Unitree Humanoid Accessories

Dexterous Hand Accessories

Unitree offers three dexterous hand families as optional accessories for its humanoid robot platforms, each targeting a different point on the dexterity-versus-simplicity spectrum.

Dex1-1: Two-Finger Force-Controlled Gripper

The Dex1-1 is Unitree's simplest manipulation end-effector — a parallel-jaw two-finger gripper with force-position hybrid control. It is the standard end-effector for the G1-D Standard A (U1) configuration and is available separately for other platforms. The Dex1-1 covers the pick-and-place tasks that represent the majority of logistics and light industrial manipulation use cases: cylindrical objects, boxes, bags, and standardized components within the jaw's opening range. Its lower mechanical complexity relative to the three-finger and five-finger systems makes it the most reliable and lowest-maintenance option for high-cycle industrial applications.

Dex3-1: Three-Finger Dexterous Hand

The Dex3-1 is Unitree's proprietary three-finger dexterous hand, providing 7 active degrees of freedom per hand (thumb: 3 DOF, index: 2 DOF, middle: 2 DOF) under force-position hybrid control. It is available in two tactile configurations:

Dex3-1 without tactile sensors: Included in the G1 EDU Ultimate A (U3) at approximately $64,292 and available separately. Covers power grasps, precision pinch, tripod grasps, and lateral key grips without distributed contact sensing.

Dex3-1 with tactile sensors: Included in the G1 EDU Ultimate B (U4) at approximately $66,277 and available separately. Adds distributed tactile pressure arrays to the same three-finger kinematic system, enabling grasp quality assessment, slip detection, and force regulation for fragile objects. Confirmed by Top3DShop as the defining difference between the U3 ($64,292) and U4 ($66,277) configurations — a $1,985 premium for the tactile sensing upgrade.

Dex5-1 / Dex5-1P: Five-Finger Tactile Hands for H1/H1-2

The Dex5-1 (left) and Dex5-1P (right) are Unitree's most capable manipulation end-effectors — five-finger dexterous hands with 20 total degrees of freedom, 94 tactile pressure sensors per hand, and 1,000 Hz real-time feedback. Designed specifically for the H1 and H1-2 full-size humanoid robots, they are the official optional hands listed on Unitree's H1 product page as "Optional Dex5-1 or other ambidextrous hands."

Confirmed specifications from RobotShop and OpenELAB:

• 20 DOF (16 active + 4 passive)
• 94 tactile sensors detecting 10g to 2.5 kg
• 1,000 Hz communication rate
• Full backdrivability (no "stiff hand" effect)
• ±22° four-finger lateral swing
• ±1 mm fingertip repeat accuracy
• ~1,000 g per hand
• 3.5 kg payload (palm down) / 4.5 kg (palm left)
• Compatible with: H1, H1-2, H2 (some configurations)

AI Compute Expansion Modules

Jetson Orin NX Modules (Internal)

The H1 and H1-2 support up to two NVIDIA Jetson Orin NX modules installed internally, each providing 100 TOPS of GPU-accelerated AI compute. At full internal installation, the system provides 200 TOPS from the dual internal modules. These internal modules are the first compute upgrade tier — they are installed within the robot's chassis and do not require external mounting.

AGX Module for H1 — 275 TOPS

The AGX-H1-275 is an external compute expansion module providing 275 TOPS of AI compute from a single NVIDIA Jetson AGX unit, mounting externally on the back of the H1, H1-2, or B2. When combined with the full internal dual Orin NX configuration, total system AI compute reaches approximately 475 TOPS.

AGX Module for H1 — 550 TOPS

The AGX-H1-550 is the maximum available compute expansion module, providing 550 TOPS from dual NVIDIA Jetson AGX units externally mounted on the robot's back. Combined with the internal dual Orin NX, total system AI compute reaches 750 TOPS — one of the highest on-device AI compute densities available on any commercially purchased humanoid robot.

Battery and Power Accessories

Unitree H2 Battery

The Unitree H2 Battery is a single replacement/spare battery unit for the H2 humanoid robot. The H2's quick-swappable battery design enables a depleted battery to be exchanged in under 30 seconds, enabling sustained all-day research sessions with a battery rotation schedule.

