As artificial intelligence technology matures and large-scale models continue to emerge, the ultimate challenge for the global technology industry has become how to truly "ground" AI and give it a physical form. Embodied intelligence, serving as the bridge connecting virtual intelligence with the physical world, is reshaping manufacturing, service industries, and even human lifestyles at an unprecedented pace. In this monumental industrial wave, the robot's "arm," as the core actuation component, is undoubtedly the key determinant of its ability to truly enter the real world.
On April 25th, HUAYAN ROBOTICS (01021), a leader in China's collaborative robot sector, officially launched its highly anticipated series of 7-axis humanoid arm products, building upon its comprehensive capabilities honed from deep involvement in high-end collaborative robotics. This is not merely a product launch but represents a core strategic move by HUAYAN ROBOTICS in the field of embodied intelligence. Acting as the "actuation brain" for embodied intelligence, this product series, with its outstanding performance, broad application capabilities, and fully open ecosystem enablement, signifies HUAYAN ROBOTICS' accelerated transition from a pure equipment manufacturer to a full-stack technology solutions provider for embodied intelligence.
For an embodied agent, perception and interaction capabilities are the first step to integrating into the real world. The most remarkable feature of the newly launched 7-axis humanoid arm from HUAYAN ROBOTICS is its extremely refined perception and response capabilities, a benefit of the company's deep accumulation in full-stack, self-developed hardware-software integration. Regarding core components, HUAYAN ROBOTICS possesses over twenty years of core technological expertise in key areas such as high-performance motors, joint modules, and servo drives. This strategy of controlling underlying technology in-house allows HUAYAN to break through the barriers of traditional component assembly and achieve system-level optimization.
Through self-developed integrated force-control joints and force-control algorithms, HUAYAN has endowed the 7-axis humanoid arm with human-like force sensing and interaction abilities. The arm achieves high-precision force control across all joints, with a force control precision of ≤0.02 N·m, a force control bandwidth of ≥100 Hz, and an end-contact force precision of 0.1 N. This means it can not only perceive minute external forces, such as the fall of two sheets of A4 paper, but also respond compliantly within milliseconds, laying a safe foundation for complex human-robot interaction scenarios.
Alongside acute perception, intelligence is another core characteristic of the HUAYAN 7-axis arm. HUAYAN has pushed decision-making capabilities to the edge, integrating a local AI server and offering native support for ROS2. Developers can directly build a "perception-decision-action" closed loop on the arm itself, transforming it from an execution tool into an intelligent partner capable of autonomously sensing deviations, judging anomalies, and adjusting trajectories in real-time, significantly lowering development barriers and shortening the algorithm verification cycle.
In terms of operational precision and physical design, the HUAYAN 7-axis humanoid arm also demonstrates high engineering standards. Its absolute positioning accuracy is <1 mm, with a repeatability of ±0.03 mm, equivalent to one-third the diameter of a human hair, meeting stringent requirements for precision assembly. Regarding materials and structure, the entire arm utilizes a high-rigidity aluminum alloy hybrid structure and self-developed high-torque-density motors, with a self-weight of ≤12 kg. This lightweight design enables stable operation on various embodied platforms, including quadrupeds and humanoids.
The HUAYAN 7-axis humanoid arm replicates the flexibility and high-speed precision of a human arm, offering two wrist joint designs: the Echo series (co-planar cross-configuration) and the HY series (non-coplanar cross-configuration). These enable natural human-arm-like movements such as obstacle avoidance, circumvention, and elbow bending, allowing for effortless operation in confined spaces. Furthermore, the product pioneers an "end-effector cabling revolution," featuring a large hollow channel with a minimum pass-through diameter of 15 mm. This allows simultaneous routing of Gigabit Ethernet/GMSL cables, power cables, and signal cables, eliminating tangling and interference and enabling plug-and-play functionality for end-effectors like dexterous hands and vision modules.
