[PSUBS-MAILIST] Manipulator Arm

[Alan James via Personal_Submersibles]

Thanks Vance,
it was manipulator, periscope & camera mount, all in one but lightweight.
I imagine I'll be doing a bit of diving on my own, hence the need for some sort of
periscope. Another option could be just releasing a Buoy & coming up under it.
I've also been looking at the option of a fly-out rov. I could send it up for a look around
first. Could also send it in caves to look for crayfish with a big gripper attached.
Alan

Alan, 
I'm not sure how useful a TV periscope would be, especially when considering the weight and complexity of something you don't use very much. Besides that, light weight, in my experience, means one of two things at sea: bent or broken. As for the camera boom idea, I've seen a bunch of fine film made from a small camera piggy-backed right onto a manipulator. It saves you the need for a pan and tilt unit, can be stowed out of the way, and tells no lies about what you are trying to filch off the bottom. Operating subs without surface support is inviting trouble. They are your collision avoidance. Even in poor viz, you stop a few feet underwater and release an air bubble from the MBTs for them to locate you. We did that even with the most sophisticated tracking, just for visual confirmation.

Thanks Vance.
I was thinking of having a long lightweight manipulator with camera
that doubles as a camera mount for filming & periscope for collision avoidance
on surfacing. So a rotator as an add on might make the unit too top heavy.
If I decided on the rotator I would need to beef the whole unit up.
Is the periscope a dumb idea?
Regards Alan

It is nice to have, but you can always add rotation later.
