This is my third ROV project posted on BR forums in the past 6 years. My first two used the BR WTE and T100 motors and ESC’s, as well as other miscellaneous parts. Rusty gave me a great deal of help back then. They served me well in saltwater depths to 130 feet. You can view my videos on my YouTube …

Hi @model14 , Thanks for sharing your project progress, and some of the context behind and around it :slight_smile: [image] Richard: Hopefully, total project cost will be less than $500. I imagine that will be quite challenging to hit if including 3+ thrusters, a tether, and a video screen, …

Making progress. Photos show final setup on the endcap and strongback. Thruster shrouds are being built. You can see the thruster detail which includes modified SeaFlow bilge pumps, shaft adapter and 3" propeller. The SeaFlow pumps are very rugged, have been around a long time, and are made in the U…

All 4 propeller shrouds in place. Seems like overkill. [DSCF4750]

Nice work! [image] Richard: All 4 propeller shrouds in place. Seems like overkill. Perhaps worth noting that the prop shrouds on thruster like the T200 and T500 are there to protect the thruster but also have been intentionally designed for hydrodynamic flow. The aim is to maximise the water…

With a $500 limit I cannot concern myself too much with prop shroud design for efficiency, only for protecting the tether. What I used is off-the-shelf Lowes for $3 a piece.

I see you are using a fairly primitive control interface. Have you heard of Direct Servo Control? It was a 2-wire serial connection between an RC transmitter and receiver to test servos without transmitting RF, for testing at a field while other members are flying on older, limited-channel radios. …

I don’t agree that the control interface is primitive. What it is, is a simple straight forward method of control that I fully understand and can troubleshoot and fix if something goes wrong. The Arduino processor in the WTE does an analog read through the tether on the voltage from each potentiomet…

First test outside the bathtub test today. Couldn’t be more pleased with the results. Tether needs some more buoyancy. I didn’t achieve the $500 goal, so $600 will have to do. The WTE was only $70, and that includes the $40 BR dome. If you are interested in any details or parts breakdown, let me kno…

Portable battery charger. The nice thing about freshwater use is being able to charge on site through a end cap connector. No need to disassemble anything. Just plug it in. [DSCF4759]
