Fecha de publicación: 13/12/2007 Fuente: WIPO "swarm" A cooperative swarm of unmanned vehicles includes a plurality of unmanned vehicles, each having a location identification system operable to provide location coordinates; a transceiver operable to send and receive location coordinates via omnipresent signals of opportunity, and a guidance system operable to selectively guide the unmanned vehicle towards an identified target and a specified location within an environment. Access to omnipresent signals of opportunity facilitates transmissions indicative of the identified target and/or location between unmanned vehicles in an environment, e.g., an urban environment, where direct line of sight contact is limited. In a related method, at least one omnipresent signal of opportunity is detected within an environment. Location coordinates are transmitted between unmanned vehicles via the detected signal. Collective evaluation facilitates identification of a target within the environment and, and responsive to such identification, at least a subset of the unmanned vehicles are moved to the target's location.
