Design and Fabrication of Automated Glass Curtain Cleaning Machine
Abstract –
Window cleaning makes the building’s architectural glass free from dust and dirt. The traditional way of cleaning office windows cannot be applied to high rise windows with huge sections of glass. Cleaning the windows from outside requires special tools in going up and it’s really unsafe. The Window cleaner proposed is an unmanned device which would be controlled by using a microcontroller. This device would be safer compared to traditional methods of window cleaning in case of high glass structures that increases risk in loss of human life. Structure of the proposed device consists of a triangular frame and uses suction cup based adhesion technique to adhere on the glass surface. The movement of the frame over the glass is done by using special rigging. The frame consists of an automated cleaner which is run by motors and pre-programmed microcontrollers. The automated cleaner moves in vertical direction within the frame using the threaded shaft.
INTRODUCTION
There exists increasing demand for the development of various service equipments to relieve human beings from hazardous jobs and inspection of high pipes and walls. Window washing and cleaning makes the building’s architectural glass free from dust and dirt. The traditional way of cleaning office windows cannot be applied to high rise windows with huge sections of glass. The reason is because windows are extremely inaccessible. Cleaning the windows from outside requires special tools in going up and it’s really unsafe. This paper is based on a climbing system aimed to clean glasses of high-rise buildings, using suction cups for adhering to the glass. The idea is to build a small window climbing robot with suction cups which is able to move autonomously along the outside surface of window with a relatively sufficient area and meantime clean and wash it. Traditionally cleaning of building/house windows is commonly done manually by cleaners or specialized personnel. Although the window cleaning is easy from inside the room it is not that easy from the outside. Cleaning of wide windows on tall and multi-story buildings is even more tedious and very dangerous procedure. It needs either hoisting machines for manual cleaning or large, heavy and very expensive automatic cleaning machines. As a result windows normally remain dirty or dusty form outside which might obstruct the room occupant’s view. Instead our cleaning machine can be attached to the outside surface of a room window. The machine will execute and accomplish the task of window cleaning automatically.

CONCLUSION AND FUTURE WORK
The automated glass curtain cleaning machine has been successfully designed and fabricated. The project work implements a simple glass cleaning machine that uses a portable rigging for the motion there by reducing the cost of climbing mechanism. This machine can work well for buildings having completely glass exterior. The machine construction is able to perform its intended function: the efficient cleaning of glass surfaces. The suction cup attachment system ensures good contact with the support surface, is simple and reliable. Comparing with the traditional suction cup robots , the suction cup in this project does not need any onboard vacuum pump and it has advantages of no noise, little volume and weight. The overall weight of the machine is around 20kg. The cleaning process takes about 5 minutes to finish a glass window pane. Uniform cleaning by using rubber brush and optimal in-line water pump deliver soap water for removing stubborn stains and controlled spray of water by using microcontroller to reduce wastage of water. Cleans at faster rate when compared to other robots . With some modifications the machine can also be used for wall painting. Moreover, a dirt detecting technique is developed which detects dirt by measuring amount of dirt on the glass. Results of experiments using the dirt detecting technique show the validity of the discussions.
