Description

Technical Field

[0001] This invention relates to the field of tour guide robot technology, specifically a tour guide robot for tourism management. Background Technology

[0002] A tour guide robot is a type of service robot used for reception and tour guide services at exhibition venues.

[0003] Chinese invention patent CN111391941B discloses a tourist service robot for scenic areas, comprising a drive chassis and a luggage fixing device mounted on the drive chassis. The luggage fixing device includes an upper base plate and a lower base plate arranged opposite each other, connected by a lifting mechanism to adjust the height between the upper and lower base plates. Both ends of the bottom of the upper base plate are provided with fixing baffle mechanisms that contact the side walls of the luggage to fix the luggage. The tourist service robot provided by this invention has luggage handling capabilities, effectively reducing the burden on tourists and enhancing their travel experience. Furthermore, the self-locking lifting mechanism reduces the space required to place the tourist service robot, and the fixing baffle mechanism not only fixes luggage but also allows the tourist service robot to adapt to fixing luggage of different sizes, increasing its applicability. The dual-wheel differential drive chassis enables the tourist service robot to turn in confined spaces.

[0004] Chinese invention patent CN113075956A discloses a map robot for rural tourism, comprising a base and a robot torso. Robot upper limbs are mounted on the torso, and a touchscreen display is supported on each upper limb. A cavity is formed within the torso, housing a robot host connected to the touchscreen display. The robot host includes a processor, a data acquisition module for collecting input commands from the touchscreen display, and an output module for outputting maps and attraction information. The robot host projects the map and attraction descriptions onto the touchscreen display. Tourists input attraction names via the touchscreen display. The data acquisition module collects the commands from the touchscreen display and transmits them to the processor. The processor then outputs the relevant attraction information to the touchscreen display via the output module, allowing tourists to plan their routes and enhance their travel experience.

[0005] Chinese invention patent CN110884586B discloses an intelligent bionic robot for travel companionship. By incorporating a lower limb rolling component and a lower leg rotation component into the robot's walking device, the robot achieves movements such as turning and leg lifting. This enables the robot to climb stairs and walk on sloping roads, expanding the companionship range of the robot, providing better service to tourists, and reducing service costs. Furthermore, the use of pull wheels and pull lines for force transmission results in a structure with lower complexity than gear structures and higher stability than conveyor belt structures, improving the safety and stability of the robot's walking and stair climbing processes. In addition, the use of dedicated motors for individual control of different functional components increases the robot's mobility.

[0006] In some large scenic areas, tour guide robots are used to facilitate tourists' visits and guide them through the area.

[0007] However, the existing tour guide robots are all driven by tires. In some areas of the scenic area where climbing stairs is required, the tour guide robots have difficulty moving on the stairs. They can only be placed on separate tracks or moved over the stairs. The existing tour guide robots cannot climb stairs on their own, which reduces the effectiveness of the tour guide robots.

[0008] Furthermore, existing tour guide robots can only introduce attractions in a scenic area when tourists manually select or ask questions. They cannot automatically identify attractions and introduce the current location after the tour has taken place. Also, they cannot display objects in the distance of the attractions in real time when tourists want to see them. Summary of the Invention

[0009] The purpose of this invention is to provide a tour guide robot for tourism management to solve the problems mentioned in the background art.

[0010] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a tour guide robot for tourism management, comprising: Base; The adjustable wheels located below the base are used to enable the robot to climb the steps; The base is internally connected to the top of the bracket via fasteners. One end of the bottom of the bracket is rotatably connected to the top of the support block. The support block is connected to a rotating rod via a rotating shaft. Both ends of the rotating rod are connected to a first toothed ring via fasteners. The side of the bracket is rotatably connected to the top of the support column. The bottom of the support column is rotatably connected to the top of the telescopic column. The bottom of the telescopic column is rotatably connected to the support block. The top of the base is equipped with a fixed column. The outer walls of the fixed column are equipped with landscape cameras on both sides. A display screen is installed on the back of the fixed column, and a speaker is fixedly connected to the display screen.

