Bionics-Based Research on Frog-Jumping Robots

Abstract

With the expansion of robot applications, existing crawling, wheeled, and tracked biomimetic robots are difficult to adapt to complex terrains and have obvious limitations. Jumping robots can easily leap over large obstacles, adapt to unpredictable environments, and their sudden movements help avoid dangers. In fields such as interstellar exploration, archaeological detection, and military reconnaissance, jumping robots have broad application prospects. This design expects to design a frog-jumping robot based on bionics technology. Firstly, the physiological structure and motion characteristics of frogs are analyzed. Based on the frog’s own skeletal and muscle structure, the structure and parameters of the biomimetic robot are designed. A three-dimensional model is established using SolidWorks software and imported into Adams software for motion simulation to simulate the jumping trajectory of the biomimetic frog and the forces during movement. Some parts are selected as references and imported into Ansys software for finite element analysis. The design is judged by the simulation results. Finally, the entire model is optimized and summarized.
