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] 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 a modular soil testing device that is capable of optimizing soil testing through analysis, enhancing efficiency, accuracy, and decision-making capabilities, ultimately leading to better project outcomes in construction and agricultural applications.

[0022] Referring to Figure 1, an isometric view of a modular soil testing device is illustrated, comprising a body 101, a multi-sectioned chamber 102 is arranged inside the body 101, a touch interactive display panel 103 arranged on the body 101, a motorized gripper 104 installed inside the body 101 and integrated with a spatula 105, a tray 106 arranged inside the body 101, an artificial intelligence-based imaging unit 107 installed inside the body 101, a multi-sectioned container 108 is arranged inside the body 101, over the tray 106 and integrated with plurality of electronically controlled nozzles 109.

[0023] Figure 1 further illustrates a hydraulic pusher 110 suspended over the tray 106, plurality of extendable pins 111 integrated at sides of the tray 106, a platform 112 arranged inside the body 101, a motorized roller 113 installed on the platform 112, a motorized blade 114 is arranged inside the body 101, plurality of curved members 115 arranged inside the body 101 and integrated with a pair of rolling elements 116, a sieve 117 is arranged inside the body 101.

[0024] The device disclosed herein, comprises of a body 101, which serves as main structure of the device and designed to be placed over a ground surface. The body 101 is constructed from sturdy and robust material which includes, but is not limited to stainless steel, aluminum, and high-grade made plastics like polycarbonate or reinforced nylon. These materials offer strength and rigidity to the body 101 making it resistant to mechanical stress and pressure. The surface of the body 101 is coated with material like Teflon or other low-friction coatings to improve wear resistance and reduce friction.

[0025] The body 101 arranged with a multi-sectioned chamber 102 for storing varying types of soil such as sandy, black and red. The process begins where the user provides input commands over a touch interactive display panel 103 installed on the body 101 about parameters for testing the soils. 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. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding the parameters to be tested on the soils. A touch controller is typically connected to a microcontroller through various interfaces which may include but are not limited to PI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0026] The display panel 103 sends these inputs to the microcontroller for further processing. After receiving these commands, the microcontroller process these commands and accordingly actuates a motorized gripper 104 arranged within the housing and having a spatula 105 as its end effector, to grasp a portion of a particular soil from the chamber 102 and dispense it over a tray 106 arranged within the body 101. The gripper 104 is a type of mechanical arm which is usually available with similar function to a human arm.

[0027] The segments of such a manipulator are connected by joints allowing either rotational motion or translational displacement. The gripper 104 contains several segments that are attached together by joints also referred to as axes. The gripper 104 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 gripper 104 to complete a specific motion in translating the equipped spatula 105 for gripping the soil from the chamber 102 and releasing it over the tray 106 in precise manner.

[0028] After dispensing the soil on the tray 106, the microcontroller actuates an artificial intelligence-based imaging unit 107 arranged within the housing to capture multiple high-resolution images inside surrounding of the body 101 for monitoring spreading of the soil on the tray 106. The artificial intelligence based imaging unit 107 is constructed with a camera lens and a processor, wherein the camera lens is adapted to capture a series of images of the surrounding present inside the body 101.

[0029] The processor carries out a sequence of image processing operations including pre-processing, feature extraction, and classification. The image captured by the imaging unit 107 is real-time images of the body 101’s inner surrounding. The artificial intelligence based imaging unit 107 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 positioning of the soil spread on the tray 106.

[0030] A multi-sectioned container 108 attached at side wall of the body 101 and configured with multiple electronically controlled nozzles 109. As the microcontroller detects the exact positioning, the microcontroller actuates the nozzles 109 to dispense water stored in the container 108, over the spread soil for adding moisture in the soil at optimal rate. The electronic nozzle 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.

[0031] Upon actuation of nozzle by the microcontroller, the electric motor or the pump pressurizes the incoming water, increasing its pressure significantly. High pressure enables the water to be sprayed out with a high force, thereby dispensing the water over the soil at optimal rate. During the nozzle dispensing water on the soil, the microcontroller actuates an ultrasonic sensor installed within the body 101 to detect thickness of the soil. The ultrasonic sensor emits high-frequency waves toward the soil and measures the time it takes for the waves to bounce back after hitting the surface of the soil.

[0032] The ultrasonic sensor is typically oriented in a way that it measures the thickness of the soil. The ultrasonic sensor collects a significant amount of data by scanning the entire surface of the soil and forms a 3D point cloud, which represents the shape of the soil. The ultrasonic sensor sends the data to a microcontroller which processes the acquired data and detects the thickness of the soil. The acquired data is sent to the microcontroller which processes the information and actuates the gripper 104 to dispense another layer of the soil over the wet soil by gripping the soil from the chamber 102.

