....stick with the plan. Every hybrid robot control architecture must cope with that. Our view of building hybrid robot controllers involving a behavior based robot control system (BBS) Mat99] as reactive component is shaped by our work in progress on the DD P robot control architecture [HJZM98,HS01,SCHC01] The demo example we will present is formulated in a concrete BBS framework, namely, Dual Dynamics (DD, JC97] and we will illustrate how to blend it with classical propositional action planners. The rest of this paper is organized as follows. In Sec. 2, we present our approach of formulating ....

....true) or else while stuck at t i is caught up by another matching front at t i , or else an activation gestalt over an interval ending at t i 1 is no longer valid in the current qualitative activation history. The complexity of this process is O(jBehaviorsj jChroniclesj maxjAGsInChroniclej) see [SCHC01] for details. Practically, the necessary computation may be focused by specifying for each defining chronicle a trigger condition, i.e. one of the qualitative activations in the definition that is used to start a monitoring process of the validity of all activation gestalts. For example, in the ....

While this is crucial information, more can be done.

Certain patterns in these time series are matched against given chronicle definitions in the spirit of [9] a summary will be given ....

....particular way of aggregating sensor values, namely, as is necessary for permanently calculating the degree of activity for each and every behavior on the reactive layer. For fact derivation, they are available for free in the sense that they have to be calculated anyway in the robot control. In [15] chronicles are hand crafted, based on the domain modeler s understanding of how different robot behaviors interact with each other and with the physical environment. In this paper, we attempt to arrive at the same type of hypothesis about symbolic facts true in the recent situation, based on the ....
