Homebuilt ROVs Forum

i'm in discussion with www.upag.eu now regarding 100/94mm extruded acrylic tube, and some other tubes for an www.openrov.com build. i need to buy 2meters of it, but they only charge 2euros for each cut. so if you are interested we can do a group buy and split cost. they gave me an offer on 40euros t...

national geographic has done this already. they talk about it in this video: http://www.youtube.com/watch?v=VrcWD2Ok ... r_embedded
there are probably more information about this system other places aswell.
they use glass spheres, and use just glass-vs-glass as sealing as i understood.

Norwegian suppliers of plastic materials that you can talk to:

Ya that would work. I was just thinking. If the pressure inside is higher the oil goes out instead if water in. Leaks happen. I was just thinking out loud. in commercial systems like this you pressurize the oil, and dont have any air in the system. and you have either a piston or an flexible hose t...

you could use a oscilloscope to compare those signals, that would show it quite easily.

is it this one? http://www.spektrumrc.com/Products/Defa ... =SPMAR6210
that could work yes.
simplest test is to connect in you tether in between and see what happens.

how are going to send the signals between the dx6i and the rov? I figure I'll link the transmitter antenna to the tether and have that particular wire terminate outside the hull so it only has to transmit through about 6" of water. That should work shouldn't it? i doubt it will. it could work ...

No problem! i've turned my focus a bit away from this way of controlling my rov project, and have taken an intresst in the openrov system. but i'm very interessted in knowing if you get the circuit to work! please post an update here. and to everyone thats interessted in the gerbers to my board - dr...

Really cool stuff!
where did you get the planetary gears for the motors?
