selvdrevet

Selvdrevet is an adjective used in Norwegian to describe machinery, vehicles or equipment that can move using its own propulsion, powered by an internal motor, engine or other energy source, without requiring external propulsion from a person or animal.

Etymology: The term combines selv- meaning “by itself” and drevet, the past participle of drive, meaning “driven.” Thus, selvdrevet literally conveys “driven by itself.”

Usage and contexts: The phrase is common in engineering, agriculture, maritime and consumer technology contexts. Examples include selvdrevne jordbruksredskaper (self-propelled agricultural machinery), selvdrevne kjøretøy og fartøy (self-propelled vehicles and vessels), and various automation devices. In many cases, a selvdreven device still operates under human control or follows programmed instructions, while its propulsion is internal. It is often used to distinguish such equipment from towed, pedal- or manual-powered systems.

Relation to related terms: Selvdrevet focuses on propulsion rather than control. It is related but not identical to selvstyrt or autonom. Selvstyrte eller autonome systemer emphasize independent decision-making and navigation, while selvdrevet emphasizes that movement is powered internally regardless of the level of autonomy. In maritime and industrial contexts, the term helps differentiate self-propelled units from equipment that must be pushed, pulled or anchored and moved by external forces.

Limitations: The precise meaning can vary by sector and manufacturer. In some contexts, selvdrevet may imply full propulsion capability without external power, while in others it may simply indicate internal propulsion alongside external control.
