Sony’s expressive quadruped learns routines, recognizes familiar faces, maps its environment, and develops an individual behavior profile over time.
Best understood as a premium, mobile character rather than a utility robot: unusually expressive and technically sophisticated, but expensive and deeply tied to Sony’s service.
Capability descriptions are based primarily on current manufacturer documentation. They are not independent performance test results.

Companion robots are not substitutes for professional care, clinical judgment, emergency services, or human consent. Safety depends on the exact model, environment, user, and region.
