Robot Assisted Wall Inspection for Improved Maintenance of High-Rise Buildings

Abstract

A robotic system is designed for the express purpose of facilitating timely maintenance of the external walls of high-rise buildings, including inspection and cleaning. This paper addresses the application of a selected method of non-destructive inspection (NDI) to assess the quality of bonding of the tile-wall in such buildings. The basis for checking with the proposed method whether there are voids in the bonding and for evaluating the approximate size and spread of voids is established. The results obtained experimentally with the use of prepared specimens and on physical walls in a university campus are presented and discussed, confirming the validity of the method proposed.
