This paper introduces AstraNav-World, a novel end-to-end world model for embodied navigation. The key innovation lies in its unified probabilistic framework that jointly reasons about future visual states and action sequences. This approach, integrating a diffusion-based video generator with a vision-language policy, aims to improve trajectory accuracy and success rates in dynamic environments. The paper's significance lies in its potential to create more reliable and general-purpose embodied agents by addressing the limitations of decoupled 'envision-then-plan' pipelines and demonstrating strong zero-shot capabilities.
