Description

Amphibious bionic machine waterfowl
Technical Field
The invention relates to a bionic waterfowl, in particular to an amphibious bionic waterfowl.
Background
The bionics is born in the 60 th century of the 20 th century, is a leading edge discipline combining bioscience and engineering technology, and has been developed for decades, so that modern bionics has been extended to many fields, and robotics is one of the main combining and application fields. Robot bionics is an important branch in the field of robots, and is used for researching robots from a bionical angle. The research in this respect has attracted great interest and attention from related personnel and experts in various countries, and has achieved a great deal of success and positive progress.
However, there are many studies on the bionic robot adapted to only a single environment of water activities or land crawling at home and abroad, and there are few studies on the amphibious bionic robot. With the progress of human understanding, developing, utilizing and protecting ocean resources, conventional underwater robots cannot meet the working needs in an amphibious environment, and thus have great significance to the research of amphibious robots.
In recent years, the us IS robot company developed an underwater autonomous walking robot ALUV which has six legs, each leg has two degrees of freedom, has an amphibious motion function, but can only perform crawling motion, IS only suitable for underwater motion, and has a relatively short motion distance. In 2005, the university of Mejier developed an amphibious robot Whegs simulating cockroaches, and the propulsion mechanism adopts a three-spoke wheel paddle leg design, which approximates wheels and can realize high-performance and stable propulsion. On the basis, georgiades C et al develops an amphibious hexapod robot AQUA, the AQUA adopts arc legs to push when moving on land, and the characteristics of high maneuvering performance and good universality of the arc legs are utilized to realize high-speed pushing in various land environments; under water, the AQUA can realize the motions of cruising, lifting, pitching, steering, rolling and the like by utilizing the flapping propulsion of six paddles. Because of the different propulsion mechanisms employed by AQUA in land mountains and under water, manual replacement of the drive mechanism is required when making the transition. An amphibious robot snake of ACM-R5 developed by Tokyo winter night university in Japan is composed of a plurality of joints, each joint has two degrees of freedom, and can realize pitching and yawing movements. During the land exercise, ACM-R5 is propelled by the body in a meandering manner, and can realize the rolling motion; during underwater exercise, ACM-R5 is propelled by eel-like fluctuation. However, ACM-R5 robots move slowly, only up to 0.4m/s.
The robots are required to have high flexibility and high environmental adaptability in the face of exploration tasks of complex space environments of water and land, such as detection in submarine pipelines, monitoring of organisms in coral reefs, exploration of minerals in submarine rock joints and the like. At present, robots at home and abroad have more researches on single environments applied to water or land, and have less researches on amphibious; the study of amphibious bionic robot using crab, tortoise, cockroach, snake and other biological templates as bionic objects is very few. The problems of slower movement, single movement mode, single adaptation environment, low environment adaptability, low flexibility and the like of various robots exist.
To sum up, the existing autonomous underwater vehicle/robot and amphibious robot have the following problems:
(1) The torpedo-shaped design and propeller propulsion are mostly adopted, the mechanical structure of the propeller propulsion device determines that the propeller propulsion device can advance and retreat to generate larger speed, but the turning radius of the propeller propulsion device is large, and the propeller propulsion device is not suitable for operation in a narrow area. In addition, the volume of the propeller is large, the noise generated by the propeller is large, the power consumption is large, and the concealment performance and the biocompatibility are reduced.
(2) The bionic principle design is generally adopted, such as bionic crabs, tortoise, cockroaches, snakes and the like, and the bionic crab robot can only crawl on land and under water, and has a relatively short movement distance. The bionic tortoise robot is inflexible in submerging and overturning movements, high in resistance and slower in movements, and can only crawl on land. The bionic cockroach robot adopts different driving structures under water and on land, and when the underwater and land movement is switched, the driving structures need to be manually replaced. The bionic snake robot adopts a joint type design, and the land and underwater movement is slower and can only reach 0.4m/s. Most robots cannot perform an efficient transfer of the submerged movement. Although the snake-shaped robot can freely submerge, the speed is low, the movement space is small, and the movement on the road is inflexible.
(3) Many of the bionic templates are used as bionic templates for land bipedal exercise, and few researches are carried out on underwater and amphibious bionic aspects.

The motion principle of the bionic machine waterfowl is as follows:
the continuous rotation of the output shaft of the third motor 3-31 of the power leg drives the crank 3-32 to rotate, the crank 3-32 pulls the slide bar 3-33 to stretch back and forth in the rectangular hollow tube at the lower end of the second motor casing 3-27 of the power leg, so that the slide bar 3-33 drives the second motor casing 3-27 of the power leg to swing back and forth periodically around the rotating shaft 3-47 at the outer side of the second motor casing 3-27 of the power leg, and the second motor casing 3-27 of the power leg drives the connected part to swing back and forth periodically, thereby providing power for the movement of the power leg.

The worm wheel swing rod 3-45 rotates clockwise to a certain angle to be in contact with the rotating shaft 3-47 at the outer side of the second motor casing 3-27 of the power leg and toggle the rotating shaft 3-47, so that the spring 3-39 is compressed. When the worm wheel swing rod 3-45 rotates clockwise to the upper part and is separated from contact with the rotating shaft at the outer side of the second motor casing 3-27 of the power leg, the spring 3-39 releases elasticity to push the rotating shaft at the outer side of the second motor casing 3-27 of the power leg to move downwards so as to drive the whole power leg to move downwards, and the elasticity enables the bionic waterfowl to generate jumping motion. (because the length of the worm wheel swing link 3-45 is fixed, when the distance limit of pushing is reached, the worm wheel swing link 3-45 suddenly loses contact with the rotating shaft 3-47, the rotating shaft 3-47 and the whole of the connection are subject to downward elasticity of the spring 3-39, and the force is exerted on the ground to generate jump)
