Researchers have introduced Spa-Bench, a real-robot benchmark for evaluating spatial grounding in vision-language-action models. Results across tested policies show performance drops when robots face out-of-distribution spatial configurations compared to familiar setups, highlighting a key weakness in current systems. The benchmark, described in a new arXiv paper in robotics, gives the field a standardised way to measure how well robot policies understand spatial relationships.

Why now: The robotics community is examining new benchmarks as vision-language-action models rapidly improve and their real-world limitations become a focus.
