I just got an X4 from UAV Systems International. It came with arudcopter loaded on a Cube Orange+, but i switched over to PX4 and did a few test flights. The Cube Orange+ is hard mounted, but I though that was okay for the cube since 2 of the imus are mechanically isolated. My drone was a bit twitc…

Btw another potentially related issue reported on discord: Discord

@mwshafer and @AlexKlimaj … here goes my Px4 logs for your understanding. PID tuning is not complete and appreciate any recommendations. This flight as of today https://review.px4.io/plot_app?log=04d82b6e-1653-43d6-970d-bfb67544178a https://review.px4.io/plot_app?log=ce11875d-9981-49ad-ab0d-3…

Hi, I had a 13 minutes flight time after the previous test demo ( PX4 v1.13.3 ) and surprisingly the drone flew well even in position mode without any much glitch …logs below https://review.px4.io/plot_app?log=d7f76003-ff10-4d48-b5e1-53a6382f3485 My observations are as follows a) Never switch …

We have discussed this in today’s maintainers call , and few propositions were raised: Perhaps the IMU that isn’t vibration isolated (out of 3) was being used as primary IMU for EKF2. Could you all check on that? Without access to the two logs with exact same vehicle configuration, but differen…

@ junwoo0914… thank you for the feedback…mine is a Cube Orange since beginning… Px4v1.12.3 log review was placed earlier based on another flight demo back in Jan … If you require a flight demo using Px4v1.12.3, i will downgrade the px4v1.13.3 currently installed but i am not sure if it can instal…

I used plot juggler instead to get the device ids of the imu by doing the following action import data from two PX4 log files and checking the imu_device id graph. i hope this is correct. It looks the ids matched for both PX4 v1.12.3 and PX4 v1.13.3 [Screenshot PX4 v1.13.3] [Screenshot PX4v1.1…

[image] mwshafer: Have any of the developers flown with an Orange? I myself haven’t recently but I work with several clients that fly Cube Orange and/or Orange+. I’m planning on test flying it again, I just need to mount it in my test quad again. I had a look at the IMU sensors used in Pixh…

Do you see those peaks in the angular velocity FFT? [angular_vel_peaks] Those vibrations are probably generated by your drone and amplified by the rate control loop. You should: reduce the gyro filter cutoff frequency (to ~30Hz) reduce the d-gyro filter cutoff frequency (to ~15-20Hz) reduce the…

High vibration in Cube Orange+

@junwoo0914 regarding point 1) that makes sense for thw raw accel values but why would the vibe metrics look so high for the other 2 IMUs in the logs?

Have any of the developers flown with an Orange?
