What is it about?

Human activities are frequently related to navigational tasks and human tend to use descriptions which include natural language phrases and uncertain terms such as “near”, “little”, “far”, “small”, “large”, “close” to describe about spatial information. Therefore assistive robots should be capable of analyzing and understanding descriptions which contain natural language phrases with uncertain terms and creating a conceptual map for effective navigation

Why is it important?

This paper proposes a method to understand spatial information in a description with uncertain terms and creates a conceptual map in a robot memory which can be linked with a spatial map for purposeful, effective and human-friendly navigation task


The proposed system is capable of creating a virtual map or imagine a representative map of an unknown environment before the robot actually perceives visual sensory information from the environment.
