In this paper we propose a 1DOF master-slave system called HandShake Device (HSD). HSD is composed of 2 systems: one is a master system, which is grasped by an operator, the other is a slave system, which grasps the operator's palm. Two HSDs are respectively placed at a local site and a remote site so that people can physically communicate (by shaking hands) each other through HSDs. HSD applies the virtual model method as an algorithm of tele-operation (tele-handshake). HSD was exhibited in SIGGRAPH'95 with Network Neuro Baby (NNB) which is an Artificial Life acting as a network agent in the computer network. HSD is an interface device which an operator can communicate with NNB physically.

The purpose of this study was to investigate the effects of postexercise carbonated high-carbohydrate beverage (Carbonated Trial: CT) compared with non-carbonated high-carbohydrate beverage (Non-Carbonated Trial: NCT) on gastrointestinal (GI) problems and physiological indexes during 4 hours of recovery period in athletes. Eight Japanese collegiate athletes (age : 21±1yr ; height : 170.8±6.0cm ; body weight(BW) : 68.70±8.29kg ; percent body fat : 11.7±2.7%) participated in the cross-over designed study. Immediately after the exhaustive exercise, subjects consumed 3.5ml/kg BW of 1) water, 2) high-carbohydrate beverage : NCT (1.8gCHO/kg BW/h), and 3) carbonated high-carbohydrate beverage : CT (1.8gCHO/kg BW/h) every 30 min during 4 hours of recovery period. No difference was observed in blood concentration of glucose, insulin, free fatty acid, and subjective GI problems between CT and NCT. However the rate of vomiting was significantly higher in the NCT compared with CT (p < 0.05). These results suggest that ingesting carbonated beverage during recovery period may help digestion and absorption in the stomach of athletes.

In the environment that human and robots coexist, mobile robots have to approach human as much as possible in order to provide human with physical services. For friendly interaction with human, the robots should be able to afford human-affinitive movement. In this paper, human following, as one of human-affinitive movements, of robot is achieved. The human following robot requires several techniques; the recognition of the target human, the recognition of the environment around the robot, and the control strategy for stable human following. In this research, Intelligent Space, where many sensors and intelligent devices are distributed, is used for the recognition of the target human and the environment around the robot. The control law based on the virtual spring model is proposed to mitigate the difference of movement between the human and the mobile robot. The proposed control law is applied to Intelligent Space and its performance is verified by computer simulation and experiment.

本研究の最終目的は高精度・広範囲遠隔微細操作を実現することである。複数台のナノマニピュレータを用いたナノロボティックアセンブリシステムを構築し、ナノメカニカルシステム(NEMS)カセンサのアセンブリを実現した。平成19年度にはナノアセンブリシステムによる3次元ナノベルトカセンサの試作に成功した。具体的にはナノインクを用いたロボティックソーダリング、電気抵抗溶接、外部力アシストアセンブリ技術を提案しデバイスアセンブリに有用であることを電子顕微鏡の下で検証した。これらの新たな加工技術は既存のマイクロメカニカルシステム(MEMS)加工技術では不可能である極微細でありながら超柔軟3次元ヘリカールナノベルト(HNB)のようなナノスケール構造物を用いたデバイスアセンブリに非常に有用な技術であると判断される。本課題で提案されるこれらの要素技術により開発されたピエゾ抵抗3次元ナノベルトカセンサは広範囲(数pN〜数百nN)かつ高精度(pN〜nN)を実現した。現在取り組んでいるセンサの大量生産プロセスにより幅広い応用分野で微細マニピュレーションシステムに適用されることが可能になり、単分子バイオ操作やナノ構造物の特性分析のための高精度、広範囲マニピュレーションが期待できる。本課題の最終年度であり、これらの研究成果を世界で情報発信するため、本分野で権威の高い論文誌(6件)、国際会議(8件)、多数の国内会議などに論文を投稿するなど、実りある成果を得ることができた。また、これらの準備過程でより深く同分野の研究者らと議論することができ、今後の新たなブレークスルーとなると考えている。

This paper proposes an electrocardiogram (ECG) measuring system which simultaneously enables the reduction of input impedance and low-frequency cutoff through virtual amplification of the coupling capacitance formed by body capacitance and ECG electrode. This virtual amplification of the coupling capacitance is realized by the additional circuit which controls the inflow of external current to create the situation as if the time constant of the capacitance has increased. Moreover, not only this additional function but the amplification circuits commonly used in ECG measuring system has also been perfectly tuned-up. Here, instead of using the MOS-FET which shows bad noise characteristics, the combinations of J-FET differential amplifier and current feedback circuit have been used for stable amplification. In addition, coupling capacitors of the system are removed due to the DC-Coupling enabled by using single operational amplifiers instead of instrumentation operational amplifiers.

Recently, wireless charging via magnetic resonance coupling has gained attention because it has the potential of efficient midrange wireless charging. Here, functions such as sensing at the transmitter and wireless communication from the target are the essential elements to realize a standard wireless charging system. Currently, the sensing and communication protocol of the hardware (i.e., the high-frequency power source and antenna configuration) compatible with wireless charging is gaining attention in terms of its cost and space reduction due to the use of common components for multiple functions. However, this protocol has the problem of narrow effective areas due to the fact that the sensing range depends on the fixed Q factor of the antenna. To overcome this problem, the concept of wide-area sensing based on a Q controllable antenna is proposed, and the effectiveness is verified through a theoretical analysis and an experiment. As a result, it is clarified that the effective area can be expanded up to a ratio of the distance g between the transmitting and receiving antennas to the inner diameter d of the antenna g/d =5.0.

Immersive virtual reality system has a problem that the operability deteriorates if the shape of the virtual body is parted from the real body. The authors are assuming that this is caused by misfit of the body scheme, an internal model in the brain used to recall the body position, because it is initially tuned up to the real body instead of virtual body. Thus, the authors have proposed a method using VR technology called“ Body Scheme Calibration ”to change the body scheme adapting to the real body so as to fit the virtual body. However, in the previous approach, presented VR information was limited to visual information, and haptic information normally occurring from interaction with surrounding object was neglected. Therefore, this paper investigated the effect of haptic information on Body Scheme Calibration. As an experimental result, it was verified that the effect of additional haptic information is trivial, and the complex haptic interface for this calibration might be omissible.
