Abstract:This talk presents our recent projects on autonomous mobilerobots. The projects aim at developing personal service robots thatcan assist people in their daily life. The ability of movingautonomously in various environments, both indoor and outdoor, is oneof the fundamental functions for such robots, and is realized bycombining several technologies such as localization and mapping,motion planning, and human detection and tracking. The talk will coverthe following topics: development of person following robots, a newviewpoint planning strategy for an attendant robot (or guard robot),and multisensory fusion for reliable road detection.
