工业技术院电子技术综合研究所试制了在无重力的宇宙空间能够把小物件牢牢固定住的装置。这个装置象海葵那样自动收缩四指,抓住让它捕获的物体。利用形状记忆合金作指的驱动源。美国、日本、欧洲航天局和加拿大在共同实施太空站建设计划,但是没有提出任何有关小物件抓取装置的提案,所以这个装置引起有关方面的注目。试作的装置有四指,指长12厘米。为了使装置轻量化,使用铝合金制作。与人指一样,各指有三个关节,两根 Institute of Industrial Technology, Institute of Electronic Technology trial production of non-gravity space can be small objects firmly fixed device. This device automatically shrinks four fingers like an anemone, grabbing the object it caught. The use of shape memory alloy as the driving source. The United States, Japan, the European Space Agency and Canada are jointly implementing the space station construction plan, but did not put forward any proposals on small object gripping devices, so this device has attracted the attention of the parties concerned. Trial device has four fingers, refers to the length of 12 cm. In order to make the device lighter, the use of aluminum alloy production. Like the human finger, each finger has three joints, two
