bionic manta ray

Abstract

The invention belongs to the technical field of bionic robots, and specifically relates to a bionic manta ray, aiming to solve the problems of slow speed, low efficiency, poor swimming performance and single swimming mode in the prior art of underwater bionic machines. A bionic robot manta ray comprises a head cabin, a central cabin, a pair of pectoral fins, and a tail fin cabin. The pectoral fins include a crank rocker mechanism and a bevel gear mechanism. Manta ray undulating propulsion; through the cooperation of the bevel gear mechanism and the crank rocker mechanism, the complex closed motion trajectory tracking of the end of the pectoral fin of the manta ray is realized; the present invention realizes the compound motion of the superposition of two vertical fluctuations of the pectoral fin of the biological manta ray, approximately The trajectory of the pectoral fin tip, which is important for the efficient locomotion of the manta ray, was simulated. The invention has the characteristics of stable movement, high efficiency, strong maneuverability and excellent gliding performance of the manta ray, adopts a modular design, and is easy to disassemble and maintain.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and in particular relates to a bionic robot manta ray. Background technique [0002] Manta rays are the largest of the more than 500 species of rays. Unlike conventional fishes that adopt the Body and / or Caudal Fin (BCF) propulsion mode, manta rays use the Median and / or Paired Fin (MPF) propulsion mode. This type of propulsion mode has better motion stability and low-speed maneuverability, and higher propulsion efficiency. For example, the typical manta ray is known for its smooth, efficient swim and excellent gliding ability. On the one hand, by flapping the wide and flat pectoral fins on both sides, the manta ray can achieve a cruising speed of 0.25–0.47m / s and a swimming efficiency of up to 89%. On the other hand, relying on gliding motion, the manta ray can achieve long-distance migration of up to 1500m. In addition, through the coordination and cooperation of the pectoral fins on b...
