Abstract

A system in accordance with the present invention tasks a team of autonomous unmanned vehicles. The system includes a first team member and a second team member. The first team member has a first level of autonomy. The second team member has a second level of autonomy. The first level of autonomy is different than the first level of autonomy. The first team member is given instructions corresponding to the first level of autonomy. The second team member is given instructions corresponding to the second level of autonomy.

Claims

1. A system for tasking a team of a plurality of unmanned vehicles executing a mission plan, each of the plurality of unmanned vehicles having an associated set of resources and an associated level of autonomy, said system comprising:

a planning information manager configured to receive the mission plan, translate information from the mission plan into a desired format, and provide updates of objectives to the mission plan;

a mission planner configured to receive the formatted information from the planning information manager, formulate a plurality of mission tasks from the formatted information, and determine an optimal allocation of a selected set of the plurality of unmanned vehicles to the plurality of mission tasks according to the respective associated resources and level of autonomy of the plurality of unmanned vehicles; and

a user interface manager configured to communicate a set of instructions to each of the selected set of the plurality of unmanned vehicles, the set of instructions for each unmanned vehicle comprising a minimum set of instructions associated with the level of autonomy of the unmanned vehicles.

2. The system as set forth in claim 1 wherein said mission planner transmits the update to a mission task resource allocator.

3. The system as set forth in claim 1 wherein said mission planning manager transmits the update to a choke point monitor.

4. The system as set forth in claim 1 wherein said mission planning manager transmits the update to a terrain route planner.

5. The system as set forth in claim 1 wherein said mission planning manager transmits the update to a trajectory planner.

6. The system as set forth in claim 1 further including an embedded simulator for modeling a candidate mission plan.

7. The system as set forth in claim 1 further including a repository for storing realistic models.

8. The system as set forth in claim 1 further including an operator interface manager for monitoring execution of the mission plan.

9. The system as set forth in claim 1 further including a platform execution manager for evaluating the mission plan.

10. The system as set forth in claim 9 wherein said platform execution manager has a task sequencer and a vehicle platform translator.
