Our BlueROV2 is currently running under BlueOS 1.0.1 and ArduSub 4.1.0 and we are using a logitech F-310 joystick. We made some tests yesterday to see if everything worked fine but we faced some issues.
First, the ROV is under the surface, we use depth hold mode, when we want to move forward the vehicle, it is going forward and UP as you can see in the following video (ROV test depth hold - YouTube). Sometimes our vehicle was completely upside down at the surface, the only button used is the one to go forward.
Second, the ROV is at the surface, we use the stabilize mode, when we use the button to go forward our vehicle is going towards this direction but it is making undulations like a porpoise as you can see in the video (ROV test stabilize mode - YouTube). Again, we are only using the forward button of the joystick.
Third, in stabilize mode our vehicle has a constant roll on the left. The left engine seems to always push water up which make the left side of the ROV going down.
We are assuming all these problems come from one cause, but we don’t know what it is.
Has anyone faced the same problem and knows how to fix it?
Thanks for your help!
