Service robots deployed in domestic environments generally need the capability to deal with articulated objects such as doors and drawers in order to fulfill certain mobile manipulation tasks. This however, requires, that the robots are able to perceive the articulation models of such objects. In this paper, we present an approach for detecting, tracking, and learning articulation models for cabinet...
In many societies, the aged people are often living alone. For the aging population, surveillance in household environments has become more and more important. In this paper, we present a household surveillance robot that can detect abnormal events by utilizing video and audio information. In our approach, moving targets can be detected by the robot with a passive acoustic location device. Then the...
Dual floor image tracking (DFIT) is a dead reckoning component, which acquires optical flows of ground images from two cameras. The robot that is equipped with the DFIT can measure its position and rotation without being affected by slip or drift. Noncontact feature of the DFIT enables to add-on robots with an arbitrary driving mechanism. This paper presents the design principle of the DFIT and the...
In this paper, we propose an approach to the book recognition system where the books on bookshelves are detected and recognized by line segment, MSAC based dominant vanishing point detection, singular value decomposition (SVD) based text recognition and semantic network. Our system can be equipped to robot intelligence to handle some works such as arranging, searching books which had formerly done...
The main task of rescue robots is to locate victims after a disaster such as an earthquake. For this task sensor data is used to localize the robots in their environment, build maps, and mark the victims in the maps. Usually, thermal and color cameras, monitored by a human operator, are used for the detection. Hyperspectral imaging techniques are today used for industrial tasks such as quality control,...
The tasks of autonomous rescue robots operating in unknown environments are manifold. Self localization, map generation and the detection of possible victims are indespensable. Apart from these, other factors can become crucial for the survival of the involved persons and for the safe operation of the robot itself. A first step in autonomously detecting such dangers is the real-time recognition of...
