Homebuilt ROVs Forum

Thanks for the great info! I am thinking about running with on-board batteries, do you think I could have the pot in my control box and my speed controllers on-board the ROV? Is there an issue with having the pot 50-75 feet from the speed controller? I was planning on using cat 6 cable to send the ...

Chas, can you explain how you thrusters are controlled by speed controls and potentiometers please? They are 15 amp pwm speed controls, they have a imput voltage from 10 to 26 volts. The pot ( nob )is wired to the speed control with 10 inch wire length, this depends on your control box, I use a Pel...

I have noticed that the majority of ROVs use extremelly thin tethers, usually made with Cat5 cable or telephone cable. I have been told that for an ROV to function, the tether needs to be thick to keep resistance to a minimum otherwise you can't get enough power. To create a ROV with a small tether...

I with Jim on that, I am using ones from Critical velocity 15 amp bidirectional. commercial rov vertical thrusters are always moving

I am going to use them on my rov tether, since my tether is .320. I have used the floats for years as I have fished up here in northen Mi. I have had nets over 300' for chubs. The key is to figure the weight of your cable, so as to get the right amount of floats to thread on before all connections a...

I am working on my 3rd rov and trying to improve each time. my first 2 are still working great. my 3rd design is not finished yet but close. here is some detail, Pelican case, 10" color monitor, the controls for this rov will be nobs ( Pots ) setup in a flat panel. all thrusters will be control...
