ABSTRACT:
An apparatus that controls movement of an arm through a gaseous or liquid fluid. The apparatus incorporates a plurality of longitudinally extensible hose members that expand and contract their respective lengths responsive to introduction and withdrawal, respectively, of hydraulic fluid thereinto and therefrom. The hose members are interconnected to one another through a plurality of longitudinally spaced, transversely disposed brace members that may serve as lever means so that expansion or contraction of one hose member can effect an opposite response in an opposed member. The brace members may be interconnected by a spine means that coincides with the longitudinal axis of symmetry of the apparatus. A sheath covers the apparatus. The arm has applications in the field of robotics and a special rat tail-like form of the apparatus provides a low drag substitute for conventional aircraft rudder and elevator assemblies.
