[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figures 1 to 5 As shown, a welcoming robot according to the present invention comprises a body, wherein a medium-free holographic projection system for medium-free holographic projection is provided in the body;

[0043] The body is provided with a protrusion, and a first functional area is formed between the protrusion and the body. The first functional area is provided with an auxiliary camera for performing image correction for the environmental camera 16 and the first camera 15, or performing auxiliary recognition when some cameras cannot work normally.

[0044] The first functional area includes a mounting portion 13 and a prompting portion 14. The mounting portion 13 is located above the prompting portion 14. Because it is located above, it can view a downward angle and cooperate with other cameras to perform image verification or image supplementation.

[0045] The auxiliary camera is located in the mounting portion 13; the prompt portion 14 is arranged at an angle to remind the installer that there is a camera in the area or that a camera needs to be installed. When the camera is not installed, the mounting portion 13 can also be used as a handle; and the angle between the prompt portion 14 and the mounting portion 13 is greater than 90°, so as to leave sufficient installation space for the camera.

[0046] The body is detachably connected to a mobile identification chassis 2, which is provided with a second functional area. The second functional area is provided with an inclined collection surface. The collection surface is provided with a first camera 15 for collecting images of the upper environment. The first camera 15 is used to collect images obliquely above the body, and cooperates with the environmental camera 16 to supplement or correct the image so that the image can have a field of view of 120-360°.

[0047] The mobile identification chassis 2 is circumferentially arranged with several groups of environmental cameras 16 for collecting surrounding images. They can be located above or below the first camera 15 , usually above. Each group includes several environmental cameras 16 .

[0048] The mobile identification chassis 2 is provided with a yielding area 17 , and a navigation component is provided in the yielding area 17 .

[0049] A projection area is provided on the top of the body, and a motion sensor is provided in the projection area. In this embodiment, the motion sensor is a common infrared sensor, which is used for gesture recognition or other motion recognition. It can also cooperate with the first camera 15 for gesture recognition or cooperate with the first camera 15 for environmental feature correction.

[0050] The machine body is also provided with a control module 12, a power module, a command module, a display module, a movement module, a broadcast module and a thinking module.

[0051] The control module 12 is used to process data and generate execution commands. The control module 12 includes a data instruction decoding unit, a receiving unit and a positioning unit. The receiving unit is used to receive instructions. The instruction decoding unit converts the instructions into micro-operation sequences. According to the feedback of the micro-operation sequences, the reception robot is controlled to respond.

[0052] The positioning unit is used to obtain the position information of the body shell 1, wherein the positioning unit includes a camera and a positioning chip information interaction component. The positioning chip is a common GPS chip and is arranged inside the body shell 1. The real-time position of the body shell 1 is obtained through positioning the positioning chip to prevent loss.

[0053] The camera is set on the outer wall of the body shell 1. When the positioning chip transmission signal is weak, the camera collects the on-site video information of the location of the body shell 1, and the information interaction component transmits the video to the background, and the staff observes the on-site information.

[0054] The power module is used to provide electrical energy to the control module 12 .

[0055] The command module is used to input commands to the control module 12; the command module includes a key unit 7, a voice unit and an infrared unit, which are respectively adapted to signal input in different ways.

[0056] The button unit 7 is arranged on the outer wall of the body shell 1, and the instructions are input to the receiving unit through the touch button. In this application, the function design of the button strictly follows the actual needs to ensure its accuracy and practicality. During the operation, the user will select the required service items through the button input on the robot to meet the special usage needs of the deaf-mute people. This design aims to provide them with a barrier-free interactive experience and ensure the convenience and efficiency of the service.

[0057] When fingers touch keys, bacteria on fingers will be contaminated on the outer wall of keyboard as they touch. As the user of the welcoming robot is not fixed, in order to reduce the risk of cross infection, the voice unit includes a voice receiving module 8 and a voice decoding module. Voice information is received by the voice receiving unit, and the received voice information is decoded by the voice decoding module to generate electrical information and then fed back to the receiving unit. When in use, the user orally states the required service, receives the voice information through the voice receiving unit, and then sends instructions to the receiving unit through the voice decoding module, so that the welcoming robot can provide the required service, thereby reducing the frequency of contact, preventing cross infection, and realizing simple human-computer interconnection.

