BACKGROUND OF THE INVENTION

[0002] Cultivation of rice is a labor-intensive agricultural activity that requires extensive land availability, a constant water supply, and manual workforce for sowing, monitoring, and harvesting. In many regions, the shortage of arable land due to urbanization, climate change, or waterlogging creates limitations in growing rice using traditional field-based farming practices. Additionally, the labor required for manually planting and harvesting rice makes the process time-consuming, inefficient, and cost-heavy, especially in remote or flood-prone areas.

[0003] Traditional rice farming methods also pose limitations in terms of controlling and optimizing environmental factors essential for healthy crop growth. Farmers are often unable to monitor or manage conditions such as water quality, sunlight exposure, or the presence of diseases in crops, which may lead to low yield and crop failure. Furthermore, the reliance on natural rainfall, unpredictable weather patterns, and unregulated irrigation makes it difficult to maintain uniform crop quality and consistency.

[0004] Manual intervention is also required at multiple stages of the rice cultivation cycle from planting saplings in proper alignment, ensuring adequate spacing, irrigating regularly, checking for pest infestation, to finally harvesting the crops. These processes not only demand skilled labor but also involve significant physical effort and time, which could otherwise be optimized using automation and remote management.

The invention solves the technical problems that a driver needs to observe the height of the header in real time and adjusts the height of the header by using the operating handle, and reduces the labour intensity of the driver and the proficiency requirement on the driver.

[0007] As discussed in the aforementioned prior arts, although various devices and systems for harvesting rice are available, most of these are land-based and are not suitable for regions where water bodies are abundant and farmlands are limited. Additionally, these conventional devices and systems lack environmental sensing, disease detection and autonomous navigation, which makes harvesting insufficient for addressing farming challenges.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that enables automated farming over water bodies. In addition, the device should ensure proper planting, environmental monitoring, water management, and harvesting while minimizing human intervention, enhancing productivity, and promoting sustainable rice farming even in non-traditional agricultural terrains.

[0025] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0026] The present invention relates to a floatable rice irrigation and harvesting device that is accessed by a user for harvesting rice crops on water bodies by means of automated navigation, growth monitoring, irrigation, and harvesting. In addition, the device further identifies environmental conditions such as sunlight and wind speed to take preventive and corrective measures for promoting healthy crop development, along with detecting diseased saplings and removing them in order to enhance the overall crop yield.

[0027] Referring to Figure 1 and Figure 2, an isometric view of a floatable rice irrigation and harvesting device and a bottom view of the device are illustrated, comprising a frame 101 having a plurality of hollow cuboidal bodies 102, a chamber 107 is configured with each of the bodies 102, plurality of motorized propellers 103 is configured with the frame 101 via hinges 104, an artificial intelligence-based imaging unit 105 is mounted on each of the bodies 102, a telescopically operated gripper 106 is arranged with each of the chambers 107, an electronic valve 108 is configured with a container 109, installed with the frame 101, a first pump 301 embedded with the container 109, a sensing module 302 is installed within the container 109, a plurality of electronic sprayers 110 installed with the bodies 102, a second pump 303 configured with the container 109, a water filtration unit 304 paired with the second pump 303, water filtration unit 304 includes a body 304a installed with a set of filter members 304b, a set of hollow cuboidal members 201 installed underneath the body 102 and each configured at a plurality of iris pores 202, a disc 111 installed with each of the bodies 102 via a robotic link 112, and configured with a circular plate 113, a blade 114 installed with the plate 113, a gear arrangement 115 configured between the disc 111 and plate 113, the gear arrangement 115 includes a motorized sprocket 115a assembled on the disc 111 and installed with a drive chain 115b, a set of extendable plates 116 configured along edges of each of the bodies 102, a plurality of motorized iris lids 117 is configured on each of the plates 116 and a light reflector 118 installed on the frame 101 via a plurality of motorized ball and socket joints 119.

[0028] The device disclosed herein comprises a frame 101, which serves as a main structure of the device and is developed to be utilized by a user for harvesting rice. The frame 101 is designed for the efficient cultivation and harvesting of rice crops directly on water bodies 102. The frame 101 having a plurality of hollow cuboidal bodies 102, which float on the surface of a water body for creating self-sustained solution that supports rice growth.

