  "description_excerpt": "The technology disclosed herein relates to a sewing system.\n\nIn the technical field related to sewing systems, a sewing machine supported by a robot arm, as disclosed in JP2019-201742A, is known. Sewn products such as clothing are manufactured through a plurality of processes. Conventionally, although dedicated equipment such as sewing machines is used in some processes, most processes are carried out manually. In order to efficiently manufacture sewn products, automation of the process of manufacturing sewn products is required.\n\nThis specification discloses a sewing system. The sewing system includes: a robot manipulator; a plurality of assemblies attached to and detached from the robot manipulator and each configured to perform predetermined work on cloth; a server stores process data indicating a relationship between a plurality of processes for manufacturing a sewn product from the cloth and the assembly used in each of the plurality of processes; and a control device configured to select an assembly to be mounted to the robot manipulator based on the process data. According to the technology disclosed in this specification, the process of manufacturing sewn products is automated.\n\nFIG. 1 is a perspective view showing a sewing apparatus according to an embodiment. FIG. 2 is a top view showing the sewing apparatus according to the embodiment. FIG. 3 is a perspective view showing a folding assembly mounted to a tip end portion of a first robot manipulator according to the embodiment. FIG.",
