Researchers have introduced BEAR, a new benchmark designed to evaluate and diagnose the skill-level capabilities of embodied multimodal large language models (MLLMs). This benchmark decomposes embodied tasks into 14 distinct atomic skills, providing more granular insights into model failures than previous task-level evaluations. Evaluations on BEAR revealed that perceptual limitations and unstable spatiotemporal modeling are significant bottlenecks for current MLLMs. To address these issues, the team developed BEAR-Agent, a conversational agent that enhances MLLMs with visual and spatial reasoning tools, demonstrating substantial performance improvements on the benchmark and in robotic experiments.
