Unitree-H2-D-Ultimate-M

Introduction and Overview

The Unitree H2-D Ultimate M Humanoid Robot is a mobile, dual-arm manipulation platform built on the wheeled H2-D architecture within the Unitree H2 Humanoid Robots family. As vendor-listed, the configuration pairs two 7 degree of freedom arms with WUJI Dexterous Hand 2 end effectors, a motorized lifting column, and a differential-drive chassis, reaching 60 total degrees of freedom. Unlike its tactile-equipped siblings, the Ultimate M omits tactile skin in favor of high-frequency force and position control, running MIT Force/Position Hybrid Control at 1000 Hz across 20 axes per hand. It belongs to the broader category of Humanoid Robots and, more specifically, the Unitree Humanoid Robots portfolio, where wheeled H2-D platforms complement legged designs such as the Bipedal Humanoids line.

The Unitree H2-D Family

The Unitree H2-D series adapts the H2 humanoid upper body to wheeled bases, and is offered in Standard and Ultimate tiers that differ mainly in mobility and hand technology.

Unitree H2-D Ultimate M

The subject of this page, the Ultimate M combines the mobile chassis with WUJI Dexterous Hand 2 units, prioritizing control bandwidth and back-drivable kinematics rather than tactile sensing.

Unitree H2-D Ultimate L

The Ultimate L substitutes BrainCo Revo 3 U21VT visuo-tactile hands, adding fused visual and tactile perception at the fingertips and palm for 62 total degrees of freedom.

Unitree H2-D Ultimate K

The Ultimate K uses BrainCo Revo 3 U21T tactile hands with full-palm pressure, contact, and slip detection, aimed at contact-rich handling without camera-in-hand fusion.

Unitree H2-D Standard M

The Standard M keeps the WUJI hands but replaces the driving chassis with a fixed base offering in-place rotation, suiting stationary workcells.

Technology and Specifications

The Ultimate M stands between 1200 and 1700 mm tall thanks to its 1 degree of freedom motorized column with 0.5 m of vertical travel, measures 576 × 620 mm in footprint, and weighs about 135 kg. The differential-drive base rotates 360 degrees in place, reaches 1.5 m/s, and turns within a diameter of about 0.75 m. Each WUJI Dexterous Hand 2 provides 20 degrees of freedom with direct-drive rotary joints, fingertip peak force of at least 15 N, open and close cycling of at least 4 Hz, joint backlash under 1 degree, full opposition grasp with lateral swing, a minimum grasp diameter of zero, and 1000BASE-T EtherNet connectivity, with a 1920 × 1080 RGB wrist camera per hand covering a 130 degree diagonal field of view. Compute is vendor-listed as dual Intel platforms, a Core i5 PC1 and Core i7 PC2, with optional Jetson Thor PC3 and i7 or Orin NX PC4 modules, plus a binocular head unit with an 8-core CPU and 10 TOPS NPU. Navigation relies on one LiDAR, one depth camera, two physical collision sensors, and two ultrasonic sensors. Power comes from a 48 V, 30 Ah, 1.44 kWh battery rated for about 5 hours, with battery swap, an automatic charging station, and external supply options.

Applications and Use Cases

Research and Development

The combination of back-drivable hands, high-frequency hybrid control, and open dual-computer architecture makes the platform well suited to manipulation research, imitation learning, and teleoperation data collection.

Light Industrial Handling

With its lifting column and mobile base, the robot can move between stations, pick and place parts, and perform bin handling tasks where tactile feedback is not required but repeatable force control is.

Service and Demonstration Environments

The humanoid form, wrist cameras, and safe navigation stack support customer-facing demonstrations, showroom operation, and telepresence style tasks in structured public spaces.

Advantages and Benefits

• High-bandwidth manipulation: 1000 Hz force and position control across 20 axes per hand enables precise, compliant grasping without tactile hardware.
• Extended vertical reach: the 0.5 m column moves the workspace from low bins to elevated shelving on a single platform.
• Long duty cycles: an approximately 5 hour battery, swap capability, and automatic charging station support sustained operation.
• Layered compute: dual Intel computers, an optional Jetson Thor, and a 10 TOPS NPU head allow perception, planning, and control to run on separate resources.
• Family compatibility: software and tooling carry over across the H2-D line, easing upgrades toward tactile variants.

Frequently Asked Questions

What is Unitree-H2-D-Ultimate-M?

It is a mobile dual-arm humanoid robot in the Unitree H2-D Ultimate series, vendor-configured with WUJI Dexterous Hand 2 end effectors, a lifting column, and a differential-drive chassis totaling 60 degrees of freedom.

How does Unitree-H2-D-Ultimate-M work?

Two 7 DOF arms and 20 DOF hands are coordinated by dual Intel computers, guided by LiDAR, a depth camera, ultrasonic and collision sensors, while MIT Force/Position Hybrid Control at 1000 Hz governs grasping.

Why is Unitree-H2-D-Ultimate-M important?

It shows that dexterous, mobile, dual-arm manipulation can be delivered without tactile skin by relying on fast, back-drivable force control, lowering complexity for many practical tasks.

What are the benefits?

Buyers gain a full mobile manipulation stack, long battery runtime with swap and auto-charging, wrist cameras on both hands, and an expandable compute architecture in one integrated platform.

Does the Ultimate M have tactile sensing?

No, the WUJI Dexterous Hand 2 configuration omits tactile arrays. Applications needing touch feedback are better served by the Ultimate L or Ultimate K variants.

How long does the battery last?

The vendor lists a 48 V, 30 Ah, 1.44 kWh battery with about 5 hours of runtime, plus battery swap, an automatic charging station, and external power operation.

Where can I buy Unitree-H2-D-Ultimate-M and what does it cost?

It is for sale through Robots International with worldwide delivery, customs handling, and support. Cost depends on configuration and destination, so request a quotation, with details on this page.
