This paper proposes the small window cleaning robot using the vacuum adsorption which has the axis of rotation at the center of robot. The P1 shows the mobility of the adsorbed robot, and then P2 is design based on the consideration of the problems of P1.
The mobility of the adsorbed robot is certainly confirmed, but there are several problems as follows to achieve the practical window cleaning robot: The stability and robustness of movement, controllability of robot, cleaning ability and commercial design.
At this moment, P2 is manufactured according to the design concept as mentioned in this paper. In near future, the P2 will be demonstrated.
Furthermore, the P2 will be revised according to the following points in order to apply it into the practical use.
Cleaning Unit: Cleaning unit should be designed by the points of (a) the kind of dirty such as oil, smoke and dust, and (b) the way of cleaning such as wiping, polishing, wet cleaning with water or medicine, and cleaning by steam.
Safety: Safety is guaranteed by preventing the robot from falling down.
