Paired with the Wuji Glove teleoperation glove for an end-to-end workflow from data collection to training
About
Human-level dexterity,
for research and development.
Wuji Hand 2 is a five-finger dexterous robotic hand developed by Wuji Technology in Shenzhen, China. All 20 degrees of freedom — four per finger — are directly driven by motors, reproducing full thumb opposition and finger abduction. MIT-style hybrid force-position control enables delicate manipulation such as pinching, twisting and pressing.
As the official distributor in Japan, HumansX supports you in Japanese from product selection and demos to post-installation technical support.
Core Technology
Four core technologies behind its dexterity
Biomimetic skeleton and soft skin
A three-layer structure of skeleton, soft pad and skin. Human-like compliance lets it grasp objects without damaging them.
Direct drive with high force transparency
Serial direct-drive joints with no nonlinear coupling mechanisms. Fully back-drivable, so external forces are sensed accurately.
Fingertips with multi-axis force sensing
Multi-axis force/torque sensors are built into the fingertips, supporting precise pinching and fine work using the fingernails.
Compact yet powerful
About 180 × 80 × 40 mm — close to a human hand — with fingertip peak force of 12 N or more and joint backlash under 1°.
Robustness
Designed for long-term, stable operation
From durability to ease of integration, it minimizes maintenance effort and recovery time after failures, so you can focus on your research and development.
Impact-resistant and durable
A robust structure that withstands contact and impacts during experiments.
Modular, quick assembly
The modular design makes part replacement and maintenance easy.
EtherNet communication
Stable connection to host systems via 100BASE-T (RJ45).
12 V DC power
Ships with a 12 V 20 A power adapter, ready to use out of the box.
Software Ecosystem
Covering the entire workflow, from development to training
Wuji SDK & CLI
Python / C interfaces for device discovery, state reading and command output. Real-time visualization provides one-stop development and debugging.
Native ROS 2 support
Integrates seamlessly into existing robot systems.
MuJoCo / Isaac Sim
High-fidelity simulation models in URDF, MJCF and USD formats for Sim-to-Real training.
Teleoperation
Supports teleoperation from multiple input devices, including the Wuji Glove.

Wuji Glove
A tactile data glove that transfers
human hand motion directly to robots.
A teleoperation glove that fuses a high-density pressure sensor matrix with electromagnetic motion capture. Combined with Wuji Hand 2, it enables a seamless workflow from collecting dexterous manipulation data to training.
- Tactile sensor: 24×31 matrix, 526 points, 120 FPS (4 mm / 0.1 N resolution)
- Electromagnetic tracking: 6 DoF, position accuracy ≤ 2 mm, orientation accuracy < 5°
- 6-axis wrist IMU (800 Hz); motion-to-data latency ≤ 10 ms
- Lightweight glove body of 67.5 g; durability of 100,000+ cycles
- USB Type-C power, RJ45 (100BASE-TX) connection, Python SDK / CLI support
The glove captures human hand motion and touch
Converted to robot hand joints in real time
Wuji Hand 2 reproduces the same motion
Train AI models with the collected data
