Abstract: Methods of cleaning a surface with an assembly comprise (i) delivering cleaning fluid to a first portion of a cleaning fabric and/or a first region of the surface; (ii) engaging the first region with the first portion and moving the first portion in a predefined motion; (iii) disengaging the first portion from the first region; (iv) replacing the first portion with a second portion of the cleaning fabric; (v) engaging the first region with the second portion and moving the second portion in a predefined motion; (vi) disengaging the second portion from the first region; (vii) replacing the second portion with a third portion of the cleaning fabric; (viii) moving the assembly relative to the surface and/or moving the surface relative to the assembly; and (ix) repeating steps (i)-(viii) with respect to a second region of the surface and with the third portion and a fourth portion of the cleaning fabric.

Abstract: Robotic surface-cleaning assemblies include a base configured to be operatively coupled to a robotic arm; a supply of cleaning fabric supported relative to the base; an applicator supported relative to the base, wherein the applicator is configured to support a portion of cleaning fabric from the supply of cleaning fabric and operatively and selectively position the portion into engagement with a surface to be cleaned; and a source of cleaning fluid supported relative to the base, wherein the source of cleaning fluid is configured to operatively and selectively (i) deliver cleaning fluid directly to the portion of cleaning fabric supported by the applicator and/or (ii) deliver cleaning fluid directly to the surface to be cleaned. Methods of cleaning a surface with a robotic surface-cleaning assembly also are disclosed.

Abstract: A method and apparatus for spraying a liquid onto a surface. An apparatus comprises a nozzle and a number of disks. The nozzle is configured to generate a spray of a liquid towards a surface. The number of disks is positioned relative to the nozzle and configured to form a gap through which a portion of the spray of the liquid passes towards the surface.

Abstract: An automated finishing system comprises a lift system and a number of robots. The lift system is capable of positioning a wing in a substantially horizontal position. The number of robots is capable of applying a number of finishing compounds to at least one of an interior of the wing and an exterior of the wing, while the wing remains in the substantially horizontal position.

Abstract: To evaluate a fastener, a cam that is contoured to correspond to a relationship between a first dimension of the fastener and a second dimension of the fastener is utilized. The cam is movable between a first position and a second position and the fastener is evaluated based on whether an electrical connection is completed when contact occurs between the cam and the fastener while the cam is moved from the first position to the second position.
