　　The core password for robot joints: guide screw scheme, unlocking new possibilities for agile movement

　　在機器人技術飛速迭代的今天，關節的靈活性、精準度直接決定機器人的實操能力，而導軌絲杠作為線性執行器的核心部件，正是驅動機器人關節靈活運轉的“幕后功臣”。很多從事機器人研發、采購的從業者都會問：線性執行器有哪些新型導軌絲杠方案？不同方案適配哪些機器人關節？今天，就結合實際應用場景，詳細拆解導軌絲杠在機器人關節中的核心應用方案，徹底解答“機器人關節線性執行器該選哪種導軌絲杠方案”這一核心問題，帶大家讀懂導軌絲杠如何撐起機器人關節革命。

　　In today's rapidly iterating robot technology, the flexibility and accuracy of joints directly determine the practical ability of robots, and the guide screw, as the core component of linear actuators, is the "behind the scenes hero" driving the flexible operation of robot joints. Many practitioners engaged in robot research and procurement will ask: What are the new guide screw solutions for linear actuators? Which robot joints are suitable for different schemes? Today, based on practical application scenarios, we will dissect in detail the core application scheme of guide screws in robot joints, thoroughly answering the core question of "which guide screw scheme should be selected for linear actuators in robot joints", and guiding everyone to understand how guide screws support the revolution of robot joints.

　　導軌絲杠是將旋轉運動轉化為直線運動的核心傳動部件，被譽為機器人關節的“骨骼脈絡”，其性能直接影響機器人關節的精度、負載能力與使用壽命。目前，適配機器人關節的線性執行器，核心導軌絲杠方案主要有兩類，分別對應不同關節部位的使用需求，兼顧靈巧性與穩定性，其中主流的就是反向式行星滾珠絲杠方案。

　　The guide screw is the core transmission component that converts rotational motion into linear motion, and is known as the "skeleton network" of robot joints. Its performance directly affects the accuracy, load capacity, and service life of robot joints. At present, there are mainly two types of core guide screw solutions for linear actuators adapted to robot joints, which correspond to the usage needs of different joint parts and balance agility and stability. Among them, the most mainstream is the reverse planetary ball screw solution.

　　反向式行星滾珠絲杠，是機器人手腳關節的“專屬適配方案”，也是目前線性執行器中應用廣泛的導軌絲杠類型。它融合了行星減速器和絲杠的核心原理，通過滾珠作為傳動介質，將滑動摩擦轉化為滾動摩擦，傳動效率高、定位精度準，同時具備結構緊湊、負載能力強的優勢，適配機器人手關節、腳關節的運動需求。機器人手腳關節需要頻繁做伸縮、轉動動作，對精度和靈活性要求極高，反向式行星滾珠絲杠能精準控制關節的微小位移，確保動作流暢連貫，同時承受關節運動產生的負載，避免出現卡頓、偏移等問題，為機器人靈活活動提供穩定支撐。

　　Reverse planetary ball screw is an "exclusive adaptation solution" for robot hand and foot joints, and is currently the most widely used type of guide screw in linear actuators. It combines the core principles of planetary reducer and screw, using ball as the transmission medium to convert sliding friction into rolling friction, with high transmission efficiency and accurate positioning accuracy. At the same time, it has the advantages of compact structure and strong load capacity, perfectly adapting to the motion needs of robot hand joints and foot joints. The joints of the robot's hands and feet require frequent extension, rotation, and high precision and flexibility. The reverse planetary ball screw can accurately control the small displacement of the joints, ensuring smooth and coherent movements while bearing the load generated by joint movements, avoiding problems such as jamming and deviation, and providing stable support for the robot's flexible activities.

　　除了手腳關節，機器人手腕部位的靈巧運動，離不開另一類核心方案——反向式滾珠絲板。手腕關節相較于手腳關節，動作更精細、空間更緊湊，對導軌絲杠的體積、精度要求更為嚴苛，而反向式滾珠絲板恰好契合這一需求。它的結構更為精巧，能在狹小空間內實現精準傳動，適配手腕關節的靈活轉動與微調，讓機器人手腕能夠完成抓取、翻轉等精細動作，大幅提升機器人的實操能力。目前，這類滾珠絲板已實現小型化突破，小可做到040.5規格，專門適配靈巧手等對體積、精度有要求的機器人部件，真正實現了“小身材，大作用”。

　　In addition to the joints of the hands and feet, the agile movement of the robot wrist cannot be separated from another core solution - the reverse ball screw plate. Compared to the joints of the hands and feet, the wrist joint has finer movements and more compact space, requiring more stringent requirements for the volume and accuracy of the guide screw. The reverse ball screw plate perfectly meets this requirement. Its structure is more sophisticated, enabling precise transmission in small spaces and adapting to flexible rotation and fine-tuning of wrist joints, allowing the robot wrist to perform fine actions such as grasping and flipping, greatly improving the robot's practical ability. At present, this type of ball screw plate has achieved a breakthrough in miniaturization, with a minimum specification of 040.5, specially adapted for robot components such as dexterous hands that have extreme requirements for volume and accuracy, truly realizing the concept of "small body, big function".

