noun
Technical term used in engineering, medicine, and design to describe the ability to move or be moved. Often refers to mechanical joints, prosthetics, or movable parts.
このロボットアームの可動性は非常に高い。
The mobility of this robot arm is very high.
義手の可動性を向上させる研究が進んでいる。
Research is progressing to improve the mobility of prosthetic hands.
機動性 emphasizes maneuverability and rapid movement, often in military or tactical contexts, while 可動性 is a broader term for the ability to move.
Compound of 可動 (movable) and 性 (-ity, -ness), forming a technical term for 'mobility'. The exact historical derivation is uncertain, but the word follows a common pattern in modern technical Japanese.
