Re: [PSUBS-MAILIST] Rigging Motor Controllers

Have a look at Phil's stuff on the foot controls for the DW2000 and Aquarius. It must have taken a fair amount of head scratching to actually design, but once in place, you just sort of aim your feet and the pedals where you want to go and the sub follows. The pivots all have potentiometers which feed the individual motor controls and in turn, the thrusters. You might be able to do something with a T-handle video game controller. And, as mentioned, some of the ROVs do, in fact, use RC control boxes, and this may well be another (relatively) simple conversion. High frequency plays hob with electronics, so it would have to be isolated or filtered or something--that stuff's all magic to me, but I'd sure like to figure out how to do it. Then we'll build two, plus spares. Maybe another thread? We got some ferocious good tinkerers on this line. They might chime in and give us a hand.

All the talk about fixed thrusters, has me wondering about a practical way of rigging for control. I looked at Stanley's Idabel also, and don't really see much in the "down the hatch" view other than the MBT valves. Looks like the motor controllers are under the lip of the top sphere.

Looks like with Minn Kota, the Saltwater outboard mount 36V 202 lb thrust motor is ideal, and at 9k weight, probably what he is using in series there.

The fact that he "air compensated" is also of interest.

However, in looking at the rheostat control for this motor, it seems to me you need differential control of the various motors = a whole bunch of separate controls??

Problem for resolution.... How to rig control of the various motors (quite possibly 5) to make maneuvering intuitive and instantaneous, combine control where appropriate but, still maintain individual variable control??
