摘要： Various embodiments include methods, devices, and systems of transporting a payload using a robotic vehicle. The methods may determine whether a payload has separated from the robotic vehicle and take a corrective action in response to determining that the payload is not securely held by the robotic vehicle.

摘要： An adjustment device for adjusting the position of the center of gravity of an aircraft, the aircraft having at least two thrust production units that contribute at least to providing the aircraft with lift, the adjustment device comprising at least one heavy member that is movable relative to an airframe of the aircraft and also at least one actuator for causing the heavy member to move. The adjustment device includes an avionics system configured to detect a failure of any one of the thrust production units and, in the presence of such a failure, to control the at least one actuator to cause the heavy member to move.

摘要： A method for controlling a flying projectile which rotates during flight, comprising: determining an angle of rotation of an inertial mass spinning about an axis during flight; and controlling at least one actuator for altering at least a portion of an aerodynamic structure, selectively in dependence on the determined angle of rotation and a control input, to control aerodynamic forces during flight. An aerodynamic surface may rotate and interact with surrounding air during flight, to produce aerodynamic forces. A sensor determines an angular rotation of the spin during flight. A control system, responsive to the sensor, produces a control signal in dependence on the determined angular rotation. An actuator selectively alters an aerodynamic characteristic of the aerodynamic surface in response to the control signal.

摘要： The invention relates to an aircraft having a tailless fuselage. The fuselage has a body which includes a transverse trailing edge. The aircraft further includes a wing having two sides which protrude from opposite sides of the fuselage. The body typically has a fineness ratio of between 3 and 7. Each side of the wing has an inner section having a first dihedral angle and an outer section having a second dihedral angle, the second dihedral angle being less than the first dihedral angle. At least part of the outer section is typically swept back. The configuration of the aircraft provides it with improved flight efficiency.

摘要： The present application provides an unmanned aerial vehicle (UAV) for a long duration flight. An exemplary UAV may include a UAV body assembly. The UAV may also include a flight control system (FCS) coupled to the UAV body assembly. The UAV may further include a motor coupled to the UAV body assembly at one end and coupled to a propeller at the other end. The FCS is communicatively connected to the motor. A center of gravity (CG) of the UAV is at a point between 21% and 25% of a mean aerodynamic chord (MAC) of the UAV.

摘要： An autonomous cargo container retrieval and delivery system locates a select cargo container and maneuvers an unmanned aerial vehicle proximate to the container for retrieval. The vehicle positions itself to engage the cargo container using a grasping mechanism, and, responsive to engaging the cargo container, retracts the cargo container toward the vehicle. As the cargo container is retracted toward the vehicle, weight sensors within the retrieval mechanism sense the weight and the weight distribution of the cargo container, and, can modify the cargo container's location on the vehicle to optimize vehicle flight operations or replace the container on the ground and alert the operator that the cargo container is too heavy or has an improper weight distribution. Upon mating the cargo container with the vehicle, a coupling mechanism latches or secures the cargo container to the vehicle for further flight and/or ground operations.

摘要： An aeronautical vehicle that rights itself from an inverted state to an upright state has a self-righting frame assembly has a protrusion extending upwardly from a central vertical axis. The protrusion provides an initial instability to begin a self-righting process when the aeronautical vehicle is inverted on a surface. A propulsion system, such as rotor driven by a motor can be mounted in a central void of the self-righting frame assembly and oriented to provide a lifting force. A power supply is mounted in the central void of the self-righting frame assembly and operationally connected to the at least one rotor for rotatably powering the rotor. An electronics assembly is also mounted in the central void of the self-righting frame for receiving remote control commands and is communicatively interconnected to the power supply for remotely controlling the aeronautical vehicle to take off, to fly, and to land on a surface.

摘要： A method of controlling an unmanned aerial vehicle includes receiving a first signal including information relating to a payload of the unmanned aerial vehicle, retrieving a predetermined value from a memory of the unmanned aerial vehicle based on the information of the first signal, and generating a second signal for changing a configuration of an arm of the unmanned aerial vehicle to change a distance of at least one of a plurality of propulsion units of the unmanned aerial vehicle corresponding to the arm from a reference point on a central body of the unmanned aerial vehicle based on the predetermined value.

摘要： The present invention is to provide a system, a method, and a program for adjusting the balance of an insect killer hung from a robot that are capable to adjust the position of the insect killer. The system for adjusting the balance of an insect killer 1 hung from a robot 10 moving by a propeller 410 through a support arm 100 adjusts the balance of the insect killer 200 so that the angle between the support arm 100 and the direction of gravitational force from the robot 10 has a predetermined value or more; and adds a weight 300 to an end of the same support arm 100 as the support arm 100 in the negative direction to an angle of the predetermined value and calculates the weight 300 to adjust the balance of the insect killer 200.

摘要： An aerial system includes a body, a propeller coupled to the body, and a motor coupled to the propeller. The motor is configured to rotate the propeller in a first direction, wherein an other portion of the aerial system rotates in an opposing second direction. The other portion of the aerial system that rotation in the opposing second direction may be the body or a second propeller. The aerial system also includes a processing system configured to control the motor to cause the aerial system to hover in a substantially fixed pose, and a camera configured to obtain images of an environment proximate the aerial system while the aerial system is hovering.
