Description:FIELD OF THE INVENTION

[0001] The present invention relates to an agricultural device for performing farming operations that automatically performs various agricultural tasks such as planting, soil analysis, and weed removal, in view of improving efficiency and precision in farming operations.

BACKGROUND OF THE INVENTION

[0002] Farmers are under increasing pressure to produce higher yields to meet the growing global demand for food, while also ensuring that their practices are sustainable and environmentally responsible. Traditional farming methods often rely on manual labour, which is not only time-consuming but also physically taxing. These manual processes, such as planting, harvesting, weeding, and spraying, are crucial for crop development but often lack precision, leading to inefficiencies. For example, overuse or misapplication of fertilizers, pesticides, and water could damage crops, lead to resource wastage, and contribute to environmental pollution. Furthermore, farmers have to deal with the unpredictability of weather conditions, pest outbreaks, and soil health variations, which require timely and accurate interventions.

[0003] Traditionally, there are several devices on the market that help farmers with tasks like planting, harvesting, and spraying, such as automated planters, harvesters, and drones for crop monitoring. While these tools increase efficiency, they often have some drawbacks. Automated planters and harvesters are typically very expensive, which makes them difficult to afford for smaller farms. Drones, though useful for tasks like monitoring crops and spraying pesticides, have limitations like short battery life, weather sensitivity, and they cannot perform physical tasks such as planting or harvesting. Many of these devices also don’t work well together, leaving farmers with multiple, separate tools that don’t communicate with each other. Additionally, some devices are complicated to use, requiring farmers to have advanced technical knowledge, which is a barrier for those who aren’t familiar with the technology.

[0004] AU2022381713A1 discloses a method for collecting data on a field used for agriculture by combining flying remote and ground level sensing, wherein, in a first step, by means of ground level sensing at reference points on the field used for agriculture, the geographical position of the respective reference point is captured and at least one photographic recording of at least one weed on the field used for agriculture is made for each reference point; in a second step, flying remote sensing parameters are determined on the basis of the data from an image analysis of the photographic recordings of the at least one weed for each reference point; and, in a third step, at least the reference points on the field used for agriculture are photographically captured by means of flying remote sensing, wherein at least some of the flying remote sensing parameters determined in step b) are used for the flying remote sensing.

[0005] RU2642118C1 discloses an agricultural implement contains many row units. Row units contain one or more seeds meters for the receipt, the singulation and the seeds issue into the ground, so that the preferred location of the subsequent seeds is achieved. To transport the seeds from the seed meter into the ground, the seeds feeding systems are provided to reduce its jumping and to facilitate the seed spacings control, that can be based on the tool speed relative to the ground, as it moves across the field. The seeds supply system may control the seeds transportation in the field, so that the seeds can have zero or almost zero relative velocity, so that the seeds will not have or will have the slight movement after the location in the rib.

[0006] Conventionally, many devices exist for performing specific farming operations, such as planting, weeding, and monitoring crop health. However, the cited arts have certain limitations pertaining to high costs, limited functionalities, lack of integration between different tasks, and a need for specialized knowledge for operation. These shortcomings make it difficult for smaller-scale farmers to fully benefit from these technologies, preventing them from optimizing their operations and increasing productivity.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of performing farming operations that is capable of performing various farming operations, including soil sampling, planting, and weed management. The developed device should also improve the farming for a user by means of analysing soil conditions, dispense seeds, and maintain crops with minimal manual intervention, thus ultimately enhancing crop yield and optimizing farming practices.

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0009] An object of the present invention is to develop a device that automatically performs farming operations like seed and saplings plantation in targeted areas, thus providing assistance to a user in a precise manner.

[0010] Another object of the present invention is to develop a device that accurately analyses soil conditions and provides real-time data for optimized fertilizer, irrigation, and crop management, thus reducing the need for manual labour and enhancing farming efficiency

[0011] Another object of the present invention is to develop a device that is performing precise seed dispensing in order to ensure uniform seed placement, optimal depth, and soil coverage based on real-time sensor data and field conditions.

