H2-D Ultimate K — mobile dual-arm humanoid with BrainCo Revo 3 U21T tactile hyper-dexterous hands, differential-drive chassis with LiDAR navigation

What's in This Configuration

The H2-D Ultimate K features BrainCo Revo 3 U21T tactile hyper-dexterous hands — a 21-DOF five-finger hand platform with full-palm tactile sensing, 70 N grip force, and 20 N pinch force designed for maximum dexterity manipulation research with tactile feedback. Each hand delivers 21 active DOF (4 fingers × 4 + thumb 5) with an open/close speed of 3 Hz and control frequency of 500 Hz, operating at 12–80 V. The Revo 3 U21T achieves a powerful 70 N grip force and 20 N pinch force for robust object handling across diverse manipulation tasks. Full-palm tactile sensing provides real-time pressure, contact, and slip detection across the entire hand surface for closed-loop force control and delicate object handling. Each hand includes a Senyun SHF3L wrist camera — a compact vision module weighing <50 g with a 196° HFOV, 1920×1536 resolution at 30 fps, RRGB sensor, built-in ISP, and YUV422 8-bit output. The camera operates from −40°C to +85°C and is compatible with NVIDIA Jetson AGX Thor. The 1-DOF motorized column (0.5 m vertical travel) combines with dual 7-DOF arms, a 1-DOF waist (0°–115° pitch), and a 2-DOF head to deliver a 62-DOF manipulation system. The mobile base reaches 1.5 m/s with 360° in-place rotation, equipped with LiDAR, depth camera, collision sensors, and ultrasonic sensors for autonomous navigation. The built-in 48V/30Ah battery (1.44 kWh) provides approximately 5 hours of runtime with support for battery swap and automatic recharging via the included charging station. A visualization computer is included as standard for monitoring and development.

Dual 7-DOF Arms. Industrial-Grade Kinematics. Human-Like Dexterity.

The H2-D Ultimate K is engineered around two 7-DOF high-performance arms, each driven by low-inertia inner-rotor PMSM motors with crossed-roller and double-row ball bearings. With ~0.62 m reach per arm and a ~7 kg rated payload per arm (up to ~15 kg peak), it handles precise assembly, heavy pick-and-place, and industrial manipulation research with human-like fluidity. The extra two degrees of freedom per arm provide kinematic redundancy — the arm can maintain end-effector pose while reconfiguring its elbow to avoid obstacles, reach around corners, or optimize for natural motion. Dual encoders on every joint deliver closed-loop precision.

 

Building on the biomimetic design philosophy of the H2 series, Unitree H2-D Ultimate features a mobile humanoid architecture with multimodal perception and an open development framework. Designed for industrial manipulation, commercial services, robotics research, and embodied AI training.

Autonomous Mobile Chassis — Navigate, Explore & Interact

Unlike the fixed-base H2-D Standard, the H2-D Ultimate features a differential-drive mobile chassis that brings the robot to your environment. With a top speed of 1.5 m/s and 360° in-place rotation (turning diameter ~0.75 m), it navigates warehouses, labs, and service floors with ease. The comprehensive sensor suite includes LiDAR for SLAM mapping, a depth camera for obstacle detection, physical collision sensors for safety bumpers, and ultrasonic sensors for close-range object avoidance. The built-in 48V/30Ah battery (1.44 kWh) delivers approximately 5 hours of continuous operation and supports both manual battery swap and automatic recharging at the included charging station.

1-DOF Motorized Column — Expand Your Workspace Vertically

The 1-DOF motorized column provides 0.5 m of vertical travel at speeds up to ~200 mm/s. This transforms the robot from a compact 1200 mm unit to a 1700 mm tall workstation — enabling floor-level picking, mid-height assembly, and overhead shelf access while the chassis remains stationary or in motion. Combined with the 1-DOF waist (0°–115° pitch) and 7-DOF arms, H2-D Ultimate achieves a full spherical workspace spanning from the ground to a height of 2 m — ideal for warehouse logistics, assembly lines, and service robotics.

