A method for the manufacturing of an aircraft shell with frames, the method comprising the following steps: (i) positioning a plurality of stringers in a male mandrel, the male mandrel comprising pocket allocations for receiving the stringers, and laying up on the male mandrel a skin, the male mandrel comprising projections and/or indentations for performing a plurality of reference marks onto the skin; (ii) co-curing the skin with the stringers, thus obtaining an aircraft shell; (iii) removing the aircraft shell from the male mandrel and fixing the aircraft shell to avoid movement thereof; and (iv) assembling at least one frame in the aircraft shell; wherein the assembly of at least one frame is performed according to a method for the assembly of frames in an aircraft shell comprising the following steps: (a) identifying the reference marks on the skin using a first robot with artificial vision on board; (b) establishing a local reference for the positioning of each frame based on at least one of the reference marks; (c) grabbing a frame using the first robot; (d) establishing a relative position between the first robot and the frame based on at least one reference feature of the frame; (e) positioning the frame on an inner side of the aircraft shell using the first robot; (f) drilling holes through the frame and skin; and (g) attaching the frame to the skin with fasteners; wherein steps (f) and (g) are performed by a second robot. (i) positioning a plurality of stringers in a male mandrel, the male mandrel comprising pocket allocations for receiving the stringers, and laying up on the male mandrel a skin, the male mandrel comprising projections and/or indentations for performing a plurality of reference marks onto the skin; (ii) co-curing the skin with the stringers, thus obtaining an aircraft shell; (iii) removing the aircraft shell from the male mandrel and fixing the aircraft shell to avoid movement thereof; and (iv) assembling at least one frame in the aircraft shell; wherein the assembly of at least one frame is performed according to a method for the assembly of frames in an aircraft shell comprising the following steps: (a) identifying the reference marks on the skin using a first robot with artificial vision on board; (b) establishing a local reference for the positioning of each frame based on at least one of the reference marks; (c) grabbing a frame using the first robot; (d) establishing a relative position between the first robot and the frame based on at least one reference feature of the frame; (e) positioning the frame on an inner side of the aircraft shell using the first robot; (f) drilling holes through the frame and skin; and (g) attaching the frame to the skin with fasteners; (a) identifying the reference marks on the skin using a first robot with artificial vision on board; (b) establishing a local reference for the positioning of each frame based on at least one of the reference marks; (c) grabbing a frame using the first robot; (d) establishing a relative position between the first robot and the frame based on at least one reference feature of the frame; (e) positioning the frame on an inner side of the aircraft shell using the first robot; (f) drilling holes through the frame and skin; and (g) attaching the frame to the skin with fasteners; wherein steps (f) and (g) are performed by a second robot.
