Modularity and integration in the design of a socially interactive robot

Designing robots that are capable of interacting with humans in real life settings is a challenging task. One key issue is the integration of multiple modalities (e.g., mobility, physical structure, navigation, vision, audition, dialogue, reasoning) into a coherent framework. Taking the AAAI mobile robot challenge (making a robot attend the national conference on artificial intelligence) as the experimental context, we are currently addressing hardware, software and computation integration issues involved in designing a robot capable of sophisticated interaction with humans. This paper reports on our design solutions and the current status of the work, along with the potential impacts this design on human-robot interaction research.
