Vance,
The Perry 1201 is for sale in Florida, I am sure you know that but the
interesting thing is the seller contact number is in the Vancouver area.

They were ALL built in house for the manned subs, as far as I know.

Ok. I have a feeling I will go through many revisions. Did Perry ever
build their own manipulators or were they always outsourced?
Thanks,

Scott,
I think it will be simpler than that, even. All done by valves in the
pneumatic version. Purely mechanical and air. Then an upgrade could be made to
hydraulics with the same system if someone wanted. I should have some
drawings for you by Bellingham. Maybe sooner if I can find my pencils.

Scott,
You may have an opportunity here. You can offer an arm in pneumatic or
hydraulic. The arm will be exactly the same, just install hyd valves
instead of air valves. Brilliant! Even the same wiring harness will work. More
brilliant! :-)

I don't, as it happens, but I could do a sketch. Meanwhile, I'll inquire
about the possibility of doing a little cloning project on the real thing.

Do you have any pictures of it?

Scott,
Looking at Schilling, etc., is instructive, but rather like watching those
shows on cable television where young couples are trying to decide whether
to buy a five hundred and eighty-five thousand dollar house or a six
hundred and twenty-nine thousand dollar house, neither of which they can afford.
What we really need (in my opinion) is something simpler. Think mobile
gripper to start with. I know of a lightweight three-function pneumatic arm
(shoulder left-right/up-down and gripper) that worked fine. It was designed
to be easy on the pocketbook and simple to use/maintain. Valves, tubing,
three pistons, some smallish diameter aluminum pipe, and a few brackets to
build. Not a bad place to start.

Scott,
here is a link to the Schilling manipulator manuals.
_www.fmctechnologies.com/en/SchillingRobotics/Technical-Manuals.aspx_
(http://www.fmctechnologies.com/en/SchillingRobotics/Technical-Manuals.aspx)
Very scary. They are the rolls royce of manipulator.
Usually near the end of these 500 page pdfs there
are various gripper drawings with measurements
that would be a good basis for gripper design.

Hytorc makes a good line of robust, self-contained continuous duty pumps,
most adjustable from 1500 to 10000 psi. The.120 volt units we used had a
universal motor so could be run on straight off the main buss. We set them up
with an accumulator pre- charged to 1000 psi and a pressure switch set
1000 to 1500 psi. This supplied pressure to a double bank (6 each) of
Parker-Hannifen solenoids controlled with their own 12 volt tap. Twelve solenoids
gave us control for two manipulators, plus rudder and dive planes (with some
variance depending on the sub). All of this was mounted internally.
Eventually, perry went to external compensated pump/solenoid boxes for the
manipulators, but by then the subs were up in the one point five to three million
dollar range. The resultant increased budget and their growing experience
with work class ROVs made that practical. All the later boats were set up
with the external package, as far as I know.
