A movable object according to an embodiment of the present technology includes a body unit, a notification unit, and a notification control unit. The notification unit is provided in the body unit. The notification control unit controls an operation of the notification unit, to thereby notify of information regarding at least one of an orientation of the body unit or a position on the body unit as assistance information for assisting work of a user on the movable object. This enables the user to intuitively recognize which orientation the user should put the body unit in, and the workability in user's work can be improved.

In some embodiments, a computer-implemented method for managing resources of a fleet of unmanned aerial vehicles (UAVs) is provided. A computing system creates a mission record and one or more candidate records. Each candidate record of the one or more candidate records represents one or more resources for accomplishing a mission represented by the mission record. The computing system adds a mission node representing the mission record to a resource competition network graph (RCN graph). The computing system adds one or more candidate nodes representing the one or more candidate records to the RCN graph. The computing system determines an optimized allocation of candidate records to mission records using at least a subgraph of the RCN graph. A candidate record is determined to commit to a mission record, and the computing system updates the RCN graph to commit the candidate record to the mission record.

A method for flight control of an aircraft with multiple actuators during flight is disclosed. For each actuator, a control command is computed according to at least one predetermined control law and based on pilot inputs and sensor measurements in relation to a physical state of the aircraft. The respective control commands are provided to the actuators. The control commands are independently monitored by estimating or measuring a current physical state of the aircraft and comparing it with the control commands. This comparison includes checking whether the control commands stabilize the aircraft in a stable state in the absence of both disturbances and pilot inputs according to at least one predefined criterion. If the monitoring indicates a lack of stability, transmission of the control commands is prevented and a backup control command is computed for each actuator.

The present disclosure discloses a method for attitude control of a quadrotor UAV, comprising establishing an attitude dynamics model of the quadrotor UAV, establishing a motion equation and a state-space equation of a UAV control system, determining an LADRC-CFO, and establishing a differential tracker for reducing a system overshoot.

A vehicle control framework enables improved attitude tracking and mode switching of a vehicle by modeling the vehicle as a switched system, where the vehicle is operable for changing a geometric configuration during flight. The vehicle control framework implements a control law that accommodates modeling uncertainties and unknown external disturbances. The vehicle also enforces a switching time constrained by a minimum dwell time which can be adaptively updated based on attitude errors.

An unmanned aerial vehicle includes: a mooring member capable of mooring an article; a linear member connected to the mooring member; a reel around which the linear member is wound. The unmanned aerial vehicle acquires information relating to wind strength around the article when the article is to be lowered from the unmanned aerial vehicle by controlling the reel; and controls the reel so as to provide a feeding amount of the linear member in dependence on the wind strength, on the basis of the acquired information.

In a delivery system S including an UAV 1 and a management server 2, the UAV 1 controls at least a position and/or an orientation of the UAV 1 so that a package placed in a release location and a peripheral region of the package fall within an angle of view of a camera. And then, the UAV 1 saves, as an image that proves delivery completion of the package, an image of the peripheral region including the package captured by the camera in a storage unit 15 of the UAV 1 or a storage unit 22 of the management server 2.

An aerial vehicle includes a center body, two arm assemblies arranged at the center body, a power device, and a driver mechanism mechanically coupled to the arm assemblies. The power device includes two first and two second rotor power assemblies. Each pair of first and second rotor power assemblies are installed at two ends of an arm assembly. The driver mechanism drives the arm assemblies to move relative to the center body such that distal parts of the two arm assemblies move between first and second height positions. In a direction of a roll axis of the power device, the first rotor power assemblies are closer to an installation site on the center body than the second rotor power assemblies. When the distal parts are at the second height position, spacing between the first rotor power assemblies is larger than spacing between the second rotor power assemblies.
