The net is manipulated to corral or concentrate the fish into a smaller volume. Transponders installed at strategic locations throughout the cage facilitate navigation of the rovers.
Description
Automated Aquaculture Harvesting System
CROSS-REFERENCE TO RELATED APPLICATIONS:
[0001] This application claims priority from United States Provisional Application No. 62/118,175, filed on February 19, 2015. The entire contents of this earlier filed application are hereby incorporated in their entirety.
FIELD:
[0002] Certain embodiments generally relate to robotics, and more specifically, relate to the use of robotic systems in the harvesting of fish from an aquaculture cage.
BACKGROUND:
[0003] Harvesting fish from an aquaculture cage, particularly if it is submerged, or in inclement weather, is a laborious, costly and sometimes dangerous process. Conventional harvesting techniques call for the manipulation of large nets within a cage, thereby corralling and
concentrating fish to a predetermined location within the cage. Once sufficiently condensed, fish are removed manually with nets or
automatically using a combination of pumps and motors. This lengthy procedure results in extended periods of crowding and inducing stress on the remaining unharvested fish, resulting in loss of appetite, decreased growth rate and greater vulnerability to infection. These conventional harvesting techniques can also have an adverse affect on the quality of the harvested fish, ultimately reducing the profitability of the farm.

[0004] For proper understanding of the invention, reference should be made to the accompanying drawings, wherein:
[0005] Fig. 1 illustrates a profile elevation view of an automated harvester, according to one embodiment;
[0006] Fig. 2 illustrates a front elevation view of an automated harvester, according to an embodiment;
[0007] Fig 3. illustrates a plan view of a circular aquaculture cage, according to an embodiment; and
[0008] Fig 4. illustrates an elevation view of an automated harvester with an attached harvest pipe, according to an embodiment.
DETAILED DESCRIPTION:
[0009] It will be readily understood that the components of the invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of certain embodiments of an automated harvesting system and method, as represented in the attached figures, is not intended to limit the scope of the invention, but is merely representative of selected embodiments of the invention.
[0010] The features, structures, or characteristics of the invention described throughout this specification may be combined in any suitable manner in one or more embodiments. For example, the usage of the phrases "certain embodiments," "some embodiments," or other similar language, throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. Thus, appearances of the phrases "in certain embodiments," "in some embodiments," "in other embodiments," or other similar language, throughout this specification do not necessarily all refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0011] Additionally, if desired, the different configurations and functions discussed below may be performed in a different order and/or concurrently with each other. Furthermore, if desired, one or more of the described configurations or functions may be optional or may be combined. As such, the following description should be considered as merely illustrative of the principles, and embodiments of this invention, and not in limitation thereof.
[0012] Aquaculture cages can operate in two configurations: either floating at the surface, or submerged below the surface. Harvesting from traditional surface cages affords easy access to the cage where operators can make use of a service vessel using winches, booms, and seine nets to assist in the harvesting of the fish. However, these cages are generally challenging to operate in exposed open-ocean waters. Even under ideal conditions, open- ocean surface harvesting exposes both farm equipment and fish to the high energy environment of the wave zone, risking potential damage and loss; in more inclement weather, harvest operations may not be possible at all, leading to costly disruptions in the product supply chain.
[0013] Submersible aquaculture cages provide security and survivability in the open ocean, but existing submersible cage technologies are highly inefficient to operate. As these cages must be entirely enclosed, it is far more difficult to manipulate or manage the fish inside the cage. Small access panels and enclosed cage shapes together reduce an operators' ability to apply mechanical advantage when herding or harvesting the fish. Placing divers inside submerged cages, particularly in high sea states or in strong currents, poses an even greater risk as divers could become trapped in the cage.
[0014] There is, therefore, a need to automate harvesting of submerged and surface pens in almost all sea states, without using divers.
[0015] According to certain embodiments of the invention, guided by sensors, two autonomous robotic rovers will deploy a large seine net,
drawing it across an aquaculture cage to pre-defined points along the cage rim, then back towards the base unit to corral or crowd a desired volume of the fish. The robotic rovers may move across the net material by physically gripping and holding onto the mesh. In an embodiment, an array of sensors and closed-loop feedback control will enable the system to unfurl a net and pull it uniformly to any point within the cage. An integrated winch allows the net to be retrieved after harvesting is complete.
