[0019] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0020] like Figures 1 to 4 As shown, an interactive role-playing dialogue robot in one embodiment of the present invention includes a mobile base 100 and a control terminal 120. The bottom of the mobile base 100 is equipped with drive wheels 1001, which are driven by a motor to move. The mobile base 100 can move autonomously. A support rod 110 is fixed on the mobile base 100, and a display screen 140 is fixed on the support rod 110. The display screen 140 is used by learners to perform scene learning operations, display dialogue content, practice exercises, etc. The display screen 140 has a slot on its side, through which a memory card is inserted. The memory card can store a large number of question banks and words, which is convenient for learners to practice. The control terminal 120 includes an input processing module, a dialogue management module, a course and content management module, and an output generation module. The input processing module is used to convert the learner's voice input into text in real time and perform in-depth analysis on the converted text. The control terminal 120 is used to receive dialogue information, process the dialogue information, and convert the dialogue information into text and transmit it to the display screen 140. The control terminal 120 is fixed with a projection unit 130, which is used to project the dialogue scene onto a wall or a screen. That is, the scene can be projected onto a screen or onto a wall. The wall is preferably a white wall, which can reduce the need for a screen. The projection unit 130 includes a projector 131, which is electrically connected to the output generation module via a circuit. The output generation module can retrieve scene images according to the received instructions and project the scene images through the projector 131 to enhance learners' interest and deepen their memory of words.

[0021] In the above embodiment, the learner selects a specified scene for learning on the display screen 140. The course and content management module is triggered, extracts keywords from the scene, and sends the extracted keywords to the dialogue management module. After receiving the dialogue content, the dialogue management module sends an instruction to the output production module. The natural language generation component in the output generation module starts working, converting the text into friendly and professional speech according to the received instruction. At the same time, the output generation module retrieves scene images from the course and content management module and projects the scene images through the projector 131. The speech and text subtitles are presented on the display screen 140. The learner responds with speech based on the displayed information. At this time, the natural language generation component in the input processing module starts working, converting the learner's speech into text. After in-depth analysis of the converted text, key information is extracted and sent to the dialogue management module. The dialogue management module sends a teaching instruction to the output generation module. After receiving the instruction, the output generation module converts it into a natural, role-appropriate, and instructionally designed dialogue. This process is repeated, creating a highly immersive learning environment, breaking through screen limitations, achieving more natural and social interaction, reducing cognitive load, improving understanding, and deepening memory.

[0022] In some embodiments of this application, such as Figures 1 to 4 As shown, the projection unit 130 also includes a rotating rod 132 and a driving unit 133; The drive unit 133 includes a mounting base and a micro stepper motor. The mounting base is fixed to the top of the control terminal 120, and the micro stepper motor is fixed inside the mounting base. The output end of the micro stepper motor is connected to the rotating rod 132. The unused end of the rotating rod 132 is fixed to the bottom of the projector 131.

[0023] Based on the above embodiments, the drive unit 133 can drive the rotating rod 132 to rotate, thereby driving the projector 131 to rotate, which facilitates the adjustment of the projection angle and can achieve a surround effect of the projection.

[0024] Specifically, such as Figure 4 As shown, a camera 121 is fixed to one end of the control terminal 120. The camera 121 is used to detect the learner's facial expressions and movements. The learner can respond to questions in the situation through movements. A groove is opened on the end of the control terminal 120 near the camera 121, and a metal plate is fixed in the groove. A speaker 122 is positioned on the control terminal 120. The speaker 122 is electrically connected to the control terminal 120 via a Bluetooth connection module. A magnet is fixed on the speaker 122 near the groove. The magnet can be magnetically attracted to the metal plate.

[0025] It is easy to understand that the speaker 122 converts the received electrical signal, that is, the dialogue information, into mechanical vibration, which in turn drives the air to generate sound waves, thereby realizing the playback or amplification of sound. The speaker 122 is detachable and can be placed in any position. When there are many people learning, the speaker 122 can be placed in a more central position so that most people can hear it.

[0026] Specifically, such as Figure 9 and Figure 10 As shown, a shield 170 is movably hinged to the control terminal 120 at a position away from the camera 121. The shield 170 includes a long plate and a short plate. The long plate is movably hinged to the control terminal 120, and the short plate is fixed to the unused end of the long plate. A limiting groove 171 is opened on the long plate away from the control terminal 120. A limiting block 172 is fixed on the control terminal 120 near the long plate. After the long plate is flipped upward, the limiting groove 171 can be locked into the limiting block 172.

[0027] It should be noted that after the shield 170 is flipped, the short plate can be located above the projector 131, and the long plate is located on the side of the lens of the projector 131. In the initial state, the lens of the projector 131 faces the direction of the long plate. The shield 170 protects the lens of the projector 131 and prevents the lens from being damaged.

