Unitree H1 / H1-2

Every technology keeps a record book, and humanoid robotics wrote much of its early pages around one machine. The Unitree H1, launched in 2023 as Unitree's first full size humanoid, still holds the humanoid running record at 3.3 meters per second, performed the world's first standing backflip by an electrically driven humanoid, and danced before one of the largest television audiences on earth at the 2024 Spring Festival Gala, the machine that converted Unitree's quadruped dominance into humanoid credibility and put Chinese humanoids on the world's screens. The Unitree H1-2 is its refined successor: the same record holding powertrain philosophy with 7 degree of freedom arms, articulated 2 degree of freedom ankles and a dual Intel Core computing architecture, the H1 generation matured from athlete into instrument.

The generation's signature is power density. The H1's 47 kilogram frame carries knee torque around 360 newton meters, hip torque near 220 and one of the highest torque to weight figures in the field at roughly 189 newton meters per kilogram, the margins that make records, backflips and shove recovery possible, delivered through the self developed low inertia joint motors that remain the family bloodline through today's G1 and H2.

Within Unitree's humanoid line, the H1 generation stands as the proven full size research tier, the record holders between the compact standard and the bionic faced flagship. The Unitree H1 and H1-2 for sale, with full specifications, can be explored through this page.

Background

The machine that made Unitree a humanoid company

When the H1 appeared in 2023, Unitree was the world's robot dog company attempting its first biped, and skepticism was reasonable; within months it was unreasonable. The H1 ran 3.3 meters per second, the fastest any full size humanoid had moved, then landed the world's first electric drive humanoid standing backflip, a maneuver previously demonstrated only on hydraulic research machines, and in February 2024 a troupe of H1s in Yangge costume danced the CCTV Spring Festival Gala before an audience in the hundreds of millions, the moment humanoid robots entered mainstream Chinese, and global, consciousness. The records were engineering arguments: electric actuation, done Unitree's way, could out-athlete anything.

From H1 to H1-2

The H1-2 answers what research programs asked of the original: hands worth studying and feet worth standing on. Its arms grow from 5 to 7 degrees of freedom each, expandable further, bringing humanlike manipulation kinematics; its ankles gain 2 degree of freedom articulation for richer ground contact and balance work; and its computing splits across dual Intel Core processors, platform control and user development separated, with an optional NVIDIA Jetson Orin adding AI headroom, the upgrades that turned the sprinter into a laboratory's long term platform.

How does the H1-2 differ from the H1?

Purpose. The H1 is the record machine, the platform whose margins were spent proving what electric humanoids could do, and it remains the reference for high dynamics locomotion research, the gait, recovery and athletic control work its torque density invites. The H1-2 reallocates the same pedigree toward completeness: seven jointed arms make it a genuine manipulation research platform, articulated ankles deepen its balance and terrain repertoire, the dual CPU split gives user code its own processor, and dual batteries with dual fast chargers in the box acknowledge how laboratories actually run sessions. Programs chasing dynamics still choose the H1's lineage; programs building whole body autonomy choose the H1-2, and the field's literature now carries both.

Technology

The powertrain that set the records

Both machines run Unitree's self developed low inertia, high torque density joint motors, the 360 newton meter knees and 220 newton meter hips that carried the H1 to its sprint record and through its backflip, engineering since inherited across the family and proven, in the H1 generation, at the extremes that make ordinary operation trivial.

Learning trained dynamics

The generation's athletics come from reinforcement learning trained control transferred from simulation, the shove recoveries, dynamic gaits and record runs that established Unitree's sim to real pipeline as the field's benchmark, with capabilities continuing to improve through OTA updates across the installed base.

Perception and development stack

3D LiDAR fused with depth camera vision gives both machines full environmental sensing for navigation and manipulation research, while the H1-2's dual Intel Core architecture, one processor for platform control, one for user development, plus its optional Jetson Orin, hosts the custom stacks research exists to write, within Unitree's SDK, ROS support and the support and accessories ecosystem of batteries, chargers, controllers and gantries.

Sessions built to continue

The H1-2 ships session ready: dual 15 amp hour, 0.864 kilowatt hour batteries and dual fast chargers standard, the rotation hardware included rather than optioned, a small specification that reads like what it is, a platform designed by people who watch laboratories work.

What are the Unitree H1 and H1-2 used for?

1. High dynamics locomotion research: the record holder's home ground across research robotics, gait, recovery and athletic control at full human scale.
2. Whole body autonomy and manipulation: the H1-2's seven jointed arms and articulated ankles serving integrated perception, locomotion and manipulation programs.
3. Enterprise humanoid R&D: full size platform development before deployment scale commitments, the proving tier beneath industrial and warehouse humanoid ambitions.
4. Advanced education: flagship hardware for graduate programs across educational robotics, the machines the textbook milestones happened on.
5. Demonstrations and heritage bookings: the Gala generation's presence at exhibitions and events, records that audiences still recognize on sight, within the wider bipedal humanoid canon.

Frequently Asked Questions

What are the Unitree H1 and H1-2?

The H1 is Unitree's first full size humanoid, the roughly 180 centimeter, 47 kilogram record holder for humanoid running speed at 3.3 meters per second and the first electric drive humanoid to land a standing backflip; the H1-2 is its upgraded successor with 7 degree of freedom arms, 2 degree of freedom ankles and dual Intel Core computing.

How do the Unitree H1 and H1-2 work?

Both run reinforcement learning trained whole body control on Unitree's high torque density joint motors, roughly 360 newton meters at the knee and 220 at the hip, perceiving through 3D LiDAR and depth camera fusion, with the H1-2 adding a dedicated user development processor, optional Jetson Orin AI compute and dual battery, dual charger session hardware as standard.

Why is the Unitree H1 important?

It supplied humanoid robotics' proof era: the speed record, the first electric backflip and the Spring Festival Gala performance that introduced humanoids to a mainstream audience of hundreds of millions, the demonstrations that established electric actuation, and Unitree, at the category's front, and whose engineering every later family member inherits.

What are the benefits of the Unitree H1 and H1-2?

Key benefits include the field's proven extreme performance margins, roughly 189 newton meters per kilogram of torque density, record validated learning based control, full environmental sensing, the H1-2's manipulation grade arms and development architecture, included session power hardware and membership in Unitree's ecosystem and literature.

What is the difference between the H1 and H1-2?
