Introducing the OmniHand 3 Ultra Robotic Hand
Chinese startup Agilink has unveiled the OmniHand 3 Ultra, a robotic hand engineered to handle the intricate work of fine silk threads with remarkable precision. Developed under the guidance of Fu Xianghong, a master artisan with expertise in Suzhou embroidery traditions spanning over 2,500 years, this cutting-edge device combines heritage craftsmanship with modern robotics. The OmniHand 3 Ultra is equipped with optical sensors on its fingertips, enabling accuracy down to 0.08 millimeters.
Weighing just 630 grams, the robotic hand features a palm surface embedded with a contact sensor encompassing 300 points. This sophisticated design allows the device not only to manipulate silk threads delicately but also to separate them into sixteen individual fibers—a critical step in the Suzhou embroidery process.
Advancements and Comparisons in Robotic Manipulation
In the broader field of robotics, LinkerBot recently showcased a five-fingered robotic hand with flexible tendon cables at a Hong Kong exhibition, demonstrating its capabilities by playing drums and piano. However, this model is considerably heavier than the OmniHand 3 Ultra and offers limited gripping strength, raising questions about its suitability for highly precise tasks.
Meanwhile, Boston Dynamics has experimented with simplifying the hand design of their Atlas robot by removing the pinky finger. Technical Director Zak Yakowski even had team members wrap their pinky and ring fingers for a day to assess their necessity, highlighting ongoing efforts to optimize robotic dexterity.

The development of devices like Agilink’s OmniHand 3 Ultra marks a significant step in bridging ancient artisanal techniques with contemporary technology. It opens new possibilities for traditional crafts such as embroidery, offering unprecedented precision and control.
By integrating innovations like the OmniHand 3 Ultra, traditional craftsmanship can evolve, enabling artisans to master complex techniques with enhanced accuracy. This fusion encourages experimentation with new artistic forms and technologies, potentially transforming the cultural landscape of embroidery and expanding creative horizons.
As the field of robotics continues to evolve, innovations like Agilink's OmniHand 3 Ultra are part of a broader trend. For instance, Boston Dynamics recently introduced a four-fingered hand for its Atlas robot, showcasing advancements in dexterity and articulation that complement the capabilities of devices like the OmniHand. This ongoing development emphasizes the growing intersection of technology and traditional craftsmanship.
