Document Type and Number:
WIPO Patent Application WO/2023/134185
Kind Code:
A1
Abstract:
Provided is a mechanical arm based on the minimum energy structure of a dielectric elastomer. The mechanical arm comprises a plurality of rigid origami mechanisms (10), which are connected in series. Each rigid origami mechanism (10) is substantially cylindrical and comprises two support bodies (1) and a plurality of rigid origami elements (2), wherein first creases (11) are formed at joints between the rigid origami elements (2) and the support bodies (1), and an actuating assembly (3) is correspondingly provided for each first crease (11). The actuating assembly (3) comprises a minimum energy structure type dielectric elastomer actuator. The actuating assembly (3) has two connecting ends, which can approach or move away from each other after the actuating assembly (3) is bent, wherein one connecting end of the actuating assembly (3) is a movable end, and the distance between the movable end of the actuating assembly (3) and the first crease (11) corresponding thereto can change with the bending of the actuating assembly (3); and the other connecting end of the actuating assembly (3) is a fixed end, and the distance between the fixed end of the actuating assembly (3) and the first crease (11) corresponding thereto is set to be fixed. The mechanical arm has multiple degrees of freedom, good flexibility, a high response speed, a larger actuating force, and high environmental adaptability.
