Unitree H1
Full-Size Humanoid Robot for Research and Development
Contact for pricing
The Unitree H1 is a full-size humanoid robot from Unitree Robotics, standing 180 cm and weighing 47 kg, which held the world record for bipedal running speed at 3.3 m/s (7.4 mph) at launch. Powered by PMSM M107 motors delivering 360 N·m of knee joint torque and 189 N·m/kg peak torque density, the H1 is priced at approximately $90,000 — one of the most affordable full-size humanoids commercially available. It targets research labs, universities, and R&D teams focused on bipedal locomotion, reinforcement learning, and embodied AI.

What Is the Unitree H1?
The Unitree H1 is Unitree Robotics' first full-size universal humanoid robot. At launch, it achieved the world record for bipedal running speed at 3.3 m/s (7.4 mph) with demonstrated potential exceeding 5 m/s. Standing 180 cm and weighing just 47 kg, the H1 combines elite locomotion performance with affordability. The M107 joint motors achieve a peak torque density of 189 N·m/kg, among the highest in the industry. The updated H1-2 variant adds 7 DOF per arm (vs 4 in the base H1), increases arm torque to 120 N·m, and expands ankle articulation, priced at approximately $150,000.
Key Capabilities
- World-record bipedal running speed of 3.3 m/s (7.4 mph) with potential exceeding 5 m/s
- 360 N·m knee joint torque and 189 N·m/kg peak torque density
- 3D LiDAR for 360° spatial mapping plus Intel RealSense D435i depth camera
- Reinforcement learning gait control with terrain adaptation — stairs, slopes, outdoor
- Dynamic recovery from external disturbances via high-bandwidth torque control
- Full ROS2 compatibility — integrates with Gazebo, MoveIt, and Nav2
- 864 Wh quickly-replaceable lithium-ion battery
- 26 total DOF in the base model (H1-2: 27 DOF)
Engineering & Performance
The H1's defining feature is locomotion performance powered by Unitree's M107 joint motors with a peak torque density of 189 N·m/kg — among the highest in humanoid electric actuators. Industrial-grade crossed roller bearings in every joint ensure precision. The lightweight alloy construction achieves 47 kg — substantially lighter than comparable full-size humanoids (Tesla Optimus: 57 kg, Apptronik Apollo: 73 kg). The 3D LiDAR + Intel RealSense D435i combination provides redundant environmental perception. Reinforcement learning locomotion policies are trained in simulation and deployed via a sim-to-real pipeline.
Real-World Use Cases
The H1's primary application is bipedal locomotion research — universities and labs studying gait generation, balance control, and reinforcement learning use the H1 as a hardware validation platform. The H1's vision, LiDAR, and locomotion capabilities make it a capable platform for training and testing general-purpose robotic agents. Industrial inspection is another fit: the H1 can navigate complex terrain, climb stairs, and operate autonomously in factories and infrastructure facilities inaccessible to wheeled robots.
