aims at developing swarms of flying robots that can be deployed in disaster areas to rapidly create communication networks for rescuers. Flying robots are interesting for such applications because they are fast, can easily overcome difficult terrain, and benefit from line-of-sight communication.

The Special Project for Earthquake Disaster Mitigation in Urban Areas (2002-2006) conducted by the Earthquake Research Institute at the University of Tokyo. The project revealed the detailed geometry of the subducted Philippine Sea plate (PSP) beneath the Tokyo Metropolitan area and improved information needed for seismic hazards analyses of the largest urban centers. In 2007 the Special Project for Earthquake Disaster Mitigation in Tokyo Metropolitan Area started focusing at  the vertical proximity of the PSP down going lithospheric plate and the risks for the greater Tokyo urban region that has a population of 42 million and is the center of approximately 40 % of the nation's activities. A M 7 or greater (M 7+) earthquake in this region at present has high potential to produce devastating loss of life and property with even greater global economic repercussions. The Central Disaster Management Council of Japan estimated that a great earthquake in the region might cause 11,000 fatalities and 112 trillion yen (1 trillion US$) economic loss. The Earthquake Research Committee of Japan estimated a probability of 70 % in 30 years for a great earthquake in this region. 

Instead of calling CrazyFlie (as it's known) a tiny quadcopter, it might be more accurate to just describe it as a PCB that happens to also be able to launch itself into the air. Measuring a scant 10 centimeters per side, CrazyFlie uses its PCB as a primary structural component, which helps keep the size and weight to a minimum... In total, we're talking about only 20 grams. Despite its tinyness, the quadcopter includes a charging port, radio, 3-axis accelerometer, two gyroscopes, and a lightweight 110 mAh LiPO battery that gives it about four and a half minutes of flying time:
