Definitions
- the present disclosure relates to an apparatus and method for autonomous Controlled Environment Agriculture (CEA), including without limitation for the purpose of cultivation of organic produce and other organic or natural products and in vertical farming applications.
- CEA Controlled Environment Agriculture
- the disclosed apparatus and method can also be utilized for more general application in the fields of agriculture, material handling, and warehousing, including without limitation, modular pallet warehousing.
- Controlled Environment Agriculture is an evolving technique for the precision cultivation of organic produce through the artificial control of influential environmental factors.
- An appeal to facilitate the desirable outcomes of growth, this type agriculture may require the regulation of parameters pertaining to atmospheric, nutritional, spatial, or electromagnetic qualities. In doing so, a precise understanding of an organic system’s overall production with respect to time is much more attainable.
- Systems like these can vary in size, ranging from a household appliance, to a standard freight shipping container, to a 10,000 square-meter warehouse, to a multi-hectare greenhouse.
- CEA systems are typically equipped with a general selection of actuators and sensors to monitor and control the environment.
- CEA offers the appeal of being resistant to growth-inhibiting factors, such as droughts, famine, floods, or winters. Because of this resiliency, consistent, year-round production is possible for a wide range of geographic scenarios, including urban, desert, artic, and deep space regions.
- CEA systems running at a commercial capacity require a wide range of manual tasks to be performed by farmhands on a daily basis. These responsibilities may include the harvesting, cleaning, creation, inspection, and moving of product, the maintenance, sensing, control, and logistical planning of the environment, and the analysis of any data that may be subsequently collected.
- responsibilities may include the harvesting, cleaning, creation, inspection, and moving of product, the maintenance, sensing, control, and logistical planning of the environment, and the analysis of any data that may be subsequently collected.
- CEA systems Despite being computer-controlled and with sensory feedback, CEA systems have many logistical points of failure that require technical skills from the farmhands in order to maintain. Appropriately so, commercial CEA systems are sometimes referred to as“plant factories” for their resemblances to manufacturing environments.

- the inventory management is FIFO because the system includes a pair of coordinated carriage mounted manipulators 82 wherein the first manipulator 82 manipulator which can then unload a the tray assembly 40 from the lane that had been in the lane the longest.
- FIG. 16-26 The embodiments of Figures 16-26 are capable of LIFO without the use of a gravity conveyor because a single manipulator 182 is capable of pulling the last loaded tray assembly 140 off of a lane 200, and in doing so indexes each tray assembly 140 one step rearwards towards the manipulator 182.
- a single manipulator 182 mounted on a carriage 180 is used which provides the same amount of productivity as the above-described embodiments utilizing two manipulators 82 while removing the need to coordinate movements of two manipulators 82. This allows for more consistent grasps by the manipulator 182 and requires fewer movements to access a frame assembly 141.
- a friction based staging area may also be provided.
- frame assemblies 141 are slidable forwardly and rearwardly in long track assemblies 118 along a forward and rearward direction of travel within a plurality of horizontal lanes 200 arranged in a plurality of vertical columns 202 in rack 111.
- each frame assembly 141 includes stiffeners 142 and low-friction bearings 146 rollable on tracks 119 of a track assembly 118 to move the frame assembly 141 in the forward and rearward direction of travel X.
- frame assembly 141 is configured to move on a track assembly 118 that is secured to rack 111.
- Frame assembly 141 bears directly onto a friction surface 220 incorporated into the track assembly 118.
- the friction surface 220 exerts countering forces overcome linear motion that is normally facilitated by the low-friction bearing 146 on the track 119.
- the static forces produced by the friction surface facilitate the precise positioning of the frame assembly 141 when being placed and retrieved by a carriage-mounted manipulator 182.
- a guard 222 prevent linear displacement of the frame assemblies 141.
- tracks 119 may include wheels 204 on which the frame assemblies 141 slide upon.
- Each frame assembly 141 in each horizontal lane 200 is configured to couple to an adjacent frame assembly 141.
- Each frame assembly 141 has at least one coupler 206, 208 on the forward and rearward ends 210, 212 of the tray assembly.
- the at least one coupler 206 on the forward end 210 are first and second forward couplers 206
- the at least one coupler 208 on the rearward end 112 are first and second rearward couplers 208.
- first and second forward couplers 206 and the first and second rearward couplers 208 are a pair of spaced hook shaped components 214 each having a first proximal portion 216 substantially perpendicular to the respective end 210, 212 of the frame assembly 141 and substantially parallel to the direction of travel X, and a distal portion 218 substantially perpendicular to the forward and rearward direction of travel X and parallel to the corresponding end 212, 214 of the frame assembly 141.
- Each pair of the first and second forward couplers 206 on a frame assembly 141 is configured to couple with the first and second rearward couplers 208 of an adjacent frame assembly 141 in the forward direction of travel.
- each first and second forward couplers 206 extends in the opposite direction to the second distal portions 218 of the first and second rearward couplers 208 of an adjacent tray assembly such that each frame assembly 141 is rotationally symmetrical about an axis normal to the width and length frame assembly plane.
- This rotational symmetry allows for bidirectional operation of the manipulator 182 and allows for frame assemblies 141 to be placed anywhere without the need to rotate the frame assembly 141.
- Other forms of couplers and arrangements are acceptable.