[0023] The present invention relates to an agricultural device for performing farming operations that is capable of performing essential agricultural tasks such as soil analysis, planting, and weed removal, promoting precision farming, thus reducing the need for human labor and improving overall crop management.

[0024] Referring to Figure 1, an isometric view of an agricultural device for performing farming operations is illustrated, comprising a body 101 configured with a plurality of motorized wheels 102, an artificial intelligence-based imaging unit 103 mounted on the body 101, a cuboidal unit 104 installed at a base portion of the body 101, a holographic projection unit 105 mounted on the body 101, a motorized iris lid 106 arranged underneath each section of the chamber 122, a conveyer belt 107 attached beneath the chamber 122, a bar 108 assembled with a plurality of frustum-shaped members 109, attached underneath attachments of the conveyer belt 107, a L-shaped linear pusher plate 110 mounted on the conveyer belt 107, a Whitworth quick return assembly 111 installed in between the conveyer belt 107 attachments and the bar 108, a motorized iris aperture 112 installed at a lower portion of the members 109, an elongated cylindrical unit 113 arranged with the body 101 and equipped with a hopper 114 at a top portion, a motorized slider 115 installed in between the unit and body 101, a motorized iris gate 116 attached underneath the structure 124, a pair of L-shaped links 117 attached with a motorized ball and socket joint 118, installed on lateral sides of the unit, a robotic gripper 119 installed on the body 101, an electronic nozzle 120 is assembled on the body 101, and a vessel 121 configured with the nozzle 120, a multi-sectioned chamber 122 arranged within the body 101, a robotic arm 123 installed on the body 101, and a conical structure 124 installed at a bottom portion of the cylindrical unit 113, and a container 125 installed within the body 101.

[0025] The present device includes a body 101 preferably in portable cuboidal shape encasing various components associated with the device, developed to be positioned on a ground surface where a user desires the farming operations to be performed. The body 101 is made up of any material selected from but not limited to metal or plastic that ensures rigidity of the body 101 for longevity of the device.

[0026] The user access and presses a push button arranged on the body 101 to activate the device. The push button when pressed by the user, opens up an electrical circuit and allows currents to flow for powering an associated microcontroller of the device for operating of all the linked components for performing their respective functions upon actuation. The microcontroller, mentioned herein, is preferably an Arduino microcontroller. The Arduino microcontroller used herein controls the overall functionality of the components linked to it.

[0027] After the activation of the device, the user accesses a user interface which is inbuilt in a computing unit linked with the microcontroller wirelessly by means of a communication module. The user interface enables the user to provide input regarding desired farming operation. The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The Wi-Fi module contains transmitters and receivers that use radio frequency signals to transmit data wirelessly to the microcontroller.

[0028] The wireless module typically includes components such as antennas, amplifiers, and processors to facilitate communication and further connected to networks such as Wi-Fi, Bluetooth, or cellular networks, allowing devices to exchange information over short or long distances of the body 101 for communication of wireless commands to facilitate operations of the device.

[0029] The microcontroller processes the input commands and activates an artificial intelligence-based imaging unit 103 installed over the body 101 to generate a three-dimensional map of the field. The imaging unit 103 includes a camera that captures images of the field to gather comprehensive visual information. The imaging unit 103 is linked with a processor that preprocesses the captured images which involves noise reduction to clean the distortions followed by adjusting brightness, contrast, and color balance to make the images more uniform.

[0030] Then, the feature extraction is done using artificial intelligence protocol to identify and extract key features or patterns from the images to highlight significant elements within the image. Artificial intelligence protocols involve deep learning models that are trained to recognize and classify objects, detect anomalies, or segment images into different regions. At last, the processed images are sent to the microcontroller for generating a three-dimensional map of the field.

