Wall Painting Robot

Abstract

Abstract: The automation of wall painting processes has garnered significant attention due to its potential to enhance efficiency, safety, and quality in the construction industry. This project focuses on developing an Automated Wall Painting system for both interior and exterior surfaces. The system employs readily available components such as Arduino Uno, NodeMCU, L293N HBridge Motor Driver, DC Motors, and other essential elements to achieve its objectives. The system comprises two primary components: the base and the support. The support component houses essential elements such as photoelectric seansors, paint spray mechanism, spray motor, and reservoir. Meanwhile, the base component incorporates four wheels, each driven by a DC motor, an obstacle sensor, and a 12V DC lead-acid battery for power supply. Upon activation, the system initiates the stepper motor, which drives the linear motion necessary for the support's back-and-forth movement along the wall surface. Simultaneously, the spray motor activates to ensure synchronized operation with the support motion, facilitating uniform paint application. This project addresses the challenges associated with manual wall painting, including labor intensiveness, safety concerns, and repetitive tasks. By automating the painting process, it aims to streamline operations, reduce labor dependency, and improve overall efficiency in construction projects. The system's simplicity, portability, and predictable performance make it a viable solution for enhancing productivity and safety in wall painting applications.
