Automatic Skyscraper window cleaning machine Using ATmega328P Microcontroller

The aim is to replace the current skyscraper which operates semi-automatically to move up and down in the building. In the conventional method the one end of the string is connected to the machine and other end passes through the pulley, which is coupled to the DC motor. The machine moves vertically upwards and downwards. So, each time after the operation is completed the instrument is dislocated to the new position. It also has a defect, when machine reaches the highest point of the building the water pressure is reduced based on the principle of elevation. To eliminate these errors an automatic skyscraper window cleaning machine is developed which uses high pressure pump to maintain a constant flow rate through the tube and spray out of the nozzle. The two DC motors are used to create a motion in both axes. In addition to that an Altitude/Pressure sensor is added to measure the height and pressure of air. The recorded data are sent to the operator periodically through the GSM module attached in the platform. Moreover, a DC motor attached to the shaft is used to clean the facade and flat jet nozzle to spray the water. This entire operation is controlled by an Arduino UNO microcontroller. Once the dimensions of the building are fed to the microcontroller it carries the operation.
