Mechanisms and basic properties of window cleaning robot

In this paper, we propose a lightweight small robot for window cleaning, which is developed for practical use in life environment. The moving mechanism is made up of 2 drive wheels and a suction cup, which are jointed around a shaft. By this mechanism the robot moves to any directions along the vertical window. First, we introduce the adsorption and locomotion mechanisms of window cleaning robot. Next, we show the design of First Prototype and then report the mobility of it. Then we analyze the adsorption and locomotion mechanisms and illustrate the design of Second Prototype based on these analyses.
