The authors describe a new design of haptic texture display consisting of fifty vibratory pins that evoke a virtual touch sensation of textured surfaces contacted to the user's fingerpad. A pin drive mechanism was fabricated by adjusting a natural frequency to expand the displacement of a piezoelectric actuator efficiently. An improved control system(More)
In factory automation (FA) industry, it is essential for the working environment using industrial robots to be provided with measures that assure operator's safety and good usability of machines. We have studied the operator's safety and usability of portable robotic operation terminals, and have developed the standardized terminals for one-hand operation(More)
In this paper, we propose the automatic exterior orientation procedure for the Low-cost Unmanned Aerial Vehicle (UAV) photogrammetry. The Low-cost UAV has become useful tool for low altitude photogrammetry from the rapidly increasing of automatic control technique in past several years. However, automatic exterior orientation is still important issue. The(More)
In an effort to optimize our production system, in 2000 we introduced a robot cell production system controlled by low carbon-footprint Senju (thousand-handed) Kannon Model robots on our manufacturing line. Since then, over a period of 11 years, we have successfully produced more than 52 million product units, using this cell production system. During this(More)
Mobile IPv6 is considered to be one of the key technologies for realizing mobile Internet which enables seamless communication between fixed line and wireless access networks. In this paper, we introduce the basic concept of Mobile IPv6 and describe the detail procedure of handoff of mobile terminal. We analyze its effectiveness of Mobile IPv6 handoff by(More)
A novel video system for providing personalized MPEG2 video content to each user is being developed. In this system, video servers multicast multi-angle video streams with meta-data (which describe the contents of the videos). The meta-data are created in relation to a "group of pictures" (GOP), which is capable of decoding itself without other video data.(More)
