Abstract The Humanoid Operating System (HOS) defines a standardized software architecture for governing humanoid robots through constitutional execution, whole-body resource management, capability-based execution authority, and deterministic physical control. Unlike conventional operating systems that manage computational resources such as processors and memory, HOS introduces native operating-system abstractions for humanoid embodiment, including body resources, physical cap

This document represents our initial architectural proposal for what we believe will become a new class of operating system designed specifically for humanoid robots and other embodied Physical AI systems.

Abstract This document defines the Humanoid Constitution, a machine-enforceable governance architecture that regulates physical authority within humanoid robots. The Constitution establishes rules governing physical execution, mission authority, ownership, custody, trust, human interaction, validator selection, and release authorization. Unlike conventional safety systems, the Constitution represents a first-class operating-system abstraction that determines whether a propose

Humanoid robots are transitioning from research platforms into general-purpose physical computing systems capable of operating in homes, hospitals, warehouses, offices, factories, retail environments, and public spaces.
