    摘要: A observation device includes an aircraft and an observation unit attached to the aircraft that observes a target within a predetermined view angle. The aircraft includes a base, at least two thrusters that generate a propulsion force including lift, actuators that change a direction of the propulsion force generated by the thrusters with respect to the base, an inertial measurement unit (IMU) that detects an orientation of the base with respect to a ground surface, and a controller that controls the thrusters and the actuators based on the orientation of the base detected by the IMU. The observation unit is fixedly attached to the base and the aircraft is configured to fly in any arbitrary orientation with respect to the ground surface through a combination of a magnitude of the propulsion force and the direction of the propulsion force of each of the thrusters.

    摘要: In an aerial vehicle, a malfunction determiner determines whether there is a malfunction in one of thrusters of the aerial vehicle. A flight controller activates the thrusters, and controls the output of each of the thrusters. The flight controller deactivates, when it is determined that there is a malfunction in one of the thrusters as a malfunctioned thruster, the malfunctioned thruster. The flight controller deactivates a selected thruster in the thrusters; the selected thruster being paired to the malfunctioned thruster, and controls the active thrusters except for the deactivated thrusters in all the thrusters to make the flight attitude of the aerial vehicle stable. The flight controller controls the active thrusters to cause the aerial vehicle to land while maintaining the flight attitude of the aerial vehicle being stable.

    摘要: Driving wheels and non-driving wheels are installed to a lower portion of a case body. The driving wheels are driven by drive devices, respectively. A control device controls a drive operation of the drive devices. An angle sensing device senses a tilt angle of the case body about a rotational axis of the driving wheels. In a case where the tilt angle of the case body, which is sensed with the angle sensing device, is equal to or larger than a predetermined tilt angle in a state where the driving wheels contact a ground while the non-driving wheels are lifted away from the ground, the control device controls the drive devices in such a manner that the case body is held in a self-standing state with the driving wheels while keeping the non-driving wheel away from the ground.

    摘要: A flying device includes a base, thrusters, an orientation detection unit, an abnormality detection unit, and an orientation control unit. The plurality of thrusters are provided on the base each including a propeller, a motor which drives the propeller, and a pitch change mechanism unit which changes a pitch of the propeller. The orientation detection unit detects an orientation of the base. The abnormality detection unit detects an abnormality in the thrusters. The orientation control unit, when the abnormality detection unit detects an abnormality in at least one of the thrusters, changes the pitches of the propellers in the remaining thrusters to maintain an orientation of the base detected by the orientation detection unit.
