Hi all,
I just added the A50 DVL to our BlueROV2. I’ve upgraded to BlueOS. I’ve followed this guide: https://bluerobotics.com/learn/dvl-a50-integration/. When I get to the step of “setting the ROVs starting position”, I log into BlueOS, and it puts me off the coast off Africa. I then drag across to where I am (Melbourne, Australia), press the “set vehicle position” button, it correctly displays the coordinates, but when I go to QGC it still thinks I’m off the coast of Africa? It works other than that. If I draw a path around the alleged starting point, it will navigate the course etc.
This is obviously less than ideal. Any suggestions on how to deal with it?
Thanks
Dean
Hi @Dean.C -
Sorry for the frustration! Can you confirm what version of BlueOS you’re using, and what version of ArduSub as well? You can see this in the lower left of the BlueOS interface.
I would suspect you’re not running ArduSub 4.1.2, and if you’re already on BlueOS 1.2.6 it may be beneficial to try 1.3 Beta 9.
Apologies for the tardy reply, it’s taken me this long to get back to it.
I’m running 4.1.2, and 1.2.6. I’ve just tried it now in the lab (dry) and it seems to have worked this time? I didn’t change anything, though?
Also, regarding the location/tracking, how much of this requires as internet connection? I’d prefer to do it offline if possible. Are pre-planned flights saved on the cloud or locally?
Hi @Dean.C -
1.3.1 stable is now out, and worth upgrading too!
The DVL will position hold with no internet connection, and the DVL extension in BlueOS allows you to manually input the GPS location of the ROV - the maps will not load without internet, so you won’t be able to click them to define the ROV position.
Saved autopilot missions created in QGround Control can be downloaded to your computer, and loaded from it as well. The BlueBoat Operators guide covers a bit more on using the application for mission planning, including offline maps (QGC only.)
You may find that you need to allow the system to completely finish starting up - both BlueOS and the DVL can take a few minutes after connecting the battery, and being in the water (for the DVL), before things are ready to go! It’s good practice to keep a towel or something over the ROV to keep it out of direct sunlight.