[0033] After layering another layer of the soil, a non-contact moisture sensor installed inside the body 101 get actuated by the microcontroller to monitor moisture content in the second layer due to first layer’s moisture content. The non-contact moisture sensors typically rely on electromagnetic or capacitive methods to detect moisture. The key idea is that moisture affects the dielectric properties of a material, which is measured without direct contact.

[0034] These sensors measure the change in capacitance between two layers of the soil. The dielectric constant of the material changes with moisture content. Since water has a high dielectric constant compared to dry materials, the capacitance changes as moisture levels vary. The sensor uses this change in capacitance to estimate the moisture content of the second layer for testing water retention property of the soil.

[0035] A timer inbuilt in the microcontroller to detect time period for helping in evaluation of the water retention property of the soil. After testing the water retention property of the soil, the microcontroller actuates another nozzle to dispense a chemical, like terrenoseal stored in the chamber 102, on the soil. Simultaneously, the microcontroller actuates a hydraulic pusher 110 installed over the celling portion to get extend and provide thumping movement over the tray 106 for compacting the soil.

[0036] The hydraulic pusher 110 linked with a hydraulic unit which comprises an oil compressor, cylinders, oil valves and piston that works in collaboration for extension/retraction of the pusher 110. The oil compressor pressurizes hydraulic fluid to provide the necessary force for the hydraulic unit to operate. The hydraulic cylinders convert the pressurized hydraulic fluid’s energy into linear motion. As the fluid enters the cylinder, it pushes against a piston inside, causing the pusher 110 connected to the piston to extend/retract. Oil valves regulate the flow of hydraulic fluid within the hydraulic unit and controls the extension/retraction of the pusher 110.

[0037] The piston located inside the hydraulic cylinder is directly linked to the pusher 110. When the pressurized fluid enters the cylinder, it pushes the piston, causing the connected pusher 110 to extend and thumping over the tray 106, which results in compacting the soil, wherein the tray 106 configured with multiple extendable pins 111 that are actuated by the microcontroller to get extend in such manner that it gets penetrate in the soil, which results in creating holes in the soul. The extension of pins 111 as mentioned herein are powered by a pneumatic unit that utilizes compressed air to extend and retract the pins 111.

[0038] 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 pins 111. The piston is attached to the pins 111 and its movement is controlled by the flow of compressed air. To extend the pins 111 the piston activates the air valve to allow compressed air to flow into the chamber behind the piston. As the pressure increases in the chamber, the piston pushes the pins 111 to the desired length for penetrating the pins 111 in the soil. The nozzle dispense water simultaneously in the holes for determining dissolution of the holes to analyze porosity of the soil.

[0039] The microcontroller actuates the gripper 104 to dispense another portion of the soil over a platform 112 installed inside the body 101 by means of the spatula 105. Next, the microcontroller actuates the nozzle to dispense water over the platform 112 at a regulated rate. After dispensing the water, the microcontroller actuates a motorized roller 113 mounted on the platform 112 to get rotate over the soil for kneading the soil. The motorized roller 113 is a mechanical unit designed to rotate on its axis with the help of an integrated electric motor. The cylindrical roller 113 tube serves as a surface for supporting, and kneading the soil.

[0040] The motorized roller 113 is equipped with an electric motor that provides the rotational power necessary to turn the roller 113. The motor is connected to the roller 113 tube through a drive mechanism, which involves gears, belts to transfer the motor’s rotational force to the roller 113, causing it to spin and knead the soil. After kneading the soil, the microcontroller actuates a motorized blade 114 arranged within the body 101 to cut the kneaded soil into multiple parts. The motorized blade 114 is equipped with a sharp cutting tool, such as a blade 114 or a rotary cutter, which is driven by an electric motor.

[0041] The motorized blade 114 is positioned at the end-effector of a robotic link. The robotic link is equipped with multiple joints and actuators that allows the robotic link to move in multiple dimensions and orient the motorized blade 114 with great precision. Once the robotic link positions the motorized blade 114 in close proximity to the kneaded soil, the microcontroller actuates the motor inside the motorized blade 114 to rotate which in turn drives the motorized blade 114. The blade 114 makes a precise and controlled cut, creating multiple partitions.

