摘要： There is provided a mechanical avatar assembly (10) for use in a confined space (14) in a structure (16). The mechanical avatar assembly (10) includes a rail assembly (56) for attachment to an access opening (230) to the confined space (14). The rail assembly (56) includes two or more rail segments (58) coupled together to form an elongated base (62) having a rail (90) and a gear rack (106) extending along a length (64) of the elongated base (62). The rail assembly (56) further includes a carriage portion (120) coupled to the rail (90), and movable relative to the rail (90), and a drive assembly (136) coupled to the carriage portion (120) and to the gear rack (106), to move the carriage portion (120) along the rail (90). The mechanical avatar assembly (10) further includes an articulating avatar arm (180) coupled to, and movable via, the carriage portion (120). The mechanical avatar assembly (10) further includes an image capturing device (210).

摘要： A system (94) for forming composite parts (80) and a method of forming composite parts. The system (94) includes a layup mandrel (200) that includes a mandrel body (210) and a plurality of regions of isotropic surface finish (236). The methods of forming the composite part include positioning a plurality of plies (82) of composite material on a layup mandrel (200), conforming the plurality of plies (82) of composite material to a layup surface shape (212) of the layup mandrel (200), and curing the plurality of plies of composite material (82). The methods of precisely performing the plurality of operations on a composite part allows detecting a corresponding imprinted feature of a plurality of imprinted features, aligning an operating assembly of an end effector relative to the corresponding imprinted feature, and performing a corresponding operation of the plurality of operations on the composite part.
A system (94) for forming a composite part (80) with an imprinted feature (88), the system (94)
comprising:
a layup mandrel (200) that includes:
(i)
a mandrel body (210) that defines a layup surface (212) that defines a layup surface finish roughness; and
(ii)
a plurality of regions (236) of isotropic surface finish spaced-apart on the layup surface (212),
wherein each region (236) of isotropic surface finish of the plurality of regions (236) of isotropic surface finish defines an isotropic surface finish roughness that is greater than the layup surface finish roughness, and further wherein a location of each region (236) of isotropic surface finish corresponds to a desired location for a fastener hole (86) within the composite part (80

摘要： A system for forming a composite stiffener includes a support surface to support a composite sheet and a sheet-locating device to locate the composite sheet such that a first sheet-portion is supported on the support surface and a second sheet-portion extends beyond the support surface. The system includes a separation device to separate the second sheet-portion from the first sheet-portion to at least partially form a composite charge. The system includes a layup tool including a longitudinal tool-axis and a layup surface configured to receive the composite charge. The layup surface includes a curvature along the longitudinal tool-axis. The system includes a compaction device to compact the composite charge on the layup surface. The system includes a tool-positioning device to position of the layup tool such that a compaction force, applied to the composite charge by the compaction device, is normal to the layup surface.

摘要： The magnetic handling systems comprise a bladder and a magnetic carriage system. The bladder is configured to be received within a stringer interior volume of a hat stringer and comprises a magnetic insert having a plurality of magnetic walls, each configured to align with a respective wall portion of the hat stringer. The magnetic carriage system comprises a carriage having a magnetic head that comprises a bracket and a plurality of magnetic sources supported by the bracket. Each magnetic source is configured to magnetically couple with a respective magnetic wall of the magnetic insert to produce an attractive magnetic force therebetween. The methods comprise disposing a bladder having a plurality of the magnetic inserts within the hat stringer, magnetically engaging a plurality of the magnetic heads with the plurality of magnetic inserts, and conforming the hat stringer by moving at least one magnetic head relative to another magnetic head.
