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, the rising prohibition control allows control for movement in a latitude direction and in a longitude direction, and does not increase altitude of the unmanned flight body, by restricting an operation of the motor.SELECTED DRAWING: Figure 1 |
