Unitree H1: Unitree's First General-Purpose Humanoid Robot 128

Unitree Robotics's Unitree H1 is a full-size general-purpose humanoid robot, and the first general-purpose humanoid robot launched by Unitree Robotics. With its high-performance hardware, self-developed core components, and intelligent algorithms, it has become a benchmark product in the global humanoid robot field.

I. Core Hardware and Performance Parameters

Lightweight Design and High Degrees of Freedom

The Unitree H1 stands approximately 1.8 meters tall, weighs only 47 kilograms, and features 19 degrees of freedom across its body (10 in the legs, 1 in the waist, and 8 in the arms), enabling it to simulate complex human movements such as walking, turning, and grasping. Its leg joints use lightweight material design, achieving a walking speed of 1.5 meters per second, with potential mobility capability that can be enhanced up to 5 meters per second—approaching the speed of a human jogging.

Self-Developed Joint Motors

Key joints (such as the knee, hip, and ankle joints) are equipped with Unitree's self-developed M107 high-density motors. The knee joint delivers a peak torque of 360 N·m, the hip joint 220 N·m, the ankle joint 45 N·m, and the arm joints 75 N·m. This design addresses the shortcomings of traditional servo motors in terms of volume, power, and density, achieving a combination of high explosive force and precise control.

Battery Life and Perception System

It has a built-in 15Ah battery with a maximum voltage of 67.2V, supporting 1 hour of continuous dynamic movement. Equipped with 3D LiDAR and depth cameras, it achieves 360° panoramic depth perception, and combined with TOF technology, generates 3D point cloud information to enhance obstacle avoidance and navigation capabilities in complex environments.

II. Technical Highlights and Functional Breakthroughs

Dynamic Motion Control and AI Algorithms

Backflip and Balance Capabilities: The Unitree H1 is the world's first full-size motor-driven humanoid robot to perform a standing backflip. Its dynamic balance algorithm can adjust the center of gravity in real time, ensuring movement stability.

Cluster Collaboration and Positioning: Through 3D LiDAR SLAM technology and synchronized networking solutions, multiple Unitree H1 robots can achieve millisecond-level coordination on stage. For example, during the 2025 CCTV Spring Festival Gala's "Yong BOT" performance, 16 H1 robots completed high-precision formation changes and handkerchief tossing and catching movements.

Dexterous Manipulation and Multi-Scenario Adaptability

The Unitree H1 can be optionally equipped with a three-finger dexterous hand, supporting fine operations such as opening bottle caps and grasping objects. Its modular design allows users to customize sensors or tools, extending to scenarios such as industrial inspection and home services.

Perception and Interaction Capabilities

It integrates large AI models to enhance natural language processing and semantic understanding capabilities, combined with depth cameras to enable environmental interaction. For example, during the 2025 CCTV Spring Festival Gala's "Yong BOT" performance, the Unitree H1 achieved perfect synchronization with the music through dance rhythm alignment algorithms, demonstrating the fusion of art and technology.

III. Practical Applications and Industry Impact

Breakthroughs in Cultural Performance

At the 2025 CCTV Spring Festival Gala, the Unitree H1 wore traditional costumes, holding red silk handkerchiefs to perform the Yangge dance "Yong BOT." The H1 can design movements based on dance requirements and execute them through AI training, demonstrating a high degree of flexibility and coordination.

Industrial and Scientific Research Applications

The Unitree H1 has been applied in fields such as university scientific research and factory inspection. Its high load capacity (such as 20 kg leg load-bearing) and complex terrain adaptability (such as climbing 40 cm steps) surpass competitors like Boston Dynamics' Spot.

Market Positioning and Commercialization

The launch of the Unitree H1 marks China's humanoid robot technology ranking among the global forefront. Despite its relatively high price (approximately 90,000 USD), the subsequent release of the G1 model (starting at 99,000 RMB) by Unitree further lowered the commercialization threshold, promoting the penetration of humanoid robots into scenarios such as home services and medical care.
