Why it matters

1Founded in October 2023 by Zhao Tongyang, Engine AI rapidly established itself in the humanoid robotics sector.
2By July 2025, Engine AI successfully concluded its Pre-A++ and A1 funding rounds, raising nearly RMB 1 billion.
3The company globally debuted its T800 heavy-duty, full-sized humanoid robot at the World Robot Conference 2025 and showcased it at CES 2026.
4In June 2025, Engine AI released comprehensive open-source resources, including the EngineAI RL Workspace and EngineAI ROS, to foster robotics development.

Stork’s verdict on Engine AI

Engine AI delivers mass-produced lifelike humanoids with advanced AI, but its complexity makes it overkill for most small-scale projects.

Figure AIOn StorkCompare

Figure AI focuses on developing a general-purpose humanoid robot capable of performing diverse tasks in human environments, including household assistance.

Figure AI's Figure 02/03, like Engine AI's offerings, are advanced AI-powered humanoids, but Figure AI emphasizes general-purpose utility and home environments, whereas Engine AI has a stronger stated focus on public service and commercial spaces.

4
Unitree RoboticsOn StorkCompare

Unitree Robotics offers a range of humanoid and quadruped robots known for their agility and performance, targeting research, education, and industrial applications.

Unitree, like Engine AI, is a significant player in humanoid robot shipments, offering industrial-grade humanoids, but Unitree also has a strong presence in the research and education sectors.

5
SoftBank Robotics (Pepper)↗

SoftBank Robotics' Pepper is a widely deployed humanoid robot specifically designed for customer service and interaction in retail and public environments.

Pepper directly competes with Engine AI in the public service and shopping mall sectors by providing customer-facing interactions, though Pepper's design is less focused on 'lifelike walking' and more on communication and interaction compared to Engine AI's bipedal robots.
