What's the best rope?

[cpapplefamily]

Does I04 and figure 9-1 really depict that a strap is a rope. Seem to eliminate difficulty and challenge of climbing a round gym rope. I admit I need more time to read and read again. At first impression I suspected the rope rule was going to be to have rope as similar to the 3 strand twisted rope depicted in the release videos.

Interpretation would be a 1/4 rope would be ok or 1" strap. The challenge is to engage the line and then is simply becomes a cable winch.

yes, the manual shows a strap as a legal possible rope, and even shows examples of ropes with knots and loops.

I honestly think they suggested it to reduce the Q&A on the topic about whether ropes need to be round in cross section (they do not).

grabbing and climbing any dangling flexible object seems tricky. I like the way they designed this.

I'm surprised. Now with this discovery a team can make a drum winch. Original presentation made us feel we are climbing more like a human would. As you climb you pass the rope through not coil it up.

Yes grabbing the line could still be tricky

Yeah, but if I climb my own rope, I can just pull the rope and robot off the field together and don't have to fiddle with whatever system for untangling the robot without power. Teams bringing their own ropes can't be that much more annoying than the standards, can it?

I like the idea of off-field rope removal, but i think you'll have a hard time getting the rope off the davit if the robot is actively against the touchpad and the section of rope between the robot and the davit is under tension.

Design your winch so it unreels (slowly) when the match is over.

Or you could just take the rope off of the airship, then remove the rope from the robot. I feel like that would be much easier.

Thanks to FRC1339 we have a final answer on glass beads.

I still think the linked rope does not actually contain glass beads after reading the manufacturer's website, but a theoretical rope containing glass beads is not legal.

After speaking with representatives of Pigeon Mountain Industries, (manufacturer of the retro-reflective rescue rope), I believe neither the question that was asked nor the answer given really settle the issue. IMO, microscopic beads of glass contained entirely within an individual nylon fiber which is then woven into the rope sheath covering the rescue rope clearly does not render the nylon fiber any less a fiber nor inflexible. Just my two cents. Careful wording of questions in Q&A is paramount.

correct, the beads don't make the nylon less flexible or less fiber. however the beads themselves are neither flexible, nor fiber, and as such, disqualify the whole rope.

Not wanting to lawyer this anymore but one question: is the dye used to color the nylon a fiber or flexible?

Just why...
