Unitree H2 Dex1-1 Gripper Advanced Edition

A humanoid robot can cross a workshop floor with confidence and still fail in the last few centimeters, where jaw meets object. The Unitree H2 Dex1-1 Gripper Advanced Edition is built for that moment: a compact electric parallel gripper meant for reliable, high-speed grasping in robotics and AI work.

This gripper is available through this page, by quotation.

Background

Unitree and the H2 family

Unitree Robotics is known for legged and humanoid robots, and its H2 humanoid platform comes with a growing set of accessories, including batteries, a charger and several hand options. The Dex1-1 gripper sits in that ecosystem as a simple, practical end effector. Teams that want a robot to pick things up, carry them and put them down often start here before moving to more complex hands.

The Advanced Edition is the single-hand configuration. Typically two grippers are selected per humanoid robot, one for each arm, so a buyer building a two-armed setup should plan on a pair. The same gripper is also offered as a Standard version and an Ultimate edition, each with its own page.

What the Dex1-1 is designed to do

Unitree describes the Dex1-1 as a compact electric parallel gripper for reliable, high-speed grasping. A parallel gripper closes two jaws toward each other along a straight line. It has fewer moving parts than a multi-finger hand, and it is easier to control and to repeat. For many pick-and-place tasks, and for collecting grasp data to train AI models, that simplicity is an advantage rather than a limit.

The gripper is driven by a motor with an absolute encoder and reports its angle, angular velocity, torque and temperature back to the controller. Communication runs over a high-speed 485 protocol. That gives a developer both control and a clear view of what the gripper is doing at any moment.

What makes the Dex1-1 different from a five-finger hand?

The main difference is the philosophy. A five-finger hand such as the Unitree H2 Dex5-1 Five Finger Hand aims at human-like dexterity. The Dex1-1 aims at dependable, fast and repeatable gripping. Its two jaws travel through a 90mm stroke, and its fingertip position resolution is 0.1mm, so a controller can place the jaws with fine steps even though the motion is simple.

Speed and force show the same character. The gripper closes the full stroke in as little as 0.24s, and its speed is adjustable from 50 to 375 mm/s. Gripping force is adjustable from 5 to 120N, so one gripper can handle a light, delicate item at low force and a heavier item at high force. The grasp load is 20kg for a form-fitting hold and 5kg for a friction hold. A form-fitting hold is one where the jaws wrap around the object, so shape does part of the work.

Weight matters on a humanoid arm. At 550g and 143mm × 78mm × 67mm, the gripper is small enough to sit at the end of an arm without adding much load. A buyer who needs individual finger movement should look at the dexterous hands instead. A buyer who needs a robust, quick and easy-to-control grasp will find the Dex1-1 a sensible fit.

What does the Advanced Edition mean for my setup?

The fact sheet describes the Advanced Edition as a single-hand configuration, with two grippers typically selected per humanoid robot. In practice, a buyer equipping both arms should ask for a pair. The sources name Standard, Advanced and Ultimate versions, and also list V2 (Advanced Edition) and V3 (Ultimate edition). They do not set out how these versions differ in their figures, so the table above makes no comparison between them.

If version differences decide your purchase, tell us what you need when you request a quotation and we will confirm the exact contents of each version against the datasheet. That is a safer route than assuming that a sibling's features carry over.

Who is the Unitree H2 Dex1-1 Gripper Advanced Edition for?

Research labs working on embodied AI are a natural audience. A gripper with an absolute encoder and feedback on angle, angular velocity, torque and temperature gives a team the signals it needs to log and study each grasp. The 1000Hz control frequency and 6Mbps baud rate suit work where timing matters.

Integrators building humanoid systems for pick-and-place, handling or demonstration tasks will value the compact body and the wide supply range of 24V to 64V, with 24 or 48VDC recommended. Universities and training centers can use the gripper to teach manipulation, since its behavior is easy to understand and easy to explain to students.

Buyers who want the same gripper in another version can look at the Standard version or the Ultimate edition, linked in the Background section above. Those who need finger-level dexterity should consider the Dex5-1 Five Finger Hand. Supporting items, such as batteries and chargers, are gathered under H2 Accessories.

What is the Unitree H2 Dex1-1 Gripper Advanced Edition used for?

1. Pick-and-place work. The quick closing time and adjustable speed suit repeated moves of objects from one place to another.
2. Grasp data collection. Torque, angle, angular velocity and temperature feedback support logging for AI training.
3. Handling mixed loads. Adjustable force from 5 to 120N lets one gripper deal with light and heavier items.
4. Two-armed humanoid tasks. A pair of grippers lets a humanoid robot hold and carry objects with both hands.
5. Teaching and demonstrations. A simple parallel motion makes manipulation easy to show in classrooms and labs.
6. Integration trials. Engineers can test the gripper on a robot before committing to a wider rollout.