[0011] Preferably, the first gear meshes with the first gear, the side of the first gear is connected to the first motor by fasteners, the first motor is connected to the inner wall of the support block by fasteners, the adjusting wheel is wrapped with a track, and the rear of the bracket is connected to the support wheel by rotation.

[0012] Preferably, the outer wall of the support column is connected to the cylinder via fasteners, the output end of the cylinder is connected to the outer wall of the telescopic column via fasteners, the cylinder is connected to the air pump via a pipe, and the outer wall of the base is connected to the back of the photovoltaic panel via fasteners.

[0013] Preferably, the top of the base is connected to the battery via fasteners, the top of the base is connected to the bottom of the fixing column via fasteners, the outer wall of the fixing column is connected to the sliding ring via rotation, and the outer wall of the sliding ring is connected to the landscape camera via fasteners.

[0014] Preferably, a vision camera is connected to the top of the fixed column via fasteners, and the vision camera and the landscape camera are respectively connected to a chip via wiring. The chip is connected to the inner wall of the fixed column via fasteners.

[0015] Preferably, the inner wall of the slip ring is connected to the second gear ring by fasteners, the inner side of the second gear ring meshes with the second gear, the top of the second gear is connected to the output shaft of the second motor by fasteners, and the second motor fasteners are connected to the inner wall of the fixed column.

[0016] Preferably, the support wheel structure is the same as the adjustment wheel structure, and the support wheel and the adjustment wheel are symmetrically distributed inside the base.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention, by incorporating adjustable wheels and telescopic columns, enables the robot to climb stairs within scenic areas. When the robot moves to a staircase, a vision camera on top detects its movement and, under chip control, activates a cylinder. The cylinder retracts, causing the telescopic column to move. This telescopic column then lifts the front end of a support block, which in turn lifts the adjustable wheels and tracks. The first motor inside the support and adjustable wheels then activates, driving a first gear via its output shaft. This gear, through a first gear ring, drives a rotating rod and the adjustable wheel. The adjustable wheel, via the tracks, propels the robot forward. Once the bottom of the lifted adjustable wheel rests on the edge of the staircase, the support and adjustable wheels continue to rotate. As the robot moves along the stairs, the cylinder gradually pushes the adjustable wheel until the support and adjustable wheels are parallel to each other. This achieves the goal of enabling the tour guide robot to climb stairs within scenic areas, demonstrating the robot's effectiveness.

[0018] Secondly, by incorporating a landscape camera and pulleys, this invention enables real-time introductions and displays of scenic spots at the location. After the robot moves to a scenic spot, the landscape camera captures images of the spot and identifies it using pre-stored information within the chip. Then, a speaker on the display screen introduces the scenic spot. Simultaneously, the chip controls a second motor to rotate a second gear, which in turn rotates a sliding ring via a second gear ring. The sliding ring then drives the landscape camera on it to capture images of the surrounding scenery, which are then displayed on the screen for tourists. This allows the robot to introduce different scenic spots as it moves to them, and the images captured by the landscape camera are displayed on the screen, enabling tourists to view distant scenery in real-time, demonstrating the multifunctionality of this device.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please see Figure 1-8 A tour guide robot for tourism management, comprising: Base 1; The adjustment wheel 13 is located below the base 1. The adjustment wheel 13 is used to enable the robot to climb the steps. The base 1 is internally connected to the top of the bracket 9 via fasteners. One end of the bottom of the bracket 9 is connected to the top of the support block 14 via a rotating mechanism. The support block 14 is connected to the rotating rod 18 via a rotating shaft. Both ends of the rotating rod 18 are connected to the first gear ring 19 via fasteners. The side of the bracket 9 is connected to the top of the support column 15 via a rotating mechanism. The bottom of the support column 15 is connected to the top of the telescopic column 16 via a rotating mechanism. The bottom of the telescopic column 16 is connected to the support block 14 via a rotating mechanism. The top of the base 1 is provided with a fixed column 2. The outer walls of the fixed column 2 are provided with landscape cameras 4. The back of the fixed column 2 is provided with a display screen 10. A speaker 11 is fixedly connected to the display screen 10.

