In the 19th century, hand carts were used by the mormons travelling across the plains of the USA.
Physically, carts have many different shapes, but the basic idea of transporting material (or maintaing a collection of materials in a portable fashion) remains.
A cart is also a two-wheeled vehicle drawn by an animal.
A related term is buggy. One kind is for transport of a sitting toddler; also known as a push-chair (at least in the UK).
See also Dune buggy.
A perambulator (pram) or stroller is a four-wheel cart for transport of a lying baby.
