Abstract

The invention discloses a propeller and steering engine hybrid power propulsion mechanical jellyfish, and belongs to the field of underwater robots. The propeller and steering engine hybrid power propulsion mechanical jellyfish comprises a head outer casing 1, a steering engine driving mechanism, a propeller propulsion mechanism and an outer skin 13, and is characterized in that the head outer casing 1 is symmetric to the middle axis 12 of the head outer casing; the propeller propulsion mechanism is arranged at the bottom part of the head outer casing 1, and the center line of the propeller propulsion mechanism and the middle axis 12 of the head outer casing are positioned on one line; the steering engine driving mechanism uses the middle axis 12 of the head outer casing as the symmetric axis, and is arranged around the propeller propulsion mechanism; the outer skin 13 is arranged at the outer side of the steering engine driving mechanism, and is connected with the head outer casing 1.The propeller and steering engine hybrid power propulsion mechanical jellyfish has the advantages that by using the propeller and steering engine hybrid power to drive, and adjusting the mechanical arm and propeller driving type, the multiple different movement modes can be realized; the propeller and steering engine hybrid power propulsion mechanical jellyfish can be applied to the fields of study and research, seabed exploration, study of bionic jellyfish and the like.

Description

technical field [0001] The invention belongs to the field of underwater robots, and in particular relates to a mechanical jellyfish propelled by a hybrid propeller and steering gear. Background technique [0002] Bionic jellyfish can swim for a long time in complex underwater conditions. At the same time, due to the large internal space of the bionic jellyfish, it can carry a lot of sensors and detection equipment, and can be applied to many occasions such as marine biological investigation, seabed exploration and marine lifesaving. Compared with other underwater robots, robot jellyfish has stronger concealment. So it is of great significance to the development of bionic robot jellyfish. [0003] Current biomimetic research using jellyfish as a prototype mainly focuses on a single driving mode. There are reports from time to time on the study of bionic jellyfish robots driven by memory alloys, mechanical linkages, cylinders, and electromagnets. However, these bionic robo...
