Two universal wheels 202 are installed on the front and rear of the chassis 200, which control the overall steering of the robot through a motor and an encoder. An auxiliary wheel 203 is installed on the front and rear of the chassis 200 to keep the robot balanced.

[0048] The server 20 can also be electrically connected to the chassis main control board. The server 20 is used to visually identify empty seats. The user selects a seat through the operating system of the operation screen. The robot follows the user to pick up the meal and puts the lunch box into the tray. Under the control of the chassis main control board, the robot follows the user to deliver the lunch box to the selected seat. After the user picks up the meal, he selects the delivery through the operation screen.

[0049] Specifically, if Figure 3As shown, the robot includes an operating screen 101 mounted on the side of the robot; a food delivery mechanism includes a support platform 102 integrated with the side of the robot; and a tray 103 mounted on the support platform 102, which is detachably connected to the support platform 102. The size and shape of the tray 103 match those of the support platform 102.

[0050] In one embodiment, the height of the robot is between 1.15m and 1.35m. Figure 4 As shown, the operation screen 101 can be set on the top of the side of the robot.

[0051] Specifically, the operating screen 101 is electrically connected to the robot's industrial control unit, which is equipped with an operating system and supports touch and voice interaction. Specifically, to address the specific needs of community nursing home services, the robot can perform autonomous following, food ordering and delivery, material transportation, and safety inspection functions. Social entertainment utilizes interactive screen content and voice interaction modules to achieve multimodal human-machine interaction.

[0052] Furthermore, in order to facilitate the interaction between the user and the operation screen 101, as shown in FIG. Figure 5 As shown, the operation screen 101 is tilted on the side of the robot, and the tilt angle is an acute angle, which is better for users in standing and sitting positions to watch and operate, ensuring the best visual effect of viewing and operating.

[0053] Preferably, the inclination angle is between 10° and 20°, for example, the inclination angle is 15°.

[0054] like Figure 5 As shown, the food delivery structure includes a support platform 102 integrally provided with the side of the robot. The support platform 102 protrudes from the side of the robot and is a planar structure extending toward the outside of the robot.

[0055] In one embodiment, Figure 6 As shown, the first sheet metal structure 1021 within the support platform 102 is rigidly connected to the second sheet metal structure 1001 within the robot's main body, maintaining a rigid connection between the robot and support platform 102 and providing high load-bearing capacity. Furthermore, the outer shell of the support platform 102 and the robot's housing are integrated into a single piece, further enhancing the robot's load-bearing capacity. Preferably, the first sheet metal structure 1021 is perpendicularly connected to the second sheet metal structure 1001.

[0056] Specifically, the support platform and the operating screen can be set on the same side or different sides of the robot, for example: the support platform and the operating screen are both set on the front of the robot, or the support platform is set on the back of the robot and the operating screen is set on the front of the robot.

[0057] Specifically, tray 103 is detachably connected to support platform 102 via connectors. To increase the contact area between tray 103 and support platform 102 and ensure secure installation, tray 103 utilizes a large-area slot structure for detachable connection with support platform 102. Tray 103 snaps into the support platform via the slots, effectively ensuring multiple connection points between tray 103 and support platform 102 and increasing stability. This tray 103 can be used to deliver meals to the elderly and transport other daily necessities.

[0058] In this application, the tray 103 and the support platform 102 are designed to be separated, so that the tray 103 can be taken out and used independently, and the tray 103 can also be connected to the support platform 102 through a locking position, which increases practicality.

[0059] The tray may be made of plastic or metal, and this application does not limit the specific material.

[0060] Of course, as another optional embodiment, the tray 103 can also be magnetically connected to the support platform 102. Specifically, the tray is made of metal, and magnetic parts are provided in the support platform.

[0061] Further, in order to facilitate taking the tray 103, as Figure 4 As shown, the edge of the tray 103 may further include a convex surface, which serves as a side surface of the tray 103 .

[0062] In one embodiment, the tray 103 may be a rectangular tray 103, one side of which is detachably connected to the robot support platform 102 via a slot structure, and the edges of the other sides of the rectangular tray 103 include convex surfaces, which serve as the side surfaces of the tray 103. It is understood that the height of the side surfaces of the tray 103 can be designed to be convenient for handling, and this application does not limit this.

[0063] like Figure 4 As shown, the sides of the tray 103 can be turned outward, making it easier for the user to remove and install the tray 103 from the support platform 102. In addition, to facilitate the placement of long items, a notch 104 is provided on one side of the tray 103. The height of the side at the notch 104 is lower than the height of the side without the notch 104.

[0064] In one embodiment, a notch 104 is provided on one side of the tray 103, allowing for placement of longer items, such as chopsticks or straws, horizontally facing the robot. For example, the notch 104 is positioned close to the robot. It is understood that the size and side height of the notch 104 can be designed based on actual needs and are not limited in this application.

[0065] Furthermore, a circular sunken platform 105 can be provided on the surface of the tray 103 for placing water cups to maintain the stability of the water cups during transportation and prevent them from moving or spilling. It is understood that the diameter of the circular sunken platform 105 can be designed according to the size of a general water cup and is not limited in this application.

