- 요약As robots become integrated into modern society and play key roles in industries like transportation, healthcare, and manufacturing, these systems must interact closely with humans and make real-time decisions that prioritize safety. This growing reliance highlights the need for responsible robotics-systems that not only perform tasks efficiently but also make reliable, safe, and ethically sound decisions in complex environments. The most critical aspect of responsible robotics is ensuring physical safety, preventing harm during operation. However, achieving this is not as simple as telling robots to "avoid collisions", as robots may face sensing failures, environmental disturbances, and unpredictable behaviors from others. Drawing inspiration from control theory, machine learning, and social science, this thesis aims to develop theories and algorithms that enable robots to proactively identify potential risks, mitigate them effectively, and verify their decisions in real time to ensure safe operation throughout the execution of their tasks in complex environments while balancing safety and efficiency.This thesis focuses on developing robot decision-making methodologies with formal physical safety guarantees. My first line of work addresses the functional safety of individual robots' actions, ensuring they can operate robustly against motion uncertainties. A probabilistic adaptive safety verification filter ensures immediate safety and a risk evaluation framework biases robot decisions to account for long-term safety. This allows robots to adapt to varying levels of uncertainty, displaying a range of safety-critical behaviors from conservative to efficient. The concept of functional safety is then extended to address collaborative safety in multi-robot systems, where teams of robots must interact safely and efficiently. The thesis formalizes the first responsibility-reasoning framework, allowing individual robots to contribute to a collective goal by reasoning over their roles in a decentralized manner. This framework demonstrates group intelligence, allowing robots with diverse capabilities and intentions to collaborate effectively with aligned heterogeneity while maintaining both safety and efficiency. Lastly, we address the challenge of representational safety, which emerges when safety specifications either fail to align with social expectations or are not explicitly defined in advance. A risk-informed specification formalization contextualizes high-level moral principles, such as those inspired by Asimov's Laws, into physically meaningful motion constraints, enabling robots to exhibit socially compliant behavior. For under-defined safety specifications, a causality-embedded, model-based learning approach infers the unknown parameters of implicit safety notions from interaction data and behavioral observations. Together, these methods enable robots to uphold safety concepts grounded in human values, while learning ambiguous or evolving safety specifications without requiring explicit labels.Collectively, these efforts support the broader goal of responsible robotics by enabling robots to reason about and respond to external environments at multiple levels, from individual decision-making to team coordination and specification learning. By advancing safety in function, collaboration, and representation, this thesis lays the groundwork for autonomous systems that are not only physically safe, but also capable of behaving responsibly in uncertain and dynamic environments.
