Knowledge, understanding, and behavior

What does it mean to know something? What is understanding? How does understanding influence behavior? These are philosophical questions that have occupied the best human minds since time of the ancient Greeks. Only in the last 50 years have scientists been able to address these issues with empirical methods. Only in the last decade has the computational power become widely available to pursue these questions beyond the domain of toy problems. Recent results in the field of autonomous ground vehicles are yielding insights into how to acquire and structure knowledge so as to produce intelligent behavior in the domain of autonomous ground vehicles.