[0023] When the robot moves to the steps, the visual camera 3 on top of the robot detects that it has moved to the steps. Controlled by chip 8, cylinder 17 is activated, causing it to retract and move the telescopic column 16. The telescopic column 16 causes the front end of the support block 14 to tilt upwards. The support block 14 then causes the adjusting wheel 13 and track 7 on it to tilt upwards. The first motor 21 inside the support wheel 12 and adjusting wheel 13 is then activated. The first motor 21 drives the first gear 20 to rotate via its output shaft. The first gear 20 drives the rotating rod 18 and the adjusting wheel 13 on it to rotate via the first gear ring 19. The adjusting wheel 13 moves the robot via the track 7. After the bottom of the tilted adjusting wheel 13 rests on the edge of the steps, the support wheel 12 and adjusting wheel 13 continue to rotate. During the movement up the steps, the control cylinder 17 gradually pushes the adjusting wheel 13 until the support wheel 12 and adjusting wheel 13 are parallel to each other on the steps. This enables the tour guide robot to climb the steps inside the scenic area, demonstrating the effectiveness of the tour guide robot. Example 2: Specifically, the first gear ring 19 meshes with the first gear 20, the side of the first gear 20 is connected to the first motor 21 by fasteners, the first motor 21 is connected to the inner wall of the support block 14 by fasteners, the adjusting wheel 13 is wrapped with the track 7, the rear of the bracket 9 is connected to the support wheel 12 by rotation, the outer wall of the support column 15 is connected to the cylinder 17 by fasteners, the output end of the cylinder 17 is connected to the outer wall of the telescopic column 16 by fasteners, the cylinder 17 is connected to the air pump through the pipe, and the outer wall of the base 1 is connected to the back of the photovoltaic panel 6 by fasteners.

[0024] Through the above technical solution,

[0025] Specifically, the top of the base 1 is connected to the battery 25 by fasteners, the top of the base 1 is connected to the bottom of the fixing column 2 by fasteners, the outer wall of the fixing column 2 is connected to the sliding ring 5 by rotation, the outer wall of the sliding ring 5 is connected to the landscape camera 4 by fasteners, the top of the fixing column 2 is connected to the vision camera 3 by fasteners, the vision camera 3 and the landscape camera 4 are respectively connected to the chip 8 by wires, and the chip 8 is connected to the inner wall of the fixing column 2 by fasteners.

[0026] Through the above technical solution, the vision camera 3 is used to continuously acquire video streams in front of the robot, mainly for identifying walkable paths, detecting obstacles, and recognizing directional markers. The chip 8 first analyzes the images captured by the vision camera 3, which is the highest priority decision. If an obstacle is detected, obstacle avoidance strategies such as stopping or detouring are immediately triggered to ensure safety. When there are no obstacles, instructions for moving forward or fine-tuning the direction are generated based on the preset route or the identified path features such as lane lines and road edges. The built-in AI model, such as a CNN convolutional neural network, is used to analyze the images in real time to identify specific scenic spots such as "Lion Peak", objects such as "ancient pine", or scenes such as "waterfall". The identification results are matched with the narration dictionary. If a scenic spot is matched, the narration process is triggered. If no specific target is identified, the default state is maintained. When receiving motion instructions of speed and direction from the decision layer, the speed and steering of the seven tracks are precisely controlled by the motor driver to achieve actions such as moving forward, backward, turning, and stopping. When the narration is triggered, the corresponding narration audio and high-definition images / videos are retrieved from the dictionary. The relevant images are displayed on the rear display screen 10, and the narration is played through the speaker. At the same time, the moving camera can be controlled to pause its swing and focus on the identified target, providing a more stable image. When there is no narration, the display screen 10 can display the robot logo, welcome message, map, or real-time view of the side cameras. After completing a round of actions, the process immediately returns to the beginning of the main control loop, re-collects perception data, and starts a new round of "perception-decision-execution" process. This high-frequency loop ensures the robot's real-time response to the dynamic environment.

