This book covers allaspects of robot intelligence from perception at sensor level and reasoning atcognitive level to behavior planning at execution level for each low levelsegment of the machine. It also presents the technologies for cognitivereasoning, social interaction with humans, behavior generation, ability tocooperate with other robots, ambience awareness, and an artificial genome thatcan be passed on to other robots. These technologies are to materializecognitive intelligence, social intelligence, behavioral intelligence,collective intelligence, ambient intelligence and genetic intelligence. Thebook aims at serving researchers and practitioners with a timely disseminationof the recent progress on robot intelligence technology and its applications,based on a collection of papers presented at the 4th International Conferenceon Robot Intelligence Technology and Applications (RiTA), held in Bucheon, Korea, December 14 - 16, 2015. For better readability, this editionhas the totalof 49 articles grouped into 3 chapters: ChapterI: Ambient, Behavioral, Cognitive, Collective, and Social Robot Intelligence,Chapter II: Computational Intelligence and Intelligent Design for AdvancedRobotics, Chapter III: Applications of Robot Intelligence Technology .