[0031] The generated map is displayed on the user interface and the user selects an area where the farming operation is to be performed. Based on the detected position, the microcontroller actuates plurality of motorized wheels 102 configured with the body 101 to maneuver towards the selected area. The motorized wheels 102 operate by integrating an electric motor with a wheels 102 to provide motion. The process begins when the motor receives electrical power from a power source which is converted into mechanical energy by the motor, which generates rotational force. When the motor is activated, the motor's shaft starts to rotate at a pre-fed speed, causing the wheels 102 to spin and position the body 101.

[0032] The base of the body 101 is installed with a cuboidal unit 104, attached with a motorized hinged flap for collecting soil sample from the selected area. Upon positioning of the body 101, the microcontroller actuates the hinge and the flap reached the soil on the surface for collecting the soil. The hinge is re-actuated to move the flap upwards and the soil sample is collected in the cuboidal unit 104. The motorized hinge used herein, is a piece of metal that joins two sides or items together and allows it to be opened or closed by revolving along the longitudinal axis whose operation is governed by a DC motor to move the flap and securing the sample inside the cuboidal unit 104. This ensures controlled and efficient soil collection with minimal manual intervention.

[0033] The cuboidal unit 104 is integrated with a sensing module to determine soil conditions such as texture, bulk density, compaction and nutrients in soil of the selected area. For this, sensing module includes plurality of sensors that includes but not limited to a moisture sensor, a penetrometer, a laser diffraction sensor, a pH sensor, and an ion-selective electrode.

[0034] Moisture sensor works by detecting the soil’s water content using two electrodes that are placed in the soil, and as the moisture level changes, so does the electrical resistance between them. The sensor translates these readings into signal that is sent to the microcontroller that processes the signal and determines moisture level data, helping assess irrigation needs.

[0035] The penetrometer works by inserting a probe into the soil and measuring the resistance encountered during penetration. The force required to penetrate the soil gives an indication of its compaction. The sensor translates these readings into signal that is sent to the microcontroller that processes the signal and helps understand the soil’s porosity and its ability to allow root growth.

[0036] Laser diffraction sensor analyzes soil particles by measuring how a laser beam is scattered as it passes through the soil. Smaller particles scatter light differently than larger particles, and the sensor translates these readings into signal that is sent to the microcontroller that processes the signal to determine particle size distribution. This helps assess soil texture (sand, silt, clay) and its suitability for specific crops.

[0037] The pH sensor works by measuring the concentration of hydrogen ions (H⁺) in the soil. It uses a glass electrode to detect the ion concentration and generate an electrical potential that is sent to the microcontroller that processes the signal and converted into a pH value. This value indicates whether the soil is acidic, neutral, or alkaline, affecting nutrient availability and plant growth.

[0038] Ion-selective electrode sensor measures the concentration of specific ions, such as potassium or nitrate, in the soil. The sensor works by using an electrode that selectively interacts with a particular ion, producing an electrical potential that is sent to the microcontroller that processes the signal proportional to the ion concentration. This data helps evaluate nutrient levels, enabling farmers to adjust fertilization practices. Based on the detected soil conditions, the microcontroller compares the conditions with a pre-fed data and identify the requirement of fertilizers, irrigation schedules and crop management techniques.

[0039] To fulfill the requirements of the soil, the microcontroller activates a holographic projection unit 105 mounted on the body 101 for projecting three-dimensional images relating to the identified need and provide real-time assistance regarding the desired farming operations. The 3D holographic projection unit 105 uses interference patterns of light to create realistic three-dimensional images in mid-air. It typically consists of a laser source, beam splitters, mirrors, and a holographic screen or projection surface. The projection unit 105 projects light onto a surface from multiple angles, using the interference of light waves to produce 3D images visible from different perspectives to provide assistance to the user.

