Talking to Godot: dialogue with a mobile robot

Godot is a mobile robot platform that serves as a testbed for the interface between a sophisticated low-level robot navigation and a symbolic high-level spoken dialogue system. The interesting feature of this combined system is that information flows in two directions: (1) the navigation system. supplies landmark; information from the cognitive map used for the interpretation of the user´s utterances in the dialogue system; and (2) the semantic content of utterances analysed by the dialogue system are used to adjust probabilities about the robot´s position in the navigation system.
