[0024] Referring to Figure 1, an isometric view of an autonomous site of interest investigation device is illustrated, comprising of a base platform 101 having a motorized track wheel 102 installed at each corner via a two-bar linkage unit 103, an AI (artificial intelligence)-enabled camera 104 mounted on the platform 101, a collapsible barricading structure mounted on one side of the platform 101, the collapsible barricading structure comprises of a pair of motorized cam-and-slider unit 105 provide on the side of the body, a collapsible scissor unit 106 integrated between the cam and slider unit 105, a zig-zag patterned sheet 107 incorporated with the collapsible scissor unit 106, a marking module integrated with the platform 101, the marking module marking module comprises of marker tool 108 attached to a rectangular frame 109 with a multi-axis slider 110 and an articulated link 111, a plurality of pneumatic probes 112 provided with the platform 101.

[0025] Figure 1 further includes a sample collection module integrated with the platform 101, the sample collection module includes a parallelogram linkage unit 113 provided on the platform 101 and integrated with a motorized gripping unit 114, a sterile container 115 integrated with the platform 101, a first articulated arm 116 with a V-shaped plate 117 mounted on the platform 101, an adhesive dispensing arrangement integrated with the platform 101, the adhesive dispensing arrangement includes a roller 118 mounted on a free-end of an robotic link 119 provided on the platform 101, a plurality of micro holes 120 distributed on surface of the roller 118, a plurality of pusher plate 121 integrated with the roller 118, an automated sprayer 122 mounted on a second articulated arm 123, a deterrent module comprising ultrasonic emitters 124 and low-intensity light flashers 125 are integrated on the platform 101, an audio module comprising a speaker 126 and a microphone 127 integrated with the platform 101, and a display unit 128 mounted on the platform 101, and a high-intensity LED light 129 integrated with the platform 101.

[0026] The device disclosed herein comprises of a base platform 101 having a motorized track wheel 102 mounted at each corner through a two-bar linkage unit 103. A user is required to manual switch on the device by pressing the button positioned on the device. After switching on the device by the user, an inbuilt microcontroller generates a command to actuate the motorized track wheel 102 functions by converting electrical energy supplied to the motor into rotational torque, which is transferred to the wheel 102 for ground engagement.

[0027] The track encircles the wheel 102 and establishes frictional contact with the terrain, thereby facilitating traction and controlled propulsion. During operation, the wheel 102 maintains synchronized motion with its counterparts, enabling precise navigation across the designated site. The speed and direction are regulated through motor input commands, ensuring adaptability over varying surface conditions. The wheels 102 ensure forward, reverse, and turning motions are executed with accuracy, maintaining load-bearing stability throughout the platform’s deployment and site mobility.

[0028] The two-bar linkage unit 103 herein functions for enabling controlled articulation by transmitting motion through pivot joints that convert motor-driven rotation into stabilized wheel 102 displacement. The linkage unit 103 maintains geometric alignment, thereby reducing undue stress on both the platform 101 and wheel 102 during movement. As the wheel 102 encounters terrain irregularities, the linkage unit 103 adapts dynamically, ensuring sustained ground contact while mitigating vibrations. The two-bar linkage unit 103 ensures smooth vertical and angular adjustments without compromising directional precision, thereby ensuring seamless integration of mobility, stability, and maneuverability.

[0029] An inspection unit is mounted on the platform 101 through a motorized rotary joint and configured to perform continuous 360-degree monitoring and analytical assessment of the surrounding environment. The inspection unit integrates an artificial intelligence-enabled camera 104, infrared thermal sensor, LiDAR sensor, hyperspectral sensor, and volatile organic compound (VOC) sensor, wherein each sensor captures multi-dimensional datasets corresponding to visual, thermal, spatial, spectral, and chemical attributes of the monitored site. The aggregated data is processed by the AI-enabled camera 104 for identifying, classifying, and recording objects, patterns, anomalies, and trace sample in real-time, thereby enabling precise detection and analytical determination of site-specific findings.

[0030] The inspection unit transmits captured data in its respective domain visual, thermal, spatial, spectral, and chemical. The inspection unit integrates and synchronizes the incoming data into a unified processing module, where artificial intelligence protocols analyze cross-referenced datasets to detect, classify, and record anomalies, objects, wound patterns, and traces. The motorized rotary joint functions by mechanically coupling the inspection unit to the platform 101 while providing rotational movement across a controlled axis. A motor drives the joint, enabling precise angular rotation to achieve 360-degree field coverage.

