Wuji Hand 2

A 20-DoF, direct-drive dexterous robotic hand Paired with the Wuji Glove teleoperation glove for an end-to-end workflow from data collection to training

Human-level dexterity, for research and development.

Wuji Hand 2 is a five-finger dexterous robotic hand developed by Wuji Technology. 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.

Four core technologies behind its dexterity

Biomimetic skeleton and soft skinA three-layer structure of skeleton, soft pad and skin. Human-like compliance lets it grasp objects without damaging them.

Direct drive with high force transparencySerial direct-drive joints with no nonlinear coupling mechanisms. Fully back-drivable, so external forces are sensed accurately.

Fingertips with multi-axis force sensingMulti-axis force/torque sensors are built into the fingertips, supporting precise pinching and fine work using the fingernails.

Compact yet powerfulAbout 180 × 80 × 40 mm — close to a human hand — with fingertip peak force of 12 N or more and joint backlash under 1°.

20 DoF for a wide range of hand poses

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 durableA robust structure that withstands contact and impacts during experiments.

Modular, quick assemblyThe modular design makes part replacement and maintenance easy.

EtherNet communicationStable connection to host systems via 100BASE-T (RJ45).

12 V DC powerShips with a 12 V 20 A power adapter, ready to use out of the box.

Covering the entire workflow, from development to training

Wuji SDK & CLIPython / C interfaces for device discovery, state reading and command output. Real-time visualization provides one-stop development and debugging.

Native ROS 2 supportIntegrates seamlessly into existing robot systems.

MuJoCo / Isaac SimHigh-fidelity simulation models in URDF, MJCF and USD formats for Sim-to-Real training.

TeleoperationSupports teleoperation from multiple input devices, including the Wuji Glove.

With a data glove, human hand motion goes directly to robots.

A teleoperation glove that captures fingertip position and orientation precisely with electromagnetic motion capture. Combined with Wuji Hand 2, it covers everything from collecting dexterous manipulation data to training.

6-DoF electromagnetic tracking, position accuracy ≤ 2 mm, orientation accuracy < 5°, 120 Hz output
6-axis wrist IMU (800 Hz); motion-to-data latency ≤ 10 ms
Lightweight fabric design, glove body 67.5 g
USB Type-C power, RJ45 (100BASE-TX) connection, Python SDK / CLI support

Capture human hand motion with the glove

Converted to robot hand joints in real time

Wuji Hand 2 reproduces the same motion

Train AI models with the collected data

Wuji Hand 2 × Wuji Glove Deploy it as a complete dual-arm system.

We also offer the Dual-Arm Data Collection System, combining a force-controlled dual-arm robot with Wuji Hand 2 (left & right), Wuji Glove, VR teleoperation and synchronized recording software. Start collecting bimanual data right after delivery, with no integration work.
