The Unitree H2 is a full-size humanoid robot unveiled in late 2025 by Chinese manufacturer Unitree Robotics. Standing at 182 cm and weighing roughly 70 kg, it mirrors adult human proportions and targets dynamic locomotion and embodied AI research. Phased deliveries begin Q2 2026.
Mechanical architecture
H2 features 31 degrees of freedom: 6 DoF per leg (12 total), 7 DoF per arm (14 total), 3-DoF waist and 2-DoF head. The chassis combines aircraft-grade aluminum, titanium alloy and high-strength engineering plastics. Joints use low-inertia internal-rotor PMSM motors paired with industrial crossed roller bearings for high stiffness and force-control precision.
Leg joints deliver a peak torque of 360 N·m, enabling backflips, flying kicks and dynamic running. Arm joints peak at 120 N·m, supporting a rated 7 kg continuous payload and up to 15 kg peak per arm.
Compute and perception
The base model uses an Intel Core i5 for foundational control. The EDU variant integrates an Intel Core i7 plus optional NVIDIA Jetson AGX Thor (up to 2070 TOPS), designed for on-device vision-language models and reinforcement-learning policies. Perception relies on a wide-FoV binocular camera and a high-precision IMU; dedicated LiDAR is absent in the base configuration, suggesting a pure-vision strategy similar to Tesla Optimus.
Manipulation and HRI
The base model ships with dummy hands. Functional manipulation requires modular hand add-ons: Unitree Dex1-1 (V1/V3), the three-finger Dex3-1 (7 DoF) or the Inspire RH56DFQ (6 DoF, 12 joints). A bionic head with facial features, beamforming microphone array, high-power speaker, WiFi 6 and Bluetooth 5.2 enable voice interaction and social presence.
Power and market strategy
A quick-release 75.6 V / 15 Ah (0.972 kWh) lithium-ion smart battery delivers roughly 3 hours of runtime. Air cooling, OTA updates. Tiered pricing: $29,900 base (no SDK), ~$40,900 commercial (with warranty), ~$68,900 EDU with full SDK, ROS 2 and Jetson AGX Thor support — the most affordable full-size humanoid on the market.
