Unmanned vehicle, system and method for correcting a trajectory of an unmanned vehicle

An unmanned vehicle for use with a companion unmanned vehicle, comprising:

• a position unit that is configured to determine a current position of the unmanned vehicle;
• a memory unit that is configured to store a planned path of the unmanned vehicle;
• and
• a control unit disposed in communication with the position unit and the memory unit, the control unit configured to:
• determine that the unmanned vehicle is off-course based on at least a difference of the current position of the unmanned vehicle and the planned path assigned to the unmanned vehicle;
• generate a delay and a corrected path for the unmanned vehicle;
• communicate at least the delay and the corrected path to the companion unmanned vehicle;
• and
• control a movement of the unmanned vehicle such that the unmanned vehicle moves along the corrected path after the delay,
• wherein the delay is a time delay, which provides the unmanned vehicle with a period of time before a change is initiated in the first trajectory of the unmanned vehicle to a second trajectory, and
• wherein the time delay is at one of an indefinite delay, a predetermined time delay and specific time period delay before the change is initiated and the unmanned vehicle travels along the corrected path absent any interruptions.

A system, comprising:

• a plurality of unmanned vehicles spaced from each other, each of the plurality of unmanned vehicles including:
• a position unit configured to determine a current position of the unmanned vehicle;
• and
• a memory unit configured to store a planned path of the unmanned vehicle;
• and
• a controller disposed in communication with the each of the plurality of unmanned vehicles, the controller configured to:
• receive the current position and the planned path of each of the plurality of unmanned vehicles;
• determine that at least one unmanned vehicle is off-course based on at least a difference of the current position and the planned path of each of the plurality of unmanned vehicles;
• generate a delay and a corrected path for the at least one unmanned vehicle;
• communicate at least the delay and the corrected path to each of the plurality of unmanned vehicles;
• and
• control a movement of the at least one unmanned vehicle such that the at least one unmanned vehicle moves along the corrected path after the delay,
• wherein the delay is a time delay, which provides the unmanned vehicle with a period of time before a change is initiated in the first trajectory of the unmanned vehicle to a second trajectory, and
• wherein the time delay is at one of an indefinite delay, a predetermined time delay and specific time period delay before the change is initiated and the unmanned vehicle travels along the corrected path absent any interruptions.
