This paper presents the space test of the ARH (Advanced Robotic Hand System), which is the world's first precise extravehicular robot aboard the satellite“Hikoboshi”. The telerobotic system has features of dexterity, autonomy and flexible operability, using a three-finger multisensory hand at a work site in space and a computer-graphics-based desktop interface at an operation site on the ground. The concept of sensor-fused telerobotics utilizing multisensory information is introduced, and the system is implemented to perform high precision tasks under the barrier of inter-satellite space communication. The robot system was launched into low earth orbit, and the capability of sensor-fused telerobotics was successfully demonstrated in precise in-orbit servicing.

With the increase in recording density and higher rotation speeds, the aerodynamic aspect of HDD (Hard Disk Drives) is now quite significant. We studied the internal air flow of a HDD by using a direct neumerical simulation. We simulated two cases. The first case has the arm with no weight saving hole (no-hole case). The second case has the arm with weight saving hole (hole case). We observed periodic vortices (Karman's vortex) of which frequency is about 6kHz in the downstream of the arm in both cases. The scale of vortex in hole case is lager than that in no-hole case.
