We developed a reconfigurable brachiating space robot (RBR) based on modularized design, cable reduction, and distributed control able to move over KIBO (Japanese experimental module) of the International Space Station in a brachiating manner and to reconfigure its arms based on task requirements. This paper presents RBR capabilities, focusing on grasping handrails and reconfiguration. We conduct experiments to evaluate RBR brachiation and reconfiguration and present results.
This paper traces research and development in the field of lubrication technology for various mechanical elements. Japan is now in the process of developing the Japanese experimental module (JEM), one component of the US Space Station. This paper therefore emphasizes results relating to mechanical elements that will appear in JEM mechanisms. Methods of lubricating ball-bearings, sliding bearings, ball screws and gears for space use are described and some test results are given.
AbstractWe propose an X-ray all sky monitor for Japanese Experimental Module (JEM) on the space station. Considering practical circumstances, we show as a case study that the all sky monitor with slit hole cameras is most promising for monitoring the short-term and long-term X-ray transients. We call this all sky monitor as MAXI (Monitor of All-sky X-ray Image). Position determination of gamma-ray bursts could be achieved with accuracy less than one degree observing the X-ray component of the burst. Weak X-ray sources such as active galactic nuclei could be also monitored with time resolution less than one day. The X-ray all sky monitor will work to discover X-ray novae and transient phenomena and give us the alarm for further detailed observations. The obtained data will be also used for archival study.
