How can we build robots that engage in fluid spoken conversations with people, moving beyond canned responses to words and towards actually understanding? As a step towards addressing this question, we introduce a robotic architecture that provides a basis for grounding word meanings. The architecture provides perceptual, procedural, and affordance representations for grounding words. A percept...

This paper examines a few methods used in grounding analysis and illustrates the advantages, limitations, and the applicability of these methods. Computation results using these methods are presented and compared. The various cases modeled in this paper include grounding networks of different sizes, grounding networks with buried metallic structures such as steel pipes, and high frequency cases...

Analysis of the Symbol Grounding Problem has typically focused on the nature of symbols and how they tie to perception without focusing on the actual qualities of what the symbols are to be grounded in. We formalize the requirements of the ground and propose a basic model of grounding perceptual primitives to regions in perceptual space that demonstrates the significance of continuous mapping a...
