Controlling Depth

[PSCG]

Or, if the parts inside the ABS box allow it without problems, fill it with wax or oil (or something else that cannot being pressured).

I am also using a PWM variable speed control to adjust the vertical thruster for precise hovering ability.

I with Jim on that, I am using ones from Critical velocity 15 amp bidirectional. commercial rov vertical thrusters are always moving

Thanks for the ideas!

which speed controler is easy to get im using the bilge pump moters thanks

On a previous ROV our horziontal thrusters were controlled by relays, but I wanted a way to control my vertical position, so I add a bi-directional speed control I bought from Carls's Electronics...... http://www.electronickits.com/kit/compl ... r/k166.htm

This little kit uses a pot to control speed. I remotely connected the three wires for the pot in my drivers box on the surface. This gave me precise up and down thruster speed.

If you have a PWM signal at the ROV, then a brushed ESC (electronic speed control) is the way to go.

I like that idea.