[0029] Each of these cuboidal bodies 102 is partially filled with soil to support the growth of rice saplings. With each cuboidal body 102, there is a chamber 107 configured specifically for holding rice saplings. These chambers 107 are strategically positioned near the bank of the water body initially and act as a nursery for saplings before they are transplanted. The floating nature of the bodies 102 allows them to be maneuvered across the water surface, making the device dynamic and scalable.

[0030] The device is wirelessly linked with a computing unit having a user interface that allows a user to input commands wirelessly for growing the saplings. These commands are processed by an inbuilt microcontroller, which interprets the user's instructions and transmits signals to a series of motorized propellers 103, which are attached to the frame 101 and enable it to maneuver across the water surface, particularly from the bank to the middle of the water body.

[0031] The motorized propeller consists of an electric motor and a propeller blade 114. The propeller is designed to have an airfoil shape and when an electric current flows through the motor windings, it generates a rotating magnetic field. The electric motor’s rotating magnetic field interacts with the permanent magnets inside the motor, causing the motor’s rotor to turn. This rotation of the rotor spins the propeller blade 114. As the propeller blade 114 rotates, it creates thrust by moving the water. This thrust is generated due to the pressure difference between the front and back surfaces of the propeller blade 114, which results in the forward motion of the frame 101.

[0032] The speed and direction of the propeller blades 114 are controlled by varying the electric current supplied to the motor. The microcontroller by increasing and decreasing the current and altering its direction, changes the speed and direction of the propeller’s rotation, thereby allowing controlled movement for optimal positioning of the frame 101 towards middle of the water body for growth and harvesting operations.

[0033] To ensure accurate planting of rice saplings, each cuboidal body 102 is outfitted with an artificial intelligence-based imaging unit 105 paired with a processor to detect the precise location of each rice sapling within its respective chamber. The artificial intelligence based imaging unit 105 is constructed with a camera lens and a processor, wherein the camera lens is adapted to capture a series of images of the chamber. The processor carries out a sequence of image processing operations including pre-processing, feature extraction, and classification by utilizing artificial intelligence and machine learning.

[0034] The image captured by the imaging unit 105 is real-time images of the chamber. The artificial intelligence based imaging unit 105 transmits the captured image signal in the form of digital bits to the microcontroller. The microcontroller upon receiving the image signals compares the received image signal with the pre-fed data stored in a database and constantly determines precise location of each rice sapling within its respective chamber.

[0035] Upon detection, the microcontroller activates a telescopic gripper 106 that is integrated within each chamber 107 for carefully gripping and transferring the saplings into the soil present in the cuboidal bodies 102. The telescopic gripper 106 mentioned above basically consist of multiple cylindrical sections with one section sliding inside the other and an end effector like a gripper 106. The gripper 106 includes a pair of flaps which are pivoted with each other for allowing the axial motion of the flaps required for ripping and transferring the saplings into the soil present in the cuboidal bodies 102. In an embodiment of the present invention, the gripper 106 as mentioned herein are powered by a pneumatic unit that utilizes compressed air to extend and retract the telescopic gripper 106.

[0036] The process begins with an air compressor which compresses atmospheric air to a higher pressure. The air cylinder of the pneumatic unit contains a piston that moves back and forth within the cylinder. The cylinder is connected to one end of the gripper 106. The piston is attached to the telescopic gripper 106 and its movement is controlled by the flow of compressed air. To extend the telescopic gripper 106 piston activates the air valve 108 to allow compressed air to flow into the chamber 107 behind the piston.

[0037] As the pressure increases in the chamber, the piston pushes the telescopic gripper 106 to the desired length for gripping and transferring the saplings into the soil present in the cuboidal bodies 102. The saplings are planted in rows, with the grippers 106 ensuring appropriate spacing between adjacent plants for healthy growth, thereby ensures consistency and efficiency in the transplantation process.

[0038] An electronic valve 108 is installed on a container 109 (as illustrated in Fig 3) integrated into the frame 101 and is actuated by the microcontroller to allow the collection of water from the surrounding environment using a first pump 301 embedded within the container 109. The electronic valve 108 works by utilizing electrical energy to automize the flow solution in a controlled flow pattern by converting the pressure energy of a fluid into kinetic energy, which increases the fluid's velocity. Upon actuation of valve 108 by the microcontroller, the first pump 301 allows the collection of water from the surrounding environment, increasing its pressure significantly.