[0066] Of course, as other optional embodiments, the surface of the tray 103 may also include sinks of other shapes, such as square, oval, etc.

[0067] Further, in order to facilitate taking the tray 103, as Figure 8 As shown, there is a hole 110 on the target side of the tray 103 . Preferably, the hole 110 is a rectangular structure, wherein the target side is the two side surfaces perpendicular to the robot body 100 .

[0068] Preferably, the operation screen 101 can be installed on the first side of the robot, and the support platform 102 can be integrated with the first side of the robot, where the first side is the front of the robot. The vertical height between the support platform 102 and the bottom of the robot is less than the vertical height between the operation screen 101 and the bottom of the robot. By installing the support platform 102 on the front of the robot and below the operation screen 101, it is more ergonomic and easier for users to operate.

[0069] It is understood that the support platform 102 can be set at a height in the middle area of the robot, wherein the middle area of the robot can be considered the middle area, so as to be more convenient for users in standing and sitting positions to pick up items. For example, the support platform 102 can be set at 2 / 3 of the height of the robot.

[0070] Furthermore, to facilitate storage and simultaneous delivery of multiple items, the robot may further include a first drawer 106 embedded in the second side of the robot. The drawer is designed to be closed during normal use and opened when in use, thereby reducing the space occupied by the robot.

[0071] In one embodiment, the drawer can be connected to the sheet metal structure of the robot body through a slide rail and opened and closed by pulling.

[0072] In order to facilitate the placement and retrieval of items, Figure 4 As shown, one side panel of the first drawer 106 is higher than the other, with the lower side panel positioned closer to the front of the robot. By designing the drawers with one side higher and the other lower, the side panels closer to the front of the robot are slightly lower (while the back edge is slightly higher, ensuring adequate storage space). This allows for easier access to larger items without them getting stuck on the drawer edges, and also facilitates closing and opening the drawer, making it more ergonomic.

[0073] Furthermore, if Figure 4 As shown, the robot may further include: a second drawer 107, the second drawer 107 is embedded in the third side surface of the robot, wherein the second side surface and the third side surface are opposite surfaces; a side panel height of the second drawer 107 is higher than a side panel height of the other side panel, and the side panel with a lower height is close to the front surface of the robot.

[0074] The drawers are symmetrically installed on both sides of the robot. The drawers are connected to the internal structure of the robot and can be opened and closed by pulling. They can be used for temporary storage for the elderly. They can also be combined with the tray 103 to deliver multiple items at one time, such as the elderly's clothes, toiletries, and medicines. More valuable or fragile items to be transported can also be placed in the drawers to ensure the safety of the items.

[0075] Furthermore, if Figure 3 As shown, the robot further includes a sound pickup microphone 108 , which is located between the operating screen 101 and the supporting platform 102 . The sound pickup microphone 108 can be used for voice interaction.

[0076] In one embodiment, the sound receiving microphone 108 is located directly below the robot screen. The sound receiving microphone 108 includes a plurality of circular holes arranged in a circular rotation shape. Figure 7 For example, the sound receiving microphone is a shape of multiple rows of circular holes arranged in a circular rotation, and each row of circular holes includes multiple circular holes from small to large and from large to small. This shape can effectively ensure the sound receiving effect of the robot.

[0077] Furthermore, in order to realize the automatic following of the robot and realize the abnormality detection alarm function, a lifting sensor module 109 is also designed on the top of the robot body 100 for sensing complex environments.

[0078] In one embodiment, the lifting sensor module 109 includes at least a camera, a human infrared detector, a smoke sensor, and a fire sensor. The lifting sensor module 109 is connected to the internal structure of the robot body and the industrial control electromechanical system, and performs real-time detection of the environment by integrating multiple sensors. For example, the camera performs a full-scale scan and shooting of the environment, the smoke sensor and the fire sensor detect the air quality and fire accidents, and when the elderly person falls, the human infrared detector and the camera comprehensively detect the specific situation of the elderly person.

[0079] Among them, the lifting sensor module 109 is equipped with a pitch motor and a lifting motor, which can support the lifting sensor module 109 to perform multi-angle collection of up and down lifting, pitching and left and right viewing, so as to realize the three-dimensional space of the elderly care community environment without blind spots.

[0080] For example, human infrared detectors can detect the situation of the elderly in the environment, and combined with high-definition cameras, they can analyze the elderly's current behavior and posture. Fire sensors and smoke sensors can detect abnormal conditions in the environment, such as fires and other dangerous situations. The camera will conduct secondary confirmation and send data back to the robot's main control board, so that the robot can provide rescue or alarm.

[0081] In this embodiment, if Figure 3 As shown, the robot may include a robot body 100 and a chassis 200. The robot body 100 is installed on the chassis 200 and can support the product to automatically travel and perform tasks.

