Summary:

 

Moz1 is a full-sized humanoid robot developed by Spirit AI (万境千寻科技有限公司), launched in 2025. It features 26 degrees of freedom, biomimetic force-controlled actuators, and a proprietary VLA (Vision-Language-Action) AI model. Designed for real-world task execution, Moz1 can fold laundry, sort office supplies, and respond to natural language commands. With over ¥600 million (~$82M USD) in funding, it’s one of China’s most ambitious entries in the humanoid robotics race.

 

Editorial:

 

Moz1 is Spirit AI’s flagship humanoid robot, engineered for embodied intelligence in everyday environments. Its force-controlled joints and high-torque actuators enable compliant, human-safe motion, while its VLA Spirit v1 model fuses vision, language, and action into a unified control stack. Moz1 can interpret verbal instructions, plan multi-step tasks, and execute them with dexterity—demonstrated in public demos where it folds clothes, organizes desks, and interacts with humans in natural language.

 

The robot’s multimodal sensor suite includes vision, audio, and tactile inputs, allowing it to adapt to dynamic environments. Moz1 supports reinforcement learning, imitation learning, and LLM-based planning, making it a powerful platform for real-world AI research and service robotics. Spirit AI positions Moz1 as a direct competitor to Figure 01 and Tesla Optimus, with a focus on task fluency, expressive motion, and developer integration.