BrainCo Revo 3 U21T Tactile Hyper-Dexterous Hands — 21-DOF with Full-Palm Tactile Sensing

The BrainCo Revo 3 U21T is a 21-DOF tactile hyper-dexterous five-finger hand designed for maximum dexterity manipulation research with full-palm tactile feedback. Each hand delivers 21 active DOF (4 fingers × 4 + thumb 5) — providing independent control over every finger segment for natural, human-like grasping and manipulation. The Revo 3 U21T achieves a powerful 70 N grip force and 20 N pinch force for robust handling of objects across a wide range of weights and shapes. Full-palm tactile sensing delivers real-time pressure, contact, and slip detection across the entire hand surface for closed-loop force control and delicate object handling. With an open/close speed of 3 Hz and a control frequency of 500 Hz, the U21T delivers rapid, precise response for dynamic manipulation tasks. Operating voltage ranges from 12–80 V for flexible power integration. Each hand includes a Senyun SHF3L wrist camera — an ultra-compact vision module weighing <50 g with dimensions of 25×25×33.54 mm. The SHF3L features a 196° horizontal FOV, 1920×1536 resolution at 30 fps, RRGB sensor, built-in ISP, and YUV422 8-bit output with rolling shutter. Engineered for extreme environments, it operates from −40°C to +85°C and is compatible with NVIDIA Jetson AGX Thor. Accessories include the wrist camera, mounting bracket, and cables.

1-DOF Waist — Flexible Body Pitch

The 1-DOF waist joint provides 0°–115° pitch, enabling the robot to bend forward for floor-level picking, lean back for overhead access, and orient toward workstations or humans. Combined with the 1-DOF column and 7-DOF arms, H2-D Ultimate achieves a remarkably flexible posture envelope that covers the full vertical workspace from ground to 2 m.

Dual Intel Compute — Power for Control & Development

The H2-D Ultimate K ships with a built-in dual-compute architecture: PC1 runs an Intel Core i5 for real-time platform functionality and motion control, while PC2 provides an Intel Core i7 dedicated to user development. This separation ensures deterministic robot behavior while giving researchers full freedom to experiment. Optional expansion slots (PC3 for NVIDIA Jetson Thor, PC4 for Intel i7 or Jetson Orin NX) future-proof the platform as your AI ambitions grow. A visualization computer is included as standard for monitoring, debugging, and development.

Binocular Vision & AI Perception

A wide-angle humanoid-style binocular camera head delivers a broad field of view for spatial awareness. Paired with an 8-core high-performance CPU + 10 TOPS NPU in the head module, plus the dual Intel compute in the body, it runs visual perception, object detection, and gesture recognition locally — no cloud required. The Senyun SHF3L wrist cameras on each Revo 3 U21T hand deliver wide-angle visual feedback for grasping at 1920×1536 resolution and 30 fps with a 196° horizontal FOV. The compact RRGB sensor with built-in ISP and YUV422 8-bit output operates from −40°C to +85°C and is compatible with NVIDIA Jetson AGX Thor. Combined with the chassis-mounted LiDAR and depth camera, this enables rich multi-modal perception for autonomous navigation and manipulation.

Voice Collaboration & Natural Interaction

Array beamforming microphones and high-power speakers enable clear voice capture and synthesis in noisy industrial floors or warehouses. The open audio framework supports custom wake words, multilingual TTS, and integration with LLMs for conversational command-and-control.

Industrial-Grade. Mobile. 24/7 Ready.

At 1200–1700 × 576 × 620 mm (height adjustable) and approximately 135 kg, the H2-D Ultimate K is a substantial yet mobile industrial workstation. The differential-drive chassis supports autonomous navigation with 360° rotation. The built-in 48V/30Ah battery provides approximately 5 hours of runtime with battery swap and automatic recharge support. An external power supply is also included for stationary wired operation. Note: the upper body cannot accommodate a battery — all power is drawn from the chassis.

 

Biomimetic Design & Full-Body Mobility: a mobile chassis and whole-body coordinated motion extend the operating workspace across entire facilities, enabling flexible manipulation from floor level to 2 m height.
