. Avant-de, execution enparalì ele des deux stratégies de navigation, il restè a résoudre la question de la resynchronisation des dynamiques temporelles Je propose dans la section suivante un mécanisme de " chunking " qui permet au robot de resynchroniser la séquence de ses déplacements par rapportàrapportà la détection d'´ evénement complexe

. En-psychologie,-le-processus-de, une séquence présente dans une mémoirè a court terme en une seule unité Ici un chunk représente une sous séquence. Par exemple, considérons une série de chiffre On a ici une séquence de chiffre qui n'est pas forcément simple de mémoriser. Maintenant, représentons cette série d'unemanì ere différente : " 07 45 26 19 98 " . En regroupant deuxàdeuxà deux les chiffres, on obtient alors des nombres un peu plus simplè a retenir. Ceci est surtout dû au fait que la séquence n'est plus une série de dix chiffres mais de cinq nombres. Ce regroupement de deux chiffres en un seul nombre correspond au processus de " chunking " et chaque nombre est alors un chunk. Dans [Grossberg, 1999], l'auteur utilise ce mécanisme pour encoder une sous-séquence d'entrées auditives présente en mémoirè a court terme, 1974.

. Dans-les-deux-exemples-cités-ici, un chunk code soit un sous ensemble d'´ etats d'une séquence, soit un sous ensemble de points d'intérêt. On peut alors définir un chunk comme une unité codant une situationparticulì ere dans un comportement global

. Dans-mes-travaux, En utilisant la stratégie d'associations lieux-mouvements, le robot navigue de lieux en lieux en appliquant les commandes motrices qui y sont associées. Ces informations sont alors toutàtoutà fait pertinentes pour Références [Albus, 1975] Albus A new approach to manipulator control : the cerebellar model articulation controller (cmac, J. S.
