Embodiments described herein generally relate to an Automated Farm with Robots Working on Plants. The Automated Farm with Robots Working on Plants heavily automates indoor farming, especially the tasks of cloning, trimming or pruning, harvesting, inspecting, and maintaining cannabis and hemp plants. This is accomplished using robots with specialized attachments, conveyors, and dedicated rooms that are specifically arranged and controlled to facilitate various automated tasks and/or stages of development of the plants.
As a result of years of research and development, consumers have become increasingly knowledgeable about the side effects of medications and food manufacturing processes. Consumers are therefore demanding medications, food, and other consumables that are more healthy and natural. Specifically regarding medications, currently cannabis and hemp is becoming more and more popular, which is resulting in growth and expansion of the cannabis and hemp industry. CBD oil may be used to treat or cure various ailments without the harsh side effects resulting from many other treatments. Cannabis and hemp farms all over the world are incorporating new technology and innovations to advance the production process to new levels. However, there is still a large opportunity for improvements to be made.
One of the major challenges cannabis and hemp farmers face is how delicate and unusual the cannabis or hemp plant is. Cannabis and hemp plants differ from most other plants in that they are harder to clone, trim, harvest, and maintain. To get the most out of cannabis and hemp plants, they have to be tended daily. In this respect cannabis and hemp plants are not like a field crop. They are more similar to a garden crop but even more demanding in that they must be tended frequently. Since these plants have such high upkeep, cannabis and hemp production is manual, redundant, and tedious work. At the same time, the hemp industry is rapidly growing, so that hemp farms are struggling to keep up with demand and paying excessive labor costs in order to maintain their crop. Accordingly, there is an unmet need for an Automated Farm with Robots Working on Plants that is capable of meeting production demands, while meeting the specific requirements of cannabis or hemp plant husbandry.
Embodiments described herein relate to an Automated Farm with Robots Working on Plants. The Automated Farm with Robots Working on Plants comprises an automated indoor farm that includes specialized plant tending robots able to perform many of the cloning, trimming or pruning, harvesting, inspecting, maintaining, curing, and shipping tasks. Many of these tasks are accomplished using specialized tools attached to robots manufactured by FANUC America Corporation™, located at 3900 West Hamlin Rd., Rochester Hills, Mich. 48309. Additional engineered mechanisms contribute to the overall process. The specialized tools allow the robots to search the plants and find what they need in order to harvest, clone, trim, inspect, and maintain the plants. Conveyors and other devices are used to allow the entire farm to fully function under the supervision of a few people, rather than 30 or 40 employees normally required to operate a similarly sized farm.
The Automated Farm with Robots Working on Plants provides growing rooms for cannabis and hemp plants that are environmentally controlled, and specifically temperature, humidity, light, and air quality controlled for the needs of the plants at their various stages of cloning and development. Air exhausted from the growing rooms is filtered and treated in order to minimize any impact on the community in which the farm is located. The Automated Farm with Robots Working on Plants is physically arranged so that the cloning, inspecting, maintaining, trimming or pruning, and harvesting activities may be accomplished with minimal manual intervention. Each such activity is appointed a room and an arrangement of robots and other equipment that is efficiently dedicated to that task.
The cannabis and hemp plants at various stages of development are moved as necessary between and within rooms using power roller conveyors, chain transfers, lift mechanisms, gravity skate wheel conveyors, transports, motorized racks, and specialized pots and trays. The specialized pots and trays may be provided with trellises and/or training arms in order support the top-heavy cannabis or hemp plants, along with rotation holders that allow compatible rotating devices to rotate the cannabis or hemp plants in the tray. Robots using specialized tools receive the cannabis or hemp plants in their specialized trays and pots from the transport mechanisms, and are used to clone, trim or prune, harvest, inspect, and/or maintain the cannabis or hemp plants. Scrap material collection systems collect and dispose of scrap material. Other specialized robots and equipment perform transplanting and shipping tasks.
Small cubes of soil or Rockwool are used as a growing medium. They are handled and prepared by robots and other equipment, so that the robots having specialized tools for cloning, trimming, harvesting, and etcetera, are able to insert the clone plants into the prepared cubes of soil or Rockwool. Even the nursery that receives the newly cloned plants is heavily automated, with similar temperature, humidity, light, and air quality controls, and similar automated transport mechanisms, as the grow rooms.
A farm control and data management system based on a control system network is used to coordinate the functions of the Automated Farm with Robots Working on Plants. Generally, the control system network operates all aspects of the farm automation including cloning, trimming or pruning, harvesting, inspecting, and maintaining the plants. The control system network is connected to cloning cells, planting cells, pruning or trimming cells, harvesting cells, and etcetera, by way of Industrial Programmable Logic Controllers, which it uses to control the robots, transport mechanisms, and environmental controls. The control system network may also log a large amount of data including atmospheric conditions and pictures of the plants.
According to one embodiment of the invention, an automated farm includes a cloning room and an environmentally controlled nursery with a storage and retrieval system, child storage racks, and child conveyor trays. The automated farm further includes environmentally controlled grow rooms, environmentally controlled lighted and unlighted flower rooms, a trimming or pruning room, and a harvest room. The automated farm includes specialized parent plant pots and tray and trellis systems. Plant tending robots are configured to perform cloning, trimming, pruning, harvesting, and maintaining of plants. The automated farm includes a transport mechanism including at least one conveyor configured to transport the child conveyor trays, the parent plant pots, and the tray and trellis systems between the cloning room, the nursery, the grow rooms, the lighted and unlighted flower rooms, the trimming or pruning room, and/or the harvest room. The automated farm also includes a farm control and data management system.
According to another embodiment of the invention, a farm control and data management system is used with an automated farm having a cloning room, an environmentally controlled nursery with a storage and retrieval system, child storage racks, and child conveyor trays. The automated farm also has environmentally controlled grow rooms, environmentally controlled lighted and unlighted flower rooms, a trimming or pruning room, and a harvest room. The automated farm has parent plant pots and tray and trellis systems. The automated farm has plant tending robots configured to perform cloning, trimming or pruning, harvesting, and maintaining of plants. The automated farm further has a transport mechanism including at least one conveyor configured to transport the child conveyor trays, the parent plant pots, and the tray and trellis systems between the cloning room, the nursery, the grow room, the lighted flower room, the unlighted flower room, the trimming or pruning room, and/or the harvest room. The farm control and data management system includes a control system network configured to control and operate an environmental control system, the storage and retrieval system, the plant tending robots, and the transport mechanism using Programmable Logic Controllers.
According to another embodiment of the invention, a method for automated farming includes several steps. The first step is providing a cloning room. The second step is providing an environmentally controlled nursery with a storage and retrieval system, child storage racks, and child conveyor trays. The third step is providing environmentally controlled grow rooms, environmentally controlled lighted and unlighted flower rooms. The fourth step is providing a trimming or pruning room and a harvest room. The fifth step is providing parent plant pots and tray and trellis systems. The sixth step is configuring plant tending robots to perform cloning, trimming or pruning, harvesting, and maintaining of plants. The seventh step is configuring a transport mechanism including at least one conveyor to transport the child conveyor trays, the parent plant pots, and the tray and trellis systems between the cloning room, the nursery, the grow rooms, the lighted and unlighted flower rooms, the trimming or pruning room, and/or the harvest room. The eighth step is providing a farm control and data management system.
The Automated Farm with Robots Working on Plants is able to improve plant productivity, minimize labor, and better meet the specific requirements of cannabis and hemp plant husbandry.
The above-mentioned and other features of embodiments of the Automated Farm with Robots Working on Plants, and the manner of their working, will become more apparent and will be better understood by reference to the following description of embodiments of the Automated Farm with Robots Working on Plants taken in conjunction with the accompanying drawings, wherein:
Corresponding reference numbers indicate corresponding parts throughout the several views. The exemplifications set out herein illustrate embodiments of the Automated Farm with Robots Working on Plants, and such exemplifications are not to be construed as limiting the scope of the claims in any manner.

