Unitree G1: The Humanoid Agent of the Future

The Unitree G1 represents a paradigm shift in robotics—a compact, hyper-mobile Humanoid Agent AI Avatar designed to transition seamlessly from the lab to the real world. Whether it’s performing high-precision industrial assembly, mastering Tai Chi, or navigating extreme arctic environments, the G1 is built to redefine the limits of embodied AI.

Standing at 132 cm and weighing only 35 kg, the G1 combines a portable, foldable frame with the "intelligence" of a world-class AI model, making humanoid technology accessible for researchers, educators, and innovative industries.

Flexibility & Human-Like Motion

The G1 is engineered with flexibility that often exceeds human capability, powered by 23 to 43 high-performance joint motors (depending on the configuration).

• Extraordinary Range of Motion: Features extra-large joint space angles, including a waist rotation of ±155° and knee joints spanning 0–165°, allowing the G1 to perform deep squats, dynamic standing, shake hands, recovering from complex positions with ease.
• Precision Manipulation: Equipped with force-position hybrid controlled hands, the G1 can manipulate objects with extreme sensitivity. From handling delicate eggs and playing cards to lifting 2–3 kg industrial components, its hands simulate the nuance of human touch.

• Performance Tested: The G1 has been battle-tested in televised boxing matches and has demonstrated extreme agility through competitive Tai Chi routines.

AI-Driven Intelligence

Driven by the UnifoLM (Unitree Robot Unified Large Model), the G1 represents a new era of intelligence through imitation and reinforcement learning.

• World-Model Intelligence: The robot doesn't just follow scripts; it understands physical interactions. This allows for continuous learning and adaptation to new, unstructured environments.
• Autonomous Navigation: Equipped with 360° LiDAR and depth cameras, it maps surroundings and avoids obstacles in real-time.
• Interactive Features: Supports voice commands in both English and Chinese, powered by a 4-microphone array and 5W speaker.
• Industrial Utility: Recent deployments (2026) have seen the G1 integrated into factory production lines, using the UnifoLM-X1-0 model to perform precision assembly tasks.

Built for the Future of Work

Beyond the research lab, the G1 is a versatile tool for various industries:

• Manufacturing: Supports assembly, welding, and material handling.
• Logistics: Automates palletization and complex sorting tasks.
• Public Service: Deployed as a high-speed train attendant (Hangzhou, 2026) to assist passengers and patrol carriages.
• Extreme Environments: Proven hardware durability, successfully completing a 130,000-step autonomous trek in temperatures as low as -53°F.
