Abstract

This paper discusses the emergence of sensorimotor coordination forESCHeR, a 4DOF redundant foveated robot-head, by interaction with itsenvironment. A feedback-error-learning (FEL)-based distributed controlprovides the system with explorative abilities with reflexes constrainingthe learning space. A Kohonen network, trained at run-time, categorizes thesensorimotor patterns obtained over ESCHeR‘s interaction with itsenvironment, enables the reinforcement of frequently executed actions, thusstabilizing the learning activity over time. We explain how the developmentof ESCHeR‘s visual abilities (e.g., gaze fixation and saccadic motion), froma context-free reflex-based control process to a context-dependent,pattern-based sensorimotor coordination can be related to the Piagetian‘stage theory’.
