There are approximately 700,000 bridges which are bridges of 2[m] over a bridge length in Japan. At intervals of once every five years, it is necessary to inspect the bridge. That is, it is necessary to inspect the bridge 140,000 per year. In addition, reduction of experts bridge a decrease in tax revenues due to declining birthrate and aging population is a problem. Therefore in this research reports on flight experiments to build a control algorithm to fly by avoiding contact with the structure semi-autonomously implement the sensor to a multi-copter for the purpose of detection of cracks in the space under the bridge.
