Claim 0:
1. A drone comprising:
a main body;
a plurality of blades mounted on the main body;
a plurality of driving motors corresponding to the respective blades in order to rotate the blades;
a power supply unit configured to supply power to the driving motors;
a control unit configured to control power supplied from the power supply unit to the driving motors in order to control flight of the main body;
a plurality of sensors installed to correspond to the respective blades in order to detect an obstacle close to the blades by measuring signals; and
a plurality of switch units configured to receive a signal detected by one of the sensors and turn on and off direct supply of power to a corresponding one of the driving motors so that the power supply unit can increase output of the driving motor;
wherein the switch units are connected to turn on and off power supplied to the driving motor that drives a blade corresponding to the sensor so that the main body does not collide with the obstacle,
wherein a corresponding one of the switch units is turned on to increase the output of the driving motor when a difference between signal values detected by sensors corresponding to symmetrical blades is equal to or larger than a set value.
