A layup system for use in forming a composite layup structure from a plurality of plies of composite material, wherein an outermost ply of composite material has a removable film adhered thereto. The system includes a robotic device and an end effector coupled to the robotic device. The end effector includes a layer of compressible material configured to compress the plurality of plies of composite material together when positioned over the composite layup structure. The end effector further includes a first suction device configured to grip the removable film adhered to the outermost ply of composite material. The robotic device is configured to translate the end effector relative to the composite layup structure such that the removable film is peeled from the outermost ply of composite material while the first suction device grips the removable film.

The system in accordance with claim 1, wherein said end effector further comprises a rigid plate coupled to said layer of compressible material. 3. The system in accordance with claim 1, wherein said layer of compressible material has an opening defined therein, and wherein said first suction device is sized for insertion within said opening such that said first suction device is positioned for gripping the removable film. 4. The system in accordance with claim 1, wherein said layer of compressible material is defined by a central portion and an outer edge portion, and wherein said first suction device is positioned at said outer edge portion of said layer of compressible material. 5. The system in accordance with claim 1 further comprising a biasing mechanism coupled to said first suction device, wherein said biasing mechanism is configured to translate said first suction device relative to said end effector. 6. The system in accordance with claim 1, wherein the plurality of plies of composite material are stacked unevenly such that the composite layup structure has a non-uniform thickness, and wherein said layer of compressible material is configured to conform to a contour of the composite layup structure when positioned over the composite layup structure. 7. The system in accordance with claim 1, wherein said robotic device is configured to translate in a first direction to initiate separation of the removable film from the outermost ply of composite material, and wherein said robotic device is configured to translate in a second direction, different from the first direction, to peel the removable film from the outermost ply of composite material. 8. The system in accordance with claim 1 further comprising a heater thermally coupled to said layer of compressible material, wherein said heater is configured to increase a temperature of said layer of compressible material. 9. The system in accordance with claim 1 further comprising: a work surface having at least one aperture defined therein, wherein the composite layup structure is positionable over said at least one aperture; anda second suction device in communication with said at least one aperture, wherein said second suction device is configured to hold the composite layup structure in position on said work surface. 10. An end effector for use in forming a composite layup structure from a plurality of plies of composite material, wherein an outermost ply of composite material has a removable film adhered thereto, said end effector comprising: a rigid plate;a layer of compressible material coupled to said rigid plate, wherein said layer of compressible material is configured to conform to a contour of the composite layup structure, and is configured to compress the plurality of plies of composite material together, when positioned over the composite layup structure; anda first suction device coupled to said rigid plate, wherein said first suction device is configured to grip the removable film adhered to the outermost ply of composite material such that the removable film is peelable from the outermost ply of composite material when the end effector translates relative to the composite layup structure while said first suction device grips the removable film;wherein said layer of compressible material has an opening defined therein, and wherein said first suction device is sized for insertion within said opening such that said first suction device is positioned for gripping the removable film. 11. The end effector in accordance with claim 10, wherein said layer of compressible material is defined by a central portion and an outer edge portion, and wherein said first suction device is positioned at said outer edge portion of said layer of compressible material. 12. The end effector in accordance with claim 10 further comprising a biasing mechanism coupled to said first suction device, wherein said biasing mechanism is configured to bias said first suction device against the removable film. 13. The end effector in accordance with claim 10 further comprising a heater thermally coupled to said layer of compressible material, wherein said heater is configured to increase a temperature of said layer of compressible material. 14. A method of forming a composite layup structure from a plurality of plies of composite material, wherein an outermost ply of composite material has a removable film adhered thereto, said method comprising: positioning an end effector over the composite layup structure, wherein the end effector includes a layer of compressible material and a first suction device;applying pressure to the composite layup structure with the end effector such that the layer of compressible material conforms to a contour of the composite layup structure, and such that the layer of compressible material compresses the plurality of plies of composite material together;gripping the removable film with the first suction device; andtranslating the end effector relative to the composite layup structure such that the removable film is peeled from the outermost ply of composite material while the first suction device grips the removable film. 15. The method in accordance with claim 14 further comprising orienting the end effector such that the first suction device grips a peripheral edge of the removable film. 16. The method in accordance with claim 14 further comprising heating the layer of compressible material to an increased temperature. 17. The method in accordance with claim 14, wherein translating the end effector comprises: translating the end effector in a first direction to initiate separation of the removable film from the outermost ply of composite material; andtranslating the end effector in a second direction, different from the first direction, to peel the removable film from the outermost ply of composite material. 18. The method in accordance with claim 14 further comprising: stacking a plurality of plies of composite material on a work surface to form the composite layup structure, wherein the work surface has at least one aperture defined therein, and wherein the plurality of plies are stacked over the at least one aperture; anddrawing a vacuum through the at least one aperture such that the composite layup structure is held on the work surface. 19.
