BACKGROUND OF THE INVENTION

[0002] Maintaining green landscapes in urban spaces is essential for ensuring environmental sustainability, aesthetic appeal, and the overall well-being of the community. Urban green spaces, including parks, gardens, and other green areas, play a vital role in improving air quality, reducing urban heat islands, enhancing biodiversity, and providing recreational spaces for people. However, these spaces require regular maintenance to remain healthy and functional. This includes tasks such as soil care, irrigation, fertilization, pest control, and the repair of infrastructure. Proper soil management, including monitoring moisture levels, pH, and nutrient content, is crucial to support healthy plant growth and prevent degradation. Additionally, frequent inspections and repairs are necessary for outdoor furniture, pathways, and other amenities that may suffer from wear and tear or environmental damage. With the growing urban population and increased pressure on these spaces, the need for effective maintenance solutions has never been more critical. Traditional manual methods of maintaining these spaces can be labor-intensive and inefficient. Therefore, the integration of automated systems and technology in landscape maintenance, such as AI-powered surveillance, sensors for soil health monitoring, and automated fertilization systems, can enhance the precision, efficiency, and sustainability of urban green space upkeep. This approach ensures that these valuable areas remain safe, vibrant, and accessible to the public.

[0003] Various equipment and tools are used for the maintenance of green landscapes, ensuring they remain healthy, aesthetically pleasing, and functional. Common equipment includes lawnmowers, hedge trimmers, leaf blowers, irrigation systems, fertilizing machines, and soil testing kits. Lawn mowers and trimmers help in keeping grass and shrubs neatly trimmed, while leaf blower’s clear debris, improving the appearance and safety of the space. Automated irrigation systems ensure consistent watering, and fertilizing machines distribute nutrients efficiently. Soil testing kits and sensors monitor moisture levels, pH, and nutrient content, aiding in proper soil management. However, traditional landscape maintenance equipment often comes with several drawbacks. Manual tools are labor-intensive and time-consuming, requiring significant human effort for tasks such as trimming, weeding, and fertilizing. Mechanical equipment, such as mowers and blowers, can be noisy and may disturb the peace of public spaces. Moreover, many devices rely on fossil fuels, contributing to air pollution and carbon emissions. Additionally, irrigation systems can lead to water wastage if not properly managed, especially in areas where water scarcity is a concern. Equipment for fertilization and pest control may not always be precise, leading to overuse of chemicals that could harm the environment. As a result, more sustainable and automated maintenance solutions are being explored to overcome these limitations.

[0025] The present invention includes a body 101 preferably in portable nature incorporating various components associated with the device, developed to be positioned on an urban green space surface. The bottom portion of the body 101 is configured with multiple motorized wheels 102 for enabling movement of the body 101 across the surface.

[0026] A user is required to access and presses a push button arranged on the body 101 to activate the device for associated processes of the device. 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.

[0027] The bottom portion of the body 101 is integrated with L-shaped link 103. A pneumatic pin 104 is attached with the link 103 as an end effector. A pneumatic arrangement is associated with the device for providing extension/retraction of the link 103 as per requirement. The pin 104 is mounted with multiple environmental sensing units. For assessing health condition so of the soil and plants, the sensing units are required to be positioned underneath the soil via the pin.

[0028] The microcontroller actuates an air compressor and air valve associated with the pneumatic arrangement consisting of an air cylinder, air valve and piston which works in collaboration to aid in extension and retraction of the pin. The air valve allows entry/exit of compressed air from the compressor. Then, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the pin 104 and due to the increase in the air pressure, the piston extends. For the retraction of the piston, air is released from the cylinder to the air compressor via the valve. Thus, providing the required extension/retraction of the pin 104 for orienting the sensing units within the soil of the urban green space area. All the pneumatically operated components associated with the device comprises of the same type of pneumatic arrangement.

[0029] The environmental sensing units integrated into the pin 104 continuously monitoring the various factors affecting the health and sustainability of the urban green space. These sensors include, but are not limited to, a soil moisture sensor, which detects the water content within the soil to ensure optimal irrigation; a soil color sensor, which helps determine the health of the soil by detecting changes in its color, often indicative of nutrient imbalances or soil degradation.

