Abstract
Looking at the history of Artificial Intelligence, often theoretical rigor
seems inversely proportional to practical applicability. Particularly, in
the field of robotics, there is a gap between the research on knowledge
representation and practical robotics. In the present paper, a solution for
bridging this gap is described and discussed: Shanahan's logical account for
a mobile robot. Called ``A Logical Account for the Common Sense Informatic
Situation for a Mobile Robot'', this framework involves the assimilation of
sensor data, and action planning, through an abduction process on theories
about actions and change, and space and shape. An extension of the Event
Calculus is taken as the underlying logical system. Actually, these theories
are fragments of second-order logic since Circumscription (which is expressed
in second-order logic) is used to overcome the frame problem.
However, the solution presented to the frame problem does not cope with all
of the issues concerned with this problem (since the solution deals only
with the persistence problem); moreover, due to the lack of an algorithm
capable of automatically constructing theories about the background knowledge,
it is impossible to affirm whether the solution presented solves, in a general
way, the problem for which it is proposed.
Finally, the analysis of the computational complexity of the framework in
question made us conclude that, in the general case, its complexity is at
least complete for the second level of the polynomial hierarchy.
