    摘要: Computer-implemented methods, systems, and computer-readable storage media are disclosed to coordinate a plurality of devices in performing a task. A particular computer-implemented method includes storing updated status information at a device where the updated status information reflects a change in a vote for a task state of one or more of a plurality of devices. A first updated status message is sent to one or more of the plurality of devices where the first updated status message communicates the updated status information. A task consensus at the device is updated when the updated status information indicates that at least a predetermined quantity of the plurality of devices agrees on the task status.

    摘要: Method and systems for using agents to perform an operation (e.g., a search) over a geographic area are provided. The system can first create a digital map of the geographic region divided into cells that contain information about the progress of an operation related to the geographic region. Next, the system can calculate a distance gradient of the digital map. The distance gradient indicates the distance from cells of the digital map to the nearest unoperated cell. The system can determine the next move for each agent based on the distance gradient. Also described are methods and systems for efficiently exchanging digital map information among agents and for distributing agents to increase network coverage and decrease agent crowding.

    摘要: Systems and methods for closed-loop feedback control of controllable devices using motion capture systems are disclosed. In one embodiment, a system includes a motion capture system configured to measure one or more motion characteristics of one or more controllable devices as the one or more controllable devices are operating within a control volume. A processor receives the measured motion characteristics from the motion capture system and determines a control signal based on the measured motion characteristics. A position control system receives the control signal and continuously adjusts at least one motion characteristic of the one or more controllable devices in order to maintain or achieve a desired motion state. The controllable device may be equipped with passive retro-reflective markers. The motion capture system, the processor, and the position control system comprise a complete closed-loop feedback control system.

    摘要: A distributed tempero-spatial query service uses a plurality of service agents each having an assigned area of responsibility. The service agents are organized into a spatial hierarchy based upon each service agent's area of responsibility. The spatial hierarchy is distributed and hosted on each of the service agents. The spatial hierarchy enables matching of requests from subscribing agents with publishing agents based upon spatial attributes. The spatial hierarchy is dynamically maintained in a distributed manner on each of the service agents. The service agents can be arranged into a tree-based spatial hierarchy having a limited depth.
