Rope Rule question
Before I ask on the Q&A, what are your thoughts on:
Rope - Loop I04 When “measured end to end” for a looped rope, is that “as looped”, or before looping? Can I have a 10 ft rope, when looped, is only 7 feet long? Rope - DAVITS I04 Is there a limit on how much of the rope can be above the DAVITS point? For purposes of min/max length, should it be measured from the DAVITS point, and not the “end “? If I wanted 2 feet to hang below the DAVITS point, I could put 3 feet of the Rope above the DAVITS Interface. |

Re: Rope Rule question
i think it is as-looped. if you change the looping, it needs reinspection, so it must be inspected in final form.
It is true there does not appear to be a spec for the length between the davit end and the davit knot. I expect this to be clarified. |

Re: Rope Rule question
Pretty sure the intent of the length limit is for while its hanging from davit. They don't want you having a rope that interferes with an opponents ability to leave their retrieval zone.

Re: Rope Rule question
I haven't done the math, but there is a minimum length to get the ROPE to attach to the AIRSHIP.

Re: Rope Rule question
I think the minimum length is such that hanging from the davit, it should just reach the top of a tall robot. the maximum length is such that it might just brush the floor.

The ROPE must be able to reach the hook and loop strap on the AIRSHIP. I don't know what this length is (Davit --> Launch Pad --> Hook&Loop Strap). |

Re: Rope Rule question
From page 20, it looks like the DAVIT is 6'7" from the floor. There is a minor horizontal portion of the DAVIT.
Per I04, page 100, the rope length is 5'3" to 8'0". which means it can be about 1'4" (16 inches) off the floor to 1'5" dragging on the floor. So, any robot should be able to reach the rope. |

Re: Rope Rule question
They're not going to require teams to undo all their elaborate rope-knotting for inspection. Therefore, the length requirement must be with knots.

Re: Rope Rule question
I don't think so. The touchpad is 4'10" from the floor, but the DAVIT is higher than that (the rope runs down through the middle of the touchpad assembly). I think the davit is 6'7" from the floor.

Re: Rope Rule question
Wow... thanks. We built one of these in our lab and I don't think we realized it was secured to the Davit. We were under the impression it was secured at 4' 10" right above the plate but now I see that isn't the case. I'll bring this up tomorrow to my team. Thanks.
