The issues of transmitting bidirectional control and video inputs to a remote device operating in 3D are significant and worthy of admiration.

After all, It's almost the same. If it makes you feel better being in company, I hav'nt figured out how to build a real submarine either Joe.
Hey Cody
We are in the wrong forum for this. Come join Yahoo robotrov. But since you brought it up. I am planing a deep water ROV with only a fiber connection to the surface. Video will be streamed from multiple cameras and recored on the surface. There are lots of SBC's and PC104 (See: www.pc104.org) boards out there that can live on the ROV along with the battery. The cards have analog and digital I/O and most come with sample VB and C programs that make them easy to interface with relays and servos and PWM speed controllers from the RC world that then inturn run the thrusters. Control is as easy as Windows RDP. I never messed with PCL but I know a lot of PC104's use it too. As for your plans, if you just want to flip replays I don't see why you need to use any controller. I build a really simple ROV that powers thrusters using relays over 70 ft of Cat-5 with just a 9-volt battery. I build a TTL circuit for doing the same thing with reversible thrusters. You can find both on my web site: www.submarineboat.com/underwater_rov.htm And the robotrov forum has lots of talented people that have robotic experience and backgrounds in all sorts of controllers. Now to stir the locals: 1ATM subs are only good if you want to kill someone, smuggle drugs, or look cool. Otherwise they are an antiquated idea, vastly inferior to the most humble of ROV's :) ROV's Rule!

Hey everyone. I've been trying to put the idea of making a Mini, when i say Mini i mean as small as possible ROV together. i plan on using a PLC control circuit to make the controls easier. BUT i am having some troubles designing the wiring circuit. i plan on using 24V output voltage from the PLC to control Relay's that will control the motors. The tether i have decided to use is has 6 conductors and a Cat5e with 4 UTP's. i was planning on using 4 (2 pos 2 neg) of the conductors to power the thrusters, and another pair for a univ. bus bar for cameras, lights ect. i was wondering if anyone had the time or had something similar to this already done, and if so could they share a wireing diagram with me? i will need 1 UTP to xmit video. so that leaves 3 pairs for control. i was planning to have 2 thrusters on the outsides to provide forward/reverse and 2 thrusters providing div! e functions. i can change up the wiring arrangment if someone has a better idea but as for the tether thats pretty much fixed. the only change i could make is going to 12 conductors instead of 6