In the flower room with lights 46, there is a CO2 nozzle 24 that enriches and/or fertilizes the cannabis or hemp plants by saturating the flower room with lights 46 with CO2. There is also a spray nozzle 26, which has a dual effect of cooling the flower room with lights 46 and increasing the humidity thereof. Grow lights 28 are arranged in a grid above the plants in the flower room with lights 46. The grow lights 28 are arranged on an automated light rack 30, which is provided with four automated light rack posts 32 located in the corners of the flower room with lights 46. The four automated light rack posts 32 are each equipped with an integrated screw jack 34 that adjusts the automated light rack 30 up and down. In this way, the grow lights 28 may be adjusted in height, in order to avoid burning and damaging the cannabis or hemp plants due to the grow lights 28 being too close to the plants. Additionally, when the grow lights 28 are turned on, they may be turned all the way up and then lowered after several minutes. This more closely replicates the sun when it comes up in the morning. As a result, the plants wake up faster and consume nutrients better which produces more growth.
Each of the grow rooms 46 and 48 is provided with a grow room exhaust fan 22 that exhausts air from the grow rooms 46 and 48 to the attic. Replacement air is thereby pulled into the grow rooms 46 and 48 by way of the room air filters 44 located between the grow rooms 46 and 48 and the preconditioned air hallway 50. Air from the grow rooms 46 and 48 has a pungent odor that needs to be treated prior to exhausting to the outside. The air is therefore filtered by an activated charcoal filter 16 at the intake of an exhaust blower 14, before being exhausted through an exhaust stack 12. In the attic there may be one or more o-zone generators 18, as well as one or more attic circulation fans 20.

