Intention reconsideration in theory and practice

Autonomous agents operating in complex dynamic environments need the ability to integrate robust plan execution with higher level reasoning. This paper describes work to combine low level navigation techniques drawn from mobile robotics with deliberation techniques drawn from intelligent agents. In particular, we discuss the combination of a navigation system based on fuzzy logic with a deliberator based on the belief/desire/intention (BDI) model. We discuss some of the subtleties involved in this integration, and illustrate it with an example.