[0039] After collecting the water, the microcontroller actuates a sensing module 302, positioned inside the container 109 to monitor the condition of the collected water. The sensing module 302 includes a pH sensor, a salinity sensor, and a turbidity sensor. These sensors assess the suitability of the water for irrigation by measuring its pH level, salinity content, and turbidity. This evaluation is crucial for maintaining the ideal conditions for rice sapling growth.

[0040] The pH sensor consists of a probe, usually made of glass or a special polymer, with a thin bulb at the end. This bulb contains a solution with known pH. A reference electrode is fabricated within the probe that remains at a constant pH, providing a stable reference point for comparison of pH of the collected water. The thin bulb contains an ion selective electrode that selectively interacts with the hydrogen ions in the collected water. This interaction generates a voltage proportional to the pH of the collected water. The generated voltage is sent to the microcontroller.

[0041] The salinity sensor measures the concentration of dissolved salts in water. In an embodiment of the present invention, the salinity sensor is typically conductivity sensor, which works on the principle that the electrical conductivity of water increases with the concentration of dissolved salts. The sensor consists of two electrodes, typically made of stainless steel or titanium, that are submerged in the water. When an alternating current (AC) is applied across the electrodes, the ions in the water (such as sodium, chloride, and calcium) conduct electricity, allowing the sensor to measure the conductivity of the water. The conductivity reading is then converted into a salinity reading, usually expressed in parts per thousand (ppt) or practical salinity units (PSU) to determine if the water is suitable for irrigation.

[0042] On the other hand, the turbidity sensor measures the cloudiness or haziness of water caused by suspended particles, such as sediment, algae, or other impurities. In an embodiment of the present invention, the turbidity sensor is optical sensor, which uses light to measure the scattering of particles in the water. The sensor consists of a light source, usually an infrared LED, and a photodetector, which is positioned at a 90-degree angle to the light source.

[0043] When the light is emitted into the water, it scatters off the suspended particles, and the photodetector measures the amount of scattered light. The more particles present in the water, the more light is scattered, resulting in a higher turbidity reading. The sensor converts the scattered light into a turbidity reading, usually expressed in Nephelometric Turbidity Units (NTU) or Formazin Nephelometric Units (FNU) for identifying potential issues with sediment or algae growth.

[0044] If the sensing module 302 determines that the collected water is unsuitable for irrigation, the microcontroller activates a second pump 303 which channels the water into a filtration unit 304. This filtration unit 304 comprises a body 304a filled with multiple sequential filter members 304b that purify the water. Once filtered, the water is sprayed via a series of electronic sprayers 110 installed across the bodies 102 and connected to the previously connected container 109 through network of conduits onto the rice saplings using the electronic sprayers 110, ensuring only suitable water reaches the crops and supports their growth.

[0045] To facilitate immersion of the floating bodies 102 for enhanced growth or environmental adaptation, a set of hollow cuboidal members 201 are installed underneath each body 102. These members are integrated with a plurality of motor-controlled iris pores 202. When the sensing module 302 indicates that the surrounding water is of optimal quality, the microcontroller opens these iris pores 202, allowing water from the water body to fill the hollow member. The iris pores 202 are typically composed of a series of thin, overlapping blades or petals arranged in a circular or pattern. The microcontroller sends signals to the motor of the iris pores 202 to get open and the motor rotates or moves the iris blades to open and allowing water from the water body to fill the hollow member, which submerges the frame 101 partially or fully, depending on the requirement, thereby helps in creating a stable microclimate around the saplings and supports root development in submerged conditions.

[0046] Each body 102 is also equipped with a robotic link 112 that supports a disc 111 with a specifically cut portion. This disc 111 is further aligned with a circular plate 113, also featuring a matching cut portion. The microcontroller actuates the robotic link 112 to precisely position the disc 111 around each mature rice plant, as detected by the imaging unit 105. The robotic link 112 is a type of mechanical link which is usually available with similar function to a human arm.

[0047] The segments of such a manipulator are connected by joints allowing either rotational motion or translational displacement. The robotic link 112 contains several segments that are attached together by joints also referred to as axes. The robotic link 112 contains several segments that are attached together by motorized joints also referred to as axes. Each joints of the segments contains a step motor that rotates and allows the robotic link 112 to complete a specific motion in translating the disc 111 around each mature rice plant.

