ROV submersible (PVC)

Step 19 ROV test in pool

Finally i have managed to test the ROV.(thanks Ben, Zac and Kat ;P)
And it was awesome!!
Never expected that 6 months of work would give me such a good result.
Well here are the pics, and the video both from onboard the ROV, from the surface and from my underwater camera.
;) enjoy

buy some speed controllers, a wireless camera and a RECEIVER+Transmitter and make it RC-driven. would be fun :)

[daniel2008]

radio waves don't transmit under water :P

Why not control it using sound. Maybe even a code of dots and dash's to program it. i.e. drop 5 feet, forward 20 feet... (its all fun right)

That's not strictly true; the VLF range is used by navies to communicate with submarines running underwater, but is limited by the fact you need a big antenna and/or High Power and is not open to amateur operators. :)

well it still has a tether, all he is doing is running an extended antenna through the tether so as to minimize the number of cables that go through the tether. technically it is just as Remotely controlled as mine as it still uses a tether.

Hi, as an estimate how much did this rov cost.?

[daniel2008]

around 100-150 $

[Danny_Payne]

 this looks great! i really am interested in giving this a go, could you tell me what waterproof motors they are please?

thanks, 
Daniel

[daniel2008]

 hey
the pumps are bilge pumps and go for between 10 and 50$ online (ebay).
i used ?pantry pumps? since i couldn't get bilge pumps.
keep me posted on how it goes and i'm happy to answer any questions you may have about the build.

how long is it?

[daniel2008]

 the rov? it's about 40-50cm long

[TenSecondEpic]

can you tell me what and were you got the propellers?

[daniel2008]

 ebay

 Hi, thanks.
I have had another idea, i could get a 'tee' piece of pvc pipe and cap it off at each end, then use one of those little 3 volt hobby motors, drill a hole about the size of the shaft in one of the ends, and poke the shaft through, then fill it with epoxy.

That way it would be waterproof and i would be able to connect it to the main frame ROV! now i just need to get a few props.

BTW; what size pvc pipe did you use since i will need to get it so the motor will fit inside.
Daniel :)

[daniel2008]

 yes that would work but i heard of people using the old 35mm camera film containers and doing the same thing but encapsulating the motor in wax. Wax is cheaper and easier to handle and 'dries' super fast. 
The pvc pipe diameter is 2.5cm i believe.

[Danny_Payne]

 Hey, ill give that a go, i think i will be a bit of trial and error for me. I will be able to get the containers and motors from Technology at school.

Thanks again!

hi you said that you will teach us how to make a proppeller

btw did you use bllast system here?

[daniel2008]

 hi,
making a propeller is neither easy or cheap so it's probably best if you buy them online or at a hobby store .
The rov is neutrally buoyant. The thruster (vertical) ensure the movement up or down

[mohamed_al_gharib]

Nice, but i have a question......... how did u make it sink under water, by only it's weight or did you add a motor that takes in water and makes rov heavier?

[BOOJAN]

I really like this rov, i like to build one, but i don't have where to use it....nice project daniel