[0027] Example 3: Specifically, the inner wall of the sliding ring 5 is connected to the second gear ring 22 by fasteners, the inner side of the second gear ring 22 meshes with the second gear 23, the top of the second gear 23 is connected to the output shaft of the second motor 24 by fasteners, the second motor 24 is connected to the inner wall of the fixed column 2 by fasteners, the structure of the support wheel 12 is the same as that of the adjusting wheel 13, and the support wheel 12 and the adjusting wheel 13 are symmetrically distributed inside the base 1.

[0028] Through the above technical solution, the landscape camera 4 and the vision camera 3 are used to collect all sensor data. The processor on chip 8 then makes core decisions, receives execution instructions, and drives hardware execution, such as moving the support wheels 12 and adjustment wheels 13, rotating the camera, playing audio, and refreshing the screen. By preseting the scenery on both sides to oscillate periodically, the field of view is expanded and the probability of capturing spectacular scenery is increased. The main control chip 8 and the system enter an infinite loop, enabling the robot to work continuously. Before using the robot, preset guide route maps, scenic spot explanation databases, image recognition models, and other data need to be loaded in advance. An image recognition system is also installed inside the robot's fixing column 2. AI Recognition: This is the core of the system's "intelligence," requiring pre-training on a large number of scenic spot images to achieve high recognition accuracy. Sensor Fusion: For more reliable navigation, an IMU (Inertial Measurement Unit) is added to the bottom to sense slope and stability, or a LiDAR is added for precise obstacle avoidance. Priority Management: The system clearly defines the safety priority principle as obstacle avoidance > navigation > explanation. At any time, safety-related decisions have the highest interruption priority. The photovoltaic panel 6 is connected to the battery 25 through the junction box on its back. The battery 25 is connected to each drive device through lines to increase the robot's endurance. The motor and output shaft are integrated; the motor rotates through the output shaft, and the motor is a servo motor.

[0029] In operation, the robot's top vision camera 3 first detects that it has moved to a step. Controlled by chip 8, cylinder 17 is activated, causing it to retract and move telescopic column 16. Telescopic column 16 causes the front end of support block 14 to tilt upwards, which in turn causes the adjusting wheel 13 and track 7 on it to tilt upwards. Then, the first motor 21 inside support wheel 12 and adjusting wheel 13 is activated. The first motor 21 drives the first gear 20 to rotate via its output shaft. The first gear 20, through the first gear ring 19, drives the rotating rod 18 and the adjusting wheel 13 to rotate. The adjusting wheel 13, through the track 7, propels the robot forward. After the bottom of the tilted adjusting wheel 13 rests on the edge of the step, the support wheel 12 and adjusting wheel 13 continue to rotate. During the movement up the step, cylinder 17 gradually pushes the adjusting wheel 13. 3. Until the support wheel 12 and the adjusting wheel 13 are parallel on the steps, after the robot moves to the scenic spot, the landscape camera 4 captures the scenic spot at its location. By identifying the information stored in the chip 8, the speaker 11 on the display screen 10 introduces the scenic spot. At the same time, the chip 8 controls the second motor 24 to drive the second gear 23 to rotate. The second gear 23 drives the sliding ring 5 to rotate through the second gear ring 22. The sliding ring 5 drives the landscape camera 4 on it to capture the scenery of the surrounding scenic spots and then display it to tourists on the display screen 10. When moving to the scenic spot, the robot can introduce the scenic spot according to its location. At the same time, the images captured by the landscape camera 4 are displayed on the display screen 10 so that tourists can view the scenery in the distance in real time. This completes the work.
