Considering that the user may stand at any position next to the body 2 when using it, the speaker 11 can achieve the best use effect at this time.

[0038] Embodiment 3

[0039] Figure 4 and Figure 5 As shown, a plurality of shields 9 are evenly and fixedly connected to the inner bottom of the annular frame 8. The shields 9 are located below the speaker 11. A microphone 10 is fixedly connected to the inner surface of the shields 9. The microphone 10 is electrically connected to the speaker 11. The shields 9 are in a conical shape that opens outward.

[0040] In the present embodiment, by installing a plurality of shields 9 and microphones 10 in a circumferentially distributed manner on the inner side of the annular frame 8, when the user uses the service robot to speak and input commands, the plurality of shields 9 and microphones 10 can be used respectively to collect voice commands at different angles.

At this time, the control system can judge the size of the audio collected by each microphone 10, and the position of the user's body 2 can be known. At this time, the control system can control the movement of the robot according to the user's position, so that the robot moves to a state where the display screen 7 is facing the user. At this time, the display screen 7 can better meet the use requirements and improve the service quality of the service robot.

[0041] The method of use and working principle of the device: When the voice recognition control service robot is used, the support component 3, the positioning component 4 and the obstacle crossing component 5 are used in combination to support the base 1 and the body 2 to move, so that the body 2 moves to the customer's location for service. When the body 2 moves to the customer's location for service, the operation page of the corresponding service information can be displayed through the use of the display screen 7. The display screen 7 uses a touch screen, which can provide users with operation after displaying the service information. At the same time, through the combination of the microphone 10 and the speaker 11, the voice recognition control function can be provided for the body 2. After the user speaks, the sound is collected by the microphone 10, and the microphone 10 collects the sound and inputs it to the display screen. The operating system of 7 performs preprocessing such as filtering and framing on the collected voice signal to extract effective voice features, and then converts the preprocessed voice signal from the time domain to the frequency domain to extract voice features such as phonemes, pitch, and sound intensity. The acoustic model calculates the score of each feature vector according to the acoustic characteristics, and the language model calculates the probability of the corresponding possible phrase sequence according to linguistic theory, decodes the phrase sequence in combination with the dictionary, and finally outputs the recognition result. The output result is converted into instruction information and entered into the operating system of the display screen 7. At this time, the display screen 7 displays the corresponding service information and performs the corresponding task according to the collected voice information. At the same time, the operating system of the display screen 7 can control the speaker 11 to play the corresponding response. The loudspeaker 11 adopts a circular arrangement of multiple playback elements. Since the circular loudspeaker 11 has a uniform diaphragm distribution in all directions, it can provide a more balanced and consistent sound performance, so that the sound emitted by the loudspeaker 11 can evenly cover various positions around the body 2. Considering that the user may stand at any position next to the body 2 when using it, the loudspeaker 11 can achieve the best use effect at this time, thereby improving the service quality of the service robot. By installing multiple shields 9 and microphones 10 in a circular distribution on the inner side of the ring frame 8, when the user uses the service robot to speak and enter commands, multiple sets of shields 9 and microphones 10 can be used respectively to collect voice commands at different angles. When the robot is used at any position around the user's body 2, multiple microphones 10 will collect audio information respectively. At this time, the use of the shield 9 can shield the microphone 10 inside the shield 9 from the influence of audio at other angles. At this time, the control system can judge the size of the audio collected by each microphone 10, and the position of the user's body 2 can be known. At this time, the control system can control the movement of the robot according to the user's position, so that the robot moves to a state where the display screen 7 is facing the user. At this time, the display screen 7 can better meet the use requirements and improve the service quality of the service robot. When the service robot moves, through the cooperation of the third motor 506 and the fourth motor 516,After the third motor 506 is running, it can drive the first driving wheel 508 to follow the rotation through the connection with the first rotating shaft 507. After the fourth motor 516 is running, it can drive the second driving wheel 517 to follow the rotation through the connection with the second rotating shaft 514. At this time, through the synchronous rotation of the first driving wheel 508 and the second driving wheel 517, the first driving wheel 508 and the second driving wheel 517 can drive the robot to walk in contact with the ground. When the direction needs to be changed during the walking process, the operation of the first motor 305 can drive the gear 306 to follow the rotation. When the gear 306 rotates, it meshes with the gear ring 307 and cooperates with the first rotating seat 301, the support rod 302 and the second rotating seat 303, so that the moving seat 304 and the base 1 are at the same time. In the rotating state, the gear 306 meshes with the driving gear 306, which can achieve the purpose of driving the moving seat 304 to rotate. The moving seat 304 drives the first driving wheel 508 and the second driving wheel 517 below it to rotate accordingly, so as to achieve the purpose of changing the moving direction of the robot. When the robot passes through obstacles such as thresholds during its movement, the robot can be controlled to cross the obstacles to complete its movement through the coordinated use of the support component 3, the positioning component 4 and the obstacle-crossing component 5, so as to avoid the robot directly crossing the obstacle to generate large bumps and vibrations that affect the stability of the internal components, thereby achieving the purpose of prolonging the service life of the robot. When the robot moves to a position close to the obstacle, the second driving wheel 517 on the outside moves to the side of the obstacle, and the two sets of first driving wheels 5 08 and the second driving wheel 517 are respectively provided with height support by two damping rods 308. The damping rod 308 is connected with the inner frame 502 to provide height support for the inner frame 502, the linkage frame 501 and the outer frame 509. When obstacle avoidance displacement is required, the second motor 402 is started. After the second motor 402 is running, it can drive the driving shaft 403 to rotate accordingly. The rotation of the driving shaft 403 drives the rotating wheel 404 and the tooth block 405 to rotate accordingly. At this time, the rotating wheel 404 rotates to one side of the moving direction. After rotating a certain angle, the tooth block 405 meshes with the tooth plate 504 at the corresponding position. At this time, as the rotating wheel 404 rotates, the tooth plate 504 can be pushed to move up, and the tooth plate 504 can drive the inner frame 502 to move up through the connection of the extension rod 503. The inner frame 502 moves upward, and at this time, a group of first driving wheels 508 and second driving wheels 517 can be driven to move upward to a state above the obstacle. After the group of first driving wheels 508 and second driving wheels 517 move upward, another group of first driving wheels 508 and second driving wheels 517 are in a ground-contacting state to provide support for the robot. At this time, the third motor 506 and the fourth motor 516 at the ground position are started to drive, so as to drive the second driving wheel 517 in the moving direction to cross the obstacle. Then, the second motor 402 is controlled to run in the reverse direction, and the rotation of the rotating wheel 404 can drive the toothed plate 504 on one side of the traveling direction to move downward, and then drive the toothed plate 504 on the other side to move upward. At this time, another group of third motors 506 and fourth motors 516 cooperate to operate.It can drive the first driving wheel 508 to move across the obstacle, and then through the coordinated operation of the second motor 402, the third motor 506 and the fourth motor 516, the robot can be driven to move across the obstacle without causing bumps, effectively avoiding the problem of vibration caused by bumps during the displacement of the robot, and improving the service life of the robot.