[0048] The alignment of these components ensures that each plant is isolated correctly for harvesting. The disc 111 and plate 113 allows for accurate, automated engagement with individual plants to prepare them for cutting. Harvesting of the rice plants is accomplished via a gear arrangement 115 linked between the disc 111 and the circular plate 113. This arrangement is driven by a motorized sprocket 115a installed on the disc 111 and connected to a drive chain 115b, which meshes with gear teeth located on the inner circumference of the plate 113.

[0049] When the sprocket 115a rotates, it causes the plate 113 to rotate as well. A blade 114 mounted on the plate 113 cuts the rice plant in a clean and efficient manner. Following cutting, the telescopic grippers 106, once again actuated by the microcontroller, collect the harvested plants and place them into a receptacle configured within each cuboidal body 102 for storage and further processing.

[0050] In case the microcontroller via the imaging unit 105 identifies an obstacle in the path of the floating frame 101, the microcontroller immediately engages a set of motorized hinges 104 connected between the frame 101 and the propellers 103. These hinges 104 adjust the orientation of the propellers 103 in real-time, enabling the device to tilt or change direction as necessary to avoid collision. The hinges 104 typically involve the use of an electric motor to control the movement of the hinge and the connected component. The hinges 104 provide the pivot point around which the movement occurs.

[0051] The motor is the core component responsible for generating the rotational motion. It converts the electrical energy into mechanical energy, producing the necessary torque that drives the hinges 104. As the motor rotates, the motorized hinges 104 tilt or change direction of the device as necessary to avoid collision, thereby ensuring smooth, uninterrupted movement of the frame 101 even in cluttered or unpredictable environments.

[0052] An anemometer is installed on one of the floating bodies 102 to monitor ambient wind speed. In an embodiment of the present invention, the anemometer consists of cups, which are designed to catch the wind, causing the anemometer to rotate. As the wind blows, it forces the cups to rotate. The speed of rotation is directly proportional to the wind speed. Faster rotation corresponds to higher wind speeds. The anemometer is equipped with sensors to measure the angular velocity of the rotating cups. The measured angular velocity is then converted into an electrical signal. The electrical signal is then processed by the microcontroller to convert it into a usable wind speed value.

[0053] When wind speed exceeds a predefined threshold, indicating potential risk to the fragile saplings, the microcontroller actuates a series of extendable plates 116 mounted along the edges of each cuboidal body 102. These plates 116 extend outward to shield the saplings from direct wind exposure. In an embodiment of the present invention, the extension of the plate 116 if powered by a drawer arrangement. The drawer arrangement consists of a drawer that typically slides on the rails inside the plate 116.

[0054] These rails provide a smooth and stable path for the extension or retraction of the plate 116. When the microcontroller actuates the drawer arrangement, the motor starts rotating and the rotational motion is converted into linear motion through the use of gears. As the motor rotates, the drawer moves either outward or inward along the sliding rails. This extension or retraction increase and decreases the size of the plate 116 and helps to shield the saplings from direct wind exposure.

[0055] Furthermore, motorized iris lids 117 located on the plates 116 open up, allowing water to pass through and enter the floating bodies 102. This added water weight increases the stability of the structure by lowering its center of gravity and enabling partial submersion, thus anchoring the saplings securely during strong winds.

[0056] If the imaging unit 105 detects that the saplings are receiving inadequate sunlight, a sun sensor determines the direction of maximum sunlight. In an embodiment of the present invention, the sun sensor typically consists of photodiodes or phototransistors that convert light into electrical signals. When sunlight hits the sensor, it generates a voltage proportional to the light intensity. The sensor determines direction of the sun by comparing the output signals. This information is processed by the microcontroller, which then determines the direction of maximum sunlight.

[0057] In response, the microcontroller actuates a series of ball-and-socket joints installed with the frame 101 to reposition light reflectors 118 attached to each joint. The motorized ball and socket joint 119 consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The reflectors 118 are attached to the socket of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint 119 and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the reflectors 118. As the ball and socket joint 119 move, it provides the necessary angular movement to the reflector 118 to reflect maximum sunlight towards the saplings. These reflectors 118 are oriented to reflect and redirect sunlight onto the saplings. This capability ensures consistent light availability even under cloudy or uneven lighting conditions, thereby enhancing photosynthesis and plant growth.

