RobotEra XHAND1 | 12-DOF Dexterous Robotic Hand with Tactile Sensing

RobotEra XHAND1 – 12-DOF Dexterous Robotic Hand with 3D Tactile Sensing

The RobotEra XHAND1 is an advanced dexterous robotic hand designed for humanoid robotics, embodied AI, robotic manipulation, teleoperation, research, and intelligent automation applications.

Engineered with 12 active degrees of freedom (DoF) and a fully direct-drive architecture, XHAND1 combines high-precision motion control with sophisticated tactile perception to enable responsive, human-like manipulation.

Five fingertip tactile sensor arrays provide 270° three-dimensional tactile sensing, allowing robotic systems to perceive interaction forces while performing grasping and manipulation tasks.

Advanced Dexterous Manipulation

XHAND1 provides 12 actively controlled degrees of freedom distributed across the five fingers.

The thumb incorporates three active joints, while the index and middle fingers each provide three active degrees of freedom. The ring and little fingers each provide additional active articulation.

This architecture enables the hand to perform complex grasping and manipulation tasks while maintaining a compact form factor comparable to an adult human hand.

270° 3D Tactile Sensing

Each fingertip incorporates a high-density 270° three-dimensional surround tactile sensor array.

The tactile system provides three-dimensional force perception, including tangential forces along the X and Y axes, giving robotic control systems valuable physical interaction data during manipulation.

This makes XHAND1 particularly suitable for applications involving AI manipulation training, robotic learning, teleoperation, grasping research, and embodied intelligence.

High Load & Gripping Capability

Despite its compact size, XHAND1 is designed for demanding manipulation tasks.

According to RobotEra's specifications, the hand provides:

• Rated load: 5 kg
• Maximum upward load: 25 kg
• Finger gripping force: 15 N
• Whole-hand gripping force: 80 N

These capabilities allow XHAND1 to combine precision manipulation with substantial gripping performance.

Precision Motion Control

XHAND1 is designed for accurate and repeatable robotic manipulation.

The fingertip repeat positioning accuracy is specified at ±0.20 mm, while the hand supports a repeated opening and closing frequency of greater than 2 Hz.

Its backdrivable design and low backdrive damping of ≤0.1 Nm support responsive physical interaction and advanced robotic control strategies.

High-Speed Communication & Control

For integration with robotics platforms and research systems, XHAND1 supports:

EtherCAT and RS485 (USB) communication interfaces.

The system supports multiple control methods, including:

• Position control
• Low-damping / high-damping modes
• Current-loop force control
• Force-position control

This flexibility makes the hand suitable for integration into humanoid robots, robotic arms, AI research platforms, and custom automation systems.
