Review: Analysis and future prospects of adsorption techniques employed by wall-climbing

Abstract

Based on the application of wall-climbing robots in recent years, this article classifies the existing wall-climbing robots in detail from the point of view of adsorption methods, systematically introduces the development status of various adsorption methods, and analyzes the advantages and disadvantages of various adsorption methods combined with application examples. Combined with the current research hotspot, the future development focus of adsorption method is analyzed. This article systematically analyzes the problems encountered by wall-climbing robots in wall movement, and provides a summary of key technologies. The problems of modular design are summarized, and the development direction of adsorption mode and moving unit is prospected.