[0040] If the user desires to sow seeds in the desired area, the user provides input through the computing unit and the microcontroller process the input command. Based on the processed input, the microcontroller re-activates the imaging unit 103 to evaluate the position of the specified seeds stored in a multi-sectioned chamber 122 arranged within the body 101. The imaging unit 103 works capture visual data of the multi-sectioned chamber 122 and the seeds stored inside it. The microcontroller analyses the position and arrangement of the seeds to identify the specific seed type and quantity that needs to be dispensed.

[0041] Based on the detected placement of the seeds, the microcontroller actuates a specific motorized iris lid 106 arranged underneath each section of the chamber 122, for opening the specific compartment of the chamber 122 and dispensing an appropriate amount of seeds. The motorized iris lid 106, mentioned herein, consists of a ring in bottom configured with multiple slots along periphery, multiple number of blades and blade actuating ring on the top. The blades are pivotally jointed with blade actuating ring and the base plate 110 are hooked over the blade. The blade actuating ring is rotated clock and antilock wise by a DC motor embedded in ball actuating ring which results in opening of the holes to dispense the seeds.

[0042] The iris lid 106 dispenses the seeds over a conveyer belt 107 attached beneath the chamber 122 and a weight sensor installed on the conveyer belt 107 that detects the presence of the seeds over the belt 107. The weight sensor used herein is a kind of a transducer. The weight sensor depends on the conversion of a load into an electronic signal. The signal is a change in voltage or current otherwise a frequency on the basis of load and the signal is sent to the microcontroller for processing in order to monitor weight of seeds.

[0043] Based on the detected presence of seeds, the microcontroller synchronously activates the conveyer belt 107 to translate the seeds. The conveyor has a belt 107 supported around two rollers which rotate in order to move the belt 107. The conveyor is powered by a DC (direct current) motor that drives a pulley, which rotate and move the belt 107 along its length. The belt 107, typically made of durable materials like rubber or PVC, carries items from one end to the other. Simultaneously, the weight sensor detects the dispersion of seeds into the members 109 and accordingly the microcontroller regulates operation of the conveyer belt 107 and pushers for ensuring uniform seed distribution.

[0044] The conveyor is installed with a bar 108 connect to the underneath of the belt 107. As the belt 107 translate the seeds gradually, the microcontroller actuates a L-shaped linear pusher plate 110 mounted on the conveyer belt 107 to apply an optimal force onto the seeds for dispensing the seeds. The linear pusher plate 110 push seeds from the conveyor belt 107 into the desired dispensing position. When activated by the microcontroller, the pusher plate 110 moves in a controlled, linear motion along a set path. This motion is powered by a motor which is connected to the pusher plate 110 via a mechanical linkage. The linear movement ensures that seeds are pushed steadily and evenly without being scattered or misaligned.

[0045] The dispensed seeds are collected in to a plurality of frustum-shaped members 109 attached with the bar 108. The conveyer belt 107 attachments and the bar 108 is integrated with a Whitworth quick return assembly 111, actuated by the microcontroller for applying an optimal force onto the members 109 to get inserted into the soil and dig a hole at an optimal depth into soil of the selected area. The assembly 111 consists of a crank, a ram, and a link, where the crank is rotated by a motor or other mechanical source of power. As the crank rotates, it drives the ram in one direction quickly (the return stroke), while the force applied in the opposite direction (the forward stroke) is slower and more controlled. The faster return stroke helps in quickly repositioning the members 109 after digging, allowing for efficient planting operations. When the members 109 are driven into the soil, they create holes at an optimal depth, and this ensures that the soil is properly disturbed for seed placement.

[0046] Each of the structure 124 and member 109 is embedded with a depth sensor that detects the depth of the cavity and hole, respectively. The depth sensor used herein is an ultrasonic sensor, the sensor emits sound waves toward the soil and measures the time it takes for the sound waves to bounce back after hitting the surface of the cavity or hole. The sensor then calculates the distance based on the speed of sound and the time delay, providing an accurate reading of the depth. Based on the detected depth, the microcontroller regulates operation of the slider 115 and quick return assembly 111 in view of ensuring precise and accurate planting with minimal manual intervention.

