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 lowlevel 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. (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.
