Abstract

The invention relates to a bionic jellyfish robot driven by a parallel mechanical arm, which relates to a bionic jellyfish robot. The invention aims to solve the problems that the existing bionic jellyfish robot has small motion range and small driving force, and is not suitable for complex ocean environments. The streamlined end cap, the sleeve, the base and the base of the present invention are connected in sequence, one end of the drive unit is connected through the motor connection plate installed on the base, the cam drive disc is set on the output shaft of the drive unit in the sleeve, and the cam drive The upper and lower end faces of the disc are respectively provided with a track groove along its outer contour line. The contour shape of the track groove is a contour curve set with concave and convex intervals. A plurality of sliding connection seats are connected to each other in a circular array through a plurality of roller shaft parts. The track groove of the cam transmission 9 can be slidably connected, one end of each mechanical arm driving rod is connected with a sliding connection seat, and the other end of each mechanical arm driving rod is movably connected with a flexible mechanical arm. The invention is used for unmanned underwater carrying.

Description

technical field [0001] The invention relates to a bionic jellyfish robot, in particular to a bionic jellyfish robot driven by parallel mechanical arms. Background technique [0002] Unmanned Underwater Vehicle (Unmanned Underwater Vehicle) has developed rapidly in recent years along with the accelerated pace of human exploration and development of the ocean. Among them, machines that use fish and other aquatic organisms as propulsion system bionic prototypes are receiving more and more attention. s concern. Compared with traditional wavy swimming fish, jellyfish have higher mobility flexibility, environmental adaptability and target concealment, and also have an efficient flow field energy utilization mechanism, which is especially suitable for deep diving in the ocean, observation of ocean currents, Bionic prototypes of underwater vehicles such as target detection and weapon delivery. [0003] As a typical prototype of jet propulsion, jellyfish is one of the oldest swimmi...
