Description

Robot The present invention relates to a robot. Conventionally, robots that provide healing to users by interacting with users are known (see, for example, Patent Document 1). In addition, a robot is disclosed having an outer surface member constituting an outer surface, a heating element disposed in a space surrounded by the outer surface member, a heat transfer unit that transfers heat from the heating element to the outer surface member, and a heat transfer control unit that adjusts the amount of heat transfer between the heating element and the outer surface member by operating the heat transfer unit (see, for example, Patent Document 2). FIG. 1 is a schematic perspective view of a robot according to an embodiment. FIG. 2 is a schematic side view of a robot according to an embodiment. Figure 3 is a schematic cross-sectional view of the line III-III in Figure 2. FIG. 4 is a diagram schematically showing the configuration of a vital sensor according to an embodiment. FIG. 5 is a block diagram showing the hardware configuration of a control unit according to an embodiment. FIG. 6 is a block diagram showing the functional configuration of a control unit according to an embodiment. FIG. 7 is a schematic cross-sectional view of an example of a composite material according to an embodiment. FIG. 8 is a schematic cross-sectional view of another example of a composite material according to an embodiment. FIG. 9 is a diagram illustrating the measurement location by energy dispersive X-ray spectroscopy using an ultra-high resolution field emission scanning electron microscope in a composite material having an exterior member according to an embodiment. FIG. 10 is a drawing showing the results of observing a cross-section of a composite material in an exterior member according to Example 1 using a scanning electron microscope. FIG. 11 is a diagram showing the relationship between the restorability and deformation rate of an exterior member during unloading. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, the same reference numerals are assigned to identical components, and redundant descriptions are appropriately omitted. The embodiments described below are intended to illustrate a robot for embodying the technical concept of the present invention and do not limit the present invention to the embodiments described below. Unless otherwise specified, the dimensions, materials, shapes, relative arrangements, etc., of the constituent parts described below are intended to be illustrative and not to limit the scope of the present invention solely to them. Furthermore, the sizes or positional relationships of the components shown in the drawings may be exaggerated to clarify the explanation. In this specification, for ease of understanding, in a robot according to an embodiment, the vertically upward side when a user hugs the robot is referred to as "up," and the vertically downward side as "down." The upward and downward directions are collectively referred to as the up-down direction. The direction perpendicular to the up-down direction is referred to as the horizontal direction. Among the horizontal directions, in a robot according to an embodiment, the direction in which the user is located when the user hugs the robot is referred to as "front," and the direction opposite to the direction in which the user is located is referred to as "back." The forward and backward directions are collectively referred to as the front-back direction. Among the horizontal directions, the direction perpendicular to the front-back direction is referred to as the side direction. Among the side directions, the left side when viewed from the robot according to an embodiment is referred to as "left," and the right side when viewed from the robot according to an embodiment is referred to as "right." However, in the present specification and claims, terms indicating a specific direction or position (e.g., "up," "down," "side," "right," "left," and other terms including these) may have a relative positional relationship, and the direction when using the robot according to the embodiment is not limited to the above. In addition, in the embodiment, orthogonality may include an error of within ±10° with respect to 90°. The robot according to the present embodiment is a robot capable of communicating with a user. A user refers to a user of the robot. Representative examples of users include office workers living alone, seniors whose children have become independent, and frail elderly individuals who are recipients of home medical care. In addition, the user may include, in addition to the user of the robot, contact persons who simply interact with the robot, such as a robot manager. Communication according to the present embodiment includes exchange or communication involving only language, and exchange or communication involving contact or mutual interaction. For examp