- having multiple coupling features having a positive engagement latch or drop pin, as commonly found in gates and train cars; dropping a tray assembly onto a hitch; powerful magnets; engagement of a cam or key feature; fastening and unfastening with screws; no coupler, instead a gravity flow rack and a sufficiently powerful manipulator to overcome increased indexing loads.
- the manipulator would then be configured to correspond to the coupler to allow for coupling and decoupling.
- the couplers 206, 208 may be integral with the frame assembly 141 of each tray assembly 140 material and be made from a corrosion-resistant cast low carbon steel, aluminum, or stainless steel. They may also be made from aluminum extrusions, formed heavy gauge steel, aluminum, or stainless sheets, formed stainless wire, or subtractively or additively manufactured metal. The couplers 206, 208 may also be attached to stiffeners 142 of the frame assembly 141. [0060] The forward and rearward couplers 206, 208 are the features that the manipulator 182 uses to couple, push, and pull the frame assemblies 141.
- the carriage-mounted manipulator 182 positions itself spatially to a plus or minus tolerance from nominal, it is best for the first and second forward and rearward couplers 206, 208 to be oversized in accordance with tolerances expected from the carriage-mounted manipulator 182. This ensures that a manipulator 182 positioned“slightly off” can still couple to a coupler 206, 208 without the need for sophisticated actuation or sensing. Because the coupler 206, 208 is oversized in this way, there exists a small (about 0.25”) amount of linear play from one coupler 206, 208 engaged to another.
- a first frame assembly 141a being added to a lane 200 is coupled to second frame assembly 141b on the lane 200 as follows:
- the carriage-mounted manipulator 182 engages to the first frame assembly 141a and positions the first and second forward couplers 206 on the first frame assembly 141a above the first and second rearward couplers 208 of the second frame assembly 141b.
- Manipulator 182 lowers the first frame assembly 141a (for example, a few inches) such that the first and second forward couplers 206 on the first frame assembly 141a slide into the first and second rearward couplers 208 of the second frame assembly 141b.
- the first frame assembly 141a is now coupled to the second frame assembly 141b in the direction of travel X of the lane 200 with the couplers 206 and 208 being coplananr a configured to transmit force in the direction of travel X.
- the manipulator 182 may push the first frame assembly 141a towards the second frame assembly 141b and index the series of interconnected frame assemblies 141a, 141b one index.
- Manipulator 182 disengages from the first frame assembly 141a.
- a first frame assembly 141a is decoupled from a second frame assembly 141b on the lane as follows: [0068] 1.
- Manipulator 182 engages to the first frame assembly 141a.
- Manipulator 182 pulls the first frame assembly 141a, subsequent frame assemblies 141 are pulled towards the manipulator 182 one index. The first frame assembly 141a is now secured by the manipulator 182.
- Manipulator 182 raises the first frame assembly 141a (for example, a few inches) such that the first and second forward couplers 206 of the first frame assembly 141a slide from the first and second rearward couplers 208 of the second frame assembly 141b.
- an engagement thumb 224 having projections 230 for connecting to a coupler 208 on a frame assembly 141 fixedly connects to a parallel-driven belts 226.
- Pulleys 228 driven clockwise or anticlockwise, are used to provide transmission to the belts 226, which power and guide linear motion of the engagement thumb 224 in the direction of travel X as dictated by the track assembly 118.
- Bi-directional motion of the engagement thumb 224 is possible, allowing for manipulation paradigms to both available sides of the manipulator 182.
- the carriage-mounted manipulator 182 is fixed near the frame assembly 141 with the engagement thumb 224 positioned below the coupler 208 to be manipulated.
- the pulleys 228 provide power to the belts 226, which motions vertical movement of the engagement thumb 224 to slide into the coupler 206 and engage.
- the pulleys 228 continue to drive as the motion of the engagement thumb 224 transitions from vertical movement to horizontal, pulling the first-out frame assembly 141b and all subsequently coupled frame assemblies 141 along the same track assembly 118 a distance of one index.
- the manipulator 182 moves vertically to disengage the coupler 208 of the secured frame assembly 141 from the newly positioned first-out frame assembly 141a, if present.
- the carriage-mounted manipulator 182 is positioned near the track assembly 118 of interest. As is shown in Figure 25, the manipulator 182 is oriented vertically to engage the coupler 208 of the secured frame assembly 141a to the coupler 206 of the first- in frame assembly 141b within a track assembly 118.
- the engagement thumb 224 in contact to the coupler 208 of the secured frame assembly 141a in the direction of the first-in frame assembly 141b, is powered through the input of the pulley 228 and belt 226 drive system. Compressive force is exerted from the engagement thumb 224 and through the secured frame assembly 141a, causing motion of the secured frame assembly towards the rack 111.
- a guide 232 is used to center the frame assembly 141b during ingress, and guards 222 are used to center the frame assembly 141b along the length of the track assembly 118. Subsequent frame assemblies 141 within the track assembly 118, if present, move one full index. The manipulator 182 disengages its engagement thumb 224 from the newly-positioned first-out frame assembly 141, and the motion is complete.
- the embodiment of Figures 16-24 may also use identifying tags 147 such as an RFID chip or optical feature allowing for tracking from an inventory management system
- a lane 200 containing frame assemblies 141 may be completely emptied by a single manipulator 182, easing manual functions around cleaning and inspecting farm equipment. It is to be understood that the disclosed embodiments are not limited to the farming industry but may be utilized in other autonomous material handling industries such as food and fulfillment operations.