G1 Battery System

The G1 EDU family uses a 9,000 mAh 13-series lithium battery with quick-release mechanism providing approximately 2 hours of runtime per charge cycle. Spare batteries are available through Unitree's authorized distribution network for research teams that need multiple cycles per day.

H1 Battery Pack

The H1's standard battery is a 15,000 mAh (432 Wh) lithium pack providing approximately 1 to 2 hours of operational runtime. Top3DShop documents: "2× 15,000 mAh (432 Wh) lithium battery packs with BMS" included with the H1 purchase. Spare packs are available through authorized channels for research labs running extended sessions.

Development and Safety Equipment

H1 Gantry Stand

The Unitree H1 Gantry is a wheeled protective frame designed for safe H1 development, testing, and debugging — preventing the robot from falling and causing injury or hardware damage during risky software development operations. Unitree's safety documentation makes the gantry strongly recommended: "Mandatory protective gantry for startup/shutdown and risky operations."

Top3DShop documents the specific safety protocols the gantry supports: "Mode hierarchy: Zero Torque, Damping (soft e-stop), Debug (blocks motion control during dev). L1+A triggers immediate switch to Damping."

Teleoperation and Remote Control Systems

Handheld Controller: Included with G1-D Standard purchases, the handheld remote control provides basic robot control for operator-commanded tasks.

VR Teleoperation (Vision Pro / XR): Top3DShop documents: "The H1 offers a full development ecosystem — simulation (MuJoCo, Isaac Lab), teleoperation (XR, Azure Kinect)." VR teleoperation enables human demonstration collection for imitation learning — the human operator uses a VR headset and hand tracking to demonstrate manipulation tasks that are recorded as training data for AI policies.

Azure Kinect Integration: Microsoft Azure Kinect depth cameras are used in H1 teleoperation setups for whole-body human pose estimation — tracking the teleoperator's full body pose to command the robot's corresponding whole-body configuration.

Unitree B2 Navigation Kit (Basic)

The B2 Navigation Kit (Basic) provides autonomous navigation capability for the B2 quadruped robot.

Applications and Use Cases for the Accessory Ecosystem

Building a Full Manipulation Research Platform

The typical research build-out sequence for an H1-2 manipulation research program:

1. Base H1-2 platform: Locomotion + 7-DOF arms 
2. Add Dex5-1 + Dex5-1P bilateral pair: Five-finger tactile manipulation (contact distributors for pricing)
3. Add dual Jetson Orin NX: 200 TOPS internal AI compute 
4. Optionally add AGX-H1-275 or AGX-H1-550: 475–750 TOPS total for large VLA model deployment
5. Add H1 gantry: Required for safe locomotion and manipulation algorithm development

G1 EDU Manipulation Tier Selection

For the G1 EDU lineup, the hand selection determines the entire configuration tier pricing:

Maximum Compute Research Configuration

Research teams deploying the H1-2 for large-scale VLA model inference can build the maximum 750-TOPS configuration:

• H1-2 base with dual Intel Core CPU
• 2× internal Jetson Orin NX: +200 TOPS 
• AGX-H1-550 external: +550 TOPS 
• Total: ~750 TOPS, 30 cores, 36 threads, 72 GB RAM

Advantages of the Modular Accessory Ecosystem

Progressive Investment: The modular design allows research teams to start with a base platform and add capabilities as research programs mature — beginning with locomotion, adding dexterous hands when manipulation research begins, and expanding compute when AI model complexity demands it.

Shared Infrastructure Across Platforms: The AGX modules are compatible with H1, H1-2, and B2, enabling shared compute infrastructure across a multi-robot lab. A lab running both an H1-2 and a B2 can use the same AGX module for different experiments.

Transparent Upgrade Path: The published pricing for each accessory tier enables research programs to budget for the full system build-out at grant proposal stage, not just the base hardware cost — important for federal grant budget justifications.

Standard Mounting Interfaces: All dexterous hands use the same wrist interface design within compatible platform families, enabling end-effector swaps between task configurations without structural modification.
