[PSUBS-MAILIST] Manipulator

[Alan James]

Hi Rick,
If you google robotic arm calculator, you come up with a few options for
calculators that you input your criteria to. You will be able to play around
 & work out the best option quickly. This is the first one I came across.

I am planning on fabricating my own manipulator for my K-350 that will be 
hydraulic and was wondering if anybody that had experience using one on a boat 
that size would be able to let me know about how much an arm would be able to 
pick fully extended and if a VBT up forward was mandatory to keep the 
trim.
I am planning on making the manipulator out of two sections, each about 2’ 
long giving me a 4’ reach fully extended which will get me out just past my 
forward MBT. 
I realize that the lifting capacity is based on a number of things like the 
rated capacity of the rams and where they are attached to the arms so if you 
know that as well that would be great. It’s freezing here on the big Island! I 
woke up to a chilling 54 degrees and had to put on a sweat shirt just to walk up 
to my shop.

Alan,
Yes I could spring load it, It does take some effort to pull the 
fingers open.  The oil has to travel through a pretty small line and all I 
have here is a pail of 5/30 and that is a bit heavy.  I don't heat my shop 
at night so it gets chilly by morning.

Hank,
can 
you mount a wedge somewhere so you can push the manipulator grippers up 
against
it 
to wedge them open? Or have a compression spring temporarily mounted across the 
grippers?
   
You could hang some plastic fish from the garage roof  to add a bit of 
realism.

Hey, she's a banker. It's all black 
or white with them. Except for the ones with mad manibubators in the shop out 
back, one supposes.

The only problem is, Gamma's manipulator has a power only to close 
gripper.  The gripper opens with outside water pressure pushing against 
it.  So I have to jump out of the sub to open the gripper each time.  
I was trying to explain this to my wife and she replied "can't you just put it 
in a pail of water"  I am still laughing inside of coarse :-)

You're right: you gotta have the right sounds.  I 
have a friend who used 
to sit in the incomplete fuselage of his 
biplane in his garage, making 
airplane-engine noises.
