Design and Analysis of Robotic Device for Cleaning Window Glass Panel in High Rise Building

This project is implemented to design the possible window cleaning robot for high-rise building. The study only focuses on designing a conceptual design where three main tasks being carried out. The first is to generate several design concepts based from engineering specification generated using QFD diagram which then elaborated using morphological chart. The best concept is then chosen by Pugh Evaluation Chart. The second step involves an engineering analysis on the selected design concept such as the static frictional force, suction cup force, and motor torque required. The final step is to come out with final design using AutoCAD. Based from this, the final design of the robot is designed weighted approximately of 5kg and dimension of 500 x 500 x 200 mm3. The window cleaning robot uses two motors and 4 suction cups where one of the motor acts to drive the robot vertically (upward/downward) and the other one horizontally while the suction cups are used to grip onto the windowpane. This thesis includes background and objectives of this research, design concepts, engineering analysis, the final design, discussion and a conclusion.
