This paper investigates a collision-free navigation algorithm for a mobile robot to work in daily environment which includes multiple walking people. The proposed algorithm consists of two main parts: recognizing walking people and collision-free path planning. For the recognition of randomly changing human walking motion, a people tracking method using(More)
—This paper describes a method for recognizing partially occluded objects for bin-picking tasks using eigenspace analysis, referred to as the " eigen window " method, that stores multiple partial appearances of an object in an eigenspace. Such partial appearances require a large amount of memory space. Three measurements, detectability, uniqueness, and(More)
In this paper, we employ Web services, programmable application logic accessible using standard Internet protocol, to enable a robot to access the distributed application logic based on the recent network technologies like XML, SOAP, WSDL, UDDI. Applications can communicate with each other in a platform and programming language independent manner. We first(More)
We propose a collaborative knowledge network that we call omniscient spaces in the attempt to generate sophisticated robotic behavior with minimal programming effort. New products are manufactured and brought into our daily life everyday. Robots should need a way to easily integrate new products into their existing recognizable environments. Radio frequency(More)
This paper describes a method for recognizing partially occluded objects under different levels of illumination brightness by using the eigenspace analysis. In our previous work, we developed the “eigenwindow” method to recognize the partially occluded objects in an assembly task, and demonstrated with sufficient high performance for the industrial use that(More)
In this paper, a novel approach of knowledge management for the space/location perceiving capacity of robots is proposed. First, the ubiquitous function services composed of smart object, smart logic, and smart discovery service are proposed in order to distribute knowledge flexibly and reliably to changing environment and also for a robot to invoke and(More)
