[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] The embodiment of the present application provides a mobile robot interactive terminal, which solves the problem that the camera is generally fixedly connected to the shell and cannot be displayed to all viewers during the explanation, reducing the sense of interaction with the audience. At the same time, the driving wheels used for movement during the explanation must be fixed in some way, otherwise safety accidents are more likely to occur.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] The embodiment of the utility model discloses a mobile robot interactive terminal.

[0023] According to the attached Figure 1-5As shown, it includes a terminal 1 and a base 2 arranged at the bottom of the terminal 1, a main shaft 15 is fixedly connected to the bottom of the terminal 1, a circular gear 151 is opened at the lower end of the main shaft 15, an adjustment support assembly 23 is arranged in the base 2, and the adjustment support assembly 23 includes a long rack 231, a double-acting cylinder 232 and a support cross bar 233, the long rack 231 is meshed with the circular gear 151, one end of the double-acting cylinder 232 is arranged on the side wall of the long rack 231, and the other end of the double-acting cylinder 232 is arranged on the top of the support cross bar 233. The main functions of the base 2 are divided into two parts. First, it provides protection and support for the terminal 1, and secondly, it provides fixation and support protection for the adjustment support assembly 23. The adjustment support assembly 23 utilizes the advantage of the two-way output power of the double-acting cylinder 232. Its function is also divided into two aspects. First, the downward lower cabin output rod 2323 is fixedly connected to the support cross bar 233. When the air source inputs the double-acting cylinder 232, the double-acting cylinder 232 is fixedly connected to the support cross bar 233. When the lower cabin of the cylinder 232 is engaged, the lower cabin output rod 2323 overcomes the gravitational potential energy and extends to support the entire terminal 1 and the base 2, so that the terminal 1 and the base 2 are both in contact with the ground by relying on the supporting cross bar 233, and the pulley 22 cannot touch the bottom. During the explanation of the terminal 1, there will be no safety accidents such as the pulley 22 not being fixed and hitting the audience, which plays the role of fixing the terminal 1. Secondly, the inward upper cabin output rod 2322 is fixedly connected to the long rack 231. When the air source is input into the upper cabin of the double-acting cylinder 232, the upper cabin output rod 2322 is driven to extend, and the upper cabin output rod 2322 drives the long rack 231 to move horizontally. The long rack 231 is engaged with the circular gear 151 to convert the horizontal movement force into axial rotation, causing the main shaft 15 to rotate, and finally causing the terminal 1 to rotate. When the terminal 1 is explaining, it can rotate 180 degrees to provide presentations to the audience at different angles and from different aspects, solving the problem of low interactive sense.

[0024] The terminal 1 includes a shell 11, an interactive display screen 12, a camera 13 and an audio device 14. The interactive display screen 12 is fixedly connected to the shell 11, the camera 13 is fixedly connected to the top of the shell 11, and the audio device 14 is arranged in the shell 11. The interactive display screen 12 is the main means of interaction with the audience, the audio device 14 is an auxiliary means of interaction, and the camera 13 is the main means of collection for the terminal 1 to collect audience information.

[0025] Terminal 1 also features an interactive interface equipped with a 55-inch OLED self-luminous capacitive touchscreen, voice recognition module, and facial recognition technology, allowing for interaction with visitors. The digital human can understand verbal commands and provide voice responses or introductions, enhancing interactivity. Pre-programmed or through deep learning technology, the digital human can even display rich facial expressions and body movements, adding realism and interest to the interaction.

[0026] The base 2 also includes a box 21 and a pulley 22. The main shaft 15 is rotatably connected in the box 21, and the pulley 22 is rotatably connected to the bottom of the box 21. The pulley 22 enables the mobile robot interactive terminal to move, thereby improving the scope of use and interaction efficiency.

[0027] Using SLAM (Simultaneous Localization and Mapping) technology, digital humans can create maps and determine their own positions in unknown environments. Combined with known maps, they can perform path planning and achieve autonomous navigation from their current location to their destination. Based on AI algorithms, Dijkstra algorithms, or more advanced path planning algorithms, the most optimized route is calculated for the digital human, taking into account factors such as efficiency, safety, and visiting experience. This allows the digital human to better guide the audience and act as a tour guide. The digital human also collects visitor behavior data, analyzes visiting paths, duration of stay, etc., to optimize guided routes and service content.

[0028] The long rack 231 , the double-acting cylinder 232 and the supporting cross bar 233 are each provided in two groups correspondingly.

[0029] The double-acting cylinder 232 includes a double-cabin cylinder body 2321, an upper cabin output rod 2322, a lower cabin output rod 2323 and an air inlet and outlet hole 2324. The upper cabin output rod 2322 and the lower cabin output rod 2323 are slidingly connected in the double-cabin cylinder body 2321. The air inlet and outlet holes 2324 are opened on the side of the double-cabin cylinder body 2321. The air source draws compressed air into the air cabin through an external compressor to push the piston to move. The piston drives the upper cabin output rod 2322 and the lower cabin output rod 2323 to move. This power enables the adjustment support assembly 23 to operate normally.

[0030] The double-cabin cylinder 2321 is fixedly connected in the box body 21 , the upper cabin output rod 2322 is fixedly connected to the side end of the long rack 231 , and the lower cabin output rod 2323 is fixedly connected to the top of the supporting cross bar 233 .

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions merely illustrate the principles of the present invention.