[0030] Additionally, the environmental sensing units incorporate an NPK sensor to measure the levels of Nitrogen, Phosphorus, and Potassium essential nutrients for plant growth enabling precise nutrient management. A soil pH sensor assesses the acidity or alkalinity of the soil, ensuring it remains within the ideal range for plant health. A temperature sensor monitors environmental temperature, providing data for better decision-making in terms of irrigation and fertilization. And, a laser sensor aids in measuring distances or detecting obstacles, ensuring the body 101 navigate efficiently and perform its functions without interference.

[0031] The microcontroller assesses the collected data of the sensing units to determine health parameters of the soil plant vitality, and the overall integrity of the green space. Based upon the soil condition, the microcontroller evaluates a suitable fertilizer for the soil. The body 101 is equipped with a multi-sectioned chamber 201 storing multiple type of fertilizers in the sections of the chamber 201. The fertilizers are stored in a medicinal solution. Each of the section of the chamber 201 is connected with an electronically controlled spout 105.

[0032] Based upon the requirement of specific type of fertilizer, the microcontroller actuates the spout 105 of respective section of the chamber 201 for dispensing the required fertilizer in the soil. Each of the spout 105, used herein, is a short tube with a taper integrated with fine-tuned valve or orifice that is electronically regulated to speed up or regulate the flow of the medicinal solution of fertilizer. The valve controls flow of the medicinal solution by varying the size of the flow passage 207 as directed by a signal from the microcontroller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, and the medicinal solution level in view of dispensing the medicinal solution as per the determined requirement, in order to increase fertility of the soil for proper nourishment.

[0033] In addition, the device features to identify unauthorized activities in the urban green space. The microcontroller generates a command to activate an artificial intelligence-based imaging unit 106 integrated on the body 101 for capturing multiple images in a vicinity of the body 101 for continuous surveillance of the urban green space to detect and identify unauthorized activities. The imaging unit 106 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 106 via the artificial intelligence protocol processes the captured images and sent the signal to the microcontroller.

[0034] In case the microcontroller evaluates any unauthorized activity undergoing in the urban green space, the microcontroller activates a speaker 107 installed in the body 101 to alert the user regarding the detected unauthorized activity. The speaker 107 works by taking the input signal from the microcontroller, it then processes and amplifies the received signal through a series of equipment in a specific order within the speaker 107, and then sends the output signal in form of audio notification through the speaker 107 for alerting the user regarding the detected unauthorized activity within the urban spaces.

[0035] In addition, the microcontroller activates a display panel 108 installed on the body 101. The display panel 108 works by receiving real-time data from various sensors and the AI-powered imaging unit 106, which monitor the urban green space for any detected activities or changes. Once the microcontroller identifies an event, such as unauthorized entry or environmental issues, the microcontroller processes this information and generates a corresponding visual alert. The alert is then transmitted to the display panel 108, which updates its screen accordingly. The display shows the alert in the form of text, icons, or color-coded symbols, allowing the user to quickly assess the situation. The panel also provide further details or options for user interaction, such as acknowledging the alert or triggering additional actions like deploying barriers or activating other safety procedures. This ensures timely and intuitive notifications, allowing for effective management of the green space.

[0036] The body 101 is arranged with a box 109. A U-shaped frame 110 is integrated with the box 109. The frame 110 incorporates a plurality of telescopic rods 111 via multiple hinges 112. The extension/retraction of the rods 111 is powered by the pneumatic arrangement. The ends of the rods 111 are securely hooked with a stretchable fabric. The working of the extension/retraction of the rods 111 is similar to the working of the pin 104 as mentioned above. The microcontroller actuates the rods 111 via the pneumatic arrangement, for engaging the stretchable fabric over furniture(s) pre-installed on the urban green space to form a protective shield.

[0037] Synchronously, the microcontroller actuates the hinges 112, in sync with the imaging unit 106 for stretching the fabric over the furniture. The microcontroller actuates a direct current (DC) motor associated with the hinges 112 such that tilt the rods 111 by revolving along the longitudinal axis. The tilting of the rods 111 ensures secured deploying of the fabric over the furniture, preventing exposure of the furniture(s) to direct sunlight and avoiding damage such as discoloration or material degradation.

