Accidents between battery-operated vehicles and pedestrians are expected to increase as electric vehicles (EV) or plug-in hybrid vehicles (PHV) are widely used in near future because of small ambient noise of EV/PHV. To prevent such accidents, a portable alert system for pedestrians to detect approaching vehicle is proposed in this paper. The alert system exploits ultra-wideband impulse radio (UWB-IR)...
Recently, mobile indoor robots have been intensively studied. When such mobile robots are operated, it is necessary to generate their trajectory automatically. In this study, a system which automatically generates the target trajectory avoiding obstacles in the indoor environment by real-time optimization is developed. Conventional artificial potential field method directly generates force which leads...
Japan is a natural disasters prone country. In the Hanshin Awaji great earthquake in 1995, over 6000 people were killed. If appropriate rescue activities had been performed, the probability of survival would have been fairly high. From such experience, various proposal and development of rescue apparatus are being researched now. In our project, we develop small searching machine called UMRS (utility...
