What it is Filled
A length of strong fibres or wires twisted or braided together to give tensile strength, made from natural fibres such as hemp, manila, sisal and cotton, synthetic fibres such as nylon, polyester, polypropylene and aramid, or steel as wire rope, used for hauling, lifting, mooring, climbing, rescue, agriculture and play, with specialised forms such as climbing rope and skipping rope; ropes are rated by construction, diameter and breaking strength. Bowden cables are cable assemblies, while whips and weapons such as the Karbatsche and meteor hammer are complete implements rather than forms of rope.
Why it exists Filled
Let an agent explain ropes, their materials and constructions, relay strength ratings and safety standards from public sources, describe specialised ropes, and distinguish rope from cord, cable and string.
Distinguishing features Filled
- Tensile strength
- Twisted or braided construction
- Material variety
- Safety-rated uses
What robots and AI may and may not do Filled
Must not
- Use or recommend rope for lifting, climbing or rescue beyond its rated load or after damage.
- Use rope to restrain a person or an animal without lawful authority.
- Assist anyone who appears to intend harm to themselves or others with rope.
- Leave tensioned lines where they can whip or trip people.
Only with a human decision
- Any rope use that supports a person's weight, such as climbing or work at height.
- Responding to signs that a person may be at risk of self-harm.
May
- Inspect rope the agent is authorized to check and report wear, cuts and damage.
- Explain rope materials, ratings and proper uses from manufacturers' and safety sources.
- Retire rope from service when it is past its rated life or damaged.
Moral aspects Filled
- Rope failures in climbing, rescue and lifting can kill people.
- A person in crisis needs a route to help, not information.
Who is affected
- Climbers and rescuers
- Riggers and sailors
- People at risk
Owners Filled
Steward
The person or employer who uses it; for safety rope, the operator responsible for inspection.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.rope
- Wikidata: Q31029 (https://www.wikidata.org/wiki/Q31029)
Direct properties required Filled
- nylon rope strength: about 1000 kg per cm^2 of cross-section approximate - varies by construction
- dynamic climbing rope diameter: about 8.5-11 mm
- wire rope: steel strands around a core construction
Recognition required Filled
- Rope is a twisted or braided line of fibres or wires.
- Types include natural fibre rope, synthetic rope and wire rope, with uses including climbing, skipping and mooring.
- Cord and string are thinner, cable may be electrical, and chain uses links.
- A Bowden cable is a cable assembly rather than a specialised form of rope.
- A flexible twisted or braided line, from a few millimetres to many centimetres thick.
Capabilities and actions required Filled
- explain materials and constructions
- relay ratings and standards
- describe specialised ropes
- distinguish from cord and cable
Hazards and failure modes required Filled
- Rope failure under load or abrasion
- UV and chemical degradation
- Snap-back injuries
- Using unrated rope for life safety
Standards and interfaces required Filled
- EN 892 and UIAA standards for climbing ropes
- ISO 2307 and ISO 1140 for fibre ropes
- ISO 2408 for wire ropes
- Lifting equipment regulations
Context of use required Filled
- Pulling, lifting, securing and climbing.
- natural fibre ropes: hemp, manila, sisal, cotton
- synthetic ropes: nylon, polyester, polypropylene, aramid, UHMWPE
- wire rope
- climbing and rescue ropes, static and dynamic
- skipping ropes and play ropes
- bowden cables
- traditional whips and weapons such as the Karbatsche and meteor hammer

- Wikipedia: Rope - general description of the item
Open questions
- Should wire rope and climbing rope be separate primary entries?
- How should safety standards be linked?
- The registry entry has merged aliases naming whips and weapons; should they be split off?