[0038] The microcontroller via the imaging unit 106 detects faded or missing color on pavement of the urban green space. The body 101 is integrated with multiple containers 202 filled with a different colored marking fluid provided along a bottom periphery of the body 101. A horizontal roller 113 mounted adjacent to the containers 202 and equipped with a brush 114. The roller 113 is connected with the containers 202 by means of plurality of electronic valves 115. Based upon the detected faded or missing color on pavement, the microcontroller accordingly actuates specific valve 115 associated with the container storing similar color, for dispensing color over the pavement. The working of the valves 115 is similar to the working of the spout 105 s as mentioned above, to dispense suitable color to the brush 114 of the roller 113.

[0039] The roller 113 is connected with the body 101 by means of telescopic poles. The extension/retraction of the shafts are powered by the pneumatic arrangement. The working of the extension/retraction of the shafts are similar to the working of the pin 104 as mentioned above. The microcontroller actuates the shafts via the pneumatic arrangement to position the roller 113 in contact with the surface of the pavement for the application of the paint over the pavement.

[0040] Synchronously, the microcontroller then actuates a direct current (DC) motor associated with the roller 113 such that rotates an integrated hub of the roller 113. The rotation of the hub of the roller 113 consequently results in rotation of the roller 113 for applying the fluid color over the pavement via the rotation of the brush 114. The microcontroller regulates the actuation of the valves 115 for dispensing of the color to ensure efficient painting operation over the pavement.

[0041] In accordance to the regulation of paint application, the microcontroller then powers an associated direct current (DC) motor connected with the wheels 102. The wheels 102 have small discs or rollers around the circumference of the wheel that are powered by the motor, enabling the wheels 102 to move in required direction, which provide the body 101 with the required movement for maneuvering over the surface, to apply paint over the required region of the pavement.

[0042] The microcontroller via the imaging unit 106 detects a restricted or recently repaired urban green space zone. The restricted or repaired region over the urban green space is required to be protected by barricading. The body 101 is configured with a storage unit 203 positioned within the body 101. The storage unit 203 is stored with multiple safety barriers in the form of vertical poles with sharp pointed ends.

[0043] The periphery of the storage unit 203 is integrated with a motorized horizontal slider 204. An L-shaped telescopic bar 205 is mounted on the slider 204. A three-point gripper 206 is integrated at the end of the bar 205 as an end effector by means of a ball and socket joint. The extension/retraction of the bar 205 is powered by the pneumatic arrangement. The working of the extension/retraction of the bar 205 is similar to the working of the pin 104 as mentioned above. In relation to form the barricading over the restricted region of the urban green space, the microcontroller actuates the bar 205 via the pneumatic arrangement to extend and grip the barriers from the storage unit 203.

[0044] Synchronously, the microcontroller actuates the gripper 206 for gripping the barrier from the storage unit 203. The gripper 206 comprises an electric motor and linked with the microcontroller. The microcontroller provides a signal relating to the force, position, or the speed required of the gripping. The gripper 206 receives the signal and its motor carries out the gripping of the barrier from the storage unit 203. The ball and socket joint provides multi-directional movement to the gripper 206 as per requirement, for individually gripping the stored barriers.

[0045] The body 101 is configured with a vertical passage 207 defined on a vertical side of the body 101. The passage 207 is integrated with a motorized vertical sliding unit 208 along inner periphery. A C-shaped clipper 209 is mounted on the sliding unit 208. Post gripping of the barriers by the gripper 206, the microcontroller actuates the slider 204 to position the gripped barriers over the passage 207.

[0046] Simultaneously, the microcontroller actuates the sliding unit 208 to position the clipper 209 at top portion of the passage 207 for receiving the barriers form the storage unit 203. The working of the sliding unit 208 is similar to the working of the slider 204 as mentioned above. The microcontroller accordingly actuates the clipper 209 in sync with the imaging unit 106 to grip and securely hold the barrier positioned over the passage 207 by the gripper 206. The working of the griper and the clipper 209 is same as mentioned above.

[0047] Post gripping of the barrier into the passage 207, the microcontroller then actuates the sliding unit 208 to position the clipper 209 to dispense the barriers toward a target ground area via the passage 207. The microcontroller directs the gripper 206 to sequentially extract the barriers from the chamber 201 and insert them into the vertical passage 207.

