A flexible noiseless and high-efficient propulsor plays a prominent role in the performance of underwater vehicles. This paper presents a micro flexible caudal fin propulsor actuated by shape memory alloy (SMA) wires. To improve the responding frequency and fatigue of the SMA wires, a pair of slots is designed. So the SMA wires can be heated in the… (More)
STARIMAGER is a helicopter-borne high resolution digital Three-Line Scanner (TLS) imaging system developed by STARLABO Corporation jointly with the University of Tokyo and ETH-Hoenggerberg for large scale mapping, linear-shaped ground objects investigation (such as roads, rivers, railways, pipelines, etc.), and remote sensing applications. As with other… (More)
This paper presents a correlation of the commercial CAD/CAM software into the micro 4-axis electrical discharge milling (ED-milling) process. By applying the commercial CAD/CAM software, the model can be designed and the NC code can be generated. According to the NC code, the 4-axis ED-milling process can be carried out successfully by the micro 4-axis… (More)
