DETAILED DESCRIPTION OF THE INVENTION

[0019] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0021] 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.

[0022] The present invention relates to an autonomous green space care device that is developed for maintaining health of outdoor plant areas by detecting environmental changes, alerting caretaker, and also taking necessary protective and care measures, thereby reducing plant damage and promoting year-round growth.

[0023] Referring to Figure 1, an isometric view of an autonomous green space care device is illustrated, comprises of a housing 101 installed with plurality of motorized omnidirectional wheels 102, an artificial intelligence-based imaging unit 103 is installed with the housing 101, a plurality motorized rollers 104 coiled with thermal covers are attached with the body, each via a pair of L-shaped hydraulic pistons 105, a storage unit 106 within the housing 101 divide into multiple compartments, a plurality of motorized clamping units 107 mounted on the body via extendable rods 108 and motorized ball-and-socket joints 109, a motorized air blower 110 installed on the body via an extendable bar 111, a water storage chamber 112 coupled with an electronic control nozzle conduit 113 is provided on the body, a multi-sectioned container 114 connected via a conduit integrated with a motorized valve 115, a speaker 116 and a microphone 117 is integrated with the body, and thermal sheets are embedded with extendable digging pins 118.

[0024] The present invention includes a housing 101 preferably in portable cuboidal shape incorporating various components associated with the device, developed to be positioned on a ground surface. A user is required to access and presses a push button arranged on the housing 101 to activate the device for associated processes of the device.

[0025] The push button when pressed by the user, closes 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 linked components.

[0026] After the activation of the device, the microcontroller actuates plurality of motorized omnidirectional wheels 102 underneath the housing to provide mobility and height adjustment of the motorized thermal covers across the green space. The motorized omnidirectional wheel 102 facilitates smooth and controlled movement across the surface. Each wheel 102 is mounted on a swiveling axle, allowing for free rotation, which enables the user to navigate easily around obstacles and uneven surface. The wheel’s 102 shaft is connected to a motor, activated by the microcontroller that receives electrical power from a power source and convert into mechanical energy by the motor, that provides rotation to the shaft, causing the wheels 102 to spin and position housing in vicinity to the plants.

[0027] Once the housing is positioned, the user is enabled to provide voice command via a microphone 117 mounted on the housing 101 regarding determination of height of the plants cultivated on the green space. The microphone 117 turns the sound energy emitted by the user into electrical energy. The sound waves created by the user carry energy towards the microphone 117. Inside the microphone 117, a diaphragm, made of plastic, is present and moves back and forth when the sound wave hits the diaphragm. The coil attached to the diaphragm also moves in same way. The magnetic field produced by the permanent magnet cuts through the coil. As the coil moves, the electric current flows. The electric current from coil flows to an amplifier which convert the sound into electrical signal. The microcontroller linked to the microphone 117 recognize the voice and perform the operations according to the command given by the user regarding determination of height of the plants cultivated on the green space.

[0028] Upon receiving of the user input, the microcontroller generates a command to activate an artificial intelligence-based imaging unit 103 integrated on the housing 101 for capturing multiple images in a vicinity of the vicinity to the body. The imaging unit 103 incorporates a processor that is encrypted with an artificial intelligence protocol. The artificial intelligence protocol operates by following a set of predefined instructions to process data and perform tasks autonomously. Initially, data is collected and input into a database, which then employs protocol to analyze and interpret the captured images. The processor of the imaging unit 103 via the artificial intelligence protocol processes the captured images and sent the signal to the microcontroller to determine height of the plants cultivated on the green space.

[0029] Based on the detected height, the microcontroller activates a plurality motorized rollers 104 coiled with thermal covers attached with the body to unwrap the covers over the plants. The motorized rollers 104 is integrated with a hub motor in its hub powered by a direct current (DC) motor that rotates the roller for unwrapping the thermal covers.