[0058] To prevent the spread of disease among the saplings, the imaging units 105 continuously monitor the health of each plant. If a sapling is detected to be diseased based on visual markers or growth anomalies, the microcontroller instructs the telescopic grippers 106 to gently uproot the affected plant and discard it away from the growing area, thereby ensuring that diseases are contained early and do not affect the surrounding healthy crops.

[0059] The present invention works best in the following manner, where the frame 101 comprising the plurality of hollow cuboidal bodies 102 filled with soil is positioned on the water surface. Each of these hollow cuboidal bodies 102 contains the chamber 107 that is stored with rice saplings. the user provides input commands through the user-interface inbuilt in the computing unit, which is wirelessly linked with the frame 101. These input commands are processed by the inbuilt microcontroller that actuates the plurality of motorized propellers 103 configured with the frame 101, enabling the frame 101 to maneuver towards the middle of the water body. Once positioned, the artificial intelligence-based imaging unit 105 detects the location of the saplings stored within each chamber. Based on this detection, the microcontroller directs the telescopically operated gripper 106 arranged with each chamber 107 to grip and plant the saplings into the soil present within the bodies 102 in multiple rows, ensuring the suitable distance between adjacent saplings. Simultaneously, the electronic valve 108 configured with the container 109 on the frame 101 is actuated by the microcontroller to allow the first pump 301 embedded within the container 109 to collect water from the water body. the sensing module 302 then detects the condition of the collected water. If the sensing module 302 detects that the water is not suitable for the growth of saplings, the microcontroller actuates the second pump 303 also configured with the container 109 to pump the water toward the water filtration unit 304 paired with the pump. This filtered water is then delivered to the plurality of electronic sprayers 110 installed on the bodies 102 via the network of conduits, allowing the saplings to receive clean water for optimal growth. However, if the sensing module 302 confirms the water is suitable for sapling growth, the microcontroller actuates iris pores 202 configured on the set of hollow cuboidal members 201 installed underneath the body 102 to open. This allows water from the water body to fill these members and submerge the frame 101, promoting sapling growth. As the rice plants mature, the disc 111 having the cut portion is installed with each of the bodies 102 through the robotic link 112 and aligned with the circular plate 113 having the matching cut portion.

[0060] In continuation, the microcontroller actuates the robotic link 112 to position the disc 111 around each grown rice plant, as detected by the imaging unit 105, in the successive manner. the gear arrangement 115 configured between the disc 111 and plate 113 is then actuated by the microcontroller to rotate the plate 113 with respect to the disc 111, enabling the blade 114 installed with the plate 113 to cut the plant. Following the cutting operation, the microcontroller actuates the telescopically operated grippers 106 to collect and store the harvested rice plants in the receptacle configured with each of the bodies 102. Additionally, if the imaging unit 105 detects any obstacle in the path of the frame 101, the microcontroller actuates the plurality of motorized hinges 104 configured between the frame 101 and propellers 103 to tilt the propellers 103 in the suitable direction to prevent collision. The sensing module 302 used to detect water condition comprises the pH sensor, salinity sensor, and turbidity sensor. The water filtration unit 304 includes the body 304a installed with the set of filter members 304b in the continuous manner for effective filtering. The gear arrangement 115 used in the cutting mechanism consists of the motorized sprocket 115a assembled on the disc 111 and installed with the drive chain 115b that meshes with teeth carved at the inner periphery of the plate 113, allowing rotation of the plate 113 via the drive chain 115b and teeth. To protect the saplings from environmental damage, the anemometer is configured on one of the bodies 102 to detect wind speed. If the detected wind speed exceeds the threshold value, the microcontroller actuates the set of extendable plates 116 along the edges of each body 102 to deploy for preventing damage to the crops. These plates 116 also include the plurality of motorized iris lids 117 that open to allow water to pass through the plate 116 and fill the bodies 102 for optimal submerged growth. Furthermore, if the imaging unit 105 detects improper sunlight on the saplings, the sun sensor installed on one of the bodies 102 detects the sun's direction.
