TrajWAM: An Efficient Trajectory-Guided World Action Model for Dynamic Robotic Manipulation

Dynamic object manipulation requires robots to anticipate target motion while replanning fast enough to avoid executing outdated actions. Existing approaches either rely on fast reactive control without an explicit future target state or encode anticipated motion only implicitly. World Action Models (WAMs) offer a prom...

CAC-VLA: Context-Gated Action Conditioning for Vision-Language-Action Models

CAC-VLA is proposed, a Context-Gated Action Conditioning framework that learns a lightweight latent-action interface directly within the VLM that enables VLM-native action conditioning while calibrating the influence of latent-action guidance on expert action generation.