[0058] The infrared unit includes an infrared generating module 4 and an infrared receiving module. The infrared generating module 4 emits infrared rays, which are received by the infrared receiving module and converted into electrical signals and fed back to the receiving unit. The light source of the infrared generating module 4 is arranged on the outer wall of the body shell 1. During the movement of the welcoming robot, the infrared generating module 4 emits infrared rays, and obstacles reflect infrared signals, which are received by the infrared receiving module to adjust the movement trajectory of the body shell 1 to prevent collision with pedestrians.

[0059] In order to further improve the service quality of the welcoming robot, the display module projects image information according to the execution command generated by the control module 12. The display module includes a computing unit and a holographic projection unit. The computing unit controls the display unit to project holographic image information according to the micro-operation sequence. When the user selects a service item, the service content is presented through group projection.

[0060] Among them, a sheet metal inner shell 10 is installed at the upper end of the body outer shell 1, and tempered glass 5 and medium-free aerial imaging 6 are arranged on the sheet metal inner shell 10. An infrared sensor 9 is integrated in the control circuit of the medium-free aerial imaging 6. The infrared sensor 9 is used to detect the approach of the user for easy operation. At the same time, a safety switch 3 for controlling the power supply is set on the back of the body outer shell 1; in particular, according to actual use requirements, the medium-free aerial imaging 6 can be set as a functional operation interface, and the medium-free aerial imaging 6 can be operated and the operation process can be identified in combination with the infrared sensor 9, thereby realizing contactless functional operation and further reducing the risk of cross infection.

[0061] In this embodiment, taking querying the destination as an example, the user inputs the destination to be queried by keystroke or voice, and the instruction is received by the receiving unit, decoded by the instruction decoding unit, and transmitted to the computing unit, and finally the display unit projects the map to provide the required service.

[0062] When projecting a map, in order to facilitate itinerary planning, the positioning unit locates the position of the body shell 1 while projecting the map information, and then determines the starting position. The instruction decoding unit plans the itinerary through the starting position and the end position.

[0063] The mobile module controls the movement of the body shell 1 according to the execution command generated by the control module 12. The mobile module includes a driving component and a control unit. The driving component is arranged at the bottom of the body shell 1. The control unit controls the driving component by receiving the data instruction decoding unit signal, wherein the driving component is composed of a motor and a roller. The roller is rotatably arranged at the bottom of the body shell 1. The motor controls the rotation of the roller, thereby controlling the movement of the body shell 1.

[0064] In actual use, by controlling the movement of the housing 1, the loaded items can be moved so as to facilitate access by the user.

[0065] In this embodiment, when the user faces difficulty in interpreting the map, the instruction decoding unit will control the operation of the drive component based on the pre-planned itinerary through the precise scheduling of the control unit, thereby achieving the corresponding movement of the body shell 1. This is intended to provide users with intuitive navigation guidance and highlight the humanized nature of the service.

[0066] When the user places a food order, he or she inputs the desired product through key operation or voice command, and the system will use the mobile function of the housing 1 to realize the rapid transportation of the product, thereby improving the overall service quality. This process is designed to ensure the convenience and efficiency of the service and meet the personalized needs of users.

[0067] During the movement of the body shell 1, in order to ensure its safety, we specially adopt the cooperation mechanism of the infrared generating module 4 and the infrared receiving module. When the infrared receiving module detects an obstacle, it will quickly transmit the detected signal to the instruction decoding unit. Subsequently, the instruction decoding unit will accurately command the driving component to make corresponding route adjustments based on this signal through the control unit to achieve effective avoidance of obstacles, thereby significantly improving the safety of the body shell 1 during the movement.

[0068] A mobile identification chassis 2 is arranged at the bottom of the body shell 1, and a mobile module is arranged on the mobile identification chassis 2, wherein an infrared receiving module is arranged on the outer wall of the mobile identification chassis 2, and a plurality of infrared receiving modules are evenly arranged to improve the receiving range of information.

[0069] In order to further improve the service quality, the broadcast module broadcasts voice information according to the execution command generated by the control module 12. The broadcast module includes a storage unit and a sound unit 11; the sound unit 11 is used to emit acoustic signals, and the storage unit is used for voice packets; according to the data decoded by the instruction decoding unit, the storage unit is controlled to select the voice packet, and the sound unit 11 emits sound, so as to realize human-computer communication through sound, so as to provide better service.

