7-Axis Humanoid Robotic Arm

As one of the core execution components for embodied intelligence, Huayan’s 7-axis humanoid robotic arms provide an efficient integration solution for quadruped, humanoid, and other embodied robotic platforms. Currently available in the Echo and HY series, the lineup includes six models with payload ranging from 3 kg to 15 kg, suitable for a wide range of complex production scenarios.

High-Precision Full-Joint Force Control

Force control accuracy reaches ≤0.02 N·m, with a control bandwidth of ≥100 Hz and end-effector contact force accuracy of 0.1N. It can continuously perceive subtle external forces and achieve millisecond-level compliant response.

Compact Form, Powerful Performance

With a lightweight design, it enables stable operation across various embodied platforms, including quadruped and humanoid robots.

Large Hollow Design

Minimum internal routing diameter of 15mm, supports simultaneous routing of Gigabit Ether/GMSL cables, power cables, and signal cables

More Than a Tool— An Intelligent Partner

Integrated with a local AI server and natively compatible with ROS2, the system features edge decision-making capabilities. It can autonomously detect deviations, identify anomalies, and adjust trajectories in real time

One Controller, Multiple Arms
Ultra-Compact Design

A single controller can operate up to four humanoid robotic arms. Featuring an ultra-compact design, it saves space, simplifies integration, and is better suited for the compact structure of humanoid robots.

Echo Series
Coplanar Cross-Axis Configuration

With a 7-axis design and coplanar cross-axis configuration, the arm delivers human-like flexibility, smooth obstacle avoidance in confined spaces, and precise execution of delicate, complex tasks.

HY Series
Spatial Cross Configuration

The spatial cross-axis configuration delivers a larger workspace, reduced singularity risk, and higher structural rigidity.
