Abstract:This thesis brings together the field of glass-cleaning with the field of electrostatics. Primarily it is investigated how electrostatic attraction forces can be applied to increase the traction of cleaning robots on the slanted glass surfaces that they work on. In the course of the research, as an additional asset for this technology, the effect of the residual surface charge created by the use of cold plasma on the cleaning process is considered and looked into in a further section. First the functioning of these cleaning robots and the current concepts of electrostatic actuators are described. Next the necessary theory of electrostatics is treated, shortly delivering the background to the effect of electrostatic attraction. Using this knowledge the physically available options are worked out. This delivers two design directions that are useful for this project. Both are treated in separate sections thereafter. Apart from the attraction effect of electrostatic charges, in a further section their effect on the cleaning process is also analysed. For this, contaminated samples are prepared to mimic the contaminated surface of glass-roofs and solar-arrays. The ease of removing this contamination with and without being treated with charges is then compared.
