CONSTANT VOLUME ARTICULATED INFLATABLE TUBE, ROBOTIC ARM AND ROBOT EQUIPPED WITH THE ROBOTIC ARM

摘要

The invention relates to an articulated inflatable tube (1) consisting of a succession of at least two sections (2, 3), two consecutive sections (2, 3) being placed in fluid communication in leaktight manner by a connection of articulation (4) deformable, characterized in that two successive sections (2, 3) are kept close together by at least two inextensible flexible strips (7) extending on said articulation joint (4), the at least two strips flexible (7) being symmetrical with respect to the center of said hinge connection (4) and biasing the two sections (2, 3) so that they engage to contain the volume of the hinge connection (4), the tube articulated inflatable device (1) further comprising, for each articulation connection (4) flanked by two sections (2, 3), pivoting means for pivoting with respect to each other of the two sections (2, 3) along a pivot axis perpendicular to the longitudinal directions of the two sections s (2, 3) and passing through the center of the hinge connection (4).
