Autonomous Wheelchair Rolland: Verbal Route Descriptions

This video demonstrates the use of natural language route descriptions in the mobile robot navigation domain. Guided by corpus analysis and earlier work on coarse qualitative route
descriptions, we decompose instructions given by humans into sequences of imprecise route segment descriptions. By applying fuzzy rules for the involved spatial relations and actions, we construct a search tree that can be searched in a depth-first branch and-
bound manner for the most probable goal configuration w.r.t. the global workspace knowledge of the robot. The applicability of our approach is shown by a real-world experiment where
Rob instructs his automated wheelchair to navigate in an office-like environment.