[0082] In one embodiment, the chassis 200 is in the shape of a cylinder with wheels, and the robot body 100 is in the shape of a cone with a diameter gradually decreasing from bottom to top, with a smaller diameter at the top to ensure that the center of gravity of the robot body 100 is at the bottom.

[0083] Autonomous following uses the robot's multiple sensors to collect data on its movement space and the location information of the target person, collects and analyzes the data, and decides the robot's path of action. The camera tracks the target person through real-time monitoring, and the lidar and ultrasonic radar of the chassis 200 accurately maintain a safe distance from obstacles, ensuring that the robot autonomously follows the user to provide service.

[0084] Furthermore, in order to realize emergency stop control of the robot in an emergency, an emergency stop button (not shown in the figure) can also be installed on the back of the robot body 100, and the emergency stop button is electrically connected to the main control board of the chassis 200.

[0085] Specifically, when the emergency stop button is pressed, the main control board controls the motor and the driving wheel 201, and the robot stops moving when an emergency occurs.

[0086] In this embodiment, the robot chassis 200 may also include a speaker (not shown). A microphone 108 is designed and installed below the operating screen 101 as a sound receiving device, and a speaker is installed as a playback device. Both are electrically connected to the industrial computer. The operating screen 101 is electrically connected to the industrial computer and speaker of the robot chassis 200, respectively, to support touch interaction and voice interaction.

[0087] Specifically, the robot's operating screen 101, the receiving microphone 108 and the speaker of the robot chassis 200 are all electrically connected to the industrial computer. The voice content can be input into the industrial computer through the receiving microphone 108 for recognition and feedback. At the same time, the industrial computer operating system is connected to the screen for touch interaction, and the screen displays the user's interactive interface.

[0088] The interactive screen and interactive interface design content provide elderly users with ordering and delivery functions as well as social entertainment functions. The elderly can order according to their needs, and the robot delivers the food to the elderly's dining table through the tray 103. Using the operation screen 101, the radio microphone 108, and the speaker device, the elderly can call up the social entertainment section content in the interactive system through touch interaction and voice interaction during their leisure time for entertainment.

[0089] The meal delivery service system provided by the present invention can realize: safety detection function, the robot integrates multiple sensors to detect the environment in real time, analyzes and processes the quality, image, and abnormal conditions of the environment, such as high-definition cameras can perform all-round scanning and shooting of the environment, smoke sensors and fire sensors can detect air quality and fire and other unexpected situations, and human infrared detectors and cameras can detect whether the elderly have fallen accidentally. When the robot analyzes the data and confirms the occurrence of the situation, it will immediately report it to the management personnel for rescue and service.

[0090] In terms of daily social entertainment for community elderly care users, based on the preferences of elderly users, the robot interaction interface system has set up content sections including chess and card games, film and television operas, calligraphy courses, and music videos. The elderly can use touch screen interaction or voice interaction to control the content, such as opening chess and card games, playing film and television operas, etc. The screen angle is slightly tilted upward to meet the needs of the elderly when watching in a standing or sitting posture.

[0091] The beneficial effects of this meal delivery service system include at least: safety inspection and seat selection for meal delivery. Safety inspection is a deep integration of robots and intelligent environment equipment in the retirement community. When the robot receives an abnormal signal, it will go to the location of the abnormality and confirm the actual situation through fire sensors and smoke sensors and feedback the information to emergency contacts and background administrators. Emergency contacts and retirement community managers can choose to turn on the camera to understand the actual situation and take further measures, ensuring timely response when an accident occurs and protecting the lives of the elderly.

[0092] This utility model addresses the technical issues of busy community nursing homes, which make it difficult for elderly residents to select seats and pick up meals, as well as their difficulty in promptly detecting dangerous environmental changes. The meal delivery service system includes a robot and a camera. The camera displays seat information in real time. A meal delivery tray is installed in the robot's body. The robot follows the user to pick up and pick up meals, and then follows the user to their selected seat, providing smoother and more convenient meal delivery service. The robot also includes a sensor module, a body, an interactive large screen, drawer storage compartments, and a chassis. The sensor module includes a camera, a human detection sensor, a fire sensor, and a smoke sensor. When an accident such as a fall occurs in the community nursing home, the camera automatically activates and performs a visual search, allowing community management personnel to confirm the situation and take appropriate measures, ensuring a timely response to the incident. As elderly residents in the community nursing home engage in daily activities, the human detection sensor detects any abnormal movements and promptly reports back to the backend. When the robot receives a signal of an environmental anomaly, it travels to the location of the anomaly and uses the fire and smoke sensors to confirm the actual situation and report this information back to the backend. Through the use of multiple sensors, timely detection of dangers in the elderly’s living environment is ensured, while the problem of the elderly choosing seats and picking up meals is solved, and the busy service situation of community nursing centers is improved.

[0093] To sum up, this embodiment provides a meal delivery service system. This meal delivery robot system provides intelligent seat selection and meal delivery functions for community nursing homes through fixed cameras, multiple sensors and actuators, which reduces the pressure on service personnel while also providing users with intelligent and personalized service methods.
