When Should a Robot Think? Resource-Aware Reasoning via Reinforcement Learning for Embodied Robotic Decision-Making

arXiv:2603.16673v4 Announce Type: replace-cross Abstract: Embodied robotic systems increasingly rely on large language model (LLM)-based agents to support high-level reasoning, planning, and decision-making during interactions with the environment. However, invoking LLM reasoning introduces substantial computational latency and resource overhead, which can interrupt action execution and reduce system reliability. Excessive reasoning may delay actions, while insufficient reasoning often leads to incorrect decisions and task failures. This raises a fundamental question for embodied agents: when

Why this matters
Why now

The proliferation of LLMs in embodied AI systems highlights a critical and immediate need to balance sophisticated reasoning with real-time operational efficiency.

Why it’s important

This research directly addresses the practical limitations of integrating advanced AI with robotic autonomy, which is crucial for scalable and reliable deployment in diverse environments.

What changes

The focus is shifting from simply equipping robots with LLMs to dynamically managing when and how those cognitive resources are utilized to optimize performance and responsiveness.