[0030] Each of the rollers 104 are installed via a pair of L-shaped hydraulic pistons 105 configured to insulate plants and soil areas. The hydraulic pistons 105 are powered by a hydraulic unit that comprises of a hydraulic pump, a hydraulic reservoir, a hydraulic fluid, hydraulic valves, hydraulic cylinders and a hydraulic pump. The hydraulic pump pressurizes the fluid from the reservoir and sends through the hydraulic hose to cylinder. The fluid pressure pushes against the piston, causing it to move. Because the piston is attached to the hydraulic pistons 105, this movement extends the pistons 105 outward from the cylinder. The pistons 105 continue to extend as long as fluid is being pumped into the cylinder.

[0031] When the pistons 105 reach the desired height, the pump stops, and the fluid remain in the cylinder for holding the provide strong, smooth, and accurate motion, ensuring that the insulation is placed precisely where needed and held firmly in place, even in uneven terrain in place. To retract the pistons 105, the hydraulic fluid is directed out of the cylinder and back to the reservoir. This causes the piston to move back into the cylinder, retracting the pistons 105 to provide strong, smooth, and accurate motion, ensuring that the insulation is placed precisely where needed and held firmly in place, even in uneven terrain.

[0032] Each piston bar is equipped with omnidirectional wheel to provide mobility and height adjustment of the motorized thermal covers across the green space. These wheel are made up of a central wheel hub surrounded by multiple smaller rollers 104 placed at an angle (usually 45° or 90°). As a result, when the central wheel turns, the thermal cover allows the piston to glide smoothly in any direction.

[0033] The device is integrated with a plurality of environmental sensors to detect ambient soil and environmental conditions in real-time. The environmental sensors comprise of a temperature sensor, a humidity sensor, a wind sensor and a soil moisture detection sensor.

[0034] The temperature sensor (not shown in figure) measures the heat level in the surrounding environment to monitor how warm or cold the conditions are. In this device, it continuously reads the air temperature near the plants and soil. It usually works using a thermistor or semiconductor element that changes its resistance based on the surrounding temperature. The sensor sends this data to the microcontroller to ensure plants are protected from sudden drops in temperature, especially during frost or cold spells, by triggering appropriate warming actions to maintain a healthy thermal environment.

[0035] The humidity sensor (not shown in figure) measures the amount of moisture in the air around the green space. It typically works using a material that absorbs moisture and changes its electrical properties in response. This change is measured and converted into a humidity reading. In the device, the sensor helps determine how much water vapor is present in the air, which is important for maintaining proper plant health and preventing issues like fungal growth. The readings are processed by the microcontroller to decide whether moisture control measures.

[0036] The wind sensor (not shown in figure), also known as an anemometer, measures the speed and direction of wind in the environment. The sensor includes rotating cups to detect how fast air is moving and from which direction. In this device, the wind sensor helps assess whether it's too windy to safely deploy thermal sheets.

[0037] The soil moisture detection sensor (not shown in figure) measures the amount of water present in the soil. It works by sending an electrical current between two probes inserted into the ground; the conductivity of the soil between them changes depending on how wet or dry it is. Moist soil conducts electricity better than dry soil. The sensor provides continuous data to the microcontroller about whether the soil is too dry, too wet, or within a healthy range, ensuring that plants receive the correct amount of hydration in all conditions.

[0038] The thermal covers are embedded with a plurality of vibration units, activated by the microcontroller to periodically shake off accumulated snow to prevent insulation blockage and structural stress. The vibration unit comprises of an electric motor and an unbalanced weight. The weight is connected to the rotor of the motor. The rotation of the rotor of the motor due to the electric current causes the rotation of the unbalanced weight generating vibrations. The vibration from the vibrating unit is translated to thermal covers to shake off accumulated snow.

[0039] The housing 101 is configured with a storage unit 106 that is divided into several compartments. Each compartment holds thermal sheets that come in different shapes and sizes to suit various plant and soil areas. These thermal sheets are specially designed with materials that regulate temperature as they absorb heat when it's warm and release it when it's cold, helping to maintain a stable environment around the plants.

