Many indoor navigation robots use structured light vision measurement systems (SLVMS) for mapping, localization, and obstacle avoidances. In these systems, the extraction of light stripe skeleton directly affects the accuracy of the final measurements. One of the problems in SLVMS is that when the light is projected to some rough surface it will cause strong diffuse reflection. Thus the light stripe...
The technique of tuning a cavity filter is purely a rule of thumb: only experienced tuning engineer is competent to the task. However, with the great development of the communication industry and the rapid increasing of production capacity, the need for tuning technicians becomes urgent. It is meaningful to replace this traditional manual tuning task with some more advanced and automatic methods....
Clothbot is a new kind of climbing robot with novel structure that enables it to move on human cloth. Earlier version of Clothbot can only climb on cloth with manual control because there is complex deformation on human cloth and thus Clothbot can't keep itself stable. In this paper, we propose some new hardware improvements to enhance the stability of Clothbot on human cloth, then adopt a remote...
The operational difficulty of Transcranial Doppler (TCD) limits its use in normal clinical settings. We therefore present a robotic arm consists of five degrees of freedom which are achieved by four motors and one extra flexible spring, to assure appropriate pressure on temporal window. With proper control strategies, the robotic arm can move the TCD probe to automatically search temporal window positions...
The paper proposes a dancing robot based on the beat tracking method. The robot can carry out different actions when receiving different musical signal input. The dancing poses are vivid and lifesome, and development of the robot is helpful to enhance intelligence of the traditional creational robot, which exerts a striking influences on the conventional toy market. In the paper, the design of the...
The aging of population has become a social problem and fall is a major health risk in the elderly. To this end, this paper presents a novel approach for fall detection applied to an intelligent household surveillance robot. Silhouette based features are extracted, including aspect ratio of minimal bounding box of the human silhouette, approximated elliptical eccentricity, normalized central moments...
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...
Language plays an important role in human and household service robot communication, and speech not only contains semantic information, but also involves the tone and emotion information of speakers. We have developed a chatting robot prototype which can use speech to communicate with users. The semantic information are used to produce response by this robot. However the emotion information is also...
