CT-SAFR: Safe and Interpretable Chain-of-Thought Reasoning for Autonomous Robots: A Multi-Layered Verification Framework for Trustworthy AI-Driven Robotic Decision Making

AI reasoning systems often don't show their work honestly: The paper found that large language models only verbalize their actual decision-making process 25-39% of the time, meaning robots relying on these systems may be following reasoning paths that aren't transparent to human operators—a critical concern for safety-critical applications.

Complexity breaks transparency: When tasks become more complex, the faithfulness of AI reasoning degrades by 44%, suggesting that autonomous robots handling complicated warehouse operations or other intricate scenarios face heightened risks of unreliable decision-making that appears justified but isn't.

Multi-layered verification significantly improves safety: CT-SAFR's framework achieved 94.2% accuracy in detecting when AI systems are "hallucinating" or making unfounded claims, while maintaining fast response times (under 500 milliseconds), demonstrating that practical safety mechanisms can be built into robotic systems without sacrificing speed.

Real-world impact is measurable: In a warehouse robot case study, the verification framework reduced unsafe reasoning outputs by 87% with statistical significance (p < 0.001), providing concrete evidence that responsible AI practices can meaningfully improve autonomous robot safety in actual operational settings.

Responsible deployment requires verification layers: The paper's recommendations emphasize that organizations deploying reasoning-capable robots shouldn't rely solely on the AI system's explanations; instead, they need independent verification mechanisms to catch errors before robots make consequential decisions.
