摘要:
A method plans paths of a set of mobile sensors with changeable positions and orientations in an environment. Each sensor includes a processor, an imaging system and a communication system. A desired resolution of coverage of the environment is defined, and an achieved resolution of the coverage is initialized. For each time instant and each sensor, an image of the environment is acquired using the imaging system. The achieved resolution is updated according to the image. The sensor is moved to a next position and orientation based on the achieved resolution and the desired resolution. Then, local information of the sensor is distributed to other sensors using the communication system to optimize a coverage of the environment.

A method and apparatus for identifying a number of diameters for a group of trees. An unmanned aerial vehicle moves on a route through the group of trees at a height that is configured to allow measurement of the number of diameters for the group of trees by a sensor system associated with the unmanned aerial vehicle. Information is generated about the number of diameters for the group of trees using the sensor system associated with the unmanned aerial vehicle.

Standardized distance minima for longitudinal separation is ensured during flight of a second aircraft behind a first aircraft on take-off or landing of the aircraft on one runway or on two parallel runways located near to each other, or during flight one behind the other at near altitude levels in conditions where there is the risk of turbulence from the vortex wake of the first aircraft possibly being present along the direction of movement of the second aircraft. Continuous monitoring of the level of wake vortex flight safety of the second aircraft is carried out in a buffer zone which surrounds the aircraft and is selected on the basis of the direction of the aircraft outside the standardized distance minimum, taking into account pilot reaction time and the time for the system for controlling the second aircraft to respond to a command to change speed.
摘要:
A system for flock-based control of a plurality of unmanned aerial vehicles (UAVs). The system includes UAVs each including a processor executing a local control module and memory accessible by the processor for use by the local control module. The system includes a ground station system with a processor executing a fleet manager module and with memory storing a different flight plan for each of the UAVs. The flight plans are stored on the UAVs, and, during flight operations, each of the local control modules independently controls the corresponding UAV to execute its flight plan without ongoing control from the fleet manager module. The fleet manager module is operable to initiate flight operations by concurrently triggering initiation of the flight plans by the multiple UAVs. Further, the local control modules monitor front and back and communication channels and, when a channel is lost, operate the UAV in a safe mode.

Methods and apparatus to cooperatively lift a payload are disclosed. An example method to control a lift vehicle includes determining a first positional state of the lift vehicle with respect to a payload controlled by a plurality of lift vehicles including the lift vehicle, determining a second positional state of the lift vehicle with respect to a goal location, detecting distances to the other ones of the plurality of lift vehicles, determining a third positional state of the lift vehicle based on the distances to the other ones of the plurality of lift vehicles, and calculating a control command to control the lift vehicle based on the first positional state, the second positional state, and the third positional state.

Embodiments described herein may help to provide medical support via a fleet of unmanned aerial vehicles (UAVs). An illustrative medical-support system may include multiple UAVs, which are configured to provide medical support for a number of different medical situations. Further, the medical-support system may be configured to: (a) identify a remote medical situation, (b) determine a target location corresponding to the medical situation, (c) select a UAV from the fleet of UAVs, where the selection of the UAV is based on a determination that the selected UAV is configured for the identified medical situation, and (d) cause the selected UAV to travel to the target location to provide medical support.
摘要:
A system and method are provided for controlling a plurality of vehicles to affect positioning of a common payload. The system comprises of multiple vehicles having positioners to change the location of the common payload, where the group of vehicles form a swarm that is controlled by a driver or pilot station. Each vehicle is autonomously stabilized and guided through a swarm electronics unit, which further includes sensor, communication, and processing hardware. At the driver or pilot station, a system or a person remotely enters payload destinations, which is processed and communicated to each vehicle. The method for controlling a multi-vehicle system includes inputting the desired location of the payload and determining a series of intermediary payload waypoints. Next, these payload waypoints are used by the swarm waypoint controller to generate individual waypoints for each vehicle. A controller for each vehicle moves the vehicle to these individual waypoints.
摘要:
A system and method of coordination of aerial vehicles through a central server are disclosed. In one embodiment, a system includes a central server and an Internet protocol network. A first aerial vehicle is communicatively coupled with the central server through the Internet protocol network and a second aerial vehicle is communicatively coupled with the first aerial vehicle when a command is transferred through the central server using the Internet protocol network. A first computing device of a first user of the first aerial vehicle operatively controls the first aerial vehicle and a second computing device of a second user of the second aerial vehicle operatively controls the second aerial vehicle. At least one of the first computing device of the first user and the second computing device of the second user communicate the command to the first aerial vehicle through the central server.
