Unitree H2
The Unitree H2 is a full-size, bionic humanoid robot built for natural, expressive whole-body motion and real-world task execution. With 31 degrees of freedom, high-torque joints, and a high-performance onboard AI compute platform, the H2 targets research, embodied-AI development, human–robot interaction, and advanced demonstration scenarios.
Expressive Whole-Body Motion
The H2 features 31 degrees of freedom, including 6-DOF legs, 7-DOF arms, a 3-DOF waist, and a 2-DOF head. Combined with joint torques up to 360 N·m, this kinematic configuration enables fluid, human-like movement — walking, balancing, gesturing, and dynamic full-body actions.
Onboard Intelligence
A high-performance AI compute platform rated at up to 2070 TOPS supports onboard perception, planning, and multimodal model inference. Paired with a binocular vision system and joint-level sensing, the H2 can perceive its environment and execute perception-driven behaviours in real time.
Practical Payload and Endurance
The H2 carries a 7 kg continuous payload, with short-duration capacity up to 21 kg, supported by a quick-release smart battery for fast swaps during extended operation.
Open Control and Developer-Friendly Design
The H2 exposes fully open, low-latency control interfaces over Unitree’s unitree_sdk2 (C++),
unitree_sdk2_python (Python), and unitree_ros2 packages, communicating via DDS. It is suitable for:
Humanoid locomotion and whole-body control research
Embodied AI and reinforcement learning
Human–robot interaction experiments
Manipulation with optional dexterous hands
Note
For SDK setup, network configuration, and example commands, see the SDK Development section. The official developer reference is maintained by Unitree at the H2 Developer Guide.
