BACKGROUND OF THE INVENTION

[0002] Stump grinding is a process that grinds a tree stump into wood chips. Stump grinding and root removal are essential processes in land clearing, landscaping, and forestry management. Traditional methods for stump grinding and root removal such as manual digging, chemical treatments, or using basic mechanical grinders, can be time-consuming, labour-intensive, and inefficient. Leftover stumps and roots not only create obstacles in land development but can also attract pests, promote fungal growth, and cause potential hazards. Additionally, deep or widespread roots can interfere with underground utilities, making their removal necessary for construction projects and maintaining infrastructure safety. This creates a pressing need for a device that can aid in improving efficiency, precision, and safety in stump grinding and root removal. Automation can enhance the grinding process by integrating advanced cutting mechanisms, robotic control, and real-time depth adjustments, reducing the need for extensive manual labour. Additionally, automated machines can work faster and with greater consistency, ensuring complete root removal while reducing environmental impact. With growing demands for efficient land clearing and eco-friendly landscaping solutions.

[0003] Traditionally, various equipment is used for stump grinding and root removal, including stump grinders, excavators, root rakes, and mulchers. Stump grinders, available in handheld, walk-behind, and large industrial models, use rotating cutting discs to break down stumps into wood chips. Excavators equipped with specialized attachments like stump shears or hydraulic grinders can remove both stumps and deep root systems. Root rakes help clear out remaining roots and debris, while mulchers shred stumps and roots into fine particles for easier disposal or soil enrichment. Root rakes may leave behind smaller root fragments, leading to potential regrowth. Mulchers, although useful, may not fully extract deeply embedded roots, requiring additional manual work. Furthermore, operating heavy machinery poses safety risks, including flying debris and accidental damage to underground utilities. These challenges highlight the need for more efficient, environmentally friendly, and user-friendly stump grinding and root removal solutions.

[0020] 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.

[0021] The present invention relates to automated stump grinding and root removal device that that is capable of efficiently removing stumps from a ground by involving a series of steps like sensing, cutting, and suction to perform precise stump grinding and root removal, thus optimizing energy use and minimizing human effort.

[0022] Referring to Figure 1, an isometric view of an automated stump grinding and root removal device is illustrated, comprises of a body 101, configured with a plurality of motorized omnidirectional wheels 102, a touch interactive display panel 103 is mounted on the body 101, an artificial intelligence-based imaging unit 104 installed on the body 101, an L-shaped extendable pole 105, mounted on the body 101, a sensing module 106 installed on the L-shaped extendable pole, a motorized cutting unit 107 installed on the free-end of pole, a motorized helical digger 108 mounted with a L-shaped extendable rod 109 on the platform.

[0023] Figure 1 further comprises of a suction unit 110 mounted on the body 101 by means of an extendable hollow cylindrical member 111, a chamber 112 installed in the body 101, a hydraulic pusher 113 installed at a ceiling portion of the chamber 112, a plate 114 arranged with the pusher, a flap 115 installed on the body 101 via a robotic link 116, a vibrating unit 117 is integrated in the member, a solar panel 118 is positioned on the body 101 via an extendable bar 119 with a motorized ball-and-socket joint 120

[0024] The proposed device comprises of a body 101 configured with a plurality of motorized omnidirectional wheels 102for providing mobility to the body 101 over a ground surface. The user activates the device through a push button associated with the device. The push button has an outer casing and an inner mechanism, including a spring and metal contacts. When the button is pressed, it pushes down on the spring-loaded mechanism inside. In the default state, the internal contacts are apart, so the circuit is open and no electricity flows. Pressing the button makes the contacts touch each other, closing the circuit and allowing electricity to flow and activate the device. The device in turn activates an inbuilt microcontroller that is pre-fed with a defined set of instructions to perform various functions. When the button is released, the spring pushes it back to its original position

[0025] Post activation of the device, the microcontroller activates a touch interactive display panel 103 is mounted on the body 101 for enabling a user to provide input commands for removal of a stump from the surface. The touch interactive display panel 103 as mentioned herein is typically an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers.

[0026] A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding for removal of the stump from the surface A touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit)

[0027] After processing the input commands, the microcontroller activates an artificial intelligence-based imaging unit 104 installed on the body 101 and paired with a processor for capturing and processing multiple images in vicinity of the body 101, respectively to generate a three-dimensional map of surroundings, the generated mapping are displayed onto the display panel 103 for allowing the user to select a desired stump that is to be removed.

