　　設計藍圖規劃

　　Design blueprint planning

　　制作大型機器人模型伊始，需精心繪制設計藍圖。借助 CAD（計算機輔助設計）軟件，設計人員依據預期用途、展示場景及審美需求，構建機器人三維模型。若為工業主題展示，機器人設計可能側重機械結構外露，凸顯力量感與科技感，精確標注各部件尺寸、形狀及相互連接關系；若是兒童樂園互動型機器人，造型則趨向圓潤可愛，色彩鮮艷，同時兼顧內部空間布局，為后續電子設備安裝預留位置。設計過程中，充分考量材料特性與加工工藝可行性，確保設計方案可落地實施。

　　At the beginning of making a large robot model, it is necessary to carefully draw a design blueprint. With the help of CAD (Computer Aided Design) software, designers construct 3D models of robots based on their intended use, display scenarios, and aesthetic needs. If it is an industrial themed exhibition, robot design may focus on mechanical structure exposure, highlighting the sense of power and technology, and accurately marking the dimensions, shapes, and interconnection relationships of each component; If it is an interactive robot in a children's playground, its shape tends to be round and cute, with bright colors, while also considering the internal space layout and reserving space for the installation of electronic devices in the future. In the design process, fully consider the material characteristics and feasibility of processing technology to ensure that the design scheme can be implemented on the ground.

　　材料精挑細選

　　Carefully selected materials

　　材料選擇對大型機器人模型至關重要。結構框架常用金屬材料，如鋁合金，其質輕且強度高，能支撐起龐大身軀，保證模型穩定性，又可減輕整體重量，降低運輸與安裝難度。對于外殼部分，若追求逼真金屬質感，可選用不銹鋼薄板，經切割、彎折、焊接等工藝，塑造出機器人外殼輪廓；若需降低成本且兼顧造型靈活性，玻璃鋼材料是不錯選擇，它可通過模具成型，制作出復雜形狀，表面再經噴漆處理，模擬各類材質效果。此外，3D 打印技術興起后，一些復雜零部件，如關節連接件、裝飾部件等，可使用工程塑料（如尼龍、ABS 等）通過 3D 打印制作，精準實現設計形狀。

　　Material selection is crucial for large robot models. Metal materials commonly used in structural frameworks, such as aluminum alloys, are lightweight and have high strength. They can support large bodies, ensure model stability, reduce overall weight, and lower transportation and installation difficulties. For the shell part, if you pursue a realistic metallic texture, you can choose stainless steel sheet and shape the outline of the robot shell through cutting, bending, welding and other processes; If you need to reduce costs while also considering flexibility in design, fiberglass material is a good choice. It can be molded into complex shapes through molds, and the surface can be spray painted to simulate the effects of various materials. In addition, with the rise of 3D printing technology, some complex components such as joint connectors and decorative parts can be made using engineering plastics (such as nylon, ABS, etc.) through 3D printing to achieve precise design shapes.

　　加工與組裝工序

　　Processing and assembly procedures

　　材料備好后進入加工環節。金屬材料借助激光切割設備，依據設計圖紙精確切割成所需形狀；折彎機對薄板進行彎折，塑造機器人外殼弧度；焊接工藝將各金屬部件牢固連接，確保結構強度。對于 3D 打印部件，需提前對模型進行切片處理，導入 3D 打印機，層層堆疊打印成型，打印完成后進行打磨、拋光等后處理，去除表面瑕疵。組裝階段，遵循從內到外、由下至上順序，先安裝機器人內部框架結構，再逐步安裝動力系統（若有簡單動作模擬需求）、電子設備安裝支架等，最后安裝外殼部件，使用螺絲、卡扣等連接件固定，確保各部件緊密配合，整體外觀平整、無縫隙。

　　After the materials are prepared, they enter the processing stage. Metal materials are precisely cut into the desired shape based on design drawings using laser cutting equipment; The bending machine bends thin plates and shapes the curvature of the robot shell; The welding process securely connects various metal components to ensure structural strength. For 3D printed components, it is necessary to slice the model in advance, import it into a 3D printer, stack and print it layer by layer, and after printing, perform post-processing such as grinding and polishing to remove surface defects. During the assembly phase, follow the order from inside to outside and from bottom to top. First, install the internal framework structure of the robot, then gradually install the power system (if there is a need for simple motion simulation), electronic device installation brackets, etc. Finally, install the shell components and fix them with screws, buckles, and other connectors to ensure that each component fits tightly and the overall appearance is smooth and seamless.‘

