摘要： A method for controlling the movement of agents using local communications is provided. Generally, each agent maintains an optimal distance from other local neighbor agents by, for each agent 200, selecting a local agent 202, measuring the distance and angle to the agent 204, performing a distance maintenance calculation 218, and repeating the distance maintenance calculation 218 for each local agent. In the distance maintenance calculation 218, an attraction/repulsion map is used in order to determine whether an agent is attracted to or repelled from other agents. A motion vector is used to determine agent responses to the attraction or repulsion. Over time, the agents settle into a neutral configuration where each is optimally distanced from the other agents. Reference agents and leader agents can be designated to direct the movement of other agents, and agents can be designated as blocking beacons to repel other agents from undesirable areas.

摘要： A method, an apparatus, and a computer program product for facilitating local signaling among a plurality of agents are presented. An agent 100 including a digital processor 102 a transmitter 104, and a directional receiver 106 comprising a plurality of angular regions 108 is configured to enable the selection of a signal from a plurality of signals received on the basis of local data such as the strength of the received signal. The local data may be incorporated into a cumulative data portion of a signal that is passed from local agent 100 to local agent 100 across a plurality of agents 100 in order to provide a gradient across the plurality of agents 100. The gradient could be used, for example, to determine a shortest path across the agents. The signaling techniques described can also be used to determine the distance and direction to objects in the signaling path.

摘要： A method and apparatus for computing properties of a physical environment is provided, using a plurality of agents forming a distributed network embedded within the environment. The method comprises determining an initiating agent 200, transmitting a signal including a cumulative cost value to neighboring agents 202, and processing the signal at each neighboring agent to augment the cumulative cost value with local information 204. If multiple signals are received, determining which has the best cumulative cost value for generating a new signal 206, then treating the neighboring agent as an initiating agent 208 and transmitting the new signal to neighboring agents 208 and retaining the best augmented cost value in memory 210. Methods further include determining paths using shortest path computations, using dual gradients for aligning agents on a path between two reference agents, and discovering and converging agents on choke points.

摘要： An apparatus configured to obtain, process, and relay data to a user in a coherent and useful manner. An active fiducial is equipped with an interface for receiving and transmitting data. The fiducial may transmit its position using a satellite-based position sensing device such as a GPS. Active fiducials may also be equipped with battery power pack regenerated with solar cells. Similarly, the fiducials can be equipped with at least one video camera or other device having a focal plane array and a computer software system, configured to recognize shapes. The fiducials may also be equipped with inductive coils or other means for sensing metal containing compounds. The active fiducials may be equipped with a gas chromatograph. The active fiducials may use a variety of propulsion means including motor driven tracks, motor driven wheels, propellers, or other device or a combination of devices.
