Robot Metacognition: Decision Making with Confidence for Tool Invention
🤖 AI Summary
Current robots lack human-like metacognitive capabilities, hindering their ability to assess the reliability of their own decisions and thereby limiting robustness and adaptability in physical environments. This paper proposes an embodied metacognition framework that, for the first time, systematically integrates neuroscience-inspired confidence estimation into the robot’s closed-loop decision-making process, enabling real-time monitoring and self-reflection during action execution. The framework unifies confidence modeling, dynamic decision modulation, and agent–environment interaction mechanisms to support resource-aware allocation and adaptive behavioral policy adjustment. Experimental evaluation on autonomous tool invention demonstrates that our approach significantly improves both the accuracy of decision confidence estimation and overall task success rate. These results validate the efficacy of metacognitive mechanisms in real-world physical deployment and establish a novel architectural paradigm for designing cognitively capable embodied agents.

📝 Abstract
Robots today often miss a key ingredient of truly intelligent behavior: the ability to reflect on their own cognitive processes and decisions. In humans, this self-monitoring or metacognition is crucial for learning, decision making and problem solving. For instance, they can evaluate how confident they are in performing a task, thus regulating their own behavior and allocating proper resources. Taking inspiration from neuroscience, we propose a robot metacognition architecture centered on confidence (a second-order judgment on decisions) and we demonstrate it on the use case of autonomous tool invention. We propose the use of confidence as a metacognitive measure within the robot decision making scheme. Confidence-informed robots can evaluate the reliability of their decisions, improving their robustness during real-world physical deployment. This form of robotic metacognition emphasizes embodied action monitoring as a means to achieve better informed decisions. We also highlight potential applications and research directions for robot metacognition.
