Researchers have introduced MetaSpace, a novel framework for evaluating the spatial cognition of embodied agents. This system applies metamorphic testing principles, commonly used in software engineering, to automatically generate test cases based on logical rules and physical laws. By encoding these principles in Prolog, MetaSpace identifies failures in spatial cognition by detecting violations of predefined metamorphic relations. In evaluations across three scenarios, MetaSpace detected over 90,000 spatial cognition errors in state-of-the-art multimodal large language model (MLLM)-driven agents, revealing that these agents scored significantly lower than humans on a newly introduced Spatial Cognition (SC) score.