[0028] The imaging unit 104 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the body 101 and the captured images are stored within a memory of the imaging unit 104 in form of an optical data. The imaging unit 104 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images.

[0029] The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and to generate a three-dimensional mapping of surroundings, wherein the generated mapping are displayed onto the display panel 103 for allowing the user to select a desired stump that is to be removed.

[0030] Based on desired stump that is to be removed which the microcontroller actuates the wheels to provide movement to the body 101 in proximity to the selected stump. The motorized omnidirectional wheels 102 facilitate smooth and controlled movement across the surface. Each wheel is mounted on a swiveling axle, allowing for 360-degree rotation, which enables the platform to navigate easily around obstacles and uneven surface. 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, causing the wheel to spin to provide movement to the body 101 in proximity to the selected stump

[0031] Upon positioning the body 101 in proximity to the selected stump. The microcontroller activates an L-shaped extendable pole, mounted on the body 101 to extend/retract for positioning a free-end of the pole over the stump. The L-shaped extendable pole 105 is powered by a pneumatic unit that embodies an air compressor, air cylinder, air valves, and piston which work in collaboration to perform the extension and retraction of the pole. The pole comprises a nested tube arrangement that contains multiple hollow tubes connected concentrically.

[0032] The air cylinder is attached to the bottom of the nested tube arrangement and further consists of an air piston attached to the topmost part of the nested tube arrangement from the inside. The air cylinder is integrated with one inlet and one outlet valve that is connected to an air compressor. The air compressor draws air from the surroundings and compresses it to form pressurized air which enters the inlet valve and creates a force that pushes the piston in the forward direction. As the piston moves in the forward direction, it leads to the sequential opening of the concentrically connected tubes from the top toward the bottom. This leads to the extension of the pole for positioning the free-end of the pole over the stump.

[0033] Post positioning the free-end of the pole over the stump, the microcontroller activates a sensing module 106 installed on the L-shaped extendable pole 105 for detecting the stump’s characteristics including but not limited to wood type, hardness and moisture levels of the stump. The sensing module 106 analyzes a stump’s characteristics using a combination of sensors. A near-infrared (NIR) spectrometer detects wood type by analyzing light absorption patterns unique to different species.

[0034] A durometer measures hardness by assessing resistance to indentation or sound wave propagation. A moisture sensor, using capacitance or resistance measurement, determines water content by detecting changes in electrical properties. Data from these sensors is processed by the microcontroller, which applies pre-trained module for detecting the stump’s characteristics including but not limited to wood type, hardness and moisture levels of the stump

[0035] Post detecting the stump’s characteristics, the microcontroller activates a motorized cutting unit 107 installed on the free-end of pole for rotating at an optimum speed to precisely cut the stump. the cutting unit 107 includes a plurality of blades installed at peripheral portion of a disc, via a motorized hinge joint that adjusts angle of the blades for precise alignment over the stump’s surface. The motorized hinge joint used herein comprises of two parts, one part of the hinge has a cylindrical shape, while the other part has a corresponding groove to fit the first part over it.

[0036] This configuration allows the hinge to pivot around a fixed axis. The joint is powered by a motor to provide a rotational force that is transmitted through a mechanical linkage that to the hinge joint. This might involve gears, belts, or direct coupling. The transmission mechanism converts the motor’s rotational force into movement of the hinge joint which allows the joint to rotate around its axis, guided by the motor’s movement that adjusts angle of the blades for precise alignment over the stump’s surface

[0037] Further the microcontroller activates motorized cutting unit 107 installed on the free-end of pole for rotating at an optimum speed to precisely cut the stump the. The motorized cutting unit 107 operates by using an electric motor to drive a spinning blade for cutting the stump. When the cutter is actuated, electricity flows into the motor, which converts this electrical energy into rotational motion. This spinning motion is then transferred to the cutting blade, causing it to turn rapidly. As the blade spins, the sharp edge slices through the stump to to precisely cut the stump.

