Vertical thruster position and buoyancy balance
Posted: Dec 28th, 2018, 3:38 pm
My overall ROV design is a PVC rectangular box.
The front has a waterproof box which houses electronics.
Behind that is a vertical thruster as well as thruster on the left and right.
Like this: The air in the electronics box makes the front very buoyant. I estimate it will take about 11 pounds of ballast to make the ROV neutrally buoyant.
I'll add the weight to the bottom.
Notice how the vertical thruster is not centered from front to back.
My brain sees this as a problem at first glance. I don't want the back end to move faster vertically than the front.
Will adding weight more to the front to give the ROV a horizontal attitude solve this?
Can anyone confirm this? Should I be worried this design?
Thanks for helping me!
