Abstract

Window cleaning is the most dangerous jobs when it comes to clean the skyscraper. There are many types of window cleaning technique that apply in this job. These techniques are dangerous if highly safety precaution do not take seriously and can lead to serious accident and death. Many reports regarding accidents that involving falling from skyscraper which results in serious injury and death to window cleaning workers. Until today, we are still using the same methods that are dangerous to the workers. To overcome this problem, an automated window climbing robot was designed and developed by using double acting pneumatic cylinder with suction mechanism in order to help the robot climb the window glass. When develop a window climbing robot, the major problem is gravitational force exerted toward the earth. As the solution, a window climbing robot is develop using the vacuum suction mechanism as the main holding mechanism with the helping of suction cups. The desired path for the robot which can hold and move on window glass surface. Performance of the robot in term of velocity of robot, the theoretical holding force of robot and vacuum suction pressure required are analyzed in this research. In FluidSim Software, the double acting pneumatic cylinder is simulate to find its theoretical velocity. In the experiment, the prototype is travel upward vertically follow the path. The distance travel by the prototype is taken by time to complete the path. The velocity of the prototype can be calculated. The mass of the robot is 0.466
