This chapter provides a review of the development of the field of type-2 fuzzy logic. We explore some underpinning philosophical arguments that support the notion of type-2 fuzzy logic. We give the fundamental definitions of type-2 fuzzy sets and basic logical operations. The key stages in development of the field are reviewed and placed in a historical context. In addition, we report an example application of type-2 fuzzy logic to mobile robot navigation, demonstrating the potential of type-2 fuzzy systems to outperform type-1 fuzzy systems.
