HUAYAN ROBOTICS (01021) launches a seven-axis humanoid arm, opening the door to intelligent industrialization.

Today, as artificial intelligence technology matures and large model capabilities continue to emerge, how to truly "land" AI and give it physical form has become the ultimate proposition of the global technology industry. Embodied intelligence, as a bridge connecting virtual intelligence and the physical world, is reshaping the manufacturing industry, service industry, and even human lifestyle at an unprecedented speed. In this vast wave of industrial change, the core operational component - the "arm" of Siasun Robot & Automation, undoubtedly plays a key role in determining whether it can truly enter the real world. It was learned that on April 25th, HUAYAN ROBOTICS (01021), the leader in the field of collaborative robotics in China, officially released its highly anticipated series of seven-axis humanoid arm products, based on its comprehensive capabilities in the field of high-end collaborative robotics. This is not just the debut of a new product, but also the core strategic layout of HUAYAN ROBOTICS in the field of embodied intelligence. As the "executive brain" of embodied intelligence, this series of products, with outstanding performance, wide application capabilities, and fully open ecological enabling posture, marks HUAYAN ROBOTICS' acceleration from a single device manufacturer to a provider of full-stack embodied intelligence technology solutions. Comparable to the delicacy of a "human arm" For embodied intelligence, the ability to perceive and interact is the first step in integrating into the real world. The most eye-catching feature of the seven-axis humanoid arm introduced by HUAYAN ROBOTICS this time is its extremely delicate perception and reaction capabilities, thanks to the deep accumulation of HUAYAN ROBOTICS in the field of integrated software and hardware development. In terms of core components, HUAYAN ROBOTICS has over twenty years of core technological accumulation in key areas such as high-performance motors, joint modules, servo drives, and other critical components. This strategic control of underlying technology allows HUAYAN to break down traditional barriers to component integration and achieve system-level optimization. By integrating self-developed integrated force-controlled joints and force-controlled algorithms, HUAYAN has endowed the seven-axis humanoid arm with human-like force feedback and interaction capabilities. It is understood that the arm achieves high-precision force control at all joints, with a force control accuracy of 0.02Nm, a force control bandwidth of 100Hz, and an end-effector contact force accuracy of 0.1N. This means that it can not only perceive tiny external forces like two A4 paper floating, but also respond smoothly in milliseconds, laying a safe foundation for complex human-machine interaction scenarios. While achieving acute perception, intelligence is another core aspect of the HUAYAN seven-axis humanoid arm. HUAYAN has decentralized decision-making to the edge, integrated local AI servers, and natively supports ROS2. Developers can directly build a "perception-decision-execution" closed-loop on the arm, transforming it from an execution tool into an intelligent partner capable of autonomously perceiving deviations, judging anomalies, and adjusting trajectories in real time. This significantly reduces the threshold for development and shortens the algorithm verification cycle. In terms of operating precision and physical architecture design, the HUAYAN seven-axis humanoid arm also demonstrates high engineering standards. With absolute positioning accuracy of <1mm and repeatability positioning accuracy of 0.03mm, equivalent to one-third of the diameter of a human hair, it meets the stringent requirements of precision assembly. In terms of materials and structure, the entire arm adopts a high-rigidity aluminum alloy hybrid structure and self-developed high-torque density motors, with a weight of 12KG. The lightweight design allows it to operate stably on various embodied platforms such as quadrupeds and humanoids. It is also noted that the HUAYAN seven-axis humanoid arm replicates the flexibility and high-speed precision capabilities of a "human arm," introducing two wrist joint designs, the Echo series (co-planar cross configuration) and the HY series (non-coplanar cross configuration). These designs enable natural movements such as obstacle avoidance, bypassing, and arm bending in confined spaces. Additionally, the product leads a "end-of-arm wiring revolution," with a large hollow channel with a minimum passing diameter of 15mm, capable of simultaneously passing Gigabit Ethernet cables/GMSL cables+power lines+signal lines, eliminating entanglement interference and enabling plug-and-play functionalities such as dexterous hands and visual modules at the end effector. Furthermore, the arm is easy to