This paper is primarily concerned with answering two questions: What a
re necessary elements of embodied architectures? How are we to proceed
in a science of embodied systems? Autonomous agents, more specificall
y cognitive agents, are offered as the appropriate objects of study fo
r embodied AI. The necessary elements of the architectures of these ag
ents are then those of embodied Al as well. A concrete proposal is pre
sented as to how to proceed with such a study. This proposal includes
a synergistic parallel employment of an engineering approach and a sci
entific approach. It also supports the exploration of design space and
of niche space. A general architecture for a cognitive agent is outli
ned and discussed.