[0031] The AI-enabled camera 104 herein operates by capturing high-resolution visual imagery in real time and transmitting the data to an onboard processor. As each frame is captured, the AI compares visual inputs against stored models to identify and classify objects, traces, or patterns. The AI camera 104 further performs adaptive learning by updating its models with new findings, thereby improving detection accuracy and ensuring continuous monitoring aligned with site-specific requirements. The infrared thermal sensor functions by detecting infrared radiation naturally emitted from objects, surfaces, and human or animal bodies. The sensor converts infrared wavelengths into electrical signals, which are processed to generate a thermal image representing temperature variations across the scanned area.

[0032] During operation, thermal gradients are continuously mapped, enabling detection of heat signatures, surface anomalies, wound patterns, or concealed traces. The sensor synchronizes with the inspection unit’s rotation, allowing overlapping scans for complete thermal mapping. The temperature data is further analyzed by the AI camera 104 for classification, comparison, and anomaly detection, thereby enhancing environmental assessment and examination. The LiDAR sensor mentioned herein operates by emitting pulsed laser beams towards surrounding surfaces and measuring the time delay of reflected signals to calculate precise distances.

[0033] The measurements are continuously recorded across multiple angles during inspection unit rotation, producing a dense point cloud that forms a three-dimensional representation of the environment. The sensor identifies structural features, object outlines, and spatial anomalies with centimeter-level accuracy. The hyperspectral sensor herein functions by capturing reflected electromagnetic radiation across a wide spectrum of contiguous wavelength bands, exceeding standard RGB capabilities.

[0034] During operation, the sensor records spectral signatures of surfaces, objects, and materials at each scanned pixel. These spectral datasets are analyzed to differentiate subtle material variations, detect biological or chemical residues, and identify traces otherwise undetectable by conventional imaging. As the inspection unit rotates, the hyperspectral sensor continuously records overlapping scans, ensuring seamless spectral coverage. The volatile organic compound (VOC) sensor mentioned above operates by drawing in air samples from the surrounding environment and exposing them to a sensitive detection chamber, which reacts to specific organic compounds.

[0035] The sensor converts chemical interactions into measurable electrical signals, producing concentration values for identified VOCs. During continuous monitoring, the sensor detects presence, type, and level of gaseous compounds emitted from surfaces, traces, or chemical residues. The collected data is synchronized with visual, thermal, spatial, and spectral streams. AI processor analyzes the readings to identify hazardous substances, classify site sampling, and issue alerts when concentrations exceed predefined threshold values. A collapsible barricading structure is installed on one side of the platform 101 and designed to provide a secure, extendable perimeter around a designated site.

[0036] In operation, the structure deployed and retracted efficiently, allowing controlled access and enhanced safety. When activated, the structure extends outward to form a continuous physical barrier, and upon deactivation, it collapses into a compact form for storage. The collapsible barricading structure including of a pair of motorized cam-and- slider unit 105 provide on the side of the body, a collapsible scissor unit 106 integrated between the cam and slider units 105, a collapsible scissor unit 106 integrated between the cam and slider units 105, and a zig-zag patterned sheet 107 incorporated with the collapsible scissor unit 106.

[0037] The deployment is synchronized with the motorized cam-and- slider units 105 and collapsible scissor unit 106 to ensure smooth extension without manual intervention. The structure maintains rigidity during use and returns to a stowed position safely, providing a repeatable and controlled means of securing a site. The pair of motorized cam-and- slider units 105 converts rotational motor input into linear motion, propelling the scissor unit 106 outward or inward. The cams engage with slider unit 105 to control the precise extension rate, maintaining stability and preventing abrupt movement. The synchronized operation of both units ensures balanced deployment along the platform 101 edge. The collapsible scissor unit 106 herein serves as the expandable framework of the barricade.

[0038] During operation, the scissor arms pivot at their joints, allowing the structure to extend into a rigid, rectangular barrier. As the motorized cam-and- slider units 105 advance, the scissor links unfold sequentially, controlling the height and width of the deployed barricade. The geometry of scissor unit 106 ensures smooth motion without jamming and provides uniform load distribution across the structure, thereby enabling rapid deployment and stowing, creating a reliable physical barrier. The zig-zag patterned sheet 107 mentioned above functions for forming the visible barrier surface.

