Unitree H2 Plus ULTIMATE-I Humanoid Robot

A humanoid earns its keep not in the legs but in the fingers. Any capable biped can cross a floor; the harder question is what happens when it reaches for a part, a tool or a sample and has to feel whether the grip will hold. The Unitree H2 Plus ULTIMATE-I Humanoid Robot answers that question with two tactile Inspire RH56E2 hands, set on a full-size body built for research and development work.

Background

Unitree Robotics and the H2 Plus lineage

Unitree Robotics is a manufacturer of legged and humanoid robots, and the H2 Plus is one of its full-size humanoid families. The sources name several versions in this family: H2 Plus Standard, H2 PLUS SMART, and a lettered range from H2 PLUS ULTIMATE-A to ULTIMATE-N. Each version pairs the same general body with a different combination of computing and hands. The ULTIMATE-I is the version described on this page, and every figure here belongs to it.

Teams that want to compare the family can look at the Unitree H2 Plus Standard Humanoid Robot, the Unitree H2 Plus SMART Humanoid Robot and the Unitree H2 Plus ULTIMATE A Humanoid Robot. The whole range is gathered in the Unitree H2 Plus category.

Positioning and key technology

The ULTIMATE-I stands 1820 mm tall in its standing posture and has 31 degrees of freedom in the body. Adding the hands brings the total to 43. Joint torque reaches up to 120 Nm in the arms and 360 Nm in the legs, which gives the frame the strength to carry its own mass and still work with its arms.

What sets this version apart is the hand. Each of the two Inspire RH56E2 hands has five fingers, 6 degrees of freedom, 17 tactile sensors and a wrist RGB camera. The thumb delivers 30 N of force and the other fingers 28 N. Sensing at the fingertip, together with vision at the wrist, lets a program react to contact rather than only to what a camera sees.

The robot also supports secondary development. Its computing is split between an Intel Core i5 for platform functions and an Intel Core i7 reserved for user development, so a team's own software does not have to compete with the functions that keep the robot running.

What makes the ULTIMATE-I different from the other H2 Plus versions?

The difference is concentrated in the hands and in the sensing around them. The family shares a common body, so the choice between versions is largely a choice about what the robot does at the end of its arms. The ULTIMATE-I carries tactile Inspire RH56E2 hands, each with 17 tactile sensors and its own wrist camera. That combination gives a control program two kinds of information about an object: what it looks like from the wrist, and how it feels under the fingers.

For a team that mainly needs a walking and perception platform and plans to choose its hands later, the Standard version is the more natural starting point. The ULTIMATE-I is for groups that already know their work depends on contact.

What does the head camera and onboard computing offer a developer?

The head-mounted stereo camera covers a horizontal field of view of 140° ±3° and a vertical field of view of 102° ±3°. It uses a global shutter, which avoids the skew that a rolling shutter introduces when the robot or the scene is moving. Depth of field runs from 0.4 m to infinity, so the same camera serves for close manipulation and for looking across a room.

Behind the sensors sit 128 GB of LPDDR5X memory on a 256-bit bus at 273 GB/s, and a split Intel computing arrangement. The interface list is generous: three USB 3.0 ports, four Gigabit Ethernet ports, four GMSL links, four RS-485 lines and two CAN buses, among others. A lab adding its own cameras, controllers or instruments will find real connectors rather than a sealed box. Wi-Fi 6 and Bluetooth 5.2 cover wireless work.

Who is the Unitree H2 Plus ULTIMATE-I for?

University and corporate research groups are the clearest fit. Teams working on manipulation, imitation learning or human-robot interaction need a hand that reports contact, and they need to write their own software on a platform that allows it. The dedicated development processor and the secondary development support are aimed at them.

System integrators form a second group. They can evaluate the robot for tasks that involve handling varied objects before committing to a larger program. Training centers and innovation labs may also value a full-size humanoid whose hands are a visible part of the demonstration.

Buyers who do not need tactile hands may be better served elsewhere in the range. The SMART version is a different configuration, and the Unitree H2 Plus Humanoid Robot page gives the family overview. Ask for a quotation and we will help match the version to the work.

What is the Unitree H2 Plus ULTIMATE-I used for?

1. Dexterous manipulation research. Five-finger hands with 17 tactile sensors each let teams study grasping, regrasping and slip detection.
2. Embodied AI development. Dedicated user-development computing and large memory give learning models a place to run on the robot itself.
3. Human-robot interaction studies. A full-size body with wide-angle vision suits work on handovers, gestures and shared spaces.
4. Teleoperation and data collection. Wrist cameras and tactile feedback give operators and datasets richer records of each task.
5. Integration testing. CAN, RS-485, GMSL and Ethernet ports allow external sensors and tools to be attached and tested.
6. Teaching and demonstration. A humanoid of this size lets students and visitors see a complete robotics system in action.

Frequently Asked Questions

How many degrees of freedom does the ULTIMATE-I have?

It has 43 degrees of freedom in total. The body accounts for 31, and each hand adds 6.

What hands does this version use?

It uses two tactile Inspire RH56E2 hands with five fingers and wrist RGB cameras. Each hand weighs 790 g and has 17 tactile sensors.

How strong are the hands?

The thumb delivers 30 N of force and the other fingers 28 N.

How long does the battery last?

Runtime is approximately 3 hours from the 15 Ah, 0.972 kWh removable smart battery.

Can we run our own software on it?

Yes, secondary development is supported. An Intel Core i7 is provided for user development, apart from the Intel Core i5 that handles platform functions.

What is its weight?

With the battery it weighs approximately 70 kg, excluding the hand configuration. Its standing dimensions are 1820 × 456 × 218 mm.

Where can I buy the Unitree H2 Plus 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 quantity and the destination, and it is given in the quotation rather than printed here.

Summary

The Unitree H2 Plus ULTIMATE-I Humanoid Robot puts its strength in the legs, with up to 360 Nm, and its value in the fingers, with 17 tactile sensors in each hand. Around them sit a wide-angle head camera, wrist cameras, generous memory and a split computing design that leaves room for a team's own code. It suits groups whose work depends on touch, and the rest of the H2 Plus family covers other needs. If your project calls for a humanoid that can feel what it holds, this page is the starting point.
