Homebuilt ROVs Forum

I've been spending way too many hours since my last post here on my ROV project, so I decided to go completely low tech / high tech. I shelved the ROV idea in favour of a much simpler towing camera system, but with the high tech data stuff. First video is of a drift in my boat to test the GPS positi...

Finally got round to making my main board for inside my ROV housing, also got the basic telemetry controls up and running also, small 7" monitor fitted into a small flight case. I'm using some old CCTV kit, which allows me to easily adapt the 'up the coax' telemetry for ROV use, so my only cabl...

I was playing around in my head with the idea of attaching a trolling motor powered dredge onto my ROV for an application I have in mind. The trolling motor I have is 32lbs of thrust and I was thinking of just using a standard Y shaped venturi with the trolling motor providing the thrust for the suc...

Ah right you are, got it, appreciate the support :-) PS. Way off topic, but I see you are from Norway. I live where the x5 minsubs did their secret testing in WW2 to then go over to Norway to sink the battleship Tirpitz and Barnes Wallace tested the bouncing bomb. Other than shellfish, I hope to sen...

I know this might sound a bit daft, but my thruster layout is 4 horizontal and 1 vertical. This is a question I thought I could solve myself, but need some brains back-up. The main vertical thruster takes the ROV down, do you need a thruster to bring it back up again, do you need an 'up' thruster or...

Hi big Al, I'm also from the UK and a newbie on here to help with building my first ROV. Sounds like you've set yourself a hum dinger of a task and design, I'm sure you'll get the answers to your queries over time. Just chip away at the individual bits and info. My own design is based on the Seaeye ...

Hi, Can someone clarify for me the preferred way to power the rov? I don't know what the deciding factor would be between sending down 12VDC to the rov or is it better to have an on-board battery supply, so the power is derived locally for the thrusters, etc? I'll be housing the relays, etc., in a P...

Does anyone know how far IR leds are capable of illuminating underwater? I would like the option on my ROV, but from what I read, I don't think they will light very far away. Has anyone got any experience of using IR on ROVs and what sort of scene illumination I am likely to get? I know it's a diffi...

Hi folks, I've just introduced myself in the new intros and would like to kick off with a wee question: as a total newbie and building my first ROV, is it OK to use small bilge pumps for thrusters? Would the pumps on their own provide enough thrust or would I have to modify the pump to take a propel...

Hi folks, Just joined here as a total newbie to the world of ROVs. My interest is freediving for scallops and I would like to construct a simple, low cost ROV for surveying some potential fishing grounds, without me getting cold and wet I apologise in advance that I will be asking an awful lot of qu...
