Homebuilt ROVs Forum

regarding silting...I work in murky fresh water (5' or less vis typically) so I can never get close enough. If you get close to an interesting item on the bottom you will touch bottom and silt is relatively weightless underwater so it does not take much for it to stir up. That said, if you know this...

Very nimble. I second Steve's thoughts on vertical thruster placement. Given your design, things need to be reasonably symmetric. Rectangular designs have a bit more natural resistance to unwanted movements because the mass/buoyancy is spread out. Think of an ice skater spinning...with everything cl...

Looks great!

How thick are they and how strong are they? I've long thought about buying a 3D printer but didn't want to waste the money if they could not build pressure tollerant pieces (down to at least 200').

If this is all on the ROV side, I think the bus bar is probally more complicated than not having one. Also, I cannot fathom the advantage of combining the two motors on one ESC. It cannot spin the ROV in the yaw direction. My suggestion: For each ESC, pick a motor and have dedicated wires to it. Cou...

If the ESCs have reverse, which I assume they do, I think you are creating an open circuit from one ESC from one to another if one is in "forward" and one in "reverse". If one ESC is in reverse, it is actually sending positive current down the negative wire (blue in picture). Tha...
