Long-WAM: Scaling the Context of World-Action Models

Wei Huang, Bohan Zhang, Chenzhi Liu et al. · 2026

Real-time robot control demands enough visual history to infer motion and task progress, but processing that history can delay action. We present Long-WAM, a model-system framework for scaling the context of causal world-action models under real-time control constraints. Our central finding is that access to history is …

ASENA: Self-evolving Agents for Embodied Navigation

We present ASENA, an embodied agent system that connects general-purpose coding agents to robot sensing, computation, supervised execution, and persistent experience. Agents can write and execute programs, inspect recorded outcomes, repair failures, and reuse notes and executable skills while keeping their model weight …
