Abstract
A fluid dynamic muscle contracts when air or hydraulic pressure is applied to it. The muscle has a long elastomeric bladder covered by a long tubular braid of flexible but inextensible fibers or filaments. When the bladder is inflated the braid is forced to expand laterally, which shortens it axially when the pressure is relieved, the muscle will relax allowing a pulling force on a tendon connected to a termination on its distal end to stretch it back to its original length. These fluid dynamic muscles can be used for bending the articulation section of a borescope or endoscope.
