Issue with stabilize mode


(Basil Alias) #1

We are using a 5 thruster configuration, with 4 vectored thrusters and 1 up-down thrusters. We are having problems with stabilize mode. The up-down thruster is working and is trying to come up/surface in stabilize mode.

Depth hold mode is working good.

Some more questions

  1. Will the six thruster configuration of bluerov work for this above frame configuration?

Issue is fixed, had to change Pixhawk orientation

Hi Basil,

Thank you for the update, please let us know if you have any other questions.

Is there any option to change ROV image from GPS tracking page?

No, the source code is available on github if you need something like that.

Thank you Patrick, we have few more queries -
We are facing problems in downloading data flash logs (.bin) over tether. The download rate is very slow - 30Kbps and for larger files (40Mb) download gets terminated due to error.
Corresponding screenshot has been attached regarding this problem

This is a known issue:


As a workaround, you can see these files on the sd card of the pixhawk.

Same issues were found with stabilize mode, we did the compass calibration and accelerometer calibration …

Hi Basil,

If you are not able to get the log from the pixhawk, you can send the *.tlog files that are under Documents/QGroundControl/Telemetry.

Hello Patrick,
Now the problem is with stabilize mode.
Top thruster is still running during stabilize mode, is there any solution for this problem?

Is the vehicle in the water? Can you show a video of your problem? It is not clear at all.
