Huayan Robotics has introduced six new humanoid robotic arms with precision control capabilities comparable to the weight of “two A4 papers.” On April 25, Huayan Robotics held a launch event for its humanoid arms, unveiling two major series, HY and ECHO, consisting of six seven-axis intelligent arms. The new products emphasize high-precision force control, lightweight design, and an open ecosystem, providing flexible options for industrial and collaborative scenarios.
Specifically, the HY series features a cross configuration with three models: HY3, HY7, and HY15, designed to handle payloads ranging from 3.5 kg to 15 kg. In contrast, the ECHO series employs a coplanar cross configuration, closely mimicking human biomechanics, and includes the ECHO3, ECHO5, and ECHO15 models. All products in both series share advancements in force control performance, hollow wiring, lightweight structure, and open software architecture.
In terms of force control and positioning performance, Huayan has set several high standards for these arms. The torque resolution for the joints reaches 0.02 Nm, with a force control bandwidth of no less than 100 Hz, and an end contact force precision of 0.1 N, equivalent to the gentle placement of two A4 papers in hand. For positioning, the absolute positioning accuracy of the arms is less than 1 mm, while the repeat positioning accuracy can reach as high as ±0.03 mm, showcasing exceptional motion consistency.
To address common issues related to cable entanglement during integration, each arm is designed with a 15 mm hollow channel that can accommodate cables such as gigabit Ethernet and GMSL. The total weight of the arm is kept under 12 kg, and operational noise levels are optimized for environments sensitive to sound.
In terms of software and ecosystem, the system complies with safety standards 13849 and 10218, offering an SDK and ROS2 drivers, facilitating rapid integration with devices like PLCs, industrial computers, and AI boxes. Furthermore, a single controller can simultaneously drive up to four arms, with control cycles as low as 1 millisecond based on EtherCAT bus technology, thereby enhancing multi-machine collaboration and real-time control capabilities.
