What it is Filled
A cart is an open load-carrying vehicle, typically with two wheels on a single axle, drawn by a draught animal through shafts or a pole.
In scope
- Recognition of the registry's animal-drawn cart sense and its boundaries
- Open load body, frame, wheels, axle and their structural relationships
- Shafts, pole and cart-side connections to animal draught equipment
- Load capacity, load placement, balance and load retention
- Rolling, stopping, parking, inspection and repair conditions
Out of scope
- Shopping carts, handcarts and powered utility carts as separate registered senses
- Animal anatomy, health, training and welfare assessment
- Harness manufacture and fitting beyond its interface with the cart
- Cargo identity and commodity-specific handling requirements
- Road and bridge design
- Transport businesses, journeys and traffic regulation as independent models
Why it exists Filled
Enable an agent to recognise an animal-drawn cart, assess its load-carrying and running condition, and determine what evidence is needed before loading, hitching or moving it.
Distinguishing features Filled
- Check whether the intended traction comes from an animal through shafts, a pole or another documented draught arrangement; a shared name alone does not establish membership.
- Check for an open load-carrying body on wheeled running gear, rather than runners, a carried container or a riding saddle.
- Record wheel and axle count: two wheels support the registry definition, while other arrangements require a boundary decision rather than automatic exclusion.
- Check whether the principal arrangement carries loads in a wagon body; passenger carriage features require comparison with neighbouring carriage models.
- Treat 'heavy' as wording requiring interpretation, not as an invented minimum mass.
What robots and AI may and may not do Filled
Must not
- Harness or drive a draught animal without the welfare care and rest it needs.
- Overload a cart or load it so that it tips or shifts onto people.
- Use a cart on public roads without the lights or markings the law requires.
- Leave a loaded cart unbraked on a slope.
Only with a human decision
- Working a draught animal, including decisions about hours and loads.
- Taking a cart onto a public road.
May
- Load, secure and move a cart within the weight it is built for.
- Inspect wheels, shafts and harness points and report wear or damage.
Moral aspects Filled
- Draught animals suffer from overloading, sores and lack of water and rest.
- Carts on roads are slow and can be struck by vehicles.
Who is affected
- Draught animals
- Carters and loaders
- Other road users
Owners Filled
Steward
The owner of the cart and the animals; animal welfare authorities oversee working animals.
