PROBLEM TO BE SOLVED: To provide an unmanned flight body having relatively low probability of damage due to crash caused by power shortage of a mounted battery.SOLUTION: An unmanned flight body drives a motor 12 by power of a battery 11 for rotating a rotor, and makes the unmanned flight body float and fly. A control part 14 performs (a) risk avoidance control when any one of output voltage, output current, and output power of the battery 11 becomes less than a predetermined threshold in flight. The risk avoidance control contains rising prohibition control of the unmanned flight body or autonomous drop control of the unmanned flight body, and the above-mentioned battery is a secondary battery. The control part adjusts the above-mentioned predetermined threshold according to a charging number of the battery.SELECTED DRAWING: Figure 1
【課題】 搭載電池の電力不足に起因する墜落による損傷の可能性が比較的小さい無人飛行体を得る。【解決手段】 無人飛行体は、電池11の電力でモーター12を駆動してローターを回転させ、当該無人飛行体を浮上、飛行させる。制御部14は、(a)飛行中において電池11の出力電圧、出力電流、および出力電力のいずれかが所定の閾値未満になったときに危険回避制御を行う。この危険回避制御は、当該無人飛行体の上昇禁止制御または当該無人飛行体の自律降下制御を含み、上述の電池は、2次電池であり、制御部は、電池の充電回数に応じて上述の所定の閾値を調整する。【選択図】 図1
