TL;DR
The paper tackles socially compliant robot navigation by bridging perception to action through language-based reasoning using Vision-Language Models. It introduces the snei dataset (over 40K human-annotated VQA across 2K social scenarios) and a Social-LLaVA model fine-tuned on snei to produce chain-of-thought style language explanations and high-level navigation guidance. Evaluations include qualitative human judgments showing Social-LLaVA outperforming GPT-4V and Gemini on social navigation VQA and a real-world onboard demonstration, highlighting improved explainability and decision-making. These contributions point toward more intuitive, language-grounded, and socially aware robot navigation in unstructured public spaces, while acknowledging limitations and proposing directions for richer data and grounding to action.
Abstract
Most existing social robot navigation techniques either leverage hand-crafted rules or human demonstrations to connect robot perception to socially compliant actions. However, there remains a significant gap in effectively translating perception into socially compliant actions, much like how human reasoning naturally occurs in dynamic environments. Considering the recent success of Vision-Language Models (VLMs), we propose using language to bridge the gap in human-like reasoning between perception and socially aware robot actions. We create a vision-language dataset, Social robot Navigation via Explainable Interactions (SNEI), featuring 40K human-annotated Visual Question Answers (VQAs) based on 2K human-robot social interactions in unstructured, crowded public spaces, spanning perception, prediction, chain-of-thought reasoning, action, and explanation. We fine-tune a VLM, Social-LLaVA, using SNEI to demonstrate the practical application of our dataset. Social-LLaVA outperforms state-of-the-art models like GPT-4V and Gemini, based on the average of fifteen different human-judge scores across 50 VQA. Deployed onboard a mobile robot, Social-LLaVA enables human-like reasoning, marking a promising step toward socially compliant robot navigation in dynamic public spaces through language reasoning.
