Four Key Highlights

Accurate Torque Specifications

Output capacity is designed based on real-world operating conditions to meet the high-dynamic movement requirements of humanoid robots, such as running, jumping, and flipping.

Highly Reliable Mounting Structure

An innovative clamp-style connection reduces intermediate components, enhancing structural rigidity and torque transmission efficiency.

Lightweight Structural Design

The mechanical structure features a lightweight design with hollowed-out sections to reduce weight by 15%.

Hollow Design

The hollow planetary module design simplifies robot cabling and facilitates EtherCAT/CAN wiring.


Five Key Advantages

High Torque Density

Achieves higher output capacity through a compact structure, delivering high torque from a small footprint. Combined with specialized weight-reduction design, this comprehensively elevates the upper limit of joint performance.

Compact Structural Design

Meets the size-sensitive requirements of decoupled configurations, reduces joint volume constraints, and enables smoother motion.

Low Temperature Rise

Efficient motor-driver coordination minimizes heat generation, supporting stable, long-term operation.

Biomimetic Structure

Designed to mimic human anatomy, reducing redundant connections and enabling more direct torque transmission.

Plug-and-Play

Supports mainstream communication protocols, reducing debugging time and enabling rapid integration and stable control.


Application Scenarios

Collaborative Robots, Industrial Automation, Machine Tools, Humanoid Robots.
