Hi Youssef,

Are you trying to use the ROV with a joystick connected? As per [this post](https://discuss.bluerobotics.com/t/3rd-party-software-control-rc-override-vs-manual-control/5169/2) you likely need to disable joystick input in QGC or disconnect your joystick while you’re trying to use your script-based control, as otherwise the ROV is sent conflicting information from your script and QGC.

It may also be worth trying to use `MANUAL` mode (instead of `STABILISE`) to make sure ArduSub is only doing what you’ve asked it to, and only when you’re asking it to do so.