[0042] The device features multiple curved members 115, which are positioned inside the body 101. These curved members 115 are specifically designed to interact with the kneaded soil, playing a crucial role in assessing the soil's properties. The curved members 115 are integrated with a pair of rolling elements 116 to get rotate and apply controlled pressure on the soil. When the curved members 115 are positioned over the kneaded soil, the rolling elements 116 are actuated to rotate, applying gentle yet firm pressure on the soil. This controlled pressure enables the microcontroller to monitor the adherence of the soil particles, providing valuable insights into the soil's composition and properties. The data collected during this process is stored in a database linked with the microcontroller, allowing for efficient data management and analysis.

[0043] A sieve 117 positioned inside the main body 101 for evaluating the purity of the soil by filtering out debris and other impurities. The sieve 117 ensures that it effectively separates the soil particles from unwanted contaminants, providing an accurate assessment of the soil's composition. The sieve 117 is accessed by the gripper 104, which carefully maneuvers the soil into the sieve 117 for filtering. As the soil passes through the sieve 117, debris and other impurities are separated from the soil particles, allowing for a precise determination of the soil's purity. This process is essential in understanding the soil's properties and characteristics, enabling informed decisions to be made regarding its use and management.

[0044] A heating unit arranged with the tray 106 for providing heat to the wet and dry state of the soil. The heating unit used herein is preferably a copper coil that generates heat when an electric current passes through the coil. When an electric current runs through a copper wire the electrons come across the resistive forces of the medium’s material, releasing energy that is expended in the form of heat energy. The copper coil is properly insulated to prevent any heat loss and also direct the generated heat toward the soil. The heating unit begins to generate heat and as the heating element warms up, the tray 106 heats the wet or dry state.

[0045] After heating the heating wet or dry state of the soil, the microcontroller actuates a pressure sensor embedded with the spatula 105 for monitoring plasticity of the soil. The pressure sensor contains a piezoelectric material, which generates a voltage in response to mechanical stress. When a pressure is applied by the spatula 105 on the soil, it deforms the piezoelectric material. The pressure applied by the spatula 105 on the soil causes the material to deform, creating a strain. This strain results in the generation of an electric charge across the material, producing a voltage signal proportional to the applied pressure. The generated voltage is typically very small so the signal is amplified to make it suitable for further processing.

[0046] Lastly, all evaluated data for tested parameters on the soil is stored in a database linked with the microcontroller and processed by the microcontroller to determine a construction work to be performed with the soil.

[0047] The present invention works best in following manner, where the body 101 as disclosed in the invention is developed to be positioned over the ground surface, the process begins with the user placing different kinds of soil in the multi-sectioned chamber 102 inside the body 101. The user then accesses the touch interactive display panel 103 to provide input regarding the parameters to be tested on the soils. This input is then processed by the inbuilt microcontroller, which actuates the motorized gripper 104 to grab and dispense a portion of the selected soil evenly on a tray 106 inside the body 101. The artificial intelligence-based imaging unit 107 captures and processes multiple images of the soil spread on the tray 106 to determine its positioning. The microcontroller then actuates the electronically controlled nozzles 109 to dispense water over the spread soil at a regulated rate. The ultrasonic sensor monitors the thickness of the soil while it's being wet. The non-contact moisture sensor monitors the moisture content transfer to the upper layer of soil from the lower layer, and the timer integrated with the microcontroller monitors the time period for evaluating the water retention property of the soil. Post-testing the water retention property, the microcontroller actuates another nozzle to dispense a chemical (preferably Terrenoseal) over the soil. The hydraulic pusher 110 then performs a thumping movement over the tray 106 to compact the soil. The extendable pins 111 are then actuated by the microcontroller to penetrate the soil and pierce holes. Water is then dispensed into the holes to evaluate the porosity of the soil by monitoring the dissolution of the holes. The microcontroller then directs the gripper 104 to dispense another portion of soil onto a platform 112. An optimum amount of water is then dispensed, and the motorized roller 113 kneads the soil. The motorized blade 114 then cuts the kneaded soil into partitions. The curved members 115 are then positioned over the kneaded soil, and the rolling elements 116 rotate to apply pressure. The adherence of the soil particles is monitored, and the data is stored in a database linked with the microcontroller. Optionally, a sieve 117 to filter a portion of the soil and determine debris present in the soil, thereby evaluating its purity. Additionally, a heating unit integrated on the tray 106 can be actuated by the microcontroller to heat the wet and dry state of the soil. A pressure sensor integrated on the spatula 105 monitors the plasticity of the soil. Finally, all evaluated data for tested parameters on the soil is stored in the database, processed by the microcontroller, and used to determine the construction work to be performed with the soil.
