Unitree Robotics
Unitree H2 Humanoid Robot
The Unitree H2 is Unitree's full-size humanoid in its standard configuration: 1.82 m (71.7 in) tall, about 70 kg (154 lb), with 31 degrees of freedom, a bionic head with facial features, and industrial-grade crossed roller bearings at every joint output. For teams that want human-scale presence, reach and dynamics without the research loadout of the H2 Edu, this is the entry point.
Key Highlights
- Full size: 1.82 m (71.7 in), about 70 kg (154 lb), 31 degrees of freedom
- High-torque joints: 360 N·m (265 lb-ft) leg, 120 N·m (88.5 lb-ft) arm peak
- Arm payload rated about 7 kg (15.4 lb), peak about 15 kg (33 lb)
- Human-like binocular camera, array microphone, high-power speaker
- About 3 h runtime from a 15 Ah (0.972 kWh) quick-release battery

Good to Know
For operators 18 and up. The H2 powers on and off while suspended from its included wheeled protective stand, and Unitree asks operators to keep at least 2 m (6.6 ft) of clearance from people and obstacles while it moves. It is an indoor, dry-conditions machine, rated 0°C to 40°C (32°F to 104°F) and neither waterproof nor dustproof. Plan facility floor space for the robot, the protective stand and the packaging case.

1.82 m (71.7 in). 70 kg (154 lb). 31 joints.
360 N·m (265 lb-ft) at the leg joint.
A full-size humanoid you can actually buy.
Motion control, not animation.
Thirty-one degrees of freedom, six in each leg, seven in each arm, three at the waist and two in the head, all running low-inertia high-speed internal rotor motors on industrial-grade crossed roller bearings. Unitree keeps shipping new motion control behaviour over the air, so the robot you buy this quarter moves better next quarter.
Torque where a humanoid needs it.
Peak leg joint torque is 360 N·m (265 lb-ft) and peak arm joint torque is 120 N·m (88.5 lb-ft). That is what lets a 70 kg (154 lb) machine catch itself, change direction and hold a loaded arm position instead of sagging out of the pose.
A full-size humanoid, doing full-size things.
1.82 m (71.7 in) and about 70 kg (154 lb) on 31 joints, with 360 N·m (265 lb-ft) peak leg torque and roughly 3 hours from a 15 Ah (0.972 kWh) quick-release battery.
Human scale, in human spaces.
At 1,820 x 456 x 218 mm (71.7 x 18.0 x 8.6 in) the H2 reaches what a person reaches and fits where a person fits, through a standard doorway, along a corridor, up to a workbench. Unitree does not publish a maximum walking speed for the H2, so we do not quote one.
It sees the room and hears you in it.
A humanoid binocular camera with a wide field of view handles vision, and an array microphone plus a high-power speaker handle voice both ways. Wi-Fi 6 and Bluetooth 5.2 are built in. Keep at least 2 m (6.6 ft) of clearance around it while it is moving, which is Unitree's own instruction, not ours.
31 Degrees of Freedom • 360 N·m (265 lb-ft) Leg Torque • 70 kg (154 lb) • About 3 h Runtime • FCC Verified
Compute you can build on.
The standard H2 runs an Intel Core i5 platform PC. The H2 Edu adds a second onboard PC with an Intel Core i7 for your own code, secondary development, dexterous hand support, and an optional high-power computing module such as the NVIDIA Jetson AGX Thor at 2,070 TOPS. Pick the one that matches what your team actually plans to write.

Structure and Motion
- 31 degrees of freedom: 6 per leg, 7 per arm, 3 at the waist, 2 in the head.
- 360 N·m (265 lb-ft) peak leg joint torque and 120 N·m (88.5 lb-ft) peak arm joint torque.
- Low-inertia high-speed internal rotor PMSM joint motors on industrial-grade crossed roller bearings.
- 1,820 x 456 x 218 mm (71.7 x 18.0 x 8.6 in) standing, about 70 kg (154 lb) with battery.
- 1,045 mm (41.1 in) calf plus thigh and 690 mm (27.2 in) forearm plus upper arm, so it reaches like an adult.
Sensing, Compute and Power
- Humanoid binocular camera with a wide field of view.
- Array microphone and high-power speaker for two-way voice interaction.
- Intel Core i5 platform PC on the standard H2. The H2 Edu adds an Intel Core i7 development PC.
- Wi-Fi 6 and Bluetooth 5.2, with intelligent OTA updates.
- 15 Ah (0.972 kWh) quick-release smart battery, about 3 hours. Buy a spare if you are running all day.
Payload and Honest Limits
- Arm payload rated about 7 kg (15.4 lb), peak about 15 kg (33 lb), and it varies with arm extension.
- Rated 0°C to 40°C (32°F to 104°F), and it is not waterproof or dustproof. Indoor, dry conditions.
- Unitree publishes no maximum walking speed for the H2, so neither do we.
- Operators 18 and up, with at least 2 m (6.6 ft) of clearance from people and obstacles while it moves.
- It powers on and off suspended from its wheeled protective stand, so plan floor space for the stand and the packaging case.
Compare the Unitree Humanoids
The H2 and H2 Edu share one chassis. What changes is whether you can write code for it. The G1 Edu Standard is the smaller, cheaper research platform when full human scale is not the point.

FAQs
Is the Unitree H2 authorized for use in the US?
Yes. It is covered by Unitree's US equipment authorization under grantee YuShu Technology Co., Ltd., FCC ID 2A5PE-YUSHU012, verifiable at apps.fcc.gov/oetcf/eas. FCC equipment authorization is separate from NDAA procurement eligibility, so if you are buying under a federal procurement rule, check that separately with us first.
How long does it run on a charge?
About 3 hours on the 15 Ah (0.972 kWh) quick-release smart battery. The pack comes out without tools, so programs running a full day usually buy a spare.
How is the H2 different from the H2 Edu?
Mechanically they are the same robot: 1.82 m (71.7 in), about 70 kg (154 lb), 31 degrees of freedom, the same 360 N·m (265 lb-ft) leg joints. The Edu adds secondary development, a second onboard PC with an Intel Core i7, dexterous hand support and an optional high-power computing module. If your team is not writing its own control code, the standard H2 is the right buy.
How much can the arms carry?
Unitree rates the arm at about 7 kg (15.4 lb) with a peak of about 15 kg (33 lb), and says the figure varies with arm extension. Treat the rated number as the planning figure, not the peak.
Can I run it outdoors?
Only in dry conditions and within 0°C to 40°C (32°F to 104°F). The H2 is neither waterproof nor dustproof, and Unitree tells operators to avoid wet, dusty or low-friction ground. We will tell you when a job is outside what this machine should be doing.
Do you accept purchase orders?
Yes. We work with universities, research institutions and public agencies and accept purchase orders and tax-exempt purchasing. Tell us what your procurement office needs and we will format the quote to match.
