....agents can employ attentional resources. A multi resolutional society of interacting mental models organized into a three level hierarchical structure (see Figures 2 and 4) can be constructed corresponding to Rasmussen s knowledge based (KB) rule based (RB) and skill based (SB) behaviors 2 [8, 38, 40, 41, 46]. At the KB level of this hierarchy, the agent role is supervisory; at the RB level, the agent role is task management; and at the SB level, the agent role is task execution. Intuitively, the KB, RB, and SB agents think, monitor, and control, respectively 3 . 1 A decision u is often treated as ....
....treatment of satisficing [29] which has not been generalized in SDT. It appears that an axiomatic treatment for SDT can be obtained by modifying the axioms in [29] using concepts from multi attribute utility theory. In addition to the abstraction hierarchy of human behavior developed by Rasmussen [8, 38, 40, 41, 46], the field of intelligent control relies on multi resolutional behavior generation [1, 2, 23, 34, 44] The foundational idea behind these developments is that a hierarchy of multi resolutional modules is an efficient way to encode knowledge, to interpret sensory information, and to generate ....

....specific interaction features such as intrinsic object properties, information on how to interact with it, objects functionality, and as well as expected agent behaviours. Rule based behavioural systems are well known and often exploited to simulate behaviours (Reynolds, 1999 ,Chaib draa, 1997, Neves and Oliveira, 1997, Zeltzer, 1997) Several authors have used it in order to describe human and animal behaviours. We present an RBBS (Rule Based Behaviour System) which describes a syntactic analyser of natural language in order to specify behavioural rules to guide crowds. We base our rule based behavioural ....

There are also a number of hybrid architectures rising from the explicit need of particular applications, to which both former approaches are not adequate, as it is the case with more elaborate robotic tasks. Fir 92] Oli 97] Nev, Oli 97] An important open issue in hybrid multi agent systems (as well as for the agent itself) is what we can call the problem related with the schizoid syndrome [Oli 97] The source of this syndrome is the fact that several different agents with different capabilities, architectures and response ....

....of the last sections of this paper, as an agent that can interact with the world, possibly including also other robots. Now it is time to precise how to control one robot s action by means of these two main capabilities, we know are present at the robot control level: Deliberation and Reactivity [6]. Being strongly against giving control of the robot s activity either to a planning module or to a reactive mechanism, gives us the responsibility to find out some other way of defining what happens mediating sensing and action. And the answer seems to be that robots actions should be the result ....
....agents. Moreover, through the informing planner channel, they can convey information to the cognitive agent, working at the symbolic level. It is also true that the latter is able to send some some useful advices to the lower level, in order to influence the way behaviors may be combined (see [6] for details) In conclusion we may say that, emerging from the agents interaction we can recognize an a apropriate, flexible and evolutive global robot behavior.