[0070] In order to improve the quality of voice information, a trumpet-shaped groove is provided on the outer wall of the housing 1, and the sound generating unit 11 is arranged inside the groove, thereby improving the quality of voice information.

[0071] In this scenario, we have designed an optimization mechanism for illiterate users. When a user selects a specific service item, the system will use the voice function to broadcast the service content to the user in detail to ensure that the user can fully understand it. At the same time, the user can also provide feedback through voice to make the service more in line with user needs. This is aimed at expanding the scope of application of the service and thus improving the overall service quality.

[0072] The power module includes a battery pack and a control circuit, wherein the battery pack is composed of multiple lithium battery panels, and the control circuit is a common charging and discharging circuit.

[0073] The battery pack outputs power to the control module 12 through the control circuit, and the electric energy stored in the battery pack provides electric energy for the entire electronic components, so that the welcoming robot can provide services.

[0074] At the same time, the control module 12 detects the voltage of the battery pack in real time through the control circuit, decodes it into power information through the instruction decoding unit, and displays it by the holographic projection unit, so that the power information of the robot can be easily grasped in real time.

[0075] During operation, the control module 12 monitors the voltage of the battery pack in real time through the control circuit, and accurately decodes the acquired voltage data into power information through the instruction decoding unit. This information is then clearly displayed by the holographic projection unit to ensure that the staff can intuitively observe the power status, so as to charge the robot in time to ensure its continuous and stable operation.

[0076] The thinking module records the commands output by the instruction module when the control module 12 generates an execution command, establishes a habit model based on the output command, outputs information to the control module 12 according to the habit model, generates a habit model by collecting habits for the selected service, and makes recommendations based on the model, thereby making the service more humane.

[0077] The function of the thinking module is to record in real time the various commands output by the instruction module during the process of the control module 12 generating execution commands. Through these output commands, the thinking module can establish a habit model based on these data. This habit model can output corresponding information to the control module 12 according to the user's usage habits and preferences.

[0078] After the habit model is established, habit data for the selected service is collected. This data will be used to further optimize and adjust the habit model so that it can more accurately reflect the needs and preferences of the user. Based on this habit model that has been continuously optimized and adjusted, the thinking module will output corresponding recommendation information to the control module 12.

[0079] This recommendation method based on the habit model can make the service more humane and more in line with user needs and expectations. Users can also experience a more personalized experience when using the service, thereby improving user satisfaction and loyalty to the service.

[0080] The thinking module includes a feature extraction unit, a modeling unit and a feedback unit. The feature extraction unit is used to extract output instructions of the instruction decoding unit and to record instructions input by the user.

[0081] The modeling unit compiles and statistics the information extracted by the feature extraction unit according to the order of precedence, and establishes a preliminary habit model, thereby obtaining the service content used for selecting a service and the next selection.

[0082] Based on the preliminary habit model, the final habit model is established after invalid data is eliminated, and then the items with a higher proportion are selected according to the proportion. In this embodiment, the items with a proportion of less than 5% are eliminated.

[0083] Among them, let the user choose service A for the first time. After service A, many users choose services B, C, D, ... X. The number of times of each service is:

[0084] B provides b services;

[0085] C served c times;

[0086] D services d times;

[0087] ……;

[0088] X services x times.

[0089] The total number of services is: b+c+d…x times. The proportion is calculated by the ratio of each service number to the total number in order to optimize the data.

[0090] After the instruction decoding unit outputs the instruction, the feedback unit sends an instruction signal to the receiving unit based on the final habit model, and displays the function options through the display unit. During the user's use, when the user enters the service option, the system will synchronously display other available next service options in the habit model through the display unit in real time, thereby providing the user with a clear prompt effect, thereby realizing the diversification and personalization of services.

[0091] In the scenario where the user chooses a sightseeing location, after the user enters his intended destination T, the system will accurately plan the route. After the display unit presents the route planning map, it will simultaneously present the information: "According to historical data, users who have visited T also tend to go to location H." This initiative aims to provide users with more abundant choices while enhancing the interactive experience between humans and machines.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
