This project details the design and development of a robotic window cleaner, encompassing a comprehensive exploration of the subject. The document begins with an introduction to the concept of robotics and its application in window cleaning, providing historical context and highlighting the evolution from manual methods to automated systems. A thorough literature review examines existing window cleaning technologies, including various design concepts such as suspended cleaners, pulley systems, magnetic attachments, and extendable wipers, alongside the evolution of robotic development, including industrial, mobile, and service robots. The methodology section outlines design criteria, required facilities, and the design process, including assembly drawings, working procedures, and engineering analyses. Detailed calculations for components such as links, the base, and motor selection are presented. The document further explores the manufacturing process, including prototype construction and electronics assembly, with considerations for environmental legislation and ergonomics. The project concludes with discussions on future work and provides a comprehensive overview of the design, analysis, and manufacturing of a robotic window cleaner.
