Phil,
I think it is the same deal with 1201.

Hi, Hank,
The Vancouver area phone number belongs to an ex-dentist named Jon – I believe that UVI stands for U/w Vehicles Inc. I know him from a couple of decades ago when he and his partner (Jerry Benson – since deceased) wanted to rep the ‘Sea Urchin’. To say it didn’t work out would be an understatement. They got crossways with a number of vehicle owners by listing a spec sheet and picture of a sub without the owners knowledge and/or authorization and when someone asked the price, they would then contact the owner and tell him that they had someone who wanted to buy the owners sub . . and would turn the ‘hot buyer’ over to the owner once a suitable commission had been established. I was pissed at them offering DeepWorkers, Newtsuits, etc., without our permission – Jim MacFarlane at ISE had some of his work-class ROV’s listed by them without permission and threatened to sue them. Mind you, this was all a number of years ago, so UVI may be pure as the driven snow these days – be interesting to know if the actual owner of PC1202 has hired them to flog it or ???? Vance, any imput on this?
Phil

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! :-)

Scott,
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.

Vance,
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
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.

Thanks for the info Vance. I am starting to get a idea of some direction for a psubs manipulator.

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.