[0040] If strong wind is detected by the wind sensor, each sheet includes extendable digging pins 118. When the sheets are placed on the ground, these pins extend downward to anchor the sheet securely into the soil, preventing them from being displaced windy or snowy conditions. The extendable digging pins 118 are powered by a pneumatic unit that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the extendable digging pins 118.

[0041] The pneumatic unit is operated by the microcontroller, such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder from one end, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the extendable digging pins 118 and due to applied pressure the digging pins 118 extends and similarly, the microcontroller retracts the extendable digging pins 118 by pushing compressed air via the other end of the cylinder, by opening the corresponding valve resulting in retraction of the piston, and the retraction of the digging pins 118.

[0042] To handle these thermal sheets, the body is installed with a plurality of motorized clamping units 107 via extendable rods 108 to precisely pick up, move, place, and adjust the angle of the thermal sheets to make sure they cover the right areas of soil and plants. The extendable rods 108 are powered by the pneumatic unit associated with the device. The extension/retraction works in the same manner as extendable digging pins 118 described earlier.

[0043] The clamping units 107 are fastening equipment used to grip back portion of the vehicle. Clamping units 107 comprises a pair of curved electromagnetic clamps, which are energized by electromagnets to grip the back portion of the vehicle. The electromagnet consists of wire wound into a coil and a current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. The magnetic field disappears when the current is turned off to release the thermal sheets.

[0044] The rods 108 are installed via motorized ball-and-socket joints 109 to adjust angle to cover plant beds and soil areas, ensuring secure insulation against cold and moisture. The ball-and-socket joints 109 provides a 360-degree rotation to the extendable rods 108 to turn at a desired angle. The ball-and-socket joint 109 is a coupling consisting of a ball joint securely locked within a socket joint, where the ball joint is able to move in a 360-dgree rotation within the socket thus, providing the required rotational motion to the extendable rods 108. The ball-and-socket joint 109 is powered by a DC (direct current) motor that is actuated by the microcontroller thus providing multidirectional movement to the extendable rods 108.

[0045] The temperature sensor constantly monitors the surrounding temperature. Based on the sensor readings, the microcontroller activates a motorized air blower 110 installed on the body via an extendable bar 111. The extendable bar 111 is powered by the pneumatic arrangement associated with the device. The extension/retraction works in the same manner as extendable digging pins 118 described earlier. When activated, the blower emits radiant heat, which is a gentle form of heat similar to sunlight. It targets plant leaves, nearby soil, and the interior parts of the device to help prevent cold damage, especially during freezing weather. The right amount of heat is applied, improving energy efficiency and plant protection. Based on the snow or cold events, the microcontroller regulates actuation of the motorized air blower 110 to provide radiant heat, along with deploying thermal insulation sheets to cover soil and anchor them via the digging pins 118.

[0046] The device also includes a water storage chamber 112 configured with the body and connected to an electronically controlled nozzle conduit 113 to spray warm water directly onto the soil. The nozzle conduit 113 is operated by the microcontroller, which activates it when soil needs moisture or warming. The electronically controlled nozzle conduit 113, used herein, controls flow of water by varying the size of the flow passage as directed by a signal from a microcontroller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, and water level in view of dispensing the water as per the determined requirement of plants.

[0047] A Peltier unit integrated within the chamber 112 to maintain an optimum temperature level of the water stored inside the chamber 112. Peltier unit is based on the Peltier effect that stated that the cooling of one junction and the heating of the other when electric current is maintained in a circuit of material consisting of two dissimilar conductors. The Peltier effect related to production or absorption of heat at the junction of two metals on the passage of a current to maintain an optimum temperature level of the water.

[0048] At the apex side of the water chamber 112, there is a multi-sectioned container 114 that holds salt or other treatment ingredients including minerals or nutrients. This container 114 is connected to the water chamber 112 through a pipe with a motorized valve 115. The microcontroller activates the valve 115 to mix these substances with water in controlled amounts before releasing it through the nozzle.

