H2-A Standard B — upper-body humanoid with Dex3-1 three-finger dexterous hands, 7-DOF arms & dual Intel compute

What's in This Configuration

The H2-A Standard B upgrades the entry-level platform with Dex3-1 Force-Control Three-Finger Dexterous Hands on both arms — delivering true multi-finger manipulation for in-hand reorientation, precision grasping of irregular objects, and dexterous tool use. Each hand features 7 DOF (thumb: 3, index: 2, middle: 2) with force-controlled actuation and an integrated wrist RGB camera. Combined with the dual Intel Core i5/i7 compute architecture, 3-DOF waist, and binocular vision, Standard B is the ideal starting point for labs focused on dexterous manipulation, in-hand manipulation, and advanced grasp planning research.

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

The H2-A Standard B 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 600 mm reach 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 down to ±0.1 mm.

Multimodal Perception & Natural Interaction: Integrating binocular vision with natural language interaction, H2-A enables intuitive and natural human–robot collaboration.

Dex3-1 Three-Finger Dexterous Hands — Force-Controlled Precision

The Dex3-1 is a force-controlled three-finger dexterous hand designed for advanced manipulation research. Each hand packs 7 DOF into a compact 175×88×77 mm footprint: the thumb drives 3 independent joints for versatile opposition, while the index and middle fingers each provide 2 DOF for adaptive grasping. Force control at every joint enables compliant manipulation — the hand can gently hold fragile objects or firmly grip tools without crushing. The integrated wrist RGB camera (1920×1080, 130° DFOV) provides close-up visual feedback for grasp verification and precision alignment. USB communication interface ensures plug-and-play integration with the H2-A control stack.

3-DOF Waist — Expand Your Workspace

The 3-DOF waist joint provides full torso articulation — yaw, pitch, and roll — dramatically expanding the robot's reachable workspace without moving the base. In a seated or standing deployment, the waist allows the robot to turn and manipulate objects on either side, hand objects from one hand to the other across the body, bend forward for floor-level picking, and orient toward humans or workstations. Combined with 7-DOF arms and Dex3-1 dexterous hands, the H2-A achieves human-like reach envelopes that cover a full sphere of workspace — ideal for collaborative tasks, in-hand manipulation studies, and human-robot interaction research.

Dual Intel Compute — Power for Control & Development

The H2-A Standard B 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.

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 Dex3-1 wrist cameras add close-up visual feedback for precision grasping, finger tracking, and manipulation verification.

Voice Collaboration & Natural Interaction

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

Compact. Industrial-Grade. Desk-Ready.

At just 780 × 444 × 200 mm and approximately 34.4 kg (with battery), the H2-A Standard B fits on a reinforced lab bench or industrial workstation. The compact footprint leaves room for objects, tools, and sensors around the robot. Power via the included upper-body Li-ion battery for ~8 hours of untethered operation, or connect the external power supply for 24/7 continuous use.

Comprehensive SDKs and APIs, together with a mature manipulation and perception software stack, enable developers to focus on application innovation while reducing development cycles from months to weeks.

Full-Stack Open Development

Unitree provides a mature, Linux-based robot development framework with open APIs for the underlying system, robotic arms, audio, lighting, and visual control. ROS 2 native support, dual encoders on every arm joint, and hollow internal wiring make the H2-A Standard B a clean slate for reinforcement learning, teleoperation research, and embodied AI. The dual Intel compute handles model training and inference without external hardware.

Upgrade Path — Grow With Your Research

Start with Standard B and expand as your projects evolve. The H2-A platform is fully modular:

• End Effectors — Upgrade from Dex3-1 to Dex3-1 Tactile (33 sensors per hand), Dex5-1 5-finger hands, BrainCo Revo 2/3, Inspire Robots DFQ/E2, LinkerBot Hand O6, WUJI Hand 2, or other tendon-driven hands.
• Wrist Cameras — Already included with Dex3-1. All upgrade hands include wrist RGB cameras for close-up visual feedback and grasp verification.
• Compute Module — Add NVIDIA Jetson Thor (PC3) or Intel Core i7 / Jetson Orin NX (PC4) to unlock massive AI performance for embodied intelligence research.
• Upper-Body Battery — Included as standard equipment. Provides ~8 hours of cord-free operation.
