VRHs are functionally specific, preserving output format while corrupting localization
Errors accumulate without effective correction in MLLM agents during extended urban exploration
Universal physical laws govern spatiotemporal dynamics regardless of the actor
This work represents a first step toward interactive PhysicalGS systems with calibrated Gaussian assets that have consistent rendered appearance and simulated response
A software-hardware co-design approach, where deployment constraints are considered from the start, will make generative AI deployment sustainable and accessible across a much broader range of platforms
