Unitree-H2-D-Ultimate-K

Introduction and Overview

The Unitree H2-D Ultimate K Humanoid Robot is a tactile-first configuration of the wheeled H2-D platform, equipping both arms with BrainCo Revo 3 U21T hyper-dexterous hands that sense pressure, contact, and slip across the entire palm. As vendor-listed, the machine reaches 62 total degrees of freedom on a body shared with the rest of the Unitree H2-D series, including dual 7 degree of freedom arms, a pitching waist, a two axis head, and a motorized column above a differential-drive base. Positioned within the Unitree H2 Humanoid Robots range and the broader Unitree Humanoid Robots catalog, it targets buyers who need reliable touch feedback without the added complexity of camera-in-hand fusion, all under the parent Humanoid Robots category.

H2-D Configurations at a Glance

Every variant in the Unitree H2-D Ultimate tier shares the same mobile body, so the choice comes down to hand technology, while the Standard tier offers a stationary alternative.

Unitree H2-D Ultimate K

Covered on the Ultimate K page, this variant pairs U21T tactile hands with Senyun SHF3L wrist cameras, keeping touch sensing dense while leaving visual perception to the wrists and head.

Unitree H2-D Ultimate L

The Ultimate L steps up to the U21VT visuo-tactile hand, fusing fingertip vision with touch for the most sensor-dense grasping in the family.

Unitree H2-D Ultimate M

The Ultimate M forgoes tactile sensing entirely, using WUJI Dexterous Hand 2 units driven by 1000 Hz force and position hybrid control.

Unitree H2-D Standard M

The Standard M mounts the WUJI hands on a fixed rotating base, serving workcells where the robot does not need to drive.

Technology and Specifications

The Ultimate K measures 1200 × 576 × 620 mm at minimum height and extends to 1700 mm via its 0.5 m column, weighs about 135 kg, and drives at up to 1.5 m/s. Each BrainCo Revo 3 U21T hand provides 21 degrees of freedom, 70 N grip force, 20 N pinch force, 3 Hz open and close cycling, 500 Hz control, and 12 to 80 V operation, with full-palm tactile arrays detecting pressure, contact events, and incipient slip. Each wrist carries a Senyun SHF3L camera under 50 g with a 196 degree horizontal field of view, 1920 × 1536 resolution at 30 fps, an RRGB sensor with built-in ISP, YUV422 8-bit output, rolling shutter, a -40°C to +85°C rating, and Jetson AGX Thor compatibility. Perception and navigation use one LiDAR, one depth camera, two physical collision sensors, and two ultrasonic sensors. A 48 V, 30 Ah, 1.44 kWh battery yields about 5 hours of operation with battery swap, an automatic charging station, and an external supply option. Compute is dual Intel, a Core i5 and a Core i7, with optional Jetson Thor and i7 or Orin NX expansion, plus a binocular head carrying an 8-core CPU and a 10 TOPS NPU.

Applications and Use Cases

Contact-Rich Industrial Tasks

Slip detection and palm-wide pressure maps suit insertion, fastening, and part seating operations where grip stability must be confirmed by touch rather than assumed.

Logistics and Material Handling

The hands can adapt grip force to packages of unknown weight and stiffness, reducing drops and crush damage during picking, sorting, and tote handling.

Tactile Manipulation Research

Dense tactile arrays at 500 Hz control provide clean data for grasp stability studies, slip-aware controllers, and touch-conditioned learning policies.

Advantages and Benefits

• Full-palm touch: pressure, contact, and slip detection across the whole hand surface, not just fingertips.
• Grip assurance: 70 N grip and 20 N pinch force combined with slip feedback keep variable objects secure.
• Simpler than fusion systems: tactile-only sensing avoids the calibration and compute overhead of visuo-tactile hands while retaining touch.
• Mobile reach envelope: the driving base, 0.5 m lift column, and dual 7 DOF arms cover floor-to-shelf workspaces.
• Fleet-friendly power: about 5 hours per battery with swapping and automatic charging supports multi-shift schedules.

Pricing and Availability

The Unitree H2-D Ultimate K is for sale through Robots International. Price and cost vary by model, optional compute, fleet size, and destination, so figures are confirmed through quotation rather than a universal list price. Buyers should request a quotation for current pricing and delivery terms, and purchasing details are available on this page. Additional platforms are listed in the Shop.

Frequently Asked Questions

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

It is a mobile dual-arm humanoid robot in the Unitree H2-D Ultimate series, vendor-configured with BrainCo Revo 3 U21T full-palm tactile hands and 62 total degrees of freedom.

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

Dual Intel computers run navigation and arm control while each U21T hand closes a 500 Hz loop over palm-wide pressure, contact, and slip signals to regulate grasp force.

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

It makes dense tactile manipulation available on a production-style mobile humanoid, letting operators verify grip by touch in tasks where vision alone is unreliable.

What are the benefits?

Buyers get slip-aware grasping, strong grip force, wrist cameras, long swappable battery runtime, and interchangeability with other H2-D variants in mixed fleets.

How does the U21T differ from the U21VT hand?

The U21T senses touch only, while the U21VT on the Ultimate L adds visual sensing inside the hand for visuo-tactile fusion; both share 21 DOF and similar force ratings.

What sensors handle navigation?

The vendor lists one LiDAR, one depth camera, two physical collision sensors, and two ultrasonic sensors, alongside the binocular head unit.

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

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

Summary

The Unitree H2-D Ultimate K delivers palm-wide touch on a proven mobile humanoid body, occupying the practical middle ground between force-only and visuo-tactile hands. For teams specifying tactile dual-arm manipulation, this page is the definitive starting point.
