2.61b8 Yaw recenter problem
  • Gregmaan
    I have a problem with the latest beta and Yaw axis. In case of impacts or to hard movements the Yaw axis recenters always counter clockwise.
    I am using Pixhawk serial connection and 2 I2C IMUs (Second above Yaw).
    When it "recenters" it moves nearly 360 degrees counter clockwise and not only a few degrees clockwise.
    Any Ideas?

    Hello, Grefor.

    We will add this problem to the bug-list of 2.61, thank you.
    If it is possible, can you shoot a short video of this weird behaviour?

    Hi Alex,
    sorry for the delay. I found it not very helpful to send a video....
    In the meantime I found my problem:
    I am not sure if its a bug or a self made issue:
    I set up the offsets (Follow Mode/Advanced tab) automatically and enabled "Apply offset correction when axis is not following".
    Both functions gave me the problem. If I leave the offsets "0" and "..offset correction ..." disabled, all works fine.
    Maybe its worth to take a look at the auto offset function?
    Cheers

    Hi Alex,
    with some further tests .... I was on the comepletly wrong way:
    Thats was no recenter problem.
    There is a problem with Mavlink when the orientation of the copter went above magnetic south:
    When I disable mavlink all is fine.
    Problem is also that in one of 10 reboots the problem does not exist.
    For me its very hard to understand.
    Cheers Gregor

    Maybe you can give me a hint how to log the problem?
    I enabled logging in the gui but I don´t think there are the needed data in there.
    When I move the gimbal over magnetic south the yaw went to the other direction and tries a 360 degree turn.

    Cheers Gregor
