Unitree H2 EDU SMART K Humanoid Robot

Overview

The Unitree H2 EDU SMART K is a full-size humanoid research and development platform from Unitree Robotics, supplied in the H2 EDU Smart Series configuration. Standing approximately 182 cm tall and weighing about 70 kg with its battery, the H2 EDU SMART K is built on the H2 EDU Standard platform and adds a pair of BrainCo Revo 3 U21T dexterous hands with full-palm tactile feedback and wrist-mounted RGB cameras. The result is a research-grade humanoid with 73 total degrees of freedom as configured, combining a highly articulated bipedal body with two 21-DOF tactile hands intended for advanced manipulation research, imitation learning, and embodied AI development.

The platform is aimed at universities, research laboratories, and advanced development teams. It supports secondary development, over-the-air (OTA) software updates, and optional high-performance computing expansion modules, making it suitable for long-term research programs in locomotion, dexterous manipulation, and human-robot interaction. Configuration options and final pricing should be confirmed during quotation or purchase.

Dexterous Hands and Tactile Feedback

The defining feature of the Smart K configuration is its dual BrainCo Revo 3 U21T dexterous hands. Each hand provides 21 active degrees of freedom: the index, middle, ring, and little fingers each have 4 DOF, while the thumb has 5 DOF. This articulation allows the hand to perform complex in-hand manipulation, multi-finger grasps, and fine pinch operations that simpler grippers cannot replicate.

Key hand performance figures from the source specification include:

• Fingertip pinch force of 20 N
• Full-palm grip force of 70 N
• Maximum opening and closing speed of 3 Hz
• Control frequency of 500 Hz
• Full-palm tactile resolution of 0.01 N
• Wide operating voltage range of 12–80 V

The 0.01 N full-palm tactile resolution enables the hands to sense subtle contact forces across the palm surface, supporting research into force-aware grasping, slip detection, and delicate object handling. Each wrist also carries an RGB camera with 1920 x 1080 resolution and a wide field of view (approximately 130 degrees diagonal, 120 degrees horizontal, and 81 degrees vertical), giving vision models a close-range view of manipulation tasks directly from the hand's perspective.

Motion and Body Platform

The H2 EDU body platform provides a humanoid form factor with standing dimensions of 1820 x 456 x 218 mm. The limb layout includes 6 degrees of freedom per leg, 7 per arm, 3 in the waist, and 2 in the head, together with a bionic head and facial features. In the Smart K configuration, the source lists a combined total of 73 degrees of freedom including both dexterous hands.

Joints use industrial-grade cross-roller bearings paired with low-inertia, high-speed inner-rotor permanent magnet synchronous motors. Maximum joint torque reaches 120 N·m in the arms and 360 N·m in the legs, and each arm is rated for a payload of approximately 7 kg, with a peak of approximately 15 kg. The structure combines aerospace-grade aluminum, titanium alloy, and high-strength engineering plastics, with local air cooling for thermal management.

Power comes from a quick-release smart lithium battery rated at 15 Ah / 0.972 kWh with a maximum voltage of 75.6 V, providing approximately 3 hours of operation depending on workload. A charger and a handheld remote controller are included, along with a protective bracket supplied by default.

Compute and Development

The H2 EDU SMART K ships with a dual-computer architecture: PC1, an Intel Core i5 system dedicated to platform-level control, and PC2, an Intel Core i7 system reserved for user development. This separation lets researchers deploy custom software without interfering with core locomotion and stability functions.

For workloads that demand additional AI computing, two optional expansion modules are available: PC3, an optional NVIDIA Jetson Thor module, and PC4, an optional Intel Core i7 or NVIDIA Jetson Orin NX module. These modules must be selected at the time of purchase and cannot be added later, so teams planning on-board deep learning inference should specify them during quotation. The platform supports secondary development and receives smart OTA updates.

Perception and Interaction

Perception hardware includes wide-field-of-view humanoid binocular cameras in the head, the two wrist RGB cameras, and the tactile sensor arrays in the hands. For voice interaction, the robot carries array microphones and high-power speakers. Connectivity is provided by Wi-Fi 6 and Bluetooth 5.2, supporting wireless development workflows, telemetry, and data collection.

Applications

As a specialized research platform, the H2 EDU SMART K is suited to:

• Dexterous manipulation research using tactile-rich, high-DOF hands
• Imitation learning and teleoperation data collection with wrist-camera visual feedback
• Embodied AI and vision-language-action model development on optional GPU modules
• Bipedal locomotion, whole-body control, and human-robot interaction studies
• University robotics curricula and advanced laboratory demonstrations

Technical Specifications

Safety and Configuration Notes

The H2 EDU SMART K is a specialized research platform intended for civilian research and development use. The manufacturer advises that humanoid robots have complex structures and powerful actuation: operators should maintain a sufficient safe distance during operation, read the secondary development manual and warranty documentation before use, avoid dangerous modifications or hazardous use, and comply with local laws and regulations. Parameters may vary by scenario and configuration, some sample functions may still be in development or testing, and the humanoid robotics industry remains in an early exploration phase, so users should understand the platform's current limitations.

Optional PC3 and PC4 computing modules must be selected at the time of purchase and cannot be retrofitted later. The unit is supplied in original manufacturer packaging with a 12-month warranty. Final configuration and pricing should be confirmed during quotation.

FAQ

What distinguishes the Smart K configuration from the H2 EDU Standard?

Smart K is based on the H2 EDU Standard and includes all of its features, adding two BrainCo Revo 3 U21T dexterous hands with tactile feedback and wrist RGB cameras, bringing the configured total to 73 degrees of freedom.

How sensitive are the tactile hands?

Each hand provides full-palm tactile sensing with 0.01 N resolution, 20 N fingertip pinch force, 70 N full-palm grip force, and a 500 Hz control frequency.

Can I add the NVIDIA Jetson Thor or Orin NX modules later?

No. The optional PC3 (NVIDIA Jetson Thor) and PC4 (Intel Core i7 or NVIDIA Jetson Orin NX) modules must be selected at the time of purchase and cannot be added afterwards.

Does the robot support custom software development?

Yes. Secondary development is supported, with a dedicated Intel Core i7 development computer (PC2) separate from the Intel Core i5 platform computer (PC1), plus smart OTA updates.

How long does the battery last?

The quick-release smart battery is rated at 15 Ah / 0.972 kWh (max 75.6 V) and provides approximately 3 hours of operation depending on usage.
