Summary

ERQA-Plus is a new diagnostic benchmark designed to evaluate reasoning capabilities in embodied AI, addressing the limitations of existing visual and embodied question answering benchmarks that often lack control over tested reasoning dependencies. This benchmark comprises 1,766 question-answer instances grounded in 711 robot-centric images, structured by a taxonomy covering perceptual, action-centric, social-interaction, navigation-environmental, and contextual commonsense reasoning. Its construction involves a multi-stage pipeline combining taxonomy-guided generation, automatic quality judging, iterative revision, and human assessment to ensure high visual grounding and reasoning quality. Benchmarking representative vision-language and embodied models, including LLaVA-NeXT-8B and Qwen3-VL, revealed that while Qwen3-VL-32B achieved 83.4% overall accuracy and a 61.4 SBERT score, significant weaknesses persist in spatial reasoning, procedural reasoning, event prediction, and intention inference. ERQA-Plus thus offers a fine-grained framework for assessing specific embodied reasoning forms.

Key takeaway

For machine learning engineers developing embodied AI, ERQA-Plus offers a critical tool to move beyond general performance metrics. You should integrate this diagnostic benchmark into your evaluation pipeline to precisely identify specific weaknesses in spatial, procedural, event prediction, and intention inference capabilities. This allows you to prioritize model improvements on these nuanced reasoning forms, rather than relying solely on overall accuracy scores.