[0028] Specifically, such as Figures 1 to 6 As shown, positioning seats 150 are fixed on both sides of the movable base 100, and a telescopic cylinder 152 is fixed on the top of the positioning seat 150. A positioning plate 151 is fixed on the empty end of the telescopic cylinder 152. An air supply unit 160 is fixed on the support rod 110. The air supply unit 160 is used to supply air to the telescopic cylinder 152, so that it stretches and drives the positioning plate 151 to descend, supporting the movable base 100 and positioning the equipment through the positioning plate 151.

[0029] It is easy to understand that the robot can be driven to walk by the drive wheel 1001 inside the mobile base 100. After the robot stops walking, in order to ensure the stability of the robot, the air supply unit 160 inflates the telescopic cylinder 152 to stretch it, which in turn drives the positioning plate 151 to descend and lift the mobile base 100 away from the table or the ground.

[0030] In some embodiments of this application, such as Figures 1 to 8 As shown, a protective part 142 is fixed on one side of the display screen 140; The protective part 142 includes a fixing plate 1421 and a support plate 1422; The support plate 1422 is fixed on one side of the display screen 140, and the fixing plate 1421 is fixed on the other side of the support plate 1422. A telescopic strap 1423 is fixed on the side of the fixing plate 1421 near the display screen 140. The telescopic strap 1423 can extend and retract, and the extended and retracted telescopic strap 1423 can cover the surface of the display screen 140. A movable plate 1425 is fixed to the other side of the telescopic belt 1423, and the telescopic belt 1423 is located in front of the display screen 140.

[0031] Specifically, such as Figures 1 to 8 As shown, a limiting plate 141 is fixed on the side of the display screen 140 away from the support plate 1422, and a magnetic plate is fixed on the movable plate 1425 near the limiting plate 141. The limiting plate 141 is a metal plate, and the movable plate 1425 can be magnetically attracted to the limiting plate 141.

[0032] It is easy to understand that after the telescopic belt 1423 is stretched, the movable plate 1425 can be positioned on the limiting plate 141, which facilitates the positioning of the movable plate 1425. The structure is simple and easy to operate.

[0033] Specifically, such as Figures 6 to 8 As shown, a card plate 1424 is fixed on the support plate 1422, and a slot is opened on the moving plate 1425 near the card plate 1424. The card plate 1424 is inserted into the slot. That is to say, in the initial state, the moving plate 1425 is fixed by the card plate 1424, and the card plate 1424 is located on one side of the display screen 140, which does not affect the use of the display screen 140. A placement box 180 is fixed to one end of the support rod 110 away from the display screen 140. The placement box 180 is used to place learning materials.

[0034] Specifically, such as Figure 7 and Figure 8 As shown, the movable plate 1425 is a hollow plate, and multiple nozzles 1426 are fixed at even intervals near the display screen 140. A brush 1427 is fixed on the side of the movable plate 1425 away from the telescopic belt 1423. The brush 1427 contacts the surface of the display screen 140 and is used to clean the dust on the display screen 140. The brush 1427 is soft and will not damage the screen.

[0035] Specifically, such as Figures 3 to 9 As shown, the air supply unit 160 includes an air supply pipe 161 and an air pump. The air pump is fixed on the support rod 110. The air inlet end of the air supply pipe 161 is connected to the air pump. The air pump is electrically connected to the control terminal 120 through a circuit. The air pump can be started by issuing a command through voice control. A branch pipe 162 is fixed on the air supply pipe 161, and a valve is fixed on the branch pipe 162. Branch pipe 162 has two air outlets, and one air outlet of branch pipe 162 supplies air into a telescopic cylinder 152. An air supply pipe 163 is fixed on the air supply pipe 161, and a valve is fixed on the air supply pipe 163. The air outlet end of the air supply pipe 163 extends into the movable plate 1425. The air supply pipe 163 is a flexible hose that can adapt to the reciprocating movement of the movable plate 1425. It is easy to understand that when the valve of branch pipe 162 is opened, airflow enters branch pipe 162, and when the valve of vent pipe 163 is opened, airflow enters vent pipe 163.

[0036] Based on the above embodiments, when cleaning the surface of the display screen 140, firstly, the slot of the moving plate 1425 is disengaged from the card plate 1424, and the moving plate 1425 is pulled to move on the surface of the display screen 140. The brush 1427 first sweeps away the dust on the surface of the display screen 140. As the telescopic belt 1423 unfolds, the air pump is started at the same time, the valve of the vent pipe 163 is opened, and the valve of the branch pipe 162 is closed. The airflow enters the moving plate 1425 and sprays clean airflow on the surface of the display screen 140 through the nozzle 1426. By repeatedly moving the moving plate 1425, the surface of the display screen 140 can be cleaned. When not in use, the moving plate 1425 can be pulled directly to be adsorbed onto the limiting plate 141, so that the telescopic belt 1423 blocks the front of the display screen 140, which can protect the display screen 140 and prevent foreign objects from directly scratching the display screen 140, thereby improving its service life.

[0037] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics.
