研制太阳能卫星这样的空间巨型发射天线技术是当前航天领域的重要课题之一。这种巨大的天线在太空中有许多有用的应用，例如移动电话的通信天线，遥感雷达，导航和观测等。我们建议使用带机器人的Furoshiki卫星来建造这种巨大的结构。在使用与巨大天线相同大小的Furoshiki卫星部署大型网络后，所有天线元件都用自己的腿在网络上向其分配的位置爬行，以实现巨大的天线。计划使用ISAS的探空火箭进行微重力实验，以证明部署大网的可行性和相控阵性能。三颗子卫星正在与具有弱弹簧的母卫星分离，并且子卫星将Furoshiki网展开为约20- 40米大小的三角形形状。在部署期间，通过安装在母卫星和子卫星上的几个照相机观察子卫星和网络的动态，同时在地面站使用反向方法测量相控阵天线的性能。最后，两个微型机器人从母卫星爬到网上的某些点，以展示一种有前途的方法来构建射频发射机面板。这些机器人是由NASA、ESTEC和科比大学在国际上开发的。对于微重力环境下的网络爬行机器人，有很多不同的设想。每个组织都在独立开发不同类型的机器人。科比大学正试图开发一种轮子，通过捏住网的线来在网上运行。它可以成功地在网络上运行，但问题是发现字符串缠结。在我们的演讲中主要描述了科比大学的机器人。
It is one of the most important and critical issues to develop a technology to construct space huge transmitting antenna such as the Solar Power Satellite. The huge antenna have many useful applications in space, for example, telecommunication antennas for cellular phones, radars for remote sensing, navigation and observation, and so on. We are proposing to apply the Furoshiki satellite with robots to construct the huge structures. After a large web is deployed using the Furoshiki satellite in the same size of the huge antenna, all of the antenna elements crawl on the web with their own legs toward their allocated locations in order to realize a huge antenna. The micro-gravity experiment is planned using a sounding rocket of ISAS in order to demonstrate the feasibility of the deployment of the large web and the phased array performance. Three daughter satellites are being separated from the mother satellite with weak springs, and the daughter satellites deploy the Furoshiki web to a triangular shape at the size of about 20-40m. The dynamics of the daughter satellites and the web is observed by several cameras installed on the mother and daughter satellites during the deployment, while the performance of the phased array antenna using the retrodirective method will simultaneously be measured at the ground station. Finally two micro robots crawl from the mother satellite to the certain points on the web to demonstrate one promising way to construct RF transmitter panels. The robots are internationally being developed by NASA, ESTEC and Kobe University. There are many various ideas for the robots to crawl on the web in the micro-gravity. Each organization is independently developing a different type of the robots. Kobe University is trying to develop wheels to run on the web by pinching the strings of the web. It can successfully run on the web, though the issue is found to tangle the strings. The robot of Kobe University is mainly described in our presentation.