[0038] After cutting the stump the microcontroller activates a GPR (Ground Penetrating Radar) sensor coupled with a depth sensor, is installed on the body 101 for determining depth of the stump in the ground surface. The ground penetrating radar (GPR) sensor coupled with a depth sensor determines the depth of a stump by transmitting high-frequency electromagnetic waves into the ground. When these waves encounter a boundary between different materials, such as soil and wood, a portion of the signal reflects to the receiver.

[0039] The GPR records the time delay between transmission and reception, which is processed to estimate depth. A depth sensor, such as LiDAR sensor, enhances accuracy by measuring surface elevation variations. The combined data is processed using signal analysis protocols to filter noise and adjust for soil composition. By integrating both sensors, the module provides precise depth measurements, for determining depth of the stump in the ground surface.

[0040] Post determining the depth of the stump in the ground surface, the microcontroller activates a L-shaped extendable rod 109 on the platform for extending a motorized helical digger. The extendable rod mentioned herein works same as L-shaped extendable pole. Upon positioning the motorized helical digger attached on the pole, that is actuated by the microcontroller for drilling base surface around the stump, to allow ground penetrated portion of the stump to also get removed.

[0041] The motorized helical digger operates by rotating a helical auger blade powered by an electric motor. As the auger rotates, its cutting edges penetrate the base surface, breaking and displacing soil. The helical structure facilitates continuous lifting of loosened soil to the surface, preventing clogging and ensuring efficient excavation. Torque and rotational speed are controlled to adapt to soil hardness and density. The auger’s depth increases progressively, ensuring thorough drilling around the stump. Once the base is sufficiently drilled, the loosened ground allows easier removal of the stump’s underground portion, to allow ground penetrated portion of the stump to also get removed

[0042] After penetrating the stump, the microcontroller activates an extendable hollow cylindrical member 111 for extending to position a suction unit 110 mounted on the member. The extendable hollow cylindrical member 111 used herein works same as above mentioned working of L-shaped extendable bar. Upon positioning the suction unit 110 in proximity to the cut stump, the microcontroller a suction unit 110 to extract the cut pieces that are transferred to a chamber 112 installed in the body 101 through the member, for collecting the cut pieces into the chamber 112.

[0043] The suction unit 110 consists of a pump that operates by creating a vacuum to surface. The pump is activated for drawing the air in through an intake. Inside the pump, a rotating impeller moves to reduce the pressure within the pump chamber 112. This reduction in pressure creates a vacuum effect, which generates suction and to extract the cut pieces that are transferred to the chamber 112 installed in the body 101 through the member, for collecting the cut pieces into the chamber 112.

[0044] Upon collecting the cut pieces into the chamber 112, the microcontroller activates an ultrasonic sensor installed in the chamber 112 and synced with the imaging unit 104 for identifying filling of the chamber 112 with collected pieces. The ultrasonic sensor emits high-frequency sound waves inside the chamber 112 and measures the time taken for the reflected waves to return from the collected pieces. As the chamber 112 fills, the distance between the sensor and the material decreases, altering the reflection time. The imaging unit 104 processes this data by syncing it with visual inputs to verify material accumulation levels. When the detected level reaches a predefined threshold, the microcontroller triggers an alert or stops further collection.

[0045] Based on identifying filling of the chamber 112 with collected pieces, the microcontroller activates a hydraulic pusher 113 installed at a ceiling portion of the chamber 112, for pushing a plate 114 arranged with the pusher against the collected pieces in view of compressing the pieces to maximize storage space within the chamber 112 for efficient collection of the cut pieces.

[0046] The hydraulic pusher 113 used herein is powered by a hydraulic unit consisting of a hydraulic cylinder, hydraulic compressor, hydraulic valve and piston that work in collaboration for providing the required extension/retraction to the rod. The microcontroller actuates the valve to allow passage of hydraulic fluid from the compressor within the cylinder, the hydraulic fluid further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the pusher and due to applied pressure the pusher extends for pushing the plate 114 against the collected pieces in view of compressing the pieces to maximize storage space within the chamber 112 for efficient collection of the cut pieces.

[0047] Upon successful removal of stump and cut pieces, the microcontroller activates a robotic link 116 to provide controlled movement to the flap 115 installed on link to provide controlled movement to the plate 114 for redistributing soil around dug hole left on the stump’s position, in view of finishing the surface, thereby facilitating in efficient removal of the stump from the surface. The robotic link 116 contains an end effector and several segments that are attached together by motorized joints also referred to as axes.

[0048] Each joints of the segments contains a step motor that rotates and allows the robotic arm to complete a specific motion in translating the equipped end effector. The end effector further comprises of the flap 115 hinged with each other by means of a bi-directional step motorto provide controlled movement to the plate 114 for redistributing soil around dug hole left on the stump’s position, in view of finishing the surface, thereby facilitating in efficient removal of the stump from the surface.

[0049] Additionally, the device includes a vibrating unit 117 is integrated in the member for generating vibrational sensations to dislodge soil particles from the cut pieces that are collected at the bottom of the chamber 112. The vibrating unit 117 generates controlled vibrations using an eccentric rotating mass (ERM) powered by an electric motor. When activated, the unbalanced mass rotates or oscillates, creating mechanical vibrations that transfer energy to the collected cut pieces. These vibrations disrupt adhesion forces between soil particles and the surface of the pieces, causing the loose particles to detach. The vibration intensity and frequency are optimized based on soil composition and particle size.

[0050] The device incorporates a sun sensor installed on the body 101 to detects radiation. The sun sensor detects the sun's position consists of a combination of light sensors such as photodiodes that are strategically placed to detect the intensity of sunlight from different directions. These sensors continuously measure the angle and strength of incoming light, allowing the sensor to determine the sun's position relative to the platform. The microcontroller processes this data and calculate the intensity of sunlight.

[0051] Once detected, the microcontroller activates an extendable bar 119 with a motorized ball-and-socket joint 120 that adjusts angle of a solar panel 118 is positioned on motorized ball-and-socket joint. The extendable bar 119 mentioned herein works same as mentioned above working of L-shaped extendable pole. Further the motorized ball and socket joint allows for smooth, adjustable movement in various directions. The joint has a ball-shaped part that fits into a cup-like socket. A motor controls this ball, making the ball move around inside the socket. Actuators adjust the ball’s position to ensure it moves accurately and flexibly, enabling precise control and positioning in multiple directions that adjusts angle of the panel.

[0052] Upon adjusting the microcontroller activates the solar panel 118 attached on the ball and socket joint where solar energy that is further converted to electrical energy. The solar energy is converted into electrical energy through photovoltaic (PV) cells made of semiconductor materials like silicon. When sunlight strikes the PV cell, photons excite electrons, creating an electric field that generates direct current (DC) electricity. This DC electricity flows through conductive layers and is regulated by a charge controller to prevent overcharging. An inverter then converts the DC into alternating current (AC) for powering electrical devices.

[0053] The extra energy harnessed by the solar panel is stored in a battery that is installed within the device which is connected to the microcontroller. The battery supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner.

[0054] The present invention works best in the following manner, where the body 101 as disclosed in the invention is configured with the plurality of motorized omnidirectional wheels 102 for mobility over the ground surface. The device is activated through the push button, which engages the microcontroller pre-fed with instructions. Post activation, the microcontroller enables the touch interactive display panel 103 for user input regarding stump removal. The artificial intelligence-based imaging unit 104 captures images, generating a three-dimensional mapping displayed on the panel for stump selection. Upon selection, the microcontroller actuates the motorized omnidirectional wheels 102 to position the body 101 near the stump. The L-shaped extendable pole, powered by the pneumatic unit, extends to position its free-end over the stump. The sensing module 106 on the pole detects the stump’s characteristics, including wood type, hardness, and moisture levels.

[0055] In continuation, based on this data, the microcontroller activates the motorized cutting unit 107 with a motorized hinge joint to align and cut the stump precisely. The GPR sensor coupled with the depth sensor determines stump depth. The motorized helical digger, mounted on the L-shaped extendable rod, drills the base around the stump to facilitate removal. The suction unit, positioned via the extendable hollow cylindrical member, extracts and transfers cut pieces into the chamber 112. The ultrasonic sensor, synced with the imaging unit, monitors chamber 112 filling. The hydraulic pusher 113 compresses cut pieces for space optimization. The robotic link 116 and flap 115 redistribute soil, restoring surface integrity. The vibrating unit 117 dislodges soil particles from collected pieces. The sun sensor detects solar radiation, adjusting the solar panel 118 via the motorized ball-and-socket joint 120 for optimal energy conversion into electricity through photovoltaic cells.
