Just remember that G15-C states you can not attach to the field using hook and loop (AKA velcro). When you add your own rope, it becomes part of the field, therefor, you could use velcro as a rope, but you can not attach to it.
Yes, but the loops can only be 10" in diameter.
I was thinking about something like this for our team. There’s no minimum diameter listed, and I think that coiling a smaller rope would be easier. (Wrapping the field rope around a pulley seemed impossible). The only question is whether you can tie a large enough knot in the end to satisfy the > 1" requirement at the top.
getting a 1" know is just a matter of a bigger more complicated knot (I suggest a monkey fist in the extreme case).
I’m not sure i would trust a robot to just a 325 lb tensile strength. a robot will be a pretty dynamic load, and the rating goes down quickly if there is any damage. Test test test!
The rule book states that you can use a loop. But it cant be rigid? it needs to be loose. So if pulled on it tightens. And it cannot be any larger than 10" in diameter.
This can be found on page 100 for specifics.

I believe the rules in G15 make an exception on the rope so a velcro rope of “loop” and a winch drum with “hooks” would be allowed.
From G15:
Items A-G exclude ROPES installed on an ALLIANCE’S AIRSHIP.
A. Grabbing
B. Grasping
C. Attaching to (including the use of hook-and-loop tape against the FIELD carpet)
D. Grappling
E. Hanging
F. Deforming
G. Becoming entangled
I believe this only applies if you use the velcro to strategically hold the rope in place by attatching it to the carpet.
The field drawing doesn’t show anything nice about the 90 degree turn the rope makes in the davit. It’s shown as a square tube butted against sheet steel bent into a channel, with some weld. I wouldn’t expect it to be sharp, but it’s not going to be nicely rounded either. And a smaller rope is much more likely to swing and scrape across the edge than a larger one.
how about velcro, as according to the Ri3d 1.0 video?
Is there anything preventing you from using a nylon strap and a drum with barb wire to suck in the rope and winch yourself up?
Amsteel blue is another really good option that I’ve worked with in the past. Very strong, and super easy to work with, and manipulate.

Offhand, I’d say the inspectors that will take one look at your drum of barb wire, facepalm, and start patiently explaining the safety rules.
There is going to be a long Q and A on this one stand by. So many different ropes and straps. I’m supersized they only gave one example and did not spec minim diameters of weights.
As an inspector, do you believe that velcro would be allowed?
Just why…
Because who needs skin on their hands?
My team asked me that too. I need to look more closely at the construction of the loop half. I think I need the hook half is likely to be a no (75% confidence) and the loop half could be a yes, but possibly only certain brands if all the backing is woven. I’m 50/50 on that until I can look at it closely or the gdc rules.
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.
Google “Monkeys Fist Knot”. You can start with an overhand knot and add larger and larger monkey’s fists around them.
I like out of the box ideas and I am not trying to be mean, but…
The scary thing about Chief Delphi is that some of these ideas become a reality.
If that thing WAS allowed on the field, the other robots would find the nearest corner and attempt to wet themselves.
