Abstract

The invention discloses a multi-degree-of-freedom bionic jellyfish robot, which includes a base body, four mechanical arms, and biofilms; the four mechanical arms are symmetrically installed in the circumferential direction of the base body, the biofilm wraps the base body and the mechanical arms, and the interior is filled with air to Adjust the buoyancy of the mechanical jellyfish in the water; the mechanical arm consists of two sections: the upper arm and the lower arm. The upper end of the upper arm is connected to the base, and the lower end is connected to the upper end of the forearm. Rotate left and right, the big arm swings up and down, the small arm swings up and down, and the small arm rotates with multiple degrees of freedom; the robot of the present invention has a biomimetic form, many degrees of freedom, flexible operation, and strong 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...
