An amphibious bionic robot

Abstract

The invention discloses an amphibious bionic robot, comprising a plurality of undulating fins and a plurality of swing modules sequentially connected to form a bar-shaped body, two adjacent swing modules are connected by a universal connection mechanism, each swing module includes a base plate, The oscillating member installed on the base plate and the oscillating assembly used to drive the oscillating member to swing back and forth, the amphibious bionic robot also includes a swing driving device for driving each oscillating assembly and a steering drive device for driving the bar-shaped body to bend and turn, A plurality of undulating fins are arranged at intervals around the bar-shaped body, and each undulating fin is connected with the swinging piece of each swinging module. The amphibious bionic robot has the advantages of good environmental adaptability, high motion stability, and good amphibious motion performance.

Description

technical field [0001] The invention relates to the technical field of amphibious robots, in particular to an amphibious bionic robot. Background technique [0002] With the gradual development of marine resources and the needs of surrounding military strategies, amphibious robots that can adapt to complex operating environments and mission requirements are needed to perform various combat missions and detection tasks in the near sea that cannot be completed by humans. The amphibious robot that can adapt to the changeable terrain of the near tidal flat and the complex underwater environment has important practical value and practical significance. [0003] Existing amphibious robots are designed with a variety of structural types based on bionics, such as imitation cockroaches, imitation lobsters, imitation crabs, imitation snakes, imitation octopuses and so on. When the cockroach-like structure robot realizes the movement in the water and land environment, the drive mechan...

AI Technical Summary

Problems solved by technology

Cockroach-like structure robots need to replace the driving mechanism when moving in water and land environments, which reduces the practicability of the robot; lobster-like or crab-like structure robots can adapt to both water and land environments, but their structures are more complicated, and the efficiency of underwater movement and ground walking is relatively low. Low, affected by the design structure, its stability and walking speed are very unsatisfactory; the snake-like robot has a certain movement ability on land and underwater by bending the body joints, but its more complex joint structure makes it difficult to move during movement. The required energy consumption is high; the octopus-like robot uses the structural characteristics of the flexible body and can adapt to a variety of complex environments, but its walking efficiency on land is low

The American Pliant company has developed a Velox amphibious robot, which has good adaptability to land and water environments and stealth characteristics, and can be carried by a single soldier, but it still has problems such as difficult steering and poor maneuverability.

[0004] To sum up, the currently used amphibious robots generally have poor maneuverability, difficult steering, poor structural flexibility, and low walking speed on land and water, which have certain defects in adapting to the movement and travel of complex amphibious environments.
