Design and kinematics simulation of a new amphibious bionic robot
The amphibious environment is a complex terrain environment that combines multiple media.Ordinary am-phibious biomimetic robots often find it difficult to complete special and complex tasks due to their simple design structure and the ability to achieve single actions.This article proposes a design scheme for a novel amphibious biomimetic robot based on the salamander biological model.At the same time,based on the motion of salamanders in water,a pitch attitude control system is designed to enable them to perform actions such as floating,diving,pitching up,and pitching down.In or-der to verify the feasibility of the design scheme,the finite element analysis of key modules was carried out using Solid-works to verify the rationality of material strength and design structure under special circumstances.At the same time,Webots kinematics simulation was used to verify the joint angles of the amphibious newt bionic robot.The final design scheme of the amphibious biomimetic robot has a reasonable layout structure,smooth movements in amphibious environ-ments,good environmental adaptability,and high fidelity,laying the foundation for the development and application of the entire machine.
