Claims (6)

  1. A small unmanned mobile interlocking serving robot system comprising a serving robot (100); and a small mobile robot (200) that gets on and off the serving robot, wherein The above-described serving robot comprises at least one tray (110) for loading tableware containing food, at least one movable plate (120) providing a flat surface on which a small mobile robot can ride and move on the serving robot, and a plate drive unit (130) for selectively folding or unfolding a pair of plate sections constituting the tray. The above tray is composed of a pair of plate sections (112) that are unfolded into a foldable fan structure with at least one end connected to the main body of the serving robot to form a single surface with minimal irregularities, and between the pair of plate sections there is at least one incision (111) that is continuously vertically penetrating from the outer end to the inner direction. The above small mobile robot is configured to include a mobile drive unit (210) for movement, an upper plate (220) for loading tableware containing food, and a coupling unit (230) that mechanically connects the drive unit and the upper plate. A small unmanned mobile vehicle-linked serving robot system characterized in that at least a portion of the above-mentioned joint has an outer diameter shorter than the minimum width of the cut portion, so that the joint portion of the small mobile robot can board and disembark from the serving robot along the cut portion.
  2. In paragraph 1, A small unmanned mobile interlocking serving robot system characterized in that at least a portion of the above-mentioned pair of plate sections has a multi-stage structure with different thicknesses and/or heights.
  3. In paragraph 2, A small unmanned mobile-linked serving robot system characterized in that at least a portion of the last section in contact with the above-mentioned incision has a thickness and/or height that increases from the outer end to the central part.
  4. In any one of paragraphs 1 through 4, A small unmanned mobile interlocking serving robot system characterized by the above small mobile robot additionally including a coupling part up-down driving part (240) that moves the coupling part up and down.
  5. In any one of paragraphs 1 through 4, A small unmanned mobile-linked serving robot system characterized by the above serving robot additionally including a tray drive unit that moves the tray and/or movable plate up and down.
  6. In any one of paragraphs 1 through 4, A small unmanned mobile interlocking serving robot system characterized in that one or more of the above trays also serve as a movable plate

Description

Small mobile robot-linked serving robot system with fan-shaped tray Mobile robot-linked serving robot with fan-shaped tray The present invention relates to a serving robot system used to deliver tableware (or tableware containing food) or items necessary for a meal to a guest, and more specifically, to a small unmanned mobile robot-linked serving robot system comprising a small mobile robot capable of carrying food and boarding or disembarking from the serving robot. A serving robot is a type of food tech robot that utilizes autonomous driving technology to recognize objects, including people, in spaces such as restaurants, and performs the role of delivering and retrieving food or items necessary for a meal to the place (table) where the orderer is located. Serving robots of various sizes, shapes, and functions have been developed and released both domestically and internationally, and in Korea, not only small and medium-sized enterprises but also major corporations in the home appliance and telecommunications sectors have been competing to launch diverse types of serving robots and related services. For example, LG Electronics’ CLOi ServeBot recognizes space using a LiDAR sensor and a 3D camera, expands the driving range, and enables communication between robots without an AP, allowing more than 10 robots to be operated stably in the same space. Although the adoption of serving robots is rapidly increasing due to social factors such as the development of artificial intelligence and communication technologies related to serving robots, represented by autonomous driving, the spread of contactless culture triggered by COVID-19, and increased labor costs, the function of loading and unloading tableware (or tableware containing food) or items necessary for meals onto and off serving robots has not yet been implemented. However, although serving robots equipped with one or more robot arms or serving robots that operate in conjunction with separately installed robot arms have been presented through research and development reports and patent literature, it is known that they have not yet reached full-scale commercialization due to the need for high-spec robot arms to load and unload tableware of various shapes and various items required for meals onto the serving robot. Such functional limitations of serving robots are acting as one of the major factors hindering their widespread adoption, despite the popularization of contactless culture and the continuous increase in labor costs. FIG. 1 is a conceptual diagram of a small mobile robot-integrated serving robot system having a fan-shaped tray. The present invention will be described in detail as follows with reference to the attached drawings, FIG. 1, claims, etc. The present invention relates to a small unmanned mobile-linked serving robot system comprising a serving robot and a small mobile robot for boarding and disembarking from the serving robot, wherein the serving robot comprises at least one tray for loading tableware containing food, at least one movable plate providing a flat surface on which the small mobile robot can board and move on the serving robot, and a plate drive unit for selectively folding or unfolding a pair of plate parts constituting the tray, wherein the tray is composed of a pair of plate parts that unfold into a foldable fan structure with at least one end connected to the main body of the serving robot to form a single surface with minimal irregularities, and has at least one cut section that penetrates vertically from an outer end to an inner direction continuously between the pair of plate parts, and the small mobile robot comprises a mobile drive unit for movement, an upper plate for loading tableware containing food, and a coupling part mechanically connecting the drive unit and the upper plate, wherein at least a portion of the coupling part has an outer diameter shorter than the minimum width of the cut section, so that the coupling part of the small mobile robot can board and disembark from the serving robot along the cut section. It is about the system. Here, the serving robot is a serving robot with autonomous driving capabilities that is developed, manufactured, and currently on the market by numerous domestic and international manufacturers. The small mobile robot is configured to include a drive unit, a top plate, and a coupling unit as described above. The drive unit may be configured using a wheel and power generation device of a structure applied to general mobile vehicles, such as one or more wheels or crawler tracks. The top plate may be configured in various shapes, such as a flat plate, a plate, or a tray, taking into consideration the type, shape, and size of the tableware or items to be loaded. It may also have a groove of a corresponding shape when storing cups or water bottles. In addition, the present invention relates to a small unmanned mobile-linked serving robot system characterized in that at least a port
