Dexrobot 021PRO Wrist-Hand Integrated Dexterous Hand (021PRO)

Dexrobot 021PRO Wrist-Hand Integrated Dexterous Hand (021PRO)

The platform is positioned as a research-grade end-effector that combines high joint dexterity, tendon-driven actuation, and dense multi-modal sensing to support fine manipulation in both structured and unstructured settings.

Unlike many robotic hands that emphasize degrees of freedom (DOF) alone, DexRobot’s published materials frame the 021PRO around measurable dexterity, coupling mechanical kinematics with sensing, control, and onboard compute intended to close the loop from perception to action.

Design and Features

Wrist-hand integrated architecture

A defining characteristic of the 021PRO is its wrist-hand integrated structure, intended to expand reachable orientations and improve coordinated manipulation compared with hands that mount on a simpler wrist or fixed flange. DexRobot describes this as an “extended wrist DOF and coordination” approach that supports broader, more humanlike object reorientation and in-hand manipulation.

22-DOF bionic structure and opposition capability

Manufacturer/press materials describe the 021PRO as featuring 22 joint DOFs (with 18 active), aiming for humanlike finger articulation and opposition—an important property for stable grasps, tool use, and precision handling.

Dual-tendon omnidirectional drive

DexRobot highlights a dual-tendon omnidirectional drive system designed to enable opposable movements and 3D spatial coverage, mirroring elements of human tendon routing and allowing complex motions such as coordinated flexion/extension and lateral movement used in fine manipulation.

Global perception design and embedded compute

The 021PRO is marketed as integrating a “global perception” sensing design and embedded local computing/edge compute to support fast closed-loop control, including tactile feedback and perception-driven grasping behaviors.

Technology and Specifications

Reported kinematics and actuation (high-level)

Published information describes:

• 22 joint DOFs (18 active) in a wrist-hand integrated form factor

• Dual-tendon omnidirectional drive for opposable motion and 3D manipulation coverage

DexRobot’s broader DexHand line (including non-PRO variants) has also been discussed in academic literature as cable/tendon-driven designs balancing dexterity with durability and control practicality, reinforcing the plausibility of tendon-based compliance and force-aware control in the product family.

Sensing suite (as described in press materials)

DexRobot’s press materials list a dense, hand-integrated sensing package, including:

• 400+ tactile sensing units

• 20 high-precision joint position sensors

• A 5MP RGB palm camera

• 500+ total physical sensing points feeding hybrid control algorithms

This combination is presented as enabling real-time state capture, tactile-visual perception, and hybrid position/force control, with tendon-driven compliance contributing to stable operation in less structured environments.

Precision, payload, and durability (reported claims)

Public claims in DexRobot’s distributed materials include:

• Sub-millimeter operational precision (described in the context of sensing + hybrid control)

• 50N payload for complex 3D manipulation (as stated in CES-related PR distribution)

• 300,000+ durability test cycles

Because these figures are reported in press/marketing communications, real-world performance typically depends on grasp geometry, duty cycle, control mode, and environmental conditions.

Software and integration

DexRobot states support for open-source resources and developer tooling, including Python/C++ SDKs, URDF models, kinematic libraries, and simulation examples across its ecosystem.
The 021PRO product page also references availability of SDK support and technical support, and positioning for advanced research and mechanics experiments with expanded interfaces (high level).

Applications and Use Cases

Embodied AI and skill learning

A major target use is embodied AI manipulation, where high-resolution tactile signals and joint sensing can improve grasp stability, slip detection, and contact-rich behaviors. The 021PRO is explicitly positioned within a “Perception-Decision-Action” style closed loop spanning sensing, control, and learning workflows.

Humanoid robotics end-effectors

Humanoid and mobile manipulation platforms benefit from hands that can execute both power grasps and precision grasps. Research on related DexHand designs highlights executing a broad set of grasp taxonomies and manipulation tasks, supporting the broader category of humanlike multi-finger manipulation the 021PRO targets.

Industrial and lab automation prototypes

The 021PRO is promoted as bridging lab prototypes and industrial scenarios through durability testing and robust sensing/control, enabling pilots in bin picking variants, component handling, fixture interaction, and tool-like interactions where tactile feedback improves reliability.

Teleoperation and data collection

DexRobot’s ecosystem messaging emphasizes capturing demonstrations and training manipulation policies using complementary tools (e.g., exoskeleton capture systems) alongside dexterous hands, supporting workflows such as imitation learning and teleoperation development.

Advantages / Benefits

High dexterity with dense perception

Combining 22 DOF (18 active) with hundreds of tactile sensing units and a palm camera is intended to support contact-rich manipulation tasks that are difficult with simple grippers or low-DOF hands.

Tendon-driven compliance and hybrid control

Tendon-driven hands can offer inherent compliance, potentially improving tolerance to minor pose errors and contact uncertainty. DexRobot’s materials explicitly connect sensing and tendon-driven compliance to adaptive behavior and stable operation.

Platform and ecosystem orientation

Beyond hardware, DexRobot emphasizes developer assets (SDKs, URDF, simulation examples) and a closed-loop development narrative, aligning the 021PRO with modern robotics workflows that combine mechatronics, data, and learning.
