4. The Autonomous City Explorer

This video was recorded at AAAI 2009: AI Video Competition. This video presents the Autonomous City Explorer (ACE) project. Its goal was to create a robot capable of navigating in an unknown urban environments without the use of prior map knowledge or GPS data. The robot had to find its way solely by interacting with pedestrians and building a topological representation of its surroundings. This video outlines the necessary ingredients for successful low-level navigation on sidewalks, vision processing in cluttered outdoor environments, and information retrieval from pedestrians.
