Unitree H1 is a full-size bipedal humanoid robot developed by Unitree Robotics (Hangzhou, China). The platform is positioned as a general-purpose “universal humanoid” for R&D, pilot deployments, and embodied-AI applications. Official materials highlight 27 degrees of freedom (DoF), 360° depth perception using 3D LiDAR + depth cameras, a moving speed up to 3.3 m/s, and a quickly replaceable 864 Wh battery.

Unitree H1 / H1-2 Humanoid Robot

12 Items

Anthropomorphic form factor

H1 is human-scale (about 180 cm tall) with a published weight near 47 kg on the original model; H1-2 materials list ~70 kg depending on configuration. The chassis maintains two arms, two legs, and a torso with a single waist DoF, enabling locomotion and manipulation in spaces designed for people without major infrastructure changes. 

High-torque actuators

Unitree emphasizes power-dense joint modules, citing peak torque density of ~189 N·m/kg and maximum joint torque up to 360 N·m (leg joint). These figures underpin dynamic walking and fast disturbance recovery. Developer pages also describe the M107 joint motor family used across the platform. 

360° perception

The perception suite combines 3D LiDAR with a stereo/depth camera, affording surround depth sensing for mapping and obstacle avoidance in cluttered indoor environments and corridors. Reseller and integrator pages align with the official description, noting 360° coverage. 

Energy and serviceability

The official spec lists an 864 Wh battery that is quickly replaceable, enabling longer duty cycles by swapping packs between sessions—useful for labs and demonstrations where continuous operation is needed. 

Technology and Specifications

Core specifications (representative)

  • Height / mass: ~180 cm / ~47 kg (H1); H1-2 around 178 cm, higher mass due to revisions. 

  • Degrees of freedom: 27 DoF (arms 7×2, legs 6×2, waist 1), per H1-2 overview. 

  • Mobility: 3.3 m/s moving speed (official), with “potential mobility > 5 m/s” cited in marketing; reseller copy commonly lists ~1.5 m/s walking with higher demonstration speeds. Power: 864 Wh battery, quick-swap design.

  • Perception: 3D LiDAR + depth camera for 360° depth sensing. 

  • Actuation: Max leg-joint torque 360 N·m, max arm-joint torque 120 N·m (H1-2 docs).

Computing, control, and tools

Public materials reference an H1 developer portal/SDK, with documentation on joint limits and safety. Third-party listings also note Wi-Fi/Bluetooth connectivity and support for over-the-air (OTA) updates, plus control via the Unitree Explore app for demonstrations. (Exact compute modules vary by program)

Applications and Use Cases

  • Robotics research & higher education: H1 serves as a testbed for bipedal locomotion, whole-body control, and manipulation, giving labs human-scale hardware without building actuators and frames from scratch. Documentation and integrator pages cite academic deployments and extended demos.

  • Industrial pilot scenarios: With human-scale reach and surround sensing, H1 is evaluated for machine tending, intralogistics assistance, and inspection in controlled environments where flexible, mobile manipulation is advantageous. (Positioning per official and reseller descriptions)

  • Public demos & events: The combination of dynamic gait and quick-swap energy makes H1 suitable for exhibitions, outreach, and proof-of-concepts showcasing embodied AI.

Advantages / Benefits

  1. Human-scale versatility: Height and reach match human work envelopes, reducing the need to modify facilities for trials.

  2. Power-dense actuation: 360 N·m leg torque and 189 N·m/kg torque density support agile motions and robust balance.

  3. 360° perception: LiDAR + depth fusion provides near-field awareness around the robot, aiding navigation in tight spaces.

  4. Operational continuity: 864 Wh quick-swap battery limits downtime during long lab sessions or demonstrations. 

  5. Evolving platform (H1-2): Published torque figures and maintained 27-DoF layout help standardize research while improving component capabilities.

Comparisons (if relevant)

H1 vs. G1 (compact humanoid): G1 is smaller (~132 cm, ~35 kg) with up to 23–43 DoF in EDU variants and a nominal ~2 h runtime; it targets portability and cost (listed US$16k) for labs and competitions. H1 offers full human scale, higher torques, and faster published speeds (up to 3.3 m/s), but is priced higher and sold by quotation. 

H1 vs. R1 (entry-level 2025 model): R1 is a smaller, lighter, budget humanoid (starting near ¥39,900 / ~US$5.6k) intended for education and basic research; H1 remains Unitree’s flagship full-size platform with greater torque and capability. 

Pricing and Availability

Unitree lists H1 as “Contact us for the real price”, and its **shop catalog shows a reference price of about US$90,000 (ex-tax/shipping). Regional resellers echo the RFQ purchasing model and provide lead-time estimates (often 4–6 weeks for orders). Exact pricing, compute packages, and support levels depend on configuration and region. 

FAQ Section

What is Unitree H1?
A full-size humanoid robot with 27 DoF, 360° LiDAR+depth sensing, and high-torque actuators designed for research, demos, and early pilot deployments. 

How does the Unitree H1 work?
H1 combines power-dense joint motors (up to 360 N·m on leg joints) with a 360° perception stack for mapping and obstacle avoidance. A quick-swap 864 Wh battery supports longer sessions. Control and SDK resources are provided via the Unitree developer portal. 

Why is H1 important?
It offers human-scale embodiment with strong torque and surround vision at a price that—while premium—has broadened access to bipedal research and embodied-AI pilots beyond bespoke lab builds.

What are the key specifications?
27 DoF, 3.3 m/s published top speed, 864 Wh quick-swap battery, 360° LiDAR+depth, max leg torque 360 N·m and max arm torque 120 N·m (H1-2). 

Is there a newer version?
Yes—H1-2 keeps the 27-DoF layout while publishing updated torque figures and body size; it is documented on Unitree’s developer site.

Summary

The Unitree H1 is a human-scale, high-torque humanoid aimed at accelerating bipedal locomotion, manipulation, and embodied-AI research. With 27 DoF, 360° LiDAR+depth perception, a quick-swap 864 Wh battery, and published speeds up to 3.3 m/s, H1 offers a balance of performance and accessibility relative to custom lab builds.
