Product Overview

The Unitree DEX 2/5 Dexterous Hand is a lightweight, tendon-driven articulated hand designed specifically for humanoid robot applications. Featuring 2 degrees of freedom distributed across 10 joints (8 joints in four fingers, 2 joints in thumb), it provides efficient manipulation capabilities while maintaining minimal weight.

Weighing only 0.80 lb (365g), the DEX 2/5 utilizes tendon-drive actuation for smooth, natural finger movements. The hand operates on a wide 24-58V voltage range and delivers 10N fingertip force for secure object manipulation. Designed as an in-house development by Unitree, it supports secondary development with a provided robot development interface.

Tendon-Drive Actuation

Cable-driven mechanism provides smooth, natural finger movements with reduced weight and complexity compared to direct-drive systems.

Ultra-Lightweight Design

At only 0.80 lb (365g), minimizes arm payload requirements while maintaining functional manipulation capabilities.

10-Joint Architecture

Four fingers with 8 joints plus thumb with 2 joints provide versatile grasping patterns for various object shapes.

Development Support

Full secondary development support with robot development interface provided for custom integration and control.

Design & Architecture

Engineered for efficient manipulation with minimal complexity:

Tendon-Drive System

2 Degrees of Freedom: Efficient DOF distribution for essential manipulation tasks.
10 Total Joints: Four fingers with 8 joints, thumb with 2 joints for versatile grasping.
Tendon-Drive Actuation: Cable-driven system reduces weight and complexity while maintaining smooth operation.
Compact Dimensions: 5.9" x 2.6" x 2.8" (151 x 67 x 70 mm) fits standard humanoid robot arm interfaces.

Performance Specifications

Optimized for reliable manipulation tasks:

Key Performance Metrics

Fingertip Force: 10N -- sufficient force for secure grasping of lightweight to medium-weight objects.
Operating Voltage: 24-58V -- wide voltage range compatible with standard humanoid robot power systems.
Weight: 0.80 lb (365g) -- ultra-lightweight design minimizes arm payload and power consumption.
No Haptic Feedback: Position-based control without force sensing for simplified integration.

Development & Integration

Designed for easy integration and customization:

Secondary Development

Full support for custom development with provided robot development interface and documentation.

In-House Development

Designed and manufactured by Unitree for optimal compatibility with G1 and other humanoid platforms.

Wide Voltage Range

24-58V operation compatible with various robot power systems and battery configurations.

Simple Integration

Standardized mounting interface and control protocols for quick deployment.

What's Included

Single hand package for integration:

Hand	DEX 2/5 Dexterous Hand	One tendon-driven dexterous hand with 2 DOF, 10 joints, and 10N fingertip force.
Documentation	Development Interface	Robot development interface and integration documentation for secondary development.
Mounting	Mounting Hardware	Standard mounting interface compatible with Unitree humanoid robot arms.

Important Notes

Single Hand Pricing: The listed price and specifications apply to a SINGLE hand. Typically, two dexterous hands (left and right) are selected for a complete humanoid robot configuration.
No Haptic Feedback: This model does NOT include haptic (force/torque) feedback sensors. Control is position-based.
Secondary Development: Full secondary development support is provided with robot development interface access.
Compatibility: Designed for Unitree humanoid robots (G1 series and compatible platforms).
Tendon-Drive System: Cable-driven actuation requires periodic maintenance and tension adjustment for optimal performance.
Weight Advantage: At 0.80 lb (365g), significantly lighter than many competing dexterous hands, reducing arm payload requirements.

Important: This product is sold as a SINGLE hand. For bimanual manipulation on a humanoid robot, you will need to purchase TWO units (one left hand and one right hand configuration).
