Ultimate AI Compute with Force-Control Dexterous Manipulation

Unitree Robotics presents the H2 Plus Ultimate-B — a full-size 182 cm humanoid robot combining flagship onboard AI computing with advanced force-control dexterous manipulation. As part of the H2 Plus Ultimate series, this configuration is engineered for demanding research in embodied AI, robotic grasping, manipulation and human–robot interaction.

Built on the H2 Plus Smart platform, the Ultimate-B integrates two Dex3-1 Force-Control Three-Finger Dexterous Hands without tactile feedback. Each hand provides 7 degrees of freedom, with 3 DOF in the thumb and 2 DOF in both the index and middle fingers, enabling precise and controlled interaction with objects.

What's in This Configuration

Dex3-1 — Three-Finger Force-Control Manipulation

Each Dex3-1 hand combines three-finger articulation with 7 degrees of freedom: 3 in the thumb, 2 in the index finger and 2 in the middle finger. This layout supports controlled pinch, grasp and object interaction while keeping the hand compact and mechanically focused.

The force-control capability enables precise and delicate object handling for research in grasping, manipulation and haptics. Each hand weighs approximately 650 g and measures 175 × 88 × 77 mm.

Flexible Power and USB Communication

The Dex3-1 hand operates across a voltage range of 12–58 V and uses a USB communication interface. Static current is specified at 58 V and 0.2 A, supporting practical integration with the H2 Plus Ultimate-B platform.

Wrist-Mounted RGB Cameras for Close-Range Perception

Each hand includes a wrist-mounted RGB camera with 1920 × 1080 resolution and a diagonal field of view of 130°. These cameras provide detailed visual feedback near the end effectors during fine manipulation and grasp verification.

45 Degrees of Freedom — Coordinated Whole-Body Motion

The H2 Plus Ultimate-B provides 45 total degrees of freedom: 6 per leg, 7 per arm, 3 at the waist, 2 at the head and 7 in each dexterous hand. This configuration combines dynamic whole-body motion with precise three-finger force-control manipulation.

NVIDIA Jetson Thor — Ultimate Onboard AI Compute

The standard PC3 computing module is an NVIDIA Jetson Thor delivering 2070 TFLOPS of FP4 sparse AI performance. Its 2560-core NVIDIA Blackwell architecture GPU with 5th Generation Tensor Cores is paired with a 14-core Arm Neoverse-V3AE 64-bit CPU operating at 2.6 GHz and 128 GB of LPDDR5X memory with 273 GB/s bandwidth.

The robot also includes an Intel Core i5 processor for platform functionality and an Intel Core i7 processor for user development. An empty PC4 slot is reserved for an optional Intel Core i7 module selected at the time of purchase.

High-Torque Joints. Industrial-Grade Precision.

Low-inertia, high-speed inner-rotor permanent magnet synchronous motors provide up to 120 N·m of torque in the arm joints and up to 360 N·m in the leg joints. Industrial-grade cross-roller bearings support high precision and load capacity, while the arms provide an approximate rated payload of 7 kg and a peak payload of approximately 15 kg.

Aerospace-Grade Construction & Quick-Swap Power

The robot is constructed from aerospace-grade aluminum, titanium alloy and high-strength engineering plastics. It weighs approximately 70 kg with battery and uses an air-cooled thermal design. The 15 Ah, 0.972 kWh smart battery operates at up to 75.6 V and provides approximately 3 hours of runtime. Its quick-release design supports practical battery replacement during research and testing.

Stereo Vision & Natural Human–Robot Interaction

A bionic head and face are combined with wide-field-of-view humanoid stereo cameras covering 140° horizontally and 102° vertically. Array microphones and high-power speakers support voice interaction and natural human–robot communication.

Connectivity, Interfaces & Open Development

The H2 Plus Ultimate-B supports Wi-Fi 6, Bluetooth 5.2 and smart OTA updates. External interfaces include USB 3.0, USB-DP, GMSL, Gigabit Ethernet, USB 2.0, RS485, CAN and dedicated 12 V, 24 V and battery power outputs.

Full secondary development is supported through open APIs and an SDK compatible with ROS2, Python and C++. Deep system access allows researchers to build custom perception, force-control, manipulation and embodied AI workflows directly on the platform.
