Organizational Trajectories in Adaptive Robotic Systems: A Psychorobotic Framework for Four Depths of Change

Embodied adaptive robotic systems can change in fundamentally different ways: they may undergo transient state variations, update parameters and models, move between operational regimes, or alter their functional organization. This article extends the descriptive-functional level introduced by psychorobotics into the temporal domain by distinguishing four depths of change: Level 0, transient state variation; Level 1, parametric adaptation; Level 2, regime reconfiguration; and Level 3, organizational transformation. The framework distinguishes instantaneous configuration, realized organizational profile, and the organizational grammar that makes profile classes and transitions available; it also separates depth from generative mechanism and evidential strength. Organizational equivalence is assessed under a declared analytical protocol that specifies the carrier, scale, windows, contexts, invariants, tolerances, and planned interventions; prospective declaration is required for the robustly documented standard. Applied to a targeted comparative corpus of fourteen studies of robotic systems, the framework identifies two supported Level 3 cases at collective and modular-system scales, although neither meets the full standard of longitudinal observation, matched intervention, prediction, and independent validation. The study by Ruppert and Badri-Spröwitz is classified as Level 1 supported, with Level 2 retained as a candidate because the available evidence does not discriminate a distinct regime under the present criteria; the study by Kawaharazuka et al. is classified as Level 1 supported, with manifest structural change but Levels 2 and 3 not demonstrated. The analysis further shows that learning, performance recovery, increased complexity, self-organization, and structural reconfiguration do not in themselves demonstrate organizational transformation. A target-specific intervention protocol is proposed to test persistent changes in roles, dependencies, authority, and system partition while keeping implementation change analytically separate from functional depth.
