PHYSICAL TOKEN ENGINE FOR PHYSICAL ARTIFICIAL INTELLIGENCE

A Physical Token Engine receives physical state signals from sensors of a physical artificial intelligence device and generates model consumable physical tokens. The engine may include a physical signal interface, temporal-alignment circuitry, modality-responsive frontends, learned or deterministic token-generation circuitry, body topology encoding, validity processing, scheduling, token caching, and one or more output interfaces. A physical token may identify a modality, body location, kinematic relationship, event, timestamp, priority, validity state, codebook version, and encoded physical payload. The engine may suppress redundant data and provide event-responsive tokens through a prioritized or safety-isolated path. Distributed implementations may tokenize signals locally in hands, feet, limbs, actuators, or sensor modules. The engine may translate robot-native signals into a canonical embodiment space and may configure tokenization according to an intended physical action. Compatible tokens may be generated from real sensors, simulation, digital twins, and recorded traces.
