Safety-Bounded Autonomy (Module: A Systems Architecture for Safe Distributed Robotic Systems)

This paper introduces the safety enforcement layer within a broader governance architecture for autonomous robotic systems. It ensures that all system behavior remains within predefined safety boundaries, even under adaptive and learning conditions.

As these systems scale in autonomy and interconnection, ensuring reliable safety guarantees becomes a fundamental engineering challenge. This whitepaper introduces the concept of Safety-Bounded Autonomy, an architectural framework designed to enforce safety constraints directly at the system architecture level. Instead of relying solely on decision-policy correctness or runtime behavioral checks, the proposed approach embeds safety constraints within the structural layers of distributed robotic systems. The framework introduces capability-gated autonomy, where autonomous decision policies generate candidate actions that must pass through architectural validation layers before reaching the control system. These capability gates enforce safety contracts that restrict system actions to a bounded set of safe operational states. The proposed architecture is particularly relevant for distributed multi-agent robotic systems where locally safe decisions may interact to produce globally unsafe outcomes. By embedding safety constraints directly within system architecture, Safety-Bounded Autonomy enables scalable autonomous systems that remain within verifiable safety envelopes. This whitepaper provides a conceptual systems architecture for safe distributed robotics and complements the related research papers on architecture-level safety enforcement and capability-gated autonomy. This work is part of a broader research program on governance and execution control in autonomous robotic systems, including capability governance, safety-bounded autonomy, and non-bypassable execution control architectures.
