Unitree H1 Review: Specs and Uses of the Full-Size Running Humanoid Robot
Updated: 7 days ago
The Unitree H1 is a full-size humanoid robot about 1.8 m tall that weighs about 47 kg and runs at 3.3 m/s. The manufacturer does not publish a firm price. This review covers its specifications, the H1-2 version, its design and its uses.
Quick Verdict
The H1 made its name with speed: the maker gives 3.3 m/s, which it lists as a record for a full-size humanoid, and says the design could exceed 5 m/s. It is light for its size at about 47 kg, with very strong leg joints and a 3D LiDAR and depth camera for all-round perception. The original H1 has simple arms with four joints each. The H1-2 is a different proposition: heavier at about 70 kg, slower, but with seven joints in each arm and a rated arm load of about 7 kg. Both are research platforms. Prices are given on request.

Design and Build Quality
The H1 has the height of an adult but weighs about 47 kg, well under most full-size humanoids, and its leg joints deliver up to about 360 N·m at the knee. That ratio of torque to weight is what allows it to run. Perception comes from a 3D LiDAR combined with a depth camera, giving depth data all around the robot. The H1-2 adds a sixth joint to each leg, a waist joint and seven-joint arms, and gains about 23 kg in the process. The maker notes that specifications may change and that the shipped product prevails.
Software and Development
Computing
Two computers are fitted as standard, one for the robot's own functions and one for the user's development work, with NVIDIA Orin NX as an option.
Updates
The robot receives software updates over the air.
Unitree H1 Uses
The H1 is used for research into humanoid locomotion and, in the H1-2 version, manipulation.
Locomotion Research
The H1's speed and light weight make it a platform for work on running, balance and recovery.
Manipulation Research
The H1-2, with seven-joint arms and optional hands, suits work on handling tasks.
Demonstration
Both versions are used for public demonstration of humanoid technology.
