Abstract: In this paper the development of a new architecture for the control of
autonomous mobile robots is shown. To build the architecture we have had in mind
how the mental human processes are. The developed architecture has two levels: a
deliberative one and an automatic one. For this reason. this architecture has been
named AD (Automatic-Deliberative Architecture).In the deliberative level we find
those skills that require high computational time as a consequence of high level
reasonings. In the automatic level we find the skills that interact with robot sensors
and actuators. Copyright © 200] ]FAC

1. IKTRODUCTION
V/hen considering a new control architecture in
the robotic world. the first question is how the
reasoning capacity and the actuation are
distributed. The new architecture. considered as a
hybrid one. pretends to combine planification and
reactiw actions.
To build the new control architecture we are go-
ing to consider the human beings organise
their mental processes. Once more. nature is going
to proportionate the models to imitate. There-
fore. the motivation of the AD architecture is the
human being reasoning capacity and the actua-
tion capacity. In this paper we reflexionate about
the in which humans organise their mental
processes. As a consequence of those reasonings.
we present the new AD architecture (Automatir-
Deliberatiw Architecture) .

2. PRECEDINGS
The actual trend is to incorporate deliberation
and reactivity in the same architect.ure. Consid-
ering this. we are going to emphasize on the three
layer architectures developed Firby. Gat and
Bonasso. They mark the present tendency and
these architectures can be considered as preced-
ings of the AD architecture proposed in this pa-
per.
2.1 Animate Agent Architecture
James Firby (Firby 1992) (Firby 1994) developed
an execution of plans named RAP which
is based on a "reactiw packages program".
The complete architecture is shown on figure 1.
On it. we can obserw three layers: a planification
layer that produces plans depending on the goal.
the RAP executor which deepens in the details
of the preyious plan in execution time. and a
control system which performs actions on the
enyironment.
