[PSUBS-MAILIST] wireless control

[Alan via Personal_Submersibles]

Hank,
no you don't have to have an electrical degree from MIT but it will
help if you know someone who does.
If your control box has joy sticks on it with potentiometers that send out
0-5Volts, you could chop off the signal wires or maybe just solder in wires to this
device.....
http://www.astroflight.com/rcpwm2v
It takes the signal from a  radio control receiver & outputs it as a 0-5V signal.
So you need a radio control transmitter & receiver with at least 4 channels &
one of those units for each motor; providing the  voltage is compatible.
The radio control transmitters are a bit difficult to set up if you are not familiar
with all the RC terms & would probably be better left to some nerdy kid!
   Another way that it could be done is to fit similar valued potentiometers as you 
have on your joy stick, on to the signal wire. Then buy a servo ( thing that operates
the aileron on a RC plane) & attach that on to the spindle of the potentiometer.
The servo is plugged in to a channel on the RC receiver ( RC receiver needs 5 Volts),
now when you operate the joy stick on your RC transmitter instead of moving
the aileron up & down it turns the potentiometer one way or the other, controlling
forward & back & speed. 
You could have a switch incorporated to change from radio control to manual.
I am not sure how the radio signals would work inside a metal hull, maybe buy
a RC to & try it out first! ( good excuse)
A lot of modern motor controllers have a RC signal port. Jon was looking at a motor
controller that had that facility, not sure if he bought it.
Other than that, there is a lot happening in the robotics World with radio controlled 
battle bots etc; they are controlling a number of motors off RC. There may be
videos or advice on how to do it on their forums; however a lot of their controllers
aren't capable of the voltage & amperage we use.
Cheers Alan
