Description

TECHNICAL FIELD

The embodiments disclosed herein are related to the field of autonomous vehicles, and more particularly when used as a system for herding animals.

BACKGROUND

An autonomous vehicle is an unmanned vehicle that is generally capable of sensing its environment and navigating without input from a driver. An autonomous vehicle may perform autonomous driving by recognizing and determining surrounding environments through various sensors attached to the autonomous vehicle. Further, an autonomous vehicle may enable a destination to be set and move to the set destination via autonomous driving.

Herding is the act of bringing individual animals together into a group, maintaining the group, and moving the group from place to place—or any combination of those. Herding is used in agriculture to manage domesticated animals. Herding can be performed by people or trained animals such as herding dogs that control the movement of livestock under the direction of a person.

As illustrated in FIG. 2, there is an identified need to herd a group of animals 100 that move about a pasture 102, such as a lea, grasslands, and the like for grazing, feeding, exercise and the like. The group of animals 100 may be of cattle, sheep, llamas, alpacas, goats, bison, or any other animals that move about in herds for socialization, safety, and grazing. In order to control and move a group of animals 100, human labor, in the form or ranch hands or cowboys, would move the herds, or trained animals, such as dogs, would be used to move these animals. However, an autonomous herding system 110 utilizing autonomous vehicles 10 may be used to herd the group of animals 10 without endangering ranch hands, working animals, and the like.

FIG. 2 illustrates a first embodiment of a herding system 110 for herding a group of animals 100. The herding system 110 includes a master autonomous vehicle 10a, and a plurality of client autonomous vehicles 10b that surround the group of animals 100 in pasture 102. The master autonomous vehicle 10a includes the master controller 32a that controls the herding system 110. As illustrated in FIG. 1, each autonomous vehicle 10 used as part of the herding system 110 may further include a camera 34 for taking images of the group of animals 100 and the pasture 102. The camera 34 may be a thermal imaging camera in order to best identify each animal 130 in the group of animals 100. A ranging unit 36 is provided for determining distance to the group of animals 100 and objects 104 in the pathway of the herding system 110 that need to be avoided, such as a tree illustrated in FIG. 2. The ranging unit 36 may be any unit known in the art such as a radar or LIDAR unit. Further, a global positioning system (“GPS”) unit 38 is provided for determining the position of the herding system. The camera 34, ranging unit 36, and GPS unit 38 for each autonomous vehicle 10 are in electronic communication with the master controller 32a of the master autonomous vehicle 10a to make course decisions for the herding system 110.

The herding system 110 further includes a plurality of client autonomous vehicles 10b. Each of the client autonomous vehicles 10b is operated to maintain a specific formation, with each of the client autonomous vehicles 10b and the master autonomous vehicle 10a specified distances d from and positions relative to each other. In the embodiment illustrated in FIG. 2, the herding system 110 includes four (4) client autonomous vehicles 10b, which when in formation with the master autonomous vehicle 10a maintain a pentagon-shaped formation. The number of client autonomous vehicles 10b may be varied by the required size of the herding system 110 to herd properly the group of animals 100.

Each of the client autonomous vehicles 10b, as illustrated in FIG. 2, include a client controller 32b that is in communication with the master controller 32a of the master autonomous vehicle 10a. The master controller 32a and each client controller 32b may communication wirelessly. The master autonomous vehicle may have a master communication unit 40a in electric communication unit with the master controller 32a, and each of the client autonomous vehicles 10b may include a client communication unit in electronic communication with the client controller for the respective client autonomous vehicles 10b. The master communication unit 40a and each of the client communication units 40b operate under a protocol selected from the group comprising Bluetooth, BLE, ZigBee, Z-Wave, 6LoWPAN, Wi-Fi, 2G, 3G, 4G, 5G, LTE, near field communication, radio frequency identification, SigFox, LoRaWAN, Ingenu, Weightless-N, Weightless-P, Weightless-W, ANT, ANT+, DigiMesh, MiWi, EnOcean, Dash7, and WirelessHART. The client controller 32b controls each of the associated client autonomous vehicles 10b, while the master controller 32a makes the course decisions, speed, and the like for the herding system 110.

The master communication unit 40a may also include an embedded cellular telephone to enable communication from a user (not shown) at a remote location to the master autonomous vehicle 10a and the herding system 110. The user may provide commands to the herding system about where to move the group of animals 100 or to return the group of animals to a home base of operation, such as a barn, cattle stall, livestock shed, or cot.

