INFLATABLE CARRIER STRUCTURE, ARTICULATED STRUCTURE AND ROBOTIC ARM COMPRISING SUCH A STRUCTURE

摘要

Carrier structure comprising an inflatable tubular casing (1) which contains a pressurized fluid and which has at least one adjustable geometry section (1.2) having a central axis (2), the structure comprising adjusting means (19, 18, 10) ) of the adjustable geometry section which are arranged to generate a curvature of the adjustable geometry section such that the adjustable geometry section retains a substantially constant volume and fold forming means including stress recovery means along the at least a portion of an average line of the section with adjustable geometry, characterized in that the stress recovery means comprises an inextensible flexible link (7) which extends in at least two passage elements (5.A, 6 9) spaced from each other substantially along the middle line, the flexible inextensible link having a length adapted to bring the passage elements together by creating between x at least one fold. Articulated structure and robotic arm having such a structure.
