What was Leonardo da Vinci’s wooden vehicle designed to move without being pushed by people or animals?

Leonardo da Vinci’s wooden vehicle designed to move without being pushed by people or animals was the self-propelled cart.

Leonardo sketched the cart around 1478–1480. Its movement came from coiled springs, which stored energy and released it through a system of gears. Steering could be set before the cart moved, allowing it to follow a predetermined path rather than being driven continuously by a rider.

The machine was probably intended for theatrical or ceremonial use, such as producing a dramatic entrance at a court event. It was not an automobile in the modern sense: it had no combustion engine, no driver’s controls comparable to a car, and only a limited stored-energy range.

The surviving drawing did not fully explain every construction detail, and modern reconstructions have helped researchers test possible interpretations. The cart is often described as an early robot or automobile, but “self-propelled cart” is the more precise historical description.
