Unitree H2 Dex1-1 Gripper Standard Version

Most end effectors are judged by what they can hold. The Unitree H2 Dex1-1 Gripper Standard Version deserves to be judged just as much by what it reports. Each time its jaws close, the gripper returns angle, angular velocity, torque and temperature over a high-speed 485 link at a control frequency of 1000Hz. For a humanoid that has to learn, adapt and be debugged, that stream of data is often worth more than any extra finger. This is a parallel gripper with an adjustable force range and a 90mm stroke. It is designed for teams that want their robot's grasp to be measurable as well as strong.

Robots Middle East supplies the Unitree H2 Dex1-1 Gripper Standard Version to universities, research institutes, system integrators and industrial innovation teams across the Middle East. Robots Middle East prepares each quotation for the specific H2 configuration a customer is building. It also coordinates delivery and import formalities, and remains the point of contact for technical support once the gripper is in service.

Background

Unitree Robotics and the H2 platform

Unitree Robotics built its reputation on agile legged robots, first quadrupeds and then full-size humanoids. The company aims to make advanced locomotion accessible to laboratories and developers, not only to large corporate research groups. The H2 is its full-size humanoid platform, and its usefulness depends heavily on what is mounted at the wrist. Unitree therefore offers a family of end effectors for the H2, ranging from parallel grippers to multi-fingered hands. Buyers can match the robot's hands to the work it is expected to do. The Dex1-1 is the parallel-gripper option in that family.

A parallel gripper with a closed feedback loop

The Dex1-1 is driven by a single motor through a 1:25 reduction. A 15bit absolute encoder reports the motor position, so the controller knows where the jaws are from the moment the system powers up. Gripping force, closing speed and fingertip position are all adjustable, and the fingertip position resolution is 0.1mm. In practice, the same tool can close gently on a delicate component or firmly on a heavy tote, depending on the parameters the control software sends. The Dex1-1 carries two separate grasp-load figures: one for form-fitting grasps, where the jaws lock around the object's shape, and one for friction grasps, where only contact pressure holds the load. Engineers should plan tasks with that distinction in mind.

What does the Advanced Version add over the Standard Version?

The difference between the two versions is vision. The Standard Version ships with a D405 camera bracket, but without the D405 camera itself. The Advanced Version (with Camera) adds a camera rated at 1080P, 30/60 FPS and a field of view of H:118° V:87° D:140°. Those camera figures belong to the Advanced Version alone; they are not a specification of the Standard Version.

For many buyers, the Standard Version is the more sensible choice for exactly this reason. A laboratory that already owns suitable cameras, or that runs perception from sensors mounted elsewhere on the robot, gains nothing from paying for a second camera at the wrist. The included bracket keeps the option open, because a camera can be fitted later without redesigning the mount. The 485-to-USB board in the box is also practical: it allows the gripper to be connected to a workstation for bench testing before it is fitted to the robot.

How does a parallel gripper compare with a dexterous hand on the H2?

A parallel gripper and a multi-fingered hand address different problems. A dexterous hand can reproduce human hand poses, manipulate tools and perform in-hand repositioning. The trade-offs are more joints to calibrate, more failure points and a more complex control problem. A parallel gripper does fewer things but does them predictably. Its single degree of freedom is easy to model in simulation, easy to command from a learning policy and easy to verify on the bench. The Dex1-1 combines that simplicity with adjustable force and speed and a rich feedback channel. It therefore suits pick-and-place, fixture loading and teleoperation data collection, where repeatability matters more than finger articulation. Teams whose research centres on dexterous manipulation will find the Unitree H2 Dex5-1 Five Finger Hand a more natural fit.

Who is the Unitree H2 Dex1-1 Gripper Standard Version for?

The first group is research laboratories working on humanoid manipulation, imitation learning and teleoperation. They need a robust, well-instrumented end effector that does not dominate their control stack. The angle, velocity, torque and temperature feedback gives them ground truth for every grasp, and the 1000Hz control frequency leaves room for closed-loop experiments.

The second group is system integrators and industrial innovation teams evaluating the H2 for logistics, assembly support or material handling pilots. For them, the grasp loads, the recommended operating environment of -20℃ ~ 60℃ and the 24V~64V supply range are the figures that matter most when planning a proof of concept. A humanoid typically uses two grippers, so most integration projects should budget for a pair.

The third group is universities and training centres teaching robotics. A single-axis gripper is an excellent teaching tool for control theory, communication protocols and grasp planning.

Buyers who want vision at the wrist out of the box should look at the Unitree H2 Dex1-1 Gripper Advanced Edition. The Unitree H2 Dex1-1 Gripper Ultimate Edition is also offered, and its contents are best compared directly on a quotation. The wider range of compatible end effectors and spares is listed under H2 Accessories.

What is the Unitree H2 Dex1-1 Gripper Standard Version used for?

1. Teleoperation data collection: a simple, repeatable grasp produces clean demonstration data for training manipulation policies.
2. Pick-and-place research: adjustable force and speed allow the same gripper to handle fragile and robust objects in one experiment.
3. Logistics pilots: form-fitting grasps of totes and cases test whether a humanoid can take on warehouse handling tasks.
4. Assembly and fixture loading: fine fingertip position control supports placing parts into jigs and fixtures.
5. Control and protocol teaching: the high-speed 485 link and detailed motor feedback make the gripper a practical classroom subject.
6. Grasp benchmarking: separate form-fitting and friction loads give a clear framework for comparing grasp strategies.

Frequently Asked Questions

Is a camera included with the Standard Version?

No. The Standard Version includes a D405 camera bracket, but the D405 camera itself is not supplied. The Advanced Version (with Camera) is the option that includes a camera.

What is in the box?

The box contains one Dex1-1 gripper, one D405 camera bracket, one 485-to-USB board, and cables and accessories.

How many grippers does an H2 humanoid need?

Typically, two grippers are used per humanoid robot, one for each arm. Most projects therefore order a pair.

How strong is the grip?

The gripping force is adjustable from 5~120N. The grasp load is 20kg for form-fitting grasps and 5kg for friction grasps.

What power supply does it need?

The operating voltage is 24V~64V, and 24/48VDC is recommended. The static current is 0.03A and the peak line current is 3.5A.

In what temperatures can the gripper operate?

The recommended operating environment is -20℃ ~ 60℃. This range covers most laboratory, workshop and warehouse settings.

Where can I buy the Unitree H2 Dex1-1 Gripper Standard Version and what does it cost?

You can obtain it from Robots Middle East, which supplies it across the Middle East. The cost is set out in a tailored quotation that covers quantity, configuration, delivery and support. Please request yours from this page.

Summary

The Unitree H2 Dex1-1 Gripper Standard Version earns its place on the H2 by being both strong and communicative. It offers an adjustable grasp, a 90mm stroke and form-fitting loads of 20kg. It also feeds angle, velocity, torque and temperature back to the controller at 1000Hz. That combination makes every grasp measurable, which is what research and integration teams need when a humanoid moves from demonstration to dependable work. Teams with their own vision setup get a lean, camera-ready package, while those who want wrist vision can step up to the Advanced Version.
