Gimbal is balanced accelerometers and gyros are calibrated... without touching the gimbal you can see following regular pattern in monitoring window. What is wrong? Is it bad calibration or something wrong with IMU?
Gimbal is levelled, and then this disturbance hits in a roll angle and it will go about 20 degrees off the horizontal. Then it will slowly start to go towards horizontal again, but after about 13sec the same disturbance and gimbal will be again about 20 degrees off the horizontal and it will keep reapeating the same pattern all the time.
I have tried in both ways: calibration disabled and enabled at startup. And I tried to keep it absolutely still during calibration... Even if it wasn't perfectly still all the time - it seems to hit only Gyro_Y
And isn't it strange that acc_y is stable, but gyro_y makes this strange disturbance pattern?
I tried. Did everything from scracth. It is just gimbal. recalibrated 2 IMU's and gyros. All there is in the system is battery, IMU's and connected motors. And still this oscillation.
I also added there a video of gimbal and monitoring data. It is again this gyro_y that gets somehow disturbed after certain time period. Although it stands on solid ground and there should be absolutely no movement.
