[PSUBS-MAILIST] Manipulator arm

[hank pronk via Personal_Submersibles]

Alan,
It is my observation in my own life of building subs and other things.  The more complicated the project, the less likely it will see the light of day.  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.

Thanks Hank,
I am not sure how detrimental it would be reducing your self to 90 degrees of rotation.
Vance might be able to answer that.

Alan,
I would say that has merit, it is real simple and low cost.

All,would
this idea for
 rotating the gripper have merit. (See
attachment.)It
is simple & can give 90 degrees + of rotation. (would
you need more?)The
piston pulls a bolt in a rod down an angled slot in a pipe,
turning the rod & gripper.Ignore
the gripper on the end, it's just for show &
doesn't have a closing mechanism.Alan

Hank,That would be great. So on a four
function would you have eight penetrations or four
penetrations? My goal is to make a good and not to expensive
(under $2000) manipulator arm for psub members.
