Just wanted to share with everyone my experience on my first dive. Unfortunately, my first dive was terrible. I deployed my blue rov from shore. Precheck dive - everything looked and operated ok, when the rov was on the surface the motors responded to controls, I was able to stream video from the rov to the laptop. I was using an F130 controller.
I set my rov in the water where it sat on the bottom awaiting for my commands. The second I armed the ROV. It went nuts!! From the documentation it’s because it was trying to stabilize at the current depth. The motors continuously run and they don’t stop unless you disarm them :-/. The show stopper was when the back vertical thruster sucked up rocks that got stuck in the thruster. After that point, the motor has failed to operate correctly, as it constantly clicks and twitches but does not spend.
Secondly, I would recommend some sort of mesh cage around the thrusters because strings of algae gets tangled in some of the motors.
The thrusters are no doubt very powerful, but I question the default code to run the thrusters when armed, I would prefer that when armed, the motors are at rest waiting to receive commands.
