Patent attributes
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.