　　可能有人會疑惑，同樣是導軌絲杠方案，反向式行星滾珠絲杠與反向式滾珠絲板有何核心區別？其實關鍵在于適配場景的差異：前者側重負載能力與靈活傳動，適配機器人手腳關節這類需要承受一定負載、動作幅度較大的部位；后者側重小型化與精細傳動，適配手腕、靈巧手這類動作精細、空間有限的部位，兩者分工明確，共同支撐機器人關節的運轉。

　　Some people may wonder, what is the core difference between reverse planetary ball screw and reverse ball screw plate for the same guide screw scheme? In fact, the key lies in the differences in adaptation scenarios: the former focuses on load capacity and flexible transmission, adapting to parts such as robot hand and foot joints that require a certain load and a large range of motion; The latter focuses on miniaturization and fine transmission, adapting to parts with fine movements and limited space such as wrists and dexterous hands. The two have clear division of labor and jointly support the comprehensive operation of robot joints.

　　作為機器人關節線性執行器的核心，這兩類導軌絲杠方案的突破，徹底推動了機器人關節的“革命”。相較于傳統導軌絲杠，反向式行星滾珠絲杠和反向式滾珠絲板，在精度、體積、負載能力上均有顯著提升，尤其是040.5規格滾珠絲板的研發，打破了小型化導軌絲杠的技術瓶頸，讓靈巧手等高精度機器人部件的研發成為可能，也讓機器人能夠適配更多精細操作場景。

　　As the core of linear actuators for robot joints, the breakthrough of these two types of guide screw schemes has thoroughly promoted the "revolution" of robot joints. Compared to traditional guide screws, reverse planetary ball screws and reverse ball screw plates have significantly improved accuracy, volume, and load capacity. Especially with the development of 040.5 specification ball screw plates, the technological bottleneck of miniaturized guide screws has been broken, making it possible to develop high-precision robot components such as dexterous hands, and enabling robots to adapt to more precise operation scenarios.

　　從行業應用來看，導軌絲杠方案的選擇，核心是匹配機器人關節的使用需求。手腳關節優先選擇反向式行星滾珠絲杠，兼顧負載與靈活；手腕、靈巧手等精細部位，優先選擇小型化反向式滾珠絲板，追求精度與小巧。無論是工業機器人的重載關節，還是服務機器人的靈巧關節，導軌絲杠的適配性都直接決定機器人的性能上限，這也是為什么說導軌絲杠是機器人關節革命的核心支撐。

　　From the perspective of industry applications, the core of selecting a guide screw solution is to match the usage needs of robot joints. Prioritize the use of reverse planetary ball screws for hand and foot joints, balancing load and flexibility; For delicate parts such as wrists and dexterous hands, priority is given to small-sized reverse ball screw plates, pursuing precision and compactness. Whether it is the heavy-duty joints of industrial robots or the agile joints of service robots, the adaptability of guide screws directly determines the performance limit of robots, which is why guide screws are the core support of the robot joint revolution.

　　很多人在選擇機器人線性執行器時，容易陷入“精度越高越好”的誤區，其實不然，導軌絲杠方案的選擇，關鍵是“適配”。不同機器人關節的運動需求、負載大小、空間限制各不相同，只有結合關節部位的實際需求，選擇對應的導軌絲杠方案，才能讓機器人關節發揮性能，既保證動作精準流暢，又延長設備使用壽命。

　　Many people tend to fall into the misconception of "higher accuracy is better" when choosing linear actuators for robots. In fact, the key to choosing a guide screw solution is "adaptation". The motion requirements, load sizes, and space limitations of different robot joints vary. Only by selecting the corresponding guide screw scheme based on the actual needs of the joint parts can the robot joints perform at their best, ensuring precise and smooth movements while extending the service life of the equipment.

　　總而言之，導軌絲杠作為機器人關節的核心傳動部件，其方案的創新的直接推動了機器人關節的升級迭代。反向式行星滾珠絲杠適配手腳關節，反向式滾珠絲板適配精細部位，兩類方案相輔相成，解鎖了機器人靈巧運動的新可能。了解不同導軌絲杠方案的適配場景，才能精準選擇線性執行器方案，為機器人關節賦能，讓機器人在各類場景中發揮更大價值，真正實現機器人關節的技術突破與升級。

　　In summary, as the core transmission component of robot joints, the innovative design of the guide screw directly promotes the upgrading and iteration of robot joints. The reverse planetary ball screw is adapted to the joints of hands and feet, and the reverse ball screw plate is adapted to fine parts. The two schemes complement each other, unlocking new possibilities for the agile movement of robots. Only by understanding the adaptation scenarios of different guide screw schemes can we accurately select linear actuator schemes, empower robot joints, and enable robots to exert greater value in various scenarios, truly achieving technological breakthroughs and upgrades in robot joints.
