Flat Hose

[rsisk]

I see that the explanation of what we are intending to do is not clear.

We are thinking of putting a hook on the end of a flexible tube/hose that is deflated. We would inflate the hose with air from the accumulator(s) which would raise the hook to the point we could grab the bar. Then we would use a winch to lift the robot, probably deflating the tube once the hook is on the bar.

So there is no piston in the hose.

I'm still unclear whether the hose would be considered a cylinder or accumulator. It's intended use is closer to that of a cylinder.

Based on Al's last comment about the last para. of 8.3 it looks like the intent of the rules is to have a well-defined set of energy sources/actuation systems would probably exclude what we are thinking of doing, but...

...once we get specifics on the hose and fittings, I'll submit the question to the GDC for a final ruling.