[0016] Fig. 1 illustrates an elevation view of one embodiment of the automated harvesting system. As illustrated in the example of Fig. 1, two automated robotic rovers 105, one at the top and one at the bottom of the leading edge of a seine net 106, navigate across an aquaculture cage and draw out the net to any number of locations. To facilitate dead reckoning navigation, sensors 104 within the body of the rover 105 may detect sensors or transponders embedded within the cage ceiling. In another embodiment, sensors or transponders may be embedded within the cage floor 108.
Treaded wheels on the rover 105, which may grip the cage ceiling 107 and/or cage floor 108, provide traction and allow the rovers to move about the cage freely. In one embodiment, the treads, or mechanism by which the cage is gripped, may be extended to grip the mesh and retracted to release the mesh. A drivetrain within the rover body 104 supplies the power required to turn the wheels.
[0017] The automated robotic rovers 105 may be connected on either end of a vertical spar 103 attached to the leading edge of a net 106. In one example, the spar may be made of high-density polyethylene (HDPE).
However, other materials may be used according to other embodiments. The height of the vertical spar 103 may be roughly equal to the height of the cage. However, under different stresses the shape of the cage may change. The spar 103 may compensate by dynamically changing its height
(telescoping) in order to maintain a vertical orientation within the pen and
keep the automated robotic rovers in contact with the ceiling and floor mesh material. In one embodiment, the spar may accomplish this through integrated springs. In another embodiment, the spar may change its height through the use of hydrostatic pressure.
[0018] The base unit 100 may be comprised of a protective casing enclosing the net spool 101 with an integrated winch 102. This base unit 100 may be placed vertically inside the cage along the wall. The height of the net 106 may be equal to the depth of the net pen (i.e., aquaculture cage) and its width may be slightly greater than the diameter of the net pen (i.e., aquaculture cage), allowing the automated harvesting system to bisect the cage without placing any stress on the net.
[0019] In one embodiment, sensors may be installed on the vertical spar 103 to help detect and react to changes in the pitch, roll, and yaw of the spar facilitating closed loop feedback control.
[0020] In yet another embodiment, encoders which track angular
movement, may be installed on the axles of the robotic rovers 104
facilitating closed loop feedback control.
[0021] Fig. 2 illustrates a front elevation view of one embodiment of the automated harvester. As illustrated in the example of Fig. 2, two circular wheels 200 are connected to each other through a fixed axle 203. The drivetrain may be enclosed within the body of the robotic rover 203 along within navigational sensors. A variable-length spar 204 will ensure the wheels 202 are kept in contact with both the cage ceiling 200 and floor 201. In another embodiment, the rovers may include a single wheel and axle connected to the rover body through a hub. In yet another embodiment, the robotic rovers wheels' 202 grip and navigate throughout the cage through the use of a continuous track system.
[0022] Fig. 3 illustrates a plan view of one embodiment of the automated harvester 300 and the navigational sensors or transponders 302 installed on a
circular aquaculture cage 301. As illustrated in the example of Fig. 3, the transponders or navigational sensors 302 may be aligned in a grid formation and detected by sensors installed within the robotic rovers body 105 facilitating dead reckoning navigation. In another embodiment, the sensors 302 may be installed around the perimeter of the cage to reduce signal noise and interference.
[0023] Fig. 4 illustrates the automated harvesting system installed on a submerged aquaculture cage 400, according to one embodiment. As illustrated in the example of Fig. 4, the robotic rovers 401 navigate across the cage drawing the net 402 from its protective enclosure 403. An integrated harvesting tub 404 allows fish to be pumped to the surface from a harvest vessel 405.
[0024] In another embodiment, the automated harvesting system may be installed on a surface pen without any additional equipment (e.g., integrated harvesting tube 404) requiring fish to be scooped out through nets or some other means.
[0025] One having ordinary skill in the art will readily understand that the invention as discussed above may be practiced with steps in a different order, and/or with hardware elements in configurations which are different than those which are disclosed. Therefore, although the invention has been described based upon these preferred embodiments, it would be apparent to those of skill in the art that certain modifications, variations, and alternative constructions would be apparent, while remaining within the spirit and scope of the invention. In order to determine the metes and bounds of the invention, therefore, reference should be made to the appended claims.