[0048] Additionally, the microcontroller via the imaging unit 106 detects a person attempting to forcibly enter the urban green space by jumping over door of the urban green space. The body 101 is arranged with a pair of motorized vertical sliders 116. A vertically movable barrier plate 117 is configured with the vertical sliders 116. The working of the vertical sliders 116 is similar to the working of the horizontal slider 204 as mentioned above.

[0049] In order to prohibit the entrance of the person into the green space, the microcontroller actuates the wheels 102 to position the body 101 in proximity to the door. The microcontroller synchronously, actuates the vertical sliders 116 for extending the vertically movable barrier plate 117 at a height in proximity to the door. The extension of the plate 117 incurs a heighted barrier over the door, making an absolute prevention of the person to attempt entry into the space. The elevated vertical plate 117 causes obstruction for the unauthorized entry.

[0050] Additionally, the microcontroller via an inductive proximity sensor embedded in the body 101, detects presence of rusted portion in the urban green space infrastructure. The proximity sensor emits infrared rays towards the infrastructure and receives the bounced back rays from the infrastructure and convert the detected data into an electric signal that is sent to the microcontroller. The microcontroller processes the received signal from the proximity sensor in order to monitor distance of rusted portion in the urban green space infrastructure.

[0051] The body 101 is configured with a vessel 210 stored with a metal primer composition. An electronic sprinkler 118 is connected with the vessel 210. Based upon detection of the presence of rusted portion in the infrastructure, the microcontroller actuates the wheels 102 to position the body 101 in proximity to the detected region of the infrastructure.

[0052] Post positioning of the body 101, the microcontroller actuates the sprinkler 118 to dispense the metal primer composition over the rusted portion of the infrastructure. The working of the sprinkler 118 is similar to the working of the spout 105 as mentioned above.

[0053] During the ongoing operation of maintenance and repairing of the urban green space, the visitors or workers are kept informed about the ongoing work via a holographic projection unit 119 is installed on the body 101. The holographic projection unit 119 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 119 projects light onto a surface from multiple angles, using the interference of light waves to produce 3D images visible from different perspectives. The projected visual alerts or provide instructions in vicinity of the body 101 for informing visitors or workers about ongoing operations or detected hazards.

[0054] In addition, during the maneuvering of the body 101 within the urban green space, the microcontroller via a crack detection sensor integrated with the body 101 physical damage on urban green space structures, in sync with the imaging unit 106. The crack detection sensor is an ultrasonic based crack detection sensor, disclosed herein, consists of an emitter and a receiver that acts as a transducer. On activation of ultrasonic sensor by the microcontroller, the emitter emits ultrasonic sound waves towards the lens. Further, the radiation strike to the lens and reflect back which are captured by the receiver. The signal is sent to the microcontroller. The microcontroller processes the received signal from the ultrasonic based crack detection sensor and on the basis of time lapse in between the sent and received radiations, the microcontroller determines the presence of any crack over the structures of the urban green space.

[0055] Based upon detection of any crack or structural anomaly the microcontroller transmits an alert signal to computing unit of concerned authorities via a communication module to notify concerned urban green space authorities for initiating required repair actions. 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. 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 for communication of wireless commands to inform concerned authorities to initiate repair operation of the detected crack or structural anomaly, thereby ensuring safety and structural integrity.

[0056] 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.

The L-shaped link 103 with the pneumatic pin 104 penetrates the soil to assess health and the condition of soil and plants of the urban space. The microcontroller analyzes soil conditions and dispenses suitable fertilizers or medicinal solutions via the electronically controlled spout 105. The AI-powered imaging unit 106 continuously monitors the space for unauthorized activities, triggering audio-visual alerts through the inbuilt speaker 107 and display panel 108. The body 101 deploy the protective fabric over outdoor furniture using telescopic rods 111, protecting the furniture from sunlight damage. The body 101 marks faded pavement areas by dispensing colored fluid from containers 202 onto the roller 113 with the brush 114. Additionally, the body 101 stores safety barriers, deploys them using the motorized slider 204, and adjusts the height of urban green space doors to prevent unauthorized entry.