[0047] Once the hole is dig, the microcontroller activates a motorized iris aperture 112 installed at a lower portion of the members 109 to open and dispense the seeds into the dug holes for precise seed plantation. The motorized iris aperture 112 works in the same manner as the motorized iris lid 106 described earlier to dispense the seeds into the dug holes.

[0048] Further, if user desires to sow saplings in the targeted areas, the user provides the input through the computing unit that is processed by the microcontroller. The body 101 is arranged with an elongated cylindrical unit 113 that is equipped with a hopper 114 at a top portion. Based on the processed input, the microcontroller actuates a robotic arm 123 installed on the body 101 in sync with the imaging unit 103 to access a container 125 storing multiple saplings. The robotic arm 123 grabs a sapling from the container 125 and feed into the hopper 114.

[0049] The robotic arm 123 comprises, motor controllers, arm 123, end effector and sensors. All these parts are configured with the microcontroller. The elbow is at the middle section of the arm 123 that allows the upper part of the arm 123 to move the lower section independently. Lastly, the wrist is at the tip of the upper arm 123 and attached to the end effector thereby the end effector works as a hand to pick the sapling from the container 125 and place in the hopper 114. Upon placing the sapling in the hopper 114, the microcontroller re-actuates the wheels 102 moves the body 101 for aligning the unit over the selected areas.

[0050] The cylindrical unit 113 is installed on the body 101 via a slider 115 or providing downward translation to the cylindrical unit 113. The slider 115 consists of a linear guide that allows the cylindrical unit 113 to slide smoothly along a fixed path. The slider 115 is connected to a motor that is activated by the microcontroller to move the cylindrical unit 113 in a precise direction. When the microcontroller receives the appropriate input, it activates the motor connected to the slider 115, which translates the cylindrical unit 113 downward. This downward movement allows the conical structure 124 at the bottom of the cylindrical unit 113 to penetrate the soil, creating a cavity at the selected area.

[0051] The cylindrical unit 113 is configured with a conical structure 124 installed at a bottom portion that is inserted into the soil in a manner that a cavity is created in the selected area. Upon successful insertion of the structure 124, the microcontroller activates a motorized iris gate 116 attached underneath the structure 124 to open and dispense the sapling from the hollow cylindrical unit 113 into the cavity. The motorized iris gate 116 works in the same manner as the motorized iris lid 106 described earlier to dispense the sapling in a precise manner.

[0052] Once the sapling is placed, the microcontroller actuates a pair of L-shaped links 117 installed on lateral sides of the cylindrical unit 113 via a motorized ball and socket joint 118 for distributing the soil over the cavity. The ball and socket joint 118 provides a 360-degree rotation to the links 117 for aiding the links 117 to turn at a desired angle. The ball and socket joint 118 is a coupling consisting of a ball joint 118 securely locked within a socket joint 118, where the ball joint 118 is able to move in a 360-dgree rotation within the socket thus, providing the required rotational motion to the links 117. The ball and socket joint 118 is powered by a DC (direct current) motor that is actuated by the microcontroller thus providing multidirectional movement to ensure proper coverage and soil compaction.

[0053] In addition, the device includes a fluorescence sensor is mounted on the body 101 and synced with the imaging unit 103 for detecting presence of weed plants. The fluorescence sensor works by detecting the unique light emission (fluorescence) produced by plants when they absorb specific wavelengths of light, typically ultraviolet (UV) light. When the sensor emits UV light onto the plants, the chlorophyll and other pigments in the plants absorb the energy and re-emit it as a different wavelength, usually in the visible spectrum. This emitted light is then detected by the fluorescence sensor. Since weeds and crops may have different chemical compositions and pigment levels, they will emit different fluorescence signals. The sensor processes these signals and identifies the presence of weeds based on the distinct fluorescence characteristics.

