Portable Autonomous Window Cleaning Robot

Abstract

The idea of having a compact and autonomous office or house window cleaning robot is quite simple and very attractive. This small window climbing robot with pneumatic suction cups should be able to move autonomously along an outside surface of high-rise building office window with a relatively large area and meantime clean and wash it. Being manually attached to the outside surface of the room window the robot will execute and accomplish the task of window cleaning automatically in a predefined pattern. The sensory system will help to navigate the robot. It is noted that window cleaning robots are commercially available but pricey (in the range of USD 5000 or more). The designed robot is lightweight, small size and cheap because it is driven only by one rotary actuator and system of properly arranged conventional belts and pulleys. It uses the suction cups to stick to the window pane and set of optical sensors to detect the window frame. The microcontroller is programmed to move the robot in a specific pattern depending on the sensory data. There are no similar reasonably priced rival products available in the market yet.
