Chinese humanoid robot maker EngineAI announced an embodied-AI ecosystem program called Engine Plan, opening its humanoid robot SDK to global developers and partners while pursuing open co-building of foundation models, datasets and toolchains. According to DoNews, the plan offers both a lightweight fast-development SDK channel and deep-customization access with low-level interfaces and deployment code, plus simulation assets; on the model side it plans to gradually open its self-developed motion-control framework and embodied model weights covering motion control, perception and decision-making. EngineAI also said it will release thousand-hour first-person (ego) and ten-hour real-robot datasets in Q4 2026. The report notes EngineAI shipped about 400 units in 2025 versus 5,168 for AgiBot and over 5,500 for Unitree, per Omdia data cited in Unitree's prospectus, and that its 2026 annual framework orders exceeded RMB 500 million as of January, though framework orders are not equivalent to revenue.
