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

A human hand does not simply grip; it turns, aligns, flips and feels its way through a task, and the wrist is part of every one of those moves. Most robotic hands leave the wrist as someone else's problem. The Dexrobot 021PRO Wrist-Hand Integrated Dexterous Hand (021PRO) takes the opposite view and treats wrist and hand as one machine, with tendon-driven fingers, a dense layer of touch sensing and a camera set into the palm.

Background

The company and its lineage

DexRobot is an embodied intelligent robotics company specializing in dexterous manipulation technology. In plain terms, the company builds robotic hands meant to do the kind of fine work that has long been left to people, and it builds them as a family rather than as a single showpiece.

That family has three named members. The DexHand021 Pro, sold here as the 021PRO, is the newly launched, most capable five-fingered hand. The DexHand021, with 19 degrees of freedom, is the five-fingered hand already in mass production. The DexHand021 S is the three-fingered version for buyers who need a simpler hand; you can read about it on the Dexrobot 021S High-Function Three-Fingered Dexterous Hand page. Each step in the line is aimed at a different kind of need, so it pays to match the hand to the work before you ask for a quotation.

Positioning and key technology

The 021PRO is a highly biomimetic five-fingered dexterous hand. Two ideas define it. The first is the wrist-hand integrated structure, with 22 joint degrees of freedom, 18 of them active, and an actively driven 2-DoF wrist. The second is the dual-tendon omnidirectional drive, which enables opposable movements and 3D spatial coverage and allows flexion, extension and lateral movement to be controlled independently.

Sensing is the third pillar. The hand integrates 400+ tactile sensing units, 20 high-precision joint position sensors and a 5MP RGB palm camera, which together with real-time motor feedback make up more than 500 physical sensing points. That multi-modal data feeds hybrid position/force control algorithms. An integrated edge AI compute module supports millisecond-level tactile feedback and environmental perception, which is what makes autonomous grasping and fine manipulation practical rather than theoretical.

What makes the 021PRO different from a conventional dexterous hand?

The first difference is the wrist. Many robotic hands bolt onto a simple wrist or a separate arm flange, and the fingers do all the work. In the 021PRO the actively driven 2-DoF wrist is part of the same architecture as the fingers, so turning, aligning, flipping and tool use come from natural wrist-hand coordination instead of awkward compensation elsewhere in the arm.

The second difference is how the fingers are driven. The dual-tendon omnidirectional drive lets the hand open and close, spread sideways and oppose the thumb with independent control of each motion. Tendon drive also brings inherent compliance, and together with the sensing this lets the hand reach sub-millimeter operational precision while adapting to unstructured environments and staying responsive and stable.

The third difference is how much the hand knows about itself and its surroundings. With 400+ tactile sensing units, 20 joint position sensors, motor feedback and a palm camera, the hand does not depend on an outside system to tell it what it is holding. The integrated edge AI compute closes the loop locally, which is why millisecond-level tactile feedback is possible.

How does the 021PRO compare with the other hands in the DexRobot line?

The line is built around choice. The DexHand021 with 19 degrees of freedom is the mass-produced five-fingered option, and the DexHand021 S is the three-fingered hand. The 021PRO sits at the top with 22 joint degrees of freedom and the wrist-hand integrated structure. Every figure on this page belongs to the 021PRO only; we do not carry them over to its siblings.

If you want to compare, the Dexrobot 021MP and the Dexrobot 021 Concept pages describe other versions in the family. Ask us for a quotation and we will help you line the options up against your task.

Who is the Dexrobot 021PRO for?

Research laboratories and universities working on embodied intelligence will find a hand that returns rich touch, position and visual data and runs hybrid position/force control. That is the sort of platform a manipulation study needs, because the data is there from the first day.

Humanoid robot developers need a hand whose wrist and fingers work together, so the 021PRO suits integration teams who want human-like dexterity without designing the wrist themselves. Teams building teleoperation or demonstration-collection systems, where an operator's motion has to be reproduced with care, can also benefit from the 22 degrees of freedom and the tactile feedback.

Industrial and service groups exploring fine assembly, handling of varied objects or tool use in unstructured spaces are another fit. If your work needs only simple grasping, the three-fingered Dexrobot 021S may suit you better, and we are glad to say so.

What is the Dexrobot 021PRO used for?

1. Embodied AI research: a platform that gathers tactile, joint and camera data for learning dexterous skills.
2. Humanoid robotics: a five-fingered hand with an integrated wrist for human-like manipulation.
3. Teleoperation: natural wrist-hand coordination for reproducing an operator's movements.
4. Fine manipulation: sub-millimeter operational precision for careful, delicate handling.
5. Tool use: turning, aligning and flipping objects with coordinated wrist and fingers.
6. Autonomous grasping: edge AI compute and tactile feedback for adapting to unstructured environments.

Summary

The idea behind the 021PRO is simple: a hand is only as useful as the wrist behind it and the touch within it. With 22 joint degrees of freedom, an actively driven wrist, a dual-tendon drive and more than 500 sensing points, it is built to work the way a human hand does. If you are weighing it for research, a humanoid or a teleoperation project, this page is the starting point.
