Land-Air Amphibious Robots: A Survey

This paper explores the development of land-air amphibious robots that combine the advantages of ground robots and aerial robots. The land-air amphibious robot is a multi-modal robot that can move and work both on land and in the air. They have the ability to perform tasks in different environments, have a wide range of application scenarios and high research value, and have aroused the interest of scientific researchers and research institutions. Based on all the articles we investigated, this paper first summarizes the research status of land-air amphibious robots and divides land-air amphibious mobile robots into three categories: wheeled, tracked, and legged, according to different motion structures in land travel mode. The article analyzes the advantages and disadvantages of different land-air amphibious robots and discusses the technical problems and research difficulties in the research of land-air amphibious robots. In addition, the article also puts forward the vision for the future development of land-air amphibious robots and the further work that needs to be done.
