Re: [PSUBS-MAILIST] Delurking
I'd suggest bench testing the camera to see what it's output is. It's
probably worth looking it up on google as well to find the specs for
it. Having a camera is a long way from having an ROV.
That said I've been thinking that using a single Coax (RG6 likely) as
an umbilical might work. Basically you build a CableTV Plant that is
the single Coax. All the controls and signal items can be taken from
off the shelf over the air RF and closed circuit systems. It would
require some RF Engineering to boost, attenuate, and block the various
frequencies but it shouldn't be a big deal. One could take existing RC
helicopter control and gyro stabilization system and adapt it (with
gyro stabilization you don't have to be nearly as exact in the vehicle
design). The vehicle would have to carry it's power onboard. Thruster
could just be three pressure compensated Minnkota motors (though I
hear the carbon from the brushes tends to make compensating fluid
conductive over time). The nice thing about 24Volt motors is that most
of the people building Battle Bots are using 24V motors so there is a
ton of control parts and data available.
I figure the cost with some scrounging would break down as follows:
Motors and motor controllers $1,000
RC Helicopter Control $1,500
Batteries, Pods, Charger $800
Depth,Heading,Telemetry OSD $1500
Surface and SubSea Video $1000
Wet Mate Connectors $1000
Miscellaneous Stuff $1200
The neat thing is that the since it's got the power onboard it doesn't
need much of a console on the surface (and no generator). The down
side is that integrating other components (sonar, etc) would require
adapting wireless modems. The other draw back is the lack of continuos
operation capability. The bass boat guys get 2 days out of a pair of
deep cycle batteries, this setup would probably get 4 hours (depending
on thruster and non LED light usage).
