Shadow Dexterous Hand

Overview

The Shadow Robot Shadow Dexterous Hand is the benchmark 24-DoF electric dexterous hand from London-based Shadow Robot Company, used in leading robotics research laboratories worldwide for over two decades. It is the most anatomically faithful robot hand commercially available, with kinematic architecture that closely mirrors the human hand including an opposable thumb, four fingers, and a palm that enables complex in-hand manipulation. The Shadow Dexterous Hand is used by NASA, DARPA-funded research programmes, and major university robotics departments as the reference platform for dexterous manipulation research.

Key Specifications

• Degrees of freedom: 24 (20 active, 4 passive)
• Actuation: Electric (tendon-driven via motor box)
• Sensors: Position, force, and optional tactile arrays (BioTac, custom)
• Interface: ROS compatible (strong community support)
• Manufacturer: Shadow Robot Company, London, UK

The tendon-driven actuation system, with motors housed in a separate forearm unit, allows the hand's finger geometry to remain anthropomorphic without the weight penalty of housing motors at each joint. The extensibility of the sensing suite, including optional BioTac tactile fingertips and PST pressure sensors, makes the platform adaptable to a wide range of research questions.

Use Cases

Research applications include in-hand object re-orientation, grasp planning and execution, tactile-driven manipulation, medical and surgical robotics research, and human-robot interaction studies where anthropomorphic hand form is important for natural interaction. UK research groups at institutions including Imperial College London, King's College London, and the University of Edinburgh use the Shadow Dexterous Hand as a core research asset.

The long production history and large user community mean that a wealth of pre-existing code, datasets, and research results reference the Shadow Dexterous Hand, making new research built on this platform more comparable and reproducible.

Buying Used

A secondary market exists, primarily through research institution transitions and the occasional laboratory closure. Shadow Robot Company operates a refurbishment and upgrade service, which can bring older units to current specification. Actuator bundle health, tendon integrity, and sensor calibration are critical checks on any used unit. As a London-based manufacturer, Shadow Robot Company is well positioned to support UK buyers directly.

Alternatives to Consider

• Shadow DEX-EE for a higher-speed version optimised for AI training data collection
• Allegro Hand V5 for a lower-cost 16-DoF research hand with large open-source community
• Wonik Allegro V5 Sense for tactile-enhanced research capability at lower cost than the Shadow
