Abstract: In order to provide an unmanned aircraft capable of minimizing damage due to a crash caused by malfunction or the like during flight, a flight route is set on map information including a fall avoidance area, control is performed such that the aircraft flies on a set flight route, and information at each position during flight on the flight route is acquired in relation to the map information in real time to determine whether or not the aircraft is approaching the fall avoidance area. In a case where it is determined that the aircraft is approaching the fall avoidance area, control is performed so as to increase a flight speed.

Abstract: A robot arm that can be suitably used in aerial vehicles and an unmanned aerial vehicle equipped with the robot arm. The robot arm includes: an arm unit includes a plurality of joints; arm controlling means for controlling driving of the joints; and a displacement detector configured to detect a change of a position and inclination of the arm unit. The arm unit has a base end connected to the aerial vehicle. At least a leading end of the arm unit is exposed to an outside of the aerial vehicle. When the displacement detector has detected a position error that is an unexpected change of the position or inclination of the arm unit, the arm unit controlling means is configured to cause the joints to absorb the position error so as to prevent the position error from being transmitted to a side of the leading end of the arm unit.

Abstract: A motor driver for an outer-rotor sensorless brushless motor (hereinafter simply referred to as “motor”), the motor driver including: an external magnetic sensor; and a drive circuit. The external magnetic sensor is configured to detect a leakage flux of a permanent magnet of the motor at an outside of the motor, the permanent magnet being arranged on an inner circumferential surface of a rotor of the motor. The drive circuit is configured to control rotation of the motor based on: a control signal for the motor input into the drive circuit; and feedback input into the drive circuit from the external magnetic sensor.
