Problems solved by technology

The existing bionic fish technology is driven by a tail swing device with multiple joints connected in series. This method is complex to control, and the bionic fish has a large weight and large structure. The bionic fish driven by artificial muscles is costly and complicated to control. The above two technologies are not practical

Abstract

The invention discloses a surface-mounted piezoelectric drive bionic manta ray and a drive method thereof. The bionic manta ray comprises an abdomen plate, a flexible fin module and a piezoelectric transducer, wherein the abdomen plate is in a rectangular plate shape, the flexible fin module comprises a first transverse fin, a second transverse fin, a first longitudinal fin and a second longitudinal fin which are correspondingly arranged on the four sides of the abdomen plate respectively, and the piezoelectric transducer is arranged on the abdomen plate and comprises a first longitudinal piezoelectric ceramic piece, a second longitudinal piezoelectric ceramic piece and a transverse piezoelectric ceramic piece. During working, two groups of electrical signals with a pi / 2 phase difference are adopted to excite the piezoelectric transducer respectively to generate longitudinal second-order bending vibration and transverse first-order bending vibration respectively, and the longitudinal second-order bending vibration and the transverse first-order bending vibration are superposed and coupled into traveling waves to form wave-form propulsion of the flexible fins. The bionic manta ray is simple in structure, easy to miniaturize and easy and convenient to control.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a patch type piezoelectric driven bionic manta ray and a driving method thereof. Background technique [0002] In recent years, robotic bionic fish has become a research hotspot, and bionic fish can become a tool for information acquisition and patrol continuously. The existing bionic fish technology is driven by a tail swing device with multiple joints connected in series. This method is complex to control, and the bionic fish has a large weight and large structure. The bionic fish driven by artificial muscles is costly and complicated to control. The above two technologies Neither are suitable for practical use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a patch type piezoelectric driven bionic manta ray and its driving method for the defects involved in the background technology. [0004] The present invention a...
