Laser based environment recognition technologies have been developed recently. Especially moving objects detection and classification by laser scanners mounted on a mobility is required for mobile robots and autonomous cars. In this paper, we propose a moving objects detection and classification method based on grid trajectories acquired from sequential laser scan data. Grid trajectories are obtained...
Human interaction based on conversation and gestures is very important to realize the natural communication. This paper proposes a conversation system composed of topic selection module, conversation control module and utterance selection module. First, we apply a Bayesian network for the topic selection, and Boltzmann selection for the control of conversation. We apply term frequency inverse document...
This paper describes development of ldquoiDockrdquo, which is used for a container temporal stacker. iDock serves as if it is a mail-box in the post-service or a service station of the door-to-door delivery system to improve efficiency of domestic delivery and storage robot system. The instrument realizes stack of containers, recognition of contents in containers, and navigation of robots. To acquire...
This paper describes development of home-use automated container storage/retrieval system, a sub-system of a logistical support robot system in living space. The s/r system has 3 features. (1) Elevator type structure enables not only auto stocking motion, but also human access to containers as if the auto rack is a general shelf. (2) A separated motion layout enables us to utilize upper ceiling space...
