Research status and future development of wall-climbing robot

Abstract

The wall-climbing robot is an advanced type emerged in the 1960s. This kind of robot can climb and move on vertical or even horizontal walls and perform various tasks, thus has received extensive attention from researchers in various fields. Wall-climbing robots have expanded from the initial ones with negative pressure adsorption to the current magnetic adsorption robots, rotary-wing adsorption robots, and the bionic wall-climbing robots that have emerged in the past decade. More and more fields and work began to use wall-climbing robots for their services. This article classifies wall-climbing robots according to their types, systematically expounds the functions and application fields of different types of wall-climbing robots, and makes a prospect for their future development.
