An automated guided vehicle (AGV) cannot reach its desired position unless its position is detected and its movement is controlled. This study mounts two sound sources on a moving object modeled on the AGV, one on the left side and the other on the right side of the object. The positions of the sound sources are detected as they emit sounds at different frequencies. In addition, the numbers of revolutions of two wheels that are driven independently from the sound sources are controlled to guide the moving object to the desired position. This paper presents a basic test in which the hardware and software parameters of the proposed guidance system are optimized by the parameter design in quality engineering. Model-based testing as it is, it demonstrates that parameter optimization of the guidance system leads to swift and accurate guiding of the moving object to the desired position. This test result confirms the feasibility of the sound guidance system for AGVs.

International tourists in Japan are increasing year by year, and the Japanese government keeps promoting the tourism industry. In order to make Japan more attractive for tourists, the analysis of tourists' impressions is very important. One of the conventional approaches is to provide tourists with a questionnaire about sightseeing spots. However, the questionnaire has a problem, the memory of the interviewees fades and fine information cannot be obtained. In this paper, we describe a novel approach to detect the impression using information from electroencephalogram (EEG). Since the developed system makes use of a portable EEG device, it enables impression detection even if the subject is walking. In order to confirm the validity of the proposed system, we carried out both video-based and real-world experience of the typical sightseeing spots.

モータとボールねじからなる精密位置決め装置に存在する数箇所の熱源(主に,ボールねじ部と軸受部)により,位置決め装置のステージの熱変形ドリフト(熱に起因する位置決め誤差)が生じる.そこで本研究では,精密位置決め装置の軸受ハウジング側面2箇所とステージ上面の計3箇所にペルチェモジュール(以下,ペルチェと呼ぶ)を取り付け,ペルチェにかかる電圧を制御しながら冷却を行い,熱変形ドリフトを低減することを目指した.実験の結果,ハウジング部に対しては温度フィードバッグ制御を,ステージに対しては軸の熱変形量をフィードバッグ制御することにより,速度250mm/s,加速度1Gまでの条件下で,軸の熱変形量を2μm程度まで低減することに成功した.
