentation? I tried to find it, but maybe I didnāt use the right keywords.
I doubt they did it, either.
Who claimed that it could fly with 3 motors was one of the course instructors and unfortunately I donāt have it written down or documented. After hearing that I felt much more confident to fly the drone with our expensive camera.
that is impressive!
now that I try and picture our (RIP) drone doing it, I see a couple of issues: just to begin with, the propellers were huge and dead sharp. And as the drone was not too small either, I guess someone couldāve gone badly hurt. The size was very similar to their v2: link.
Vibration in Z seems to increase and start to drop before the others (X and Y).
Does/Could it indicate anything in particular?
The Roll seems to happen before the peak in the servo outputs. Does it mean the behaviour of the motors happened in an attempt to correct the Roll?
Is there any indication that the roll could have been caused by a problem affecting one side of the drone (two motors at the same time)?
Is there any clear indication that the motors had an electrical failure or does it only look like a physical/mechanical problem?
Any thoughts?
Hello , did you find the cause of your problem? IOMCU reset ?
I had this on one of my machines (helicopter) it disappeared but now itās back on a new machine, but this time every takeoff for this specific machine , I take my time to understand the real reason for this problem, I changed the autopilot (pixhawk 4 ), the servos, ESC ,bec ā¦ it change nothing , I donāt believe that a drop of 0.1v causes this !!, so why not the FMU CPU restarts too !
i can be wrong but for my case I believe that there is a kind of hardware weakness ,lack of insulation ,ground loop , between autopilot and actuators can cause this .
Unfortunately, we didnāt find the drone and all we could get were some hypotheses and speculations from the analysis of the telemetry logs.
