Homebuilt ROVs Forum

Welcome to the site. Looks like you have been doing a lot of research and planning. Yes you are correct, pressure bulkheads, sealing wires, and your thrusters are going to be your biggest challenges. Stock bilge pumps, used as a bilge pump to move your ROV can be in-efficient. A good work around is ...

Goodluck, let us know how the build goes.

At 300 meters, the water pressure will be approx 400 psi, so you would need to use a shaft seal or o-rings to seal any shafts or rods extending through the pressure bulkhead.

The method to move the arm will depend on how heavy it is, and how much clamping pressure you want.

Thanks for the link.

I wonder if you could power the jaws with a small pnuematic cylinder and a CO2 catridge on the ROV.

Nice Videos. We have been using brushless motors running directly in fresh water for 2 years with great sucess. The bearings do tend to rust with time, but they are cheap enough to replace. We spray WD-40 on the bearings and spin the motors up at the end of the dive to remove as much water from the ...

Welcome Vinicius. Building an ROV in 5 to 6 months can be done. You will find lots of good info on the forum, and on Steves website.

Keep us updated on how your build goes. .

Both methods, Sealed and flooded are commonly used. The two ROV's I have built were watertight. The third one I am building is also water tight. Each method has it's pros and con's, Depending on the size of the ROV, a sealed hull, can add a lot of bouyancy. Not sure if the inner caps can handle a lo...

Welcome. Sounds like you have a great start to your ROV. Keep us informed on your progress.

My prop nozzles were printed on a 3D printer. Good luck, and let us know what parts your a creating on your 3D printer.

With a relay setup, you either have 100% thrust, or 0% thrust. When using an ESC, you can limit the about of thrust to each motor. This is especially true for your vertical thruster, once you are on or near the bottom, you only need a small amount of thrust to maintain you position, this also helps ...
