Core Hardware

We design and build world-class actuators in-house.

We develop every core component in-house, from reducers and mechanisms to electronics, achieving performance that matches or exceeds the humanoid robot actuators of leading makers in the U.S. and China.

KEY FEATURE 01

Self-Developed High-Performance Actuators

The core components of robots deployed on real industrial sites

Diden develops most of the core components of its actuators in-house and assembles them internally. This enables flexible response to customer performance requirements. Through optimization-based design, we precisely select gear ratios to achieve both high performance and a compact structure. We also apply a hollow structure that keeps wires from being exposed externally, enabling reliable and stable operation even in industrial environments with welding dust and sparks.

01

Peak Instantaneous Torque Density of 194 Nm/kg

World-class performance — output that matches or exceeds the humanoid robot actuators of leading makers in the U.S. and China

High payload capacity is essential for carrying heavy equipment on industrial sites. Our actuator achieves a peak instantaneous torque density of 194 Nm/kg, world-class drive performance. *Figures based on specification sheets.

02

Hollow-Shaft Structure

A hollow structure that routes cables internally, maximizing robot design freedom

Cables run through the center bore of the shaft, so designs keep external cabling to a minimum. This reduces the risk of cable damage and breakage on site and makes waterproof, dustproof designs easier to achieve.

03

Diden Actuator

Motor, reducer, driver, and frame designed as one integrated system

The motor, reducer, driver, and frame are designed as one integrated system. Because every core component is our own, packaging, performance, heat dissipation, and wiring are optimized together, and the design adapts flexibly to each customer’s specifications.

04

In-House Design & Assembly Infrastructure

Core components designed and assembled internally

Everything from design and post-machining to assembly and 3D printing happens in-house. This gives customers flexibility and shortens lead times from design change through fabrication and verification.

KEY FEATURE 02

EPM-Based Magnetic Feet

World-leading magnetic-foot design technology that delivers all three: instantaneous switching, air-gap tolerance, and curved-surface adaptation

Our magnetic-foot technology combines polygonal-array (S-EPM) and Halbach-array (H-EPM) electro-permanent magnets with a differential ankle joint.

01

S-EPM Instantaneous Switching

A polygonal magnet arrangement lowers the switching voltage, delivering instantaneous switching and high energy efficiency. This technology achieved the world’s fastest wall-climbing speed.

02

High Durability, Verified Reliability

We built our own test rigs to verify adhesion force and repeated-adhesion performance. On/off cycling tests confirmed a maximum adhesion force of 2,250 N.

03

H-EPM Air-Gap Adhesion

A Halbach array built into the electro-permanent magnets improves adhesion across air gaps, raising adhesion force by 83% at a 0.5 mm gap and ensuring stable walking on painted surfaces.

04

Differential Ankle Joint

Our differential ankle joint lets small electro-permanent magnets conform to the surface as they grip, maintaining stable contact even on curved and stepped terrain.
