Abstract

The invention discloses a multi-degree-of-freedom bionic jellyfish robot. The multi-degree-of-freedom bionic jellyfish robot comprises a basal body, four mechanical arms and a biological film; the four mechanical arms are symmetrically mounted in the peripheral direction of the basal body; the basal body and the mechanical arms are wrapped by the biological film, and air is filled inside for adjusting buoyancy suffered by mechanical jellyfishes in water; the mechanical arms comprise two sections of large arms and small arms; the upper ends of the large arms are connected with the basal body, and the lower ends are connected to the upper ends of the small arms; and degrees of freedom are arranged according to human arm joints: the large arms are rotated left and right; the large arm swing up and down; the small arms swing up and down; and the small arms are rotated by multiple degrees of freedom. The robot has a biological simulating form, and is multiple in degree of freedom, flexiblein operation and high in adaptability.

Description

technical field [0001] The invention belongs to the field of bionic robots, in particular to a multi-degree-of-freedom bionic jellyfish robot. Background technique [0002] Bionic robot is a branch of robotics, which generally refers to a robot that has the shape or structure of a creature and replaces a human or ordinary robot to complete tasks such as surveying and detection. With the continuous development of science and technology, robots, as one of the greatest inventions of human beings, are penetrating into many fields of human activities such as military affairs, entertainment, and services at an astonishing speed. , can operate like living things that humans or ordinary robots cannot reach, and there are thousands of kinds of living things, so its research space is also very broad. [0003] Since most underwater robots or submersibles use paddle propulsion, the traveling speed is fast, but most of the degrees of freedom are low, only 1 or 2 degrees of freedom, whic...
