  • 23201.美国宇航局格伦研究中心的小型放射性同位素动力系统

    [电气机械和器材制造业,电力、热力、燃气及水生产和供应业] [2013-12-28]

    In April 2009, NASA Glenn Research Center (GRC) formed an integrated product team (IPT) to develop a Small Radioisotope Power System (SRPS) utilizing a single Advanced Stirling Convertor (ASC) with passive balancer for possible use by the International Lunar Network (ILN) program. The ILN program is studying the feasibility of implementing a multiple node seismometer network to investigate the internal lunar structure. A single ASC produces approximately 80 W(sub e) and could potentially supply sufficient power for that application. The IPT consists of Sunpower, Inc., to provide the single ASC with balancer, The Johns Hopkins University Applied Physics Laboratory (JHU/APL) to design an engineering model Single Convertor Controller (SCC) for an ASC with balancer, and NASA GRC to provide technical support to these tasks and to develop a simulated lunar lander test stand. A controller maintains stable operation of an ASC. It regulates the alternating current produced by the linear alternator of the convertor, provides a specified output voltage, and maintains operation at a steady piston amplitude and hot end temperature. JHU/APL also designed an ASC dynamic engine/alternator simulator to aid in the testing and troubleshooting of the SCC. This paper describes the requirements, design, and development of the SCC, including some of the key challenges and the solutions chosen to overcome those issues. In addition, it describes the plans to analyze the effectiveness of a passive balancer to minimize vibration from the ASC, characterize the effect of ASC vibration on a lunar lander, characterize the performance of the SCC, and integrate the single ASC, SCC, and lunar lander test stand to characterize performance of the overall system.

  • 23202.设想:精神循环基础的半活性机器人控制

    [计算机、通信和其他电子设备制造业,电气机械和器材制造业] [2013-12-28]

    This paper describes ongoing research into the role of optic-flow derived spatial representations and their relation to cognitive computational models of mental rotation in primates, with the goal of producing effective and unique autonomous robot navigational capabilities. A theoretical framework is outlined based on a vectorial interlingua spanning perception, cognition and motor control. Progress to date on its implementation within an autonomous robot control architecture is presented.

  • 23203.遗传性分析链传动的机器人手真实的触觉

    [电气机械和器材制造业] [2013-12-28]

    Recently, a real-world haptics which transmits a haptic sensation in real-world has been actively researched. Conventional research of real-world haptics often used low-degree of freedom system. However to transmit human-like haptic information, multi-degrees of freedom robot should be used. On the other hand, general hand robot as multi-degrees of freedom robot often used force sensor. The force sensor can not get the force information which is applied from other points. Therefore, in this research, bilateral control is applied to chain-driven hand robot. Bilateral control based on disturbance observer and reaction force observer can obtain all force information which is applied to robot. The chain-driven robot has some friction and backlash because of chain and gear. These causes of degradation haptic transmission. Thus, in this research, haptic sensation is transmitted by chained driven hand robot. Then, it is analyzed how haptic information the chain-driven robot transits by using transmissibility. Transmissibility is calculated by experiment.
