Unitree H2-Dedicated Dex3-1 Force-Controlled Three-Finger Dexterous Hand — Single Unit

Choosing a hand for a humanoid is rather like choosing a lens for a camera body: the body sets what is possible, but the lens decides what you actually capture. A Unitree H2 can walk, balance and reach, yet the quality of its work at a bench, a shelf or a demonstration table is settled by what sits at the end of each arm. The Unitree H2-Dedicated Dex3-1 Force-Controlled Three-Finger Dexterous Hand — Single Unit is a compact, sensing hand that turns the H2's reach into deliberate, measurable grasping, with a control design aimed at gripping firmly without crushing.

Robots Middle East supplies this hand to universities, research laboratories, system integrators and corporate innovation teams across the Middle East. We prepare a formal quotation for each enquiry, match the configuration to your H2 platform, and arrange delivery, documentation and after-sales support for your site in the region.

Background

Unitree Robotics and its humanoid line

Unitree Robotics built its reputation on agile legged robots before extending its range into full-size and compact humanoids. Over that time the company has developed its own actuators, motor controllers and software tooling, which is why its humanoid accessories are designed as part of a single ecosystem rather than as generic add-ons. The H2 sits within this humanoid family, and Unitree offers a set of end effectors for it, from simpler grippers to multi-fingered hands from both Unitree and partner manufacturers. The Dex3-1 is Unitree's own three-finger design within that set, offered for the H2 as a left hand, a right hand or a pair; this listing covers a single unit.

Force and position hybrid control

The defining idea of the Dex3-1 is that it combines force and position hybrid control, which makes the hand sensitive and reliable. In practice, a position-only hand drives each finger to a target angle regardless of what it meets, while a hand that also regulates force can stop, yield or hold steady once contact is made. The Dex3-1 has 7 degrees of freedom: 6 joints are micro brushless force control joints in direct drive, and 1 is a micro brushless force control joint with gear drive. Direct drive keeps the path between motor and finger short, which is generally favourable for responsive force control, while the geared joint adds torque where the design calls for it. A layer of pressure sensors across the hand provides the feedback that makes this approach useful in real grasping.

Technical Specifications

The table below sets out the figures for the Dex3-1 hand itself, from its control concept to its sensing and electrical characteristics.

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published an IP rating for the hand or the contents of the box; both are confirmed with your quotation.

Is the Dex3-1 for the H2 the same hand Unitree offers for the G1?

The Dex3-1 can be used with the G1 humanoid robot to perform various complex actions, and Unitree also offers it in a version dedicated to the H2, available as a left hand, a right hand or a pair. The hand's core design, its force and position hybrid control and its sensing layout are described in the same terms for both, but mounting, cabling and software integration are specific to each platform. For that reason, Robots Middle East matches the H2 variant, its handedness and its interface to the arm it is going onto when preparing your order, so that the hand you receive fits the robot you already have.

What makes force and position hybrid control useful in a three-finger hand?

A three-finger layout is a deliberate compromise. It gives up some of the anthropomorphic dexterity of a five-finger hand in exchange for fewer joints to coordinate and a simpler control problem. That trade only pays off if each finger is well controlled, and this is where the Dex3-1's design matters. With force control on every joint, the hand can close around an object until contact is detected, then regulate how hard it squeezes rather than simply driving to a fixed angle.

The pressure sensors close the loop. The hand carries 9 pressure sensor positions with a total of 33 pressure sensors and a range of perception of 10g-2500g, so the controller receives information from light touches through to firm holds. A communication rate of 1000Hz over USB2.0 gives software frequent updates on that state, and rotor absolute value encoders on the joint modules report finger positions without needing to re-home. Combined with a fingertip repeat positioning accuracy of ±2mm, this makes the hand suited to repeatable experiments in grasping, where the same motion must be reproduced across many trials and the data compared fairly.

Who is the Unitree H2-Dedicated Dex3-1 hand for?

The first group is university and institutional research teams working on manipulation, grasp planning and learning from demonstration. For them, a hand with force feedback and a dense set of pressure sensors provides the data that modern learning methods depend on, and the three-finger layout keeps the control space manageable for students and researchers alike.

The second group is system integrators and applied robotics teams evaluating whether a humanoid can take on handling tasks in logistics, laboratories or light assembly. They need a hand that matches the H2 mechanically and electrically and that behaves predictably on contact, which is the focus of this design.

The third group is innovation centres, exhibition teams and educators who want an H2 that can interact with objects convincingly in front of visitors or classes, and who value a compact hand with a straightforward interface.

Buyers whose projects centre on touch should also look at the Unitree H2-Dedicated Dex3-1 Tactile Three-Finger Dexterous Hand — Single Unit, a separate version of this three-finger design. Teams who need a more human-like grasp may wish to compare five-finger options such as the Unitree H2-Dedicated Dex5-1P Tactile Five-Finger Dexterous Hand with RGB— Single Unit (Left or Right) or the Unitree H2-Dedicated BrainCo Revo 2 Basic Dexterous Hand — Single Unit (Left or Right). The full range of end effectors and add-ons for the platform is gathered under H2 Accessories.

What is the Unitree H2-Dedicated Dex3-1 hand used for?

1. Grasping research: studying how a humanoid approaches, closes on and holds objects of differing shape and stiffness.
2. Robot learning datasets: recording joint positions and pressure readings to train and evaluate manipulation policies.
3. Teleoperation studies: mapping an operator's hand motions onto a force-controlled robot hand for remote handling trials.
4. Pick-and-place evaluation: testing whether an H2 can move items between shelves, trays and workstations reliably.
5. Teaching and training: giving engineering students a practical platform for control, sensing and embedded software coursework.
6. Demonstrations and visitor engagement: showing a humanoid handing over, holding and presenting objects at exhibitions and innovation centres.

Summary

If the H2 is the camera body, the Dex3-1 is a lens chosen for precise, controlled work rather than breadth. Its three-finger layout keeps the control problem tractable, its force and position hybrid control lets each finger respond to contact, and its pressure sensors and absolute encoders give researchers and integrators the data they need to judge every grasp. For teams that want their H2 to handle objects with intent rather than force alone, supplied and supported by a regional partner, this page is the starting point.
