Physical AI Solution — Dual-Arm Data Collection
With Wuji Hand 2 & Wuji GloveDual-Arm Data Collection System
Wuji Hand 2 and Wuji Glove on a force-controlled dual-arm robot.
Start collecting bimanual data the day it arrives.
Two Roles
One system, two roles.
Collect real-robot data
as it happens.
- Reproduce skilled hand and arm motions on the real robot
- Record arms, hands and 5 cameras on a synchronized timeline
- Export to LeRobot / HDF5 and start training right away
Validate and deploy
trained models on the real robot.
- Evaluate trained models directly on the real robot (Sim2Real)
- Run models on the robot with onboard Jetson
- Trial operation in real environments, from lab to field
Collect → train → validate on the same system, for a faster improvement cycle.

Teleoperation
Put on VR,
and move both arms as you are.
Watch the robot’s head-camera view in VR and simply move your hands and arms. Skilled motions are sent to the robot in real time and recorded directly as training data.
* Image for illustration. The standard configuration uses Wuji Glove for finger input and Wuji Hand 2 as end effectors.

FAQ
Dual-Arm Data Collection System — FAQ
What is the Dual-Arm Data Collection System?
It combines a force-controlled dual-arm robot with Wuji Hand 2 (left & right) and Wuji Glove, covering everything from collecting teleoperated demonstration data to exporting training data. HumansX configures and tunes the system and delivers it ready for data collection on arrival.
How is it different from buying Wuji Hand 2 alone?
With Wuji Hand 2 alone, you need to prepare and integrate the arms, teleoperation environment and data recording yourself. With this system, HumansX provides and tunes all of it as one package, so you can start research without integration work.
What formats can the collected data be exported in?
Arm, hand and camera data are recorded in sync and can be exported as HDF5, ROS bag or LeRobot format, ready for imitation learning and VLA model training.
Can I buy the robot arm alone?
This system is offered as a complete package including Wuji Hand 2, Wuji Glove and data collection software. Please contact us about customizing the configuration.
Can we develop or modify the software ourselves?
Yes. We provide the arm control SDK (Python / C++), the Wuji Hand 2 SDK and retargeting, and URDF / STEP data, so you can use it as a base for developing your own algorithms and applications. HumansX also answers technical questions during development in Japanese.
Please tell me about pricing, lead time and demos.
Pricing depends on the configuration; please contact us via our inquiry form. Lead time is approx. 10–12 weeks after order. We also welcome demo requests.