　　AI 對話功能的巧妙融入

　　Clever integration of AI dialogue function

　　自然語言處理技術基石

　　The cornerstone of natural language processing technology

　　實現 AI 對話核心在于自然語言處理（NLP）技術。該技術賦予機器人理解人類語言、分析語義并生成回復能力。NLP 包含多個關鍵環節，首先是語音識別，通過麥克風采集人類語音信號，轉化為計算機可處理的數字信號，利用深度學習算法（如基于 Transformer 架構的模型）對大量語音數據進行訓練，識別出語音中的文字內容。接著是自然語言理解，對識別出的文字進行詞法、句法、語義分析，理解用戶提問意圖。例如，當用戶問 “機器人，你能介紹下自己嗎”，系統通過分析，明確用戶想獲取機器人相關信息這一意圖。最后是自然語言生成，根據理解的意圖，從預先構建的知識庫或通過模型推理，生成合適回復語句，并轉化為語音播放給用戶。

　　The core of implementing AI dialogue lies in natural language processing (NLP) technology. This technology endows robots with the ability to understand human language, analyze semantics, and generate responses. NLP involves multiple key steps, the first of which is speech recognition. Human speech signals are collected through microphones and converted into digital signals that can be processed by computers. Deep learning algorithms (such as models based on Transformer architecture) are used to train a large amount of speech data and recognize the textual content in the speech. Next is natural language understanding, which performs lexical, syntactic, and semantic analysis on the recognized text to understand the user's questioning intention. For example, when a user asks "Robot, can you introduce yourself?", the system analyzes and clarifies the user's intention to obtain information about the robot. Finally, there is natural language generation, which generates appropriate response sentences based on the intended understanding from a pre built knowledge base or through model inference, and converts them into speech for playback to the user.

　　對話系統搭建要點

　　Key points for building a dialogue system

　　搭建 AI 對話系統需選擇合適框架與工具。常見開源框架如 Rasa、Dialogflow 等，提供便捷開發接口與豐富功能模塊。開發人員基于這些框架，根據機器人應用場景與功能需求，構建對話流程與邏輯。比如在科技館機器人模型中，針對科普知識問答場景，創建不同主題對話分支，如天文知識、物理原理等，每個分支下設置多個問題及對應答案。同時，引入知識圖譜技術，將各類知識以結構化形式存儲，便于機器人快速檢索相關信息，提高回答準確性與豐富度。為提升對話流暢性與智能性，還需對對話系統進行大量數據訓練與優化，使用真實對話數據對模型進行微調，使其更好適應實際應用場景。

　　To build an AI dialogue system, it is necessary to choose appropriate frameworks and tools. Common open-source frameworks such as Rasa and Dialogflow provide convenient development interfaces and rich functional modules. Based on these frameworks, developers construct dialogue processes and logic according to robot application scenarios and functional requirements. For example, in the robot model of a science museum, different topic dialogue branches are created for popular science knowledge Q&A scenarios, such as astronomy knowledge, physics principles, etc. Multiple questions and corresponding answers are set under each branch. At the same time, knowledge graph technology is introduced to store various types of knowledge in a structured form, making it easier for robots to quickly retrieve relevant information and improve the accuracy and richness of answers. To improve the fluency and intelligence of dialogue, it is necessary to conduct extensive data training and optimization of the dialogue system, and use real dialogue data to fine tune the model to better adapt to practical application scenarios.

　　硬件集成與調試收尾

　　Hardware integration and debugging completion

　　將 AI 對話功能集成到大型機器人模型硬件中時，需選用合適硬件設備。核心處理器負責運行對話系統軟件，要求具備一定計算能力與內存容量，可選用工業級嵌入式計算機或小型服務器。語音輸入輸出設備同樣關鍵，高靈敏度麥克風確保清晰采集語音，優質揚聲器保證語音播放清晰、洪亮。通過數據接口（如 USB、串口等）將處理器與麥克風、揚聲器連接，并進行硬件驅動安裝與配置。完成硬件集成后，進行全面調試。測試語音識別準確率、語義理解正確性、回復生成合理性以及語音播放效果等，對發現的問題及時調整優化，如調整麥克風位置改善語音采集效果，優化對話系統參數提高識別與理解準確率，確保 AI 對話功能在大型機器人模型中穩定、高效運行，為用戶帶來流暢、智能交互體驗。

　　When integrating AI dialogue functionality into the hardware of large robot models, appropriate hardware devices need to be selected. The core processor is responsible for running the dialogue system software and requires a certain amount of computing power and memory capacity. Industrial grade embedded computers or small servers can be selected. Voice input and output devices are equally critical, with high-sensitivity microphones ensuring clear voice capture and high-quality speakers ensuring clear and loud voice playback. Connect the processor to the microphone and speaker through data interfaces such as USB and serial ports, and install and configure hardware drivers. After completing hardware integration, conduct comprehensive debugging. Test the accuracy of speech recognition, semantic understanding, rationality of reply generation, and speech playback effect, and adjust and optimize any problems found in a timely manner, such as adjusting the microphone position to improve speech collection effect, optimizing dialogue system parameters to improve recognition and understanding accuracy, ensuring stable and efficient operation of AI dialogue function in large robot models, and bringing smooth and intelligent interaction experience to users.