Next, there are provided, for non-limiting example, five vegetation grow rooms 110 that are similar to flower rooms 112 and 114 except some of the flower rooms have lights, as will be explained herein. The vegetation grow rooms 110 may be located adjacent to the clone and parent room 102, harvest room 104, and/or trim and pruning room 106, although it is contemplated that the vegetation grow rooms 110 may be otherwise located. Each vegetation grow room 110 has trays with, for non-limiting example, sixty plants per tray, although it is contemplated that more or less plants per tray may be used. All of the rest of the grow rooms throughout the farm may have, for non-limiting example, ten plants per tray, although it is contemplated that more or less plants per tray may be used. There are a total of, for non-limiting example, twenty flower rooms 112 and 114. Ten of them are flower rooms with lights 112, and ten of them are flower rooms without lights 114. The flower rooms without lights 114 are directly across from the flower rooms with lights 112. A flowering operation gives the plants twelve hours of light per day. In order to facilitate this, the plants travel back and forth between the flower rooms with lights 112 and the flower rooms without lights 114 every twelve hours. Air intakes 116 are located above overhead doors at the main entrances at each end of the building. The air intakes 116 as described earlier prepare the air that enters the hallway with heat, humidity, and etcetera.
As an example, when a parent plant pot 160 is being transferred into position, it will self-locate along the parent power roller conveyor 150. The chain transfer 152 will lift up, turn, and move the parent plant pot 160 onto the gravity skate wheel conveyor 154. Then the chain transfer 152 will lower, placing the parent plant pot 160 onto the gravity skate wheel conveyor 154. The lift mechanism 158 lifts the gravity skate wheel conveyor 154 under the parent plant pot 160. Gravity rolls the parent plant pot 160 downhill against the first palette stop 156, and then the palette stop 156 lowers so the parent plant pot 160 can move on to the next palette stop 156, and so on. Proximity sensors read the position of the parent plant pot 160, the chain transfer 152 moves up and down, and the palette stops 156 raise and lower as required to place the parent plant pot 160 where desired.

A storage and retrieval system 210 is provided with a track 208, so that the motorized child storage racks 202 are able to traverse the track 208 using powered wheels or powered actuators 214 to their intended destination. Each child storage rack 202 is further provided with at least one movable shelf 212 that raises up-and-down, as well as features that convey the child conveyor trays 200. The at least one movable shelf 212 receives child plants from the gravity conveyor 204 and transfers them to the child storage rack 202 and back as required. The powered wheels 214 and drivetrain of the child storage rack 202 of the storage and retrieval system 210 are used to keep it in position for loading and unloading. The child conveyor control system (not shown) is an industrial Programmable Logic Controller (PLC). The movable shelf 212 and the powered wheels 214 are powered by servomotors (not shown).

