TL;DR
This paper presents a remote-controlled painting system for exterior walls of high-rise buildings, addressing safety and productivity concerns in manual painting. It introduces a four-direction spray mechanism actuated by servo motors, controlled via a smartphone Bluetooth interface and Arduino-based hardware, with plans to evolve into a fully autonomous robot. The methodology covers hardware components, a spinning suspension, startup, vertical motion, painting actuation, and shifting between wall sections, along with an algorithm and sensor-based feedback for movement. Experimental results from a small-area prototype show a maximum position error of 0.5 mm and an average paint-overlap of 45%, with ultrasonic sensing used to maintain wall distance; the approach demonstrates feasibility but limited by obstacles like sunroofs or arches. The work is significant for improving safety and efficiency in exterior high-rise maintenance and points to future improvements in obstruction handling and full robotic deployment.
Abstract
Exterior painting of high-rise buildings is a challenging task. In our country, as well as in other countries of the world, this task is accomplished manually, which is risky and life-threatening for the workers. Researchers and industry experts are trying to find an automatic and robotic solution for the exterior painting of high-rise building walls. In this paper, we propose a solution to this problem. We design and implement a prototype for automatically painting the building walls' exteriors. A spray mechanism was introduced in the prototype that can move in four different directions (up-down and left-right). All the movements are achieved by using microcontroller-operated servo motors. Further, these components create a scope to upgrade the proposed remote-controlled system to a robotic system in the future. In the presented system, all the operations are controlled remotely from a smartphone interface. Bluetooth technology is used for remote communications. It is expected that the suggested system will improve productivity with better workplace safety.
