Abstract: An aircraft cleaning robot comprises a robot arm (14); a brush (34) rotatably attached to the robot arm (14) to be rotated about a brush rotation axis (R); and a controller (56) configured to control the position of the cleaning head (32), wherein the aircraft cleaning robot (10) is configured to automatically orient the brush (34) such that a cleaning face (37) of the cleaning head (32) is aligned with the surface being brushed; and the controller (56) is configured to, based on input from the robot arm (14) and/or cleaning head (32), determine a cleaning direction in which the cleaning face (37) is presently facing; and, based on the determined cleaning direction, operate the robot arm (14) along the cleaning direction to apply a brush engagement pressure in said cleaning direction.

Abstract: The present invention relates to a method and a corresponding device for determining nominal mechanical data for an electronic device by means of automatic image processing of a digital image of a specimen of said electronic device. In the method an object in said digital image, which object corresponds to said specimen, is identified and appearance data for the appearance of the identified object are determined. Then, at least some of the determined appearance data are compared with a stored set of nominal appearance data, which nominal appearance data are based on a priori knowledge of appearances of electronic devices, and at least some nominal appearance data of the set of nominal appearance data are selected. Finally, the nominal mechanical data of the electronic device is determined in accordance with the selected nominal appearance data and at least some of the determined appearance data.
