    This paper presents a hierarchical control system which enables the collision free operation of a multiple robot workcell. The method assumes that the motions to be performed are known beforehand, and initial collision free paths are planned offline. A monitor then tracks the actual robot motions. Any deviation from the preplanned path may result in a collision situation thus a collision detection... View full abstract»

    All approaches to rule-based control have relied upon a pre-classification of the state-space for their success. Given a classification of the state-space, either an individual control action or a whole set of control actions can be learnt. But quality of control is limited by the quality of the state-space classification. When no classification is specified, a more challenging problem is how to a... View full abstract»