deploy, with one controller capable of controlling up to four arms, saving space and effort in multi-arm coordination; the noise level when fully loaded and running at full speed is 50dB, lower than normal conversation volume, making it highly suitable for environments like laboratories and hospitals with low noise requirements. Ecosystem layout covering all scenarios Addressing the differentiated needs of various industries and scenarios, HUAYAN ROBOTICS simultaneously launched a rich series of product matrices at this event to meet the complete spectrum of tasks from precision operations to heavy-duty handling. The Echo series, with a co-planar cross configuration, is more flexible and adept at fine complex tasks; the HY series, with a non-coplanar cross configuration, has fewer singularities and higher structural rigidity and precision. Each of the two major series includes three seven-axis humanoid arms with different payload capacities, forming a clear product line hierarchy. Among them, the Echo 3 and HY 3 offer precision, force control, lightweight construction, and low noise advantages, with rated payloads of 3kg and 3.5kg respectively. These two products can easily be deployed on desktop or mobile embodied platforms, breaking the traditional image of bulky humanoid arm platforms, enabling them to truly enter laboratory, commercial service, and even future home scenarios. The repeat positioning accuracy of Echo 5 and HY 7 can reach 0.03mm, with rated payloads of 5kg and 7kg, which are ideal for mainstream manufacturing scenarios such as 3C electronics assembly and automotive component manufacturing, effectively covering the core pain points of industrial manufacturing. Meanwhile, Echo 15 and HY 15 have a rated payload of 15kg, sufficient for tasks like machine tool loading and unloading, large assembly, and stacking, making them truly capable of entering most factory and production line environments requiring heavy-duty embodied intelligent arms. It is reported that the HUAYAN Echo series and HY series seven-axis humanoid arms are now available for pre-order. Building a developer ecosystem for embodied intelligence Beyond technological barriers and product matrices, HUAYAN ROBOTICS has a deeper insight into industry trends. HUAYAN recognizes that the explosion of embodied intelligence is not the sole work of a single company, but depends on the creativity and prosperity of the entire developer ecosystem. Therefore, starting from the first seven-axis humanoid arm, HUAYAN has firmly chosen a fully open strategic route. At the interface and protocol level, the seven-axis humanoid arm from HUAYAN can be widely compatible with a variety of software and hardware systems, upstream and downstream platforms, and data acquisition interfaces through SDKs, native ROS2 drivers, and standard open protocols including Modbus TCP and EtherNet/IP. Worth mentioning is that, from kinematics solving, trajectory planning, force control interfaces to visual calibration, HUAYAN has achieved comprehensive openness, even allowing developers to directly modify the underlying impedance control parameters. This deep level of openness empowers developers with the ability to quickly access advanced functions and conduct in-depth secondary development, returning the creative power to the ecosystem, which is invaluable for accelerating the proliferation of embodied intelligence applications. In terms of safety and real-time performance, the HUAYAN seven-axis humanoid arm strictly follows ISO 13849 and ISO 10218 safety standards, ensuring the safety of human-robot collaboration from the ground up in design. It also uses EtherCAT industrial real-time Ethernet with control cycle as low as 1 millisecond, providing a solid foundation for real-time decision-making of embodied intelligence in complex dynamic environments, ensuring that Siasun Robot & Automation is able to instantly stop or adjust trajectories in the face of sudden situations. Looking ahead at the crossroads of industrial transformation, HUAYAN ROBOTICS' release is not just a product launch, but also a prelude to the future evolution path of embodied intelligence. As envisioned by HUAYAN at the release event, today they may still be seven-axis arms, but with the accelerated deployment of full-stack embodied intelligence technology, they are expected to achieve new breakthroughs in mobility, perception, and interaction capabilities next year. In the future, HUAYAN ROBOTICS will continue to drive the evolution of the seven-axis humanoid arm towards a true embodied intelligence entity, further integrating multimodal perception, autonomous learning, and group collaboration capabilities, collaborating with global partners to advance the transition of the seven-axis humanoid arm from a mere "execution tool" to a "decision partner" with autonomous judgment, allowing humanoid Siasun Robot & Automation to truly integrate into human production and life.
