The architecture constructed with two types of processing, logical sym
bol processing and stimulus-reaction type parallel processing, seems p
romising for intelligent systems. Since symbol processing is construct
ed by a top-down approach and stimulus-reaction type processing is bui
lt up by a bottom-up approach, a discrepancy, which is called the 'sym
bol grounding problem', takes place. This paper presents a framework f
or integration of symbol processing and stimulus-reaction type process
ing from the viewpoint of solving the symbol grounding problem. In thi
s framework designers or users use the conventional heuristic symbols
and the systems use the self-organized symbols based on the characteri
stics/environment of the systems themselves. Translation from one to a
nother produces the fusion of those two symbols. The self-organized sy
mbols are grounded and manipulative. Navigation of an autonomous robot
is simulated. Acquisition of manipulative,grounded symbols with the p
roposed framework is demonstrated. Since the constructed robot is equi
pped only with a stimulus-reaction type controller, it has a robustnes
s against noise and temporary geometrical changes.