The herding system 110 may also include a herding apparatus 120 in the form of physical restraints 121 extending around the outer perimeter P of the formation of the autonomous vehicles 10 to form a fence. A ranch hand or operator may set the master autonomous vehicle 10a and the client autonomous vehicles 10b around the group of animals 100 and attach the herding apparatus 120, after which the system may operate fully in autonomously. In one embodiment, the physical restraint may be a plurality of bars 122 rotatably connected to the master autonomous vehicle 10a and the client autonomous vehicles 10b as illustrated in FIG. 2. In the embodiment further illustrated in FIG. 3, the bars 122 are connected to the associated master or client autonomous vehicles 10a, 10b by a ball joint 124, although any rotatable or flexible connection that permits flexibility and movement due to slight elevation changes, such as one of the autonomous vehicles 10 passing over a rock, may be used.

In another embodiment, illustrated in FIG. 4, the physical restraints 121 may be a plurality of flexible nets or ropes 126 connected to the master autonomous vehicle 10a and the client autonomous vehicles 10b. The flexible nets or ropes 126 may be used to provide flexibility in both the vertical and horizontal directions as the master autonomous vehicle 10a and the client autonomous vehicles 10b are not likely traveling over a flat surface. The flexible nets or ropes 126 may be connected to the associated master or client autonomous vehicles 10a, 10b by any suitable fastener known to those skilled in the art.

In yet another embodiment, illustrated in FIG. 5, the herding apparatus 120 does not include any physical restraints between the master autonomous vehicle 10a and the client autonomous vehicles 10b. Instead, the herding apparatus 120 may include speakers 42, illustrated in FIG. 1 on a generic autonomous vehicle used with the herding system 110, for emitting tones to direct the group of animals 100 installed on the master autonomous vehicle 10a and the client autonomous vehicles 10b. The tones may be the sound of herding animals, natural predators for the group of animals 100, or any other tones that would cause the group of animals 100 to move. The speakers 42 are in electronic communication with the respective master and client controllers 32a, 32b, and are operated at the direction of the master controller 32a. For, example, in order to move the group of animals 100 in a forward direction, the client autonomous vehicles 10b in the rear of the formation may emit tones 150 causing the group of animals 100 to move away from the tones 150 and in a forward direction, such as how sheepdogs herd a group of sheep, described in a paper “Why we programmed a robot to act like a sheepdog,” reprinted from https://theconversation.com/why-we-programmed-a-robot-to-act-like-a-sheepdog-96961 on Jul. 30, 2018 and incorporated herein by reference. The more forward client autonomous vehicles 10b and the master autonomous vehicle 10a may also emit tones 150 to control the movement of the group of animals 100, such as preventing them from moving forward too fast or too far. The emitted tones 150 may be selected from a tones best calculated to move the type of animal or animals in the group of animals 100 by methods known to those skilled in the art.

In an alternate embodiment as illustrated in FIG. 1, in place of speakers 42, or in addition to the speakers 42, each autonomous vehicle 10 may be equipped with lights 43 that may flash in such a manner that causes the group of animals 100 to move.

In embodiments that do not include physical restraints 121, each animal 130 in the group of animals 100, illustrated in FIG. 6, may include an RFID tag 132 embedded in the animal 130 or carried by the animal 130, such as on a collar 134. The herding system 110 may track the animals 130 in the group of animals 100 using the RFID tag 132 by using the master communication unit 40a on the master autonomous vehicle 10a, or, for a larger group of animals 100, using the master and client communication units 40a, 40b on the master and client autonomous vehicles 10a, 10b.

In still yet another embodiment, also illustrated in FIG. 5, the herding system 110 may include a wrangler autonomous vehicle 10c that follows the herding system 110 and, if one animal 130 of the group of animals 100 is detected to have left the formation, may follow the animal 130 or prompt the animal 130 to return to the formation by emitting a tone 150 from a speaker 42 installed on the wrangler autonomous vehicle 10c.

The wrangler autonomous vehicle 10c may include a controller 32c that is in communication through a communication unit 40c with the master controller 32a of the master autonomous vehicle 10a. The wrangler autonomous vehicle 10c may operate like the client autonomous vehicles 10b under the control of the master autonomous vehicle 10a. Alternatively, the wrangler autonomous vehicle 10c may operate independently but in coordination with the master autonomous vehicle 10a, thereby providing the wrangler autonomous vehicle 10c freedom to operate outside the bounds of formation of the herding system 110, but with enough coordination as to pathways, speed, direction, and the like of the herding system 110 to prevent any collisions of the autonomous vehicles 10.

In yet another embodiment, the wrangler autonomous vehicle 10c may operate independently of any master autonomous vehicle 10a as a single vehicle herding system 110.