Additionally, the arm is easy to deploy, with a single controller capable of managing up to four arms, facilitating space-saving and efficient multi-arm coordination. Operating noise at full load and speed is ≤50 dB, quieter than normal conversation, making it highly suitable for low-noise environments like laboratories and hospitals.
To address the diverse needs of different industries and scenarios, HUAYAN ROBOTICS simultaneously unveiled a rich, serialized product matrix at the launch event, covering the full spectrum from precision manipulation to heavy-duty handling. The Echo series, with its co-planar cross-configuration, offers greater flexibility and excels at intricate, complex tasks. The HY series, featuring a non-coplanar cross-configuration, has fewer singularities and offers higher structural stiffness and precision. Both series include three models with different payload capacities, forming a clearly tiered product line.
Among them, the Echo 3 and HY 3 excel in precision, force control, lightweight design, and low noise, with rated payloads of 3 kg and 3.5 kg respectively. These models can be easily deployed on desktops or mobile robots, breaking the stereotype of "bulky" arms on embodied platforms and enabling robots to truly enter laboratories, commercial services, and potentially future home scenarios.
The Echo 5 and HY 7 both achieve a repeatability of ±0.03 mm, with rated payloads of 5 kg and 7 kg respectively. This range meets the rigid demands of mainstream manufacturing scenarios like 3C electronics screw fastening and automotive parts assembly, effectively addressing core pain points in industrial manufacturing.
The Echo 15 and HY 15 both boast a rated payload of 15 kg, making them capable of handling heavy-duty tasks such as machine tending, large-part assembly, and even palletizing, representing high-payload embodied intelligent arms truly suited for most factories and production lines.
It is reported that the HUAYAN Echo and HY series 7-axis humanoid arms are officially available for pre-order starting immediately.
Beyond technical barriers and product matrices, HUAYAN ROBOTICS possesses a profound understanding of industry trends. The company recognizes that the explosion of embodied intelligence is not a solo act by any single enterprise but depends on the creativity and vibrancy of the entire developer ecosystem. Therefore, from its very first 7-axis humanoid arm, HUAYAN has firmly chosen a path of comprehensive openness.
At the interface and protocol level, the HUAYAN 7-axis arm offers broad compatibility with various software/hardware systems, upstream/downstream platforms, and data acquisition interfaces through SDKs, native ROS2 drivers, and standard open protocols including Modbus TCP and EtherNet/IP. More notably, HUAYAN has achieved comprehensive openness, from kinematic solutions and trajectory planning to force control interfaces and visual calibration, even allowing developers to directly modify underlying impedance control parameters. This deeply open approach empowers developers to quickly access advanced functions and perform deep secondary development, returning the power of creation to the ecosystem—an invaluable contribution to accelerating the proliferation of embodied AI application scenarios.
Regarding safety and real-time performance, the HUAYAN 7-axis arm strictly adheres to ISO 13849 and ISO 10218 safety standards, ensuring human-robot collaboration safety from the ground up. It utilizes EtherCAT industrial real-time Ethernet, with a control cycle as low as 1 millisecond, providing a solid foundation for real-time decision-making by embodied intelligence in complex, dynamic environments and ensuring the robot can perform instant safety stops or trajectory adjustments in unexpected situations.
Positioned at a crossroads of industrial transformation, this launch by HUAYAN ROBOTICS is not just a product update but a preview of the future evolution path of embodied intelligence. As envisioned by HUAYAN during the launch, today's products may be 7-axis arms, but driven by the accelerated deployment of full-stack embodied AI technology, they are expected to achieve new breakthroughs in mobility, perception, and interaction capabilities by next year.
Moving forward, HUAYAN ROBOTICS will continue to advance the evolution of the 7-axis humanoid arm towards a true embodied agent, further integrating multi-modal perception, autonomous learning, and swarm collaboration capabilities. By collaborating with global partners, the company aims to propel the 7-axis humanoid arm's transition from a mere "execution tool" to a "decision-making partner" with autonomous judgment abilities, ultimately enabling humanoid robots to truly integrate into human production and daily life.
