Unitree H2-D Ultimate I Humanoid Robot

Ask what a robot needs to be useful at a workbench, and the answer is seldom a pair of legs. It is a steady pair of arms, a sensible working height and a way to reach the next station. The Unitree H2-D Ultimate I Humanoid Robot is built around that answer: a wheeled, dual-arm humanoid made for industrial mobile manipulation, where the upper body does the work and the base decides where that work can happen.

The product is available through this page, by quotation.

Background

Unitree Robotics and the H2 lineage

UNITREE ROBOTICS is known for humanoid and legged platforms that are used in research labs, classrooms and integration projects. The H2-D belongs to Unitree's larger H2 series and borrows the upper body of the H2. That matters to buyers who already know the H2 family, because the arms, the torso and the head sensing come from a design that has a track record behind it.

The H2-D then changes the lower half. Instead of walking, it works from a fixed base or rolls on a mobile one, and it comes as the H2-D Fixed Base and the H2-D Mobile Base. Within the wider range you can browse the Unitree H2-D category and the H2-D Ultimate category to see how the Ultimate lettered packages sit next to each other.

Positioning and key technology

The H2-D is positioned as a platform for industrial mobile manipulation. Its arms are force-controlled, with 7 degrees of freedom each, and the Mobile Base version adds omnidirectional mobility, vertical lift and body pitch so the robot can work in confined, complex environments. The Fixed Base version is a precision dual-arm workstation with 24/7 direct-power operation.

The main structure is made of aerospace-grade aluminum, titanium alloy and high-strength engineering plastics. For development teams, the platform offers secondary development through an SDK and intelligent OTA updates. Compute is an Intel i5 for the platform and an Intel i7 for custom development, with high-power compute module options such as Thor.

Technical Specifications

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

The manufacturer has not published the Ultimate I hand model, the total DOF with hands, the dimensions, the IP rating, the operating temperature or what is in the box; they are confirmed at quotation.

What is the difference between the Fixed Base and the Mobile Base?

The two versions share the same upper body. Both have 7-DOF arms, the same peak and rated payload, the same reach, the same cameras, the same waist pitch range and the same lift. What differs is everything under the torso.

The Fixed Base has 19 DOF and runs on direct power, so it can work around the clock at one station. It carries an 864 Wh battery. The Mobile Base has 20 DOF and adds a dual-wheel differential drive with 360° motion, a top speed of 1.5 m/s and a chassis sensor set of LiDAR, depth, collision and ultrasonic units. Its 1.44 kWh battery gives about 5 hours and can be replaced or auto-charged.

In short, the Fixed Base suits a station that never moves, while the Mobile Base suits work that spans several stations. Tell us which of the two fits your task when you request a quotation.

What does the upper body offer for manipulation?

Each arm has 7 degrees of freedom and is force-controlled, with a single-arm reach of about 0.62 m. The payload is peak about 15 kg and rated about 7 kg. The waist pitches from 0° to 115°, and the lift moves at 200 mm/s over 0.5 m of travel, so the arms can be brought to the height of the part rather than the part being brought to the robot.

Vision comes from one head overview camera and two HD wrist cameras. For hands, the platform lists a 2-finger gripper or a 3- or 5-finger dexterous option, so plan your grasp type with the hand in mind.

Who is the Unitree H2-D Ultimate I Humanoid Robot for?

Research labs and universities will find a dual-arm platform with an SDK, OTA updates and room for a higher-power compute module. Integrators can use it as the basis for a custom cell, taking advantage of the choice between fixed and mobile bases. Industrial teams that are evaluating automation for machine tending, part handling or inspection can use it to test ideas before committing to a dedicated line.

If you want to compare other packages in the same family, the sibling versions are listed on their own pages, including the Unitree H2-D Standard J Humanoid Robot and the Unitree H2-D Ultimate A Humanoid Robot. Compare hand options and base type in each before deciding.

What is the Unitree H2-D Ultimate I Humanoid Robot used for?

1. Industrial mobile manipulation: moving between stations and handling parts with two force-controlled arms.
2. Fixed-station dual-arm work: precision tasks at one location on direct power, with the Fixed Base version.
3. Research in manipulation and control: developing algorithms on a 7-DOF dual-arm platform through the SDK.
4. Confined-space operation: working in tight or complex areas with the omnidirectional Mobile Base.
5. Dexterous-hand experiments: testing a 2-finger gripper or 3- or 5-finger hands against real tasks.
6. Teaching and demonstration: showing students and visitors what a humanoid upper body can do.

Delivery, customs and support are arranged with the quotation. The Unitree H2-D Ultimate I Humanoid Robot is available on this page.

Frequently Asked Questions

Is the robot wheeled or legged?

It is a wheeled dual-arm humanoid. The Mobile Base version uses a dual-wheel differential drive with 360° motion, while the Fixed Base version stays at one station.

How much can the arms lift?

The maximum arm payload is a peak of about 15 kg and a rated load of about 7 kg. Single-arm reach is about 0.62 m.

How long does the battery last?

The Mobile Base version runs for about 5 hours on its 48V / 30Ah (1.44 kWh) battery, which is replaceable or auto-charging. The Fixed Base version runs 24/7 on direct power.

Can I develop my own software for it?

Yes. Secondary development through an SDK is supported, and intelligent OTA updates are available. Compute is an Intel i5 for the platform and an Intel i7 for custom development.

Which hands can it use?

The platform lists a 2-finger gripper and 3- or 5-finger dexterous options. Tell us which type your task needs when you request a quotation.

What cameras and sensors does it carry?

Both versions have one head overview camera and two HD wrist cameras. The Mobile Base adds a chassis set of one LiDAR, one depth sensor, two collision sensors and two ultrasonic sensors.

Where can I buy the Unitree H2-D Ultimate I Humanoid Robot and what does it cost?

You can buy it through this page by requesting a quotation. The cost depends on the configuration and is given in the quotation rather than on the page.

Summary

The Unitree H2-D Ultimate I Humanoid Robot answers a simple question: if the work happens at the arms, why build the whole machine around legs? It keeps the upper body of the H2 series, with 7-DOF force-controlled arms, a pitching waist and a lift, and then places it on a fixed or wheeled base. For teams in research, integration or industry that want to test mobile manipulation, this page is the starting point.