The tray 302 may be designed to give each plant a 20 inch by 20 inch area to live in, for non-limiting example. The tray 302 may therefore be 100 inches long and 40 inches wide. A trellis frame 306 is connected to the tray 302. Trellises are required for growing cannabis or hemp because, as the flowers develop, the top of the plant gets very heavy and tends to fall over and break. Traditional trellises are hard to use with automation. The typical trellis in use today is made from a unitized grid of string or plastic net. This makes traditional trellises very difficult for robots to work around, especially during harvest. The trellis frame 306 of the present disclosure supports, for non-limiting example, four trellis combs 308, although it is contemplated that more or less trellis combs 308 may be used. Each of the trellis combs 308 has a trellis comb spine 310 and multiple trellis comb ribs 312 attached to the trellis comb spine 310 that are equally spaced apart to create a grid of the desired size. The trellis comb spine 310 and the trellis combs 308 are positioned approximately perpendicular to each other to form a grid. This design allows automated devices to pull the trellis combs 308 out horizontally, thereby releasing the plants for harvest.

The grip-cut tool holding robot 360 generally maintains a position perpendicular and centered to the backlight tablet tool 350 held by the backlight tablet tool holding robot 358. The backlight tablet tool holding robot 358 systematically moves the backlight tablet tool 350 through the plant while the camera of the grip-cut tool holding robot 360 looks for an ideal cloning, trimming or pruning, harvesting, and/or maintaining situation. When the ideal cloning, trimming or pruning, harvesting, and/or maintaining situation presents itself to the vision system, the backlight tablet tool holding robot 358 stops and the grip-cut tool holding robot 360 moves in a perpendicular motion to the backlight tablet tool 350, towards the plant. The grip-cut tool holding robot 360 grips the cannabis or hemp plant 354 and cuts the branch, leaf, or flower to be removed.

To accomplish this, the parent plant pot and training tools assembly includes a parent plant pot 400, which may be square in shape, although the use of other shapes is contemplated. The parent plant pot 400 may be of pot metal construction, for non-limiting example, with a perforated bottom that allows water and nutrients to pass therethrough. However, it is contemplated that the parent plant pot 400 may be constructed from other materials. The parent plant pot 400 also has features that secure four corner posts 404. For non-limiting example, there may be four corner posts 404 that slide into pockets on the pot (not shown). These corner posts 404 provide a foundation for a number of training arms 406. Each training arm 406 is provided with an adjustable clamp 408 that allows the training arm 406 to slide up and down the corner post 404. The adjustable clamp 408 further allows the training arm 406 to rotate around the corner post 404. Common plant tying materials may then be used to tie the parent cannabis or hemp plant to the training arm 406. In at least one embodiment, each training arm 406 may be provided with clips, as depicted in
The backlight tablet tool holding robot 452 and the grip-cut tool holding robot 454 perform operations on the cannabis or hemp plant 458 upon a roller conveyor turn table 456, which receives the cannabis or hemp plant 458 from the parent plant conveyor 450. Specifically, the backlight tablet tool holding robot 452 locates a start to be taken from the parent cannabis or hemp plant 458 by the grip-cut tool holding robot 454. Once the clone has been removed from the parent cannabis or hemp plant 458, the grip-cut tool holding robot 454 takes the clone to a clone preparation tank 502 mounted on a clone planting pedestal 460 that contains a rooting hormone solution 504. The grip-cut tool holding robot 454 dips the clone in the clone preparation tank 502. While the clone is submerged, two blades 506 and 508, one fixed blade 506 that is fixed to the clone preparation tank 502 and a movable blade 508 that is on an actuator 510, work together to rough up the bottom of the stem so the clone has a better interaction with the rooting hormone solution 504. Then the grip-cut tool holding robot 454 moves the clone over onto clone planting pedestal 460. Then the grip-cut tool holding robot 454 places the clone in a Rockwool plug that has been prepared by a Rockwool plug robot 462.
The Rockwool plugs come to the operation in large totes. A tote full of plugs is dumped as needed into a flex feeder 466 by a tote dumper 468. The flex feeder 466 has a backlit bottom that shakes up and down to randomly arrange plugs for the Rockwool plug robot's vision system. The flex feeder 466 presents the Rockwool plugs to the Rockwool plug robot 462. The Rockwool plug robot 462 picks up the plug and rinses it in the three solutions in pH controlled rinse tanks 464. Then the Rockwool plug robot 462 places the Rockwool plug on the clone planting pedestal 460 where the grip-cut tool holding robot 454 inserts the clone into the Rockwool plug. The Rockwool plug robot 462 then puts the planted clone in a child tray 470 located on the child conveyor 472.
A nursery has two separate chambers, a first larger nursery chamber 476 for newly planted clones, and a second nursery chamber 478 for more developed clone child cannabis or hemp plants. Each of the nursery chambers is provided with temperature and humidity controls 474. The second nursery chamber 478 has less humidity than the first nursery chamber 476, and prepares the more developed clone child cannabis or hemp plants for the grow rooms. Plant racks 480 in the first and second nursery chambers 476 and 478 provide a location for the cloned cannabis or hemp plants to grow, and are provided four levels each for this purpose. The bottom of each level of the plant rack 480 has gravity skate wheels for the child tray 470 to ride on. A lifting device (not shown) at the back of each plant rack 480 lifts one end of the bottom of each level up causing the gravity skate wheels to shuttle the child trays 470 out as needed.
A transporter track 482 along the front of the plant racks 480 is provided with a transporter 484 that moves back-and-forth across the front of the plant racks 480. The transporter 484 is provided with a shelf (not shown) that moves up and down to the four levels of the plant racks 480. In order to put a child tray 470 of newly planted clones into a plant rack 480, the transporter 484 positions itself in front of that plant rack 480. The shelf of the transporter 484 then raises to the correct level and transfers the child tray 470 to the plant rack 480 by pushing the child tray 470 into the plant rack 480. The shelf of the transporter 484 has the ability to move a child tray 470 in and out of the plant rack 480 as well as on and off of the child conveyor 472.
When the cloned cannabis or hemp plants are fully mature, they may be sold or moved to grow rooms either in trays of small Rockwool plugs or in trays of Rockwool plugs that have been transplanted into their larger Rockwool cube. The system for preparing Rockwool cubes includes a conveyor 488 that conveys pallets full of Rockwool cubes, which are 6″×6″×6″ in size. A gantry frame 490 has a gantry head with integrated shelf 494, and is used to move a row of cubes. A top layer pusher and scissor lift 492 separates a layer of Rockwool cubes and moves them to preparation tanks 496. A transplant robot 486 then moves completed clones to the trays or to Rockwool cubes. Finally the completed clones are staged in dunnage 498 and prepared for delivery using a conveyor 500.

