# China Mobile open-sources Open-RAIL engineering base for VLA and WAM robot models > Source: > Published: 2026-09-16 07:03:18+00:00 China Mobile has open-sourced Open-RAIL, an engineering base connecting vision-language-action and world-action-model systems with robot bodies. It combines model inference, real-robot execution, data feedback and model iteration in one workflow. Open-RAIL currently supports four heterogeneous robots and 10 VLA or WAM models. The project says a new model can be integrated with as little as 50 to 100 lines of code, while its hardware-abstraction layer standardizes control, state reading and action execution across robot platforms.