[0049] Controlled by the microcontroller, the valve 115 remains closed under normal conditions to prevent unintentional mixing. When the microcontroller detects a need for treatment based on real-time soil data, the microcontroller sends a signal to activate the motor attached to the valve 115. The motor then rotates or shifts the valve 115 to an open position, allowing a precise, measured quantity of the selected substance to enter the water chamber 112 through the connected pipe. After the correct amount is dispensed, the valve 115 closes again, ensuring accurate and efficient mixing before the treated water is sprayed onto the soil.

[0050] The device includes a subsurface infrared scanner integrated into the housing 101 to look below the surface of the soil and check the condition of plant roots, especially during cold or winter seasons when roots are more vulnerable to stress or damage. The scanner works by detecting heat patterns and other signals that indicate the presence of abnormalities. The scanner is able to identify root dehydration (lack of water), root rot (due to excess moisture or fungal activity), and freezing damage (caused by extremely low temperatures). When the scanner detects any of these problems, it sends the information to the microcontroller, which then generates an alert. This alert is sent to the computing unit that is accessible to the person responsible for maintaining the green space.

[0051] The communication module facilitates data exchange between computing unit and microcontroller by encoding and sending information over various channels, such as Wireless Fidelity (Wi-Fi), Bluetooth, or cellular networks. The module receives and decodes incoming data from the user's command. The module incorporates error-checking means to detect and correct data corruption or loss and manages data routing to direct information to the microcontroller. The communication module, such as a Wireless Fidelity (Wi-Fi) module connects to the microcontroller to wirelessly transfer data to the computing unit, like a smartphone or server, over a Wi-Fi network. The microcontroller sends the data via the Wi-Fi module to a remote server or cloud service using standard communication protocols (such as HTTP or MQTT). The computing unit then processes the data and sends the alert to the caretaker of the green space.

[0052] In addition, a speaker 116 is integrated into the body of the device is used for outgoing communication, enabling the device to convey information, alerts, or instructions to the nearby caretaker or user. It works in coordination with the microcontroller and sensors to announce real-time updates, such as temperature warnings, successful task completions, or maintenance reminders. The speaker 116 works by converting the electrical signal into the audio signal. The speaker 116 consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, generating a varying magnetic field that interacts with the magnet causing the diaphragm to move back and forth. This movement pushes and pulls air creating sound waves just like the electrical signal received and used to notify the caretaker.

[0053] A battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. 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.

[0054] The present invention works best in the following manner, where the housing 101 as disclosed in the invention is positioned on ground surface in-built with an electrical circuit powering microcontroller, for controlling all linked components. Upon activation, user provides voice command via microphone 117 that converts sound energy into electrical signals, processed by microcontroller to trigger artificial intelligence-based imaging unit 103. This imaging unit 103 captures multiple images, processes them with AI protocol to determine plant height in the green space. Based on plant height, microcontroller activates motorized rollers 104 coiled with thermal covers, unwrapping covers over plants. rollers 104 are mounted via L-shaped hydraulic pistons 105 that extends or retracts pistons 105 precisely to insulate plants and soil. Each piston bar includes omnidirectional wheels 102 allows the smooth mobility and height adjustment of thermal covers. Environmental sensors including temperature, humidity, wind, and soil moisture to continuously monitor conditions, sending data to microcontroller which manages heating via motorized air blower 110 on extendable bar 111 emitting radiant heat to plants and soil. Thermal covers have vibration units activated to shake off snow accumulation. storage unit 106 houses thermal sheets with extendable digging pins 118 for secure anchoring during wind or snow. Motorized clamping units 107 mounted on extendable rods 108 with ball-and-socket joints 109 handle deployment and positioning of sheets. Water storage chamber 112 equipped with Peltier unit maintains water temperature; multi-sectioned container 114 with motorized valve 115 mixes salts or nutrients controlled by microcontroller before spraying treated water through electronically controlled nozzle. Subsurface infrared scanner monitors root health and alerts caretaker via communication module using Wi-Fi or Bluetooth. speaker 116 provides real-time audio alerts by converting electrical signals into sound waves, ensuring efficient green space care.
