Abstract:

Research on the perching design of micro-UAV plays an important role in improving the endurance performance of micro-UAV,enhancing the environmental adaptability of micro-UAV and improving the long-term detection and monitoring capability of micro-UAV. With the increasing requirements for the endurance performance of micro-UAV and the adaptability of complex environment,researchers all over the world begin to study the perching technology of micro-UAV,and have made remarkable achievements in the research on micro-UAV’s principle of perching,mechanism design,method of perching,etc. This article summarizes the principle of perching,mechanism of perching and method of perching of micro-UAV in the literature in recent years,and analyzes the characteristics and development trend of the mechanism of perching. At the same time, the research on morphing UAV in the field of perching is discussed,and the relationship between UAV wall climbing and grasping and UAV perching is also expounded. In addition, UAV is divided into two categories of multi-rotor and fixed-wing for the research and analysis of perching methods, including UAV perching position selection, bionic trajectory design based on time contact theory, visual perching navigation, aerodynamic analysis and dynamic modeling of UAV and corresponding perching maneuver control. Through the research and inductive analysis of UAV perching design technology, it can provide reference for subsequent researchers engaged in this field.

Key words: micro-UAV, principle of perching, mechanism of perching, method of perching, morphing UAV, grasping, wall climbing
