CheckVLA: Execution-Time Verification with Action-Conditioned World Model for Long-Horizon Mobile Manipulation

Vision-language-action (VLA) policies commonly execute long-horizon mobile manipulation through open-loop action chunks, issuing multiple actions without receiving new high-level visual input. A committed chunk therefore implies how observations should evolve, but accidental deviations can violate this expectation whil...

StreamPI: Streaming Multimodal Temporal Modeling for Vision-Language-Action Models

StreamPI is proposed, a streaming multimodal temporal modeling framework that equips single-frame VLA with temporal reasoning capability without introducing any additional parameters and seamlessly inherits pretrained single-frame weights and supports flexible single-frame and multi-frame inference.