Room is provided between the four spray nozzles 564 for a door or section of a conveyor to drop into, whereupon photo eyes (not shown) of the control system 562 activate the portable spray station 550. In this way, the portable spray station 550 is used to spray material on cannabis or hemp plants for their well-being. It can also be used to clean the cannabis or hemp plants. The portable spray station 550 can be positioned at many points in the farm. As noted previously, the portable spray station 550 is able to locate under a conveyor section where the plants will pass. In this way, portable spray station 550 is able to spray the plants as they pass down the conveyors, or as they cross a hallway.

Similarly, the control system network 700 may further be connected to room controllers 728 having programmable logic controllers 730 for the robots and other equipment, robot vision systems 734, and human machine interfaces 732. Multiple similar arrangements may be provided for rooms having conveyors, fans, watering stations, testing stations, spray stations, and/or inspection cameras. The control system network 700 may further be connected to a hallway conveyor control 736 having a programmable logic controller 738 and a human machine interface 740. A main programmable logic controller 726 may be provided to coordinate the functions of the Automated Farm with Robots Working on Plants, as well as to control miscellaneous functions such as lighting control, CO2 control, HVAC control, and/or humidity control. Generally, the control system network 700 operates all aspects of the farm automation. The control system network 700 may also log a large amount of data including atmospheric conditions and pictures of the plants.

Additionally, a plant manipulator 766 is provided. The plant manipulator's positioning is controlled by two servo-motors (not shown). The plant manipulator 766 reaches into the plant using a manipulator attachment 768 as the parent pot turntable 754 moves, thereby pushing the plant's branches against the manipulator attachment 768. This action opens an area for the backlight tablet tool holding robot 758 and the grip-cut tool holding robot 762 to work on the cannabis or hemp plant 750, thereby further facilitating the process of cloning, trimming or pruning, harvesting, inspecting, and maintaining.
