önjáró

Önjáró is a Hungarian adjective meaning self-propelled or self-moving. It is formed from ön- (self) and járó (moving), and is used to describe machines, devices, or vehicles that operate with their own propulsion system, without being pulled or moved by an external source. In technical literature, önjáró distinguishes from towed or manually operated equipment; it emphasizes internal power and drive.

In military contexts, the term is commonly attached to artillery and armored vehicles, for example önjáró löveg for self-propelled artillery. In civil and industrial settings, önjáró gépek describe equipment with built-in propulsion, such as self-propelled construction machinery and vehicles. In robotics and automation, önjáró robot or similar phrases are used for mobile robots capable of moving under their own power; when full autonomous decision-making is intended, autonóm is often preferred, but önjáró can still apply to systems that operate without constant human propulsion.

Usage notes: The nuance of önjáró is primarily about propulsion rather than cognition or control. It is often used in contrast to towed, manually moved, or remotely powered devices. The term can apply to watercraft or land vehicles equipped with engines or motors, including road vehicles, ships, or machines that move themselves in industrial settings.
