Yaw Drifting
  • RoboMotic
    Hi

    I have a 3 axes gimbal, works awsome, but when I use the none folow yaw, the yaw start to drift, very slow, but of course after a while you can notice the camera moves. I have asked the same few years ago, and I would like to know if there are solution for this. I have the las firmware, yaw enconder, Camera IMU.

    thanks

    Hello, the solution exists but not simple. YAW drifts because it does not have an absolute reference like ROLL and PITCH. Such reference may provide a magnetometer sensor. Our system supports several I2C models. But it's a very delicate device and may be confused by everything: nearby iron, magnets, high-current cables. Check our User Manual how to install and configure it.

    Another alternative is a manual drift correction. Operator can make a fine adjustment of the gyroscope's YAW bias via Adjustable variable, linked to the free RC channel. It better suits for work in studios, where operator has a visual feedback and magnetometer is not a solution because of hard environment for it.

    thanks!

    when you say a manual correction, you mean like a trim adjust?

    Does DJI gimbals and another camera provider like www.yangdaonline.com has this same drifting problems? If they dont, how they solve this problem? Thanks!

    Will be something like this?

    Mapping Of analog-type Controls
    -Parameter to adjust
    --Gyro-heading_correction
    ---Absolute or relative?
    ----Min and max??

    Hi, It seems that the yaw does not drift In Tripod Mode. But there is a new problem, the gimbal will always follow the Frame in Tripod Mode. I think if can cancel or set the Tripod Mode by ADJ, the drifting problem will be solved.?
