Abstract:
This disclosure describes an automated mobile vehicle that includes one or more distance determining elements configured to detect the presence of objects and to cause the automated mobile vehicle to alter its path to avoid the object. For example, a distance determining element may be incorporated into one or more of the motors of the automated mobile vehicle and configured to determine a distance to an object. Based on the determined distance, a path of the automated mobile vehicle may be altered.
Abstract:
UAV configurations and battery augmentation for UAV internal combustion engines, and associated systems and methods are disclosed. A representative configuration includes a fuselage, first and second wings coupled to and pivotable relative to the fuselage, and a plurality of lift rotors carried by the fuselage. A representative battery augmentation arrangement includes a DC-powered motor, an electronic speed controller, and a genset subsystem coupled to the electronic speed controller. The genset subsystem can include a battery set, an alternator, and a motor-gen controller having a phase control circuit configurable to rectify multiphase AC output from the alternator to produce rectified DC feed to the DC-powered motor. The motor-gen controller is configurable to draw DC power from the battery set to produce the rectified DC feed.
Abstract:
The present invention discloses a method and apparatus for modifying an aircraft state in real time. The method comprises: obtaining historical state information of a image capturing unit, a current image shot by the image capturing unit and an historical image preceding the current image, and currently-measured external information or internal information sensed by at least one kind of sensor; predicting a matching characteristic point in the current image corresponding to a target characteristic point in the historical image according to the historical state information, and calculating, from the matching characteristic point, current external information or internal information of the image capturing unit; calculating a relative proportional relationship between the external information of the image capturing unit and the external information of said at least one kind of sensor, or between the internal information of the image capturing unit and the internal information of said at least one kind of sensor, according to a predetermined positional relationship of said at least one kind of sensor relative to the image capturing unit; and modifying current state information of the image capturing unit estimated from the historical state information, by using the relative proportional relationship. The present invention is implemented to modify state information of the aircraft and reduce a deviation.
Abstract:
An unmanned aerial vehicle system according to the present invention includes a housing (2000) mounted on a vehicle (10) and having an inner space, the housing provided with a launching unit, an unmanned aerial vehicle (1000) accommodated in the housing and configured to be launched from the housing when a driving state of the vehicle meets a preset condition, wing units (1210) mounted to the unmanned aerial vehicle and configured to allow the flight of the unmanned aerial vehicle in response to the launch from the housing, an output unit disposed on the unmanned aerial vehicle, and a controller configured to control the wing units to move the unmanned aerial vehicle to a position set based on information related to the driving state when the unmanned aerial vehicle is launched, and control the output unit to output warning information related to the driving state.
Abstract:
Provided herein are systems and method for autonomously or semi-autonomously landing an unmanned aerial vehicle (UAV) on a landing pad. The landing pad can include features configured to correct misalignment of the UAV on the landing pad. The landing pad can additionally include one or more markers than can be identified by the UAV to aid the UAV in locating the landing pad and determining the location of the UAV relative to the landing pad.
Abstract:
Systems, methods, and devices are provided for providing flight response to flight-restricted regions. The location of an unmanned aerial vehicle (UAV) may be compared with a location of a flight-restricted region. If needed a flight-response measure may be taken by the UAV to prevent the UAV from flying in a no-fly zone. Different flight-response measures may be taken based on the distance between the UAV and the flight-restricted region and the rules of a jurisdiction within which the UAV falls.
Abstract:
A method for controlling a path of a rotary-wing drone 1, characterized in that said method comprises steps for: • Establishing a first-order temporal relation between flight control parameters and flight dynamics for said rotary-wing drone 1 comprising: o An Explicit Discrete Time-Variant State-Space Representation of a translation control of said rotary-wing drone 1; o An Explicit Discrete Time-Variant State-Space Representation of a course control of said rotary-wing drone 1; • Controlling the path of said rotary-wing drone 1 by: o Estimating a course 17 of said rotary-wing drone 1 on the basis of said Explicit Discrete Time-Variant State-Space Representation of a course control of said rotary-wing drone 1; o Estimating a position 18 of said rotary-wing drone 1 on the basis of said Explicit Discrete Time-Variant State-Space Representation of a translation control of said rotary-wing drone 1; said steps of estimating being performed independently.
Abstract:
Le corps de drone (10) comprend un châssis (12), solidaire de bras (14) de liaison à des blocs propulseurs (16), une carte électronique (24) portant des composants ainsi que des capteurs accélérométriques, inertiels et altimétriques, un support pour cette carte, et une interface élastique (26) entre châssis et support de carte, pour filtrer et absorber les vibrations mécaniques. Le support de la carte est une platine (22) en matériau métallique électriquement conducteur. La platine porte sur un côté verso des plages thermiquement conductrices en des emplacements situés en vis-à-vis de composants électroniques dissipateurs de chaleur montés sur la carte côté verso. La platine est par ailleurs électriquement reliée à un potentiel de masse de la carte de manière à former écran de blindage électromagnétique. Elle est en outre mécaniquement reliée au châssis avec découplage par l'interface élastique (26) interposée entre la platine et le châssis.
