[PSUBS-MAILIST] Manipulator arm

[Alan via Personal_Submersibles]

Thanks Hank,
I have been Looking for "off the shelf" solutions, but just finding the right
nomenclature for Googling was difficult. I think I'm after a 2 passage hollow bore
rotary union that can be used in salt water.
I'll try Googling "Fancy Foo Foo valves" & "Bindle Dorpers" instead. :)

I say forget about rotating grippers and fancy foo foo valves and bindledorpers.  Build it to work and go have fun.  Obviously a rotating gripper is better but we are not operating DW's under oil platforms.  Your wrist solution is perfect!   Rotating wrists can be added at any time, as a matter of act, there is a hydraulic rotator on ebay right now for 149 bucks.  A hydraulic rotator is the part Sean described.