[0054] If the presence of weed plants is detected, the microcontroller actuates a robotic gripper 119 installed on the body 101 to remove the weed from the selected areas to provide proper growing conditions and promote plants growth. The robotic gripper 119 comprises of motor controllers, jaw, end effector and sensors. All these parts are configured with the microcontroller. The elbow is at the middle section of the jaw that allows the upper part of the jaw to move the lower section independently. Lastly, the wrist is at the tip of the upper jaw and attached to the end effector which is further attached with the gripper 119. The gripper 119 comprise an electric motor and linked with the microcontroller. The microcontroller provides a signal relating to the force, and its motor carries out the gripping of the weed plant.

[0055] To avoid further growth of the weeds, the device also includes an electronic nozzle 120 assembled on the body 101, activated by the microcontroller for spraying a pressurized flow of water onto the invasive plants roots, to trim the roots. The water is stored in a vessel 121 configured with the nozzle 120. The electronic nozzle 120 comprises of a gate 116 and a magnetic coil which uses electricity from
microcontroller to generate the force to control the opening/closing of gate 116 to
control the flow of the water through a small aperture 112 of the nozzle 120,
allowing for precise control of the flow of the water on the removed plant roots, ensuring effective weed removal.

[0056] The microcontroller is integrated with a GPS (Global Positioning System) module for fetching real-time location of the body 101. The GPS module receives signals from multiple satellites in the GPS constellation. Each satellite transmits a signal that includes its position and the precise time of the signal. The GPS module uses these signals to calculate the distance from each satellite based on the time it took for the signal to reach the module. By receiving signals from multiple satellites, the module performs trilateration and calculates the exact position (latitude, longitude, and altitude) of the platform. The microcontroller receives the GPS coordinates and based on the real-time location, the microcontroller regulates operation of the wheels 102 to navigate over the field terrain to perform designated operations, and optimize farming activities.

[0057] The body 101 is installed with a solar panel for harnessing solar energy that is converted to an electrical energy. The solar panel works by converting sunlight into electricity through the photovoltaic (PV) effect. The panel is made up of many solar cells, which are typically composed of semiconductor materials like silicon. When sunlight hits the surface of these cells, photons from the light energy are absorbed by the semiconductor material, exciting electrons and causing them to move. This movement of electrons generates an electric current.

[0058] The energy is further stored in a battery (not shown in figure) associated with the device for powering up electrical and electronically operated components associated with the device. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0059] The present invention works best in the following manner, where the body 101 is configured with the plurality of motorized wheels 102 for providing mobility to the body 101 on an agricultural field. The user access the user interface is installed in a computing unit wirelessly linked with the body 101 to provide input commands for a desired farming operation. Once the input is received, the microcontroller processes the command and activates the imaging unit 103, which uses a camera to scan the field. The images are then processed to generate a 3D map, providing detailed information about soil conditions such as moisture, texture, pH, and compaction. This map helps the device determine the best irrigation schedules, fertilizer application, and other agricultural needs. Once the area is selected, the motorized wheels 102 move the device to the target location. The base of the body 101 houses a motorized hinged flap, which collects soil samples from the designated area. The flap is operated by a motor that ensures precise sample collection. The device’s sensors, integrated with the hinge, detect soil conditions, providing real-time data on soil health and needs. For planting, the device uses imaging to identify and evaluate seed positions in the multi-compartment chamber 122. The microcontroller then actuates a motorized iris lid 106 to release the seeds, which are moved along a conveyor belt 107. The L-shaped pusher plate 110 applies optimal force, ensuring even seed distribution into the soil. The Whitworth quick return assembly 111 is then employed to create holes at the correct depth for the seeds. Additionally, the robotic arm 123 handles sapling placement, while depth sensors ensure precision in planting. The fluorescence sensor detects weeds and activates the robotic gripper 119 to remove them. Powered by solar energy stored in the battery, the device uses GPS module to navigate and complete farming tasks efficiently, with minimal human intervention.