[0039] During deployment, as the scissor unit 106 expands, the sheet 107 unfolds in coordination, maintaining a continuous rectangular coverage. The sheet 107 is imprinted with warning messages to alert unauthorized personnel and enhance visibility. The material and configuration of the sheet 107 provide both flexibility for movement and durability to withstand repeated extension and collapse. The sheet’s integration ensures the barricade functions as a cohesive security unit while conveying clear safety instructions. A marking module is incorporated within the platform 101 to enable precise demarcation of sites of interest based on imaging data.

[0040] The module aligns a marker tool 108 attached to a rectangular frame 109 with the predetermined outline, moving to trace boundaries as defined by the data. The microcontroller ensures consistent visibility and accuracy of the markings while compensating for positional shifts or distortions. The module operates in real time, producing reproducible and legally defensible outlines for documentation or procedural purposes within the platform 101 environment. The marker tool 108 herein functions as the operative interface for delineating outlines. Upon engagement, the tool 108 receives directional input from the microcontroller and applies marking material or visual indicators along the target site.

[0041] The rectangular frame 109 provides structural stability, maintaining consistent orientation and pressure during operation. The frame 109 guides the marker with a multi-axis slider 110 and an articulated link 111 along straight and curved paths while preventing lateral deviation. The movements of the tool 108 are synchronized with imaging data coordinates to ensure alignment with the intended outline. The tool’s operation is continuous and precise, producing clear, reproducible boundaries without manual adjustment, thereby enabling high-fidelity marking in accordance with platform 101 specifications.

[0042] The multi-axis slider 110 mentioned herein enables controlled translational movement of the marker tool 108 along three or more spatial dimensions. Upon command, the slider 110 positions the marker accurately across the X, Y, and Z axes, translating digital imaging coordinates into physical movement. The operation of the slider 110 ensures smooth, stepwise or continuous motion while maintaining alignment with the rectangular frame 109 and articulated link 111. The slider 110 compensates for angular or positional variations, allowing the marking tool 108 to follow complex trajectories with precision.

[0043] The articulated link 111 mentioned above connects the rectangular frame 109 and marker tool 108, permitting controlled rotational and angular adjustments. During operation, the link 111 responds to positional commands, enabling the marker to pivot, tilt, or extend to follow three-dimensional contours. The link’s joints absorb minor misalignments while preserving the trajectory defined by imaging data. The movements of the link 111 are synchronized with the multi-axis slider 110 to maintain constant contact and orientation relative to the target surface. The articulated link 111 ensures that outlines are accurately traced over irregular or inclined surfaces.

[0044] A plurality of pneumatic probes 112 provided with the platform 101, integrated with a sensor array, operates through pressurized air or gas to penetrate or contact the site of interest for sample collection. Each probe is configured to extend and retract under controlled pneumatic pressure, enabling precise interaction with surfaces or materials. The airflow within the probes 112 facilitates suction, enabling particulate, liquid, or gaseous samples to be drawn into internal chambers. The probes 112 are coupled to micro valves that regulate pressure and flow, ensuring sample integrity.

[0045] The sensor array herein functions as an integrated suite of detection units, comprises of a biosensor, a gas sensor, a LIBS (laser induced breakdown spectroscopy) sensor, and an optical spectrophotometric sensor for receiving real-time inputs from the pneumatic probes 112 and transmitting data to the AI camera 104. The data streams from the array are processed to correlate environmental and material parameters. The array coordinates sampling intervals, sensor activation, and calibration cycles, ensuring continuous monitoring without cross-interference. The signals from the sensors are digitized, normalized, and packaged for AI analysis.

[0046] The biosensor herein operates by transducing biological interactions into measurable electronic signals. Upon contact with target biomolecules at the site, the sensor’s receptor elements bind specific analytes, triggering electrochemical, optical, or piezoelectric responses. The responses are converted into voltage, current, which are then amplified and digitized. The biosensor enables real-time detection of pathogens, enzymes, or other biomolecules. The signal outputs are analyzed for concentration, reaction kinetics, and presence/absence detection, enabling rapid and precise biological assessment of the collected samples without requiring separate laboratory processing.

[0047] The gas sensor operates by detecting and quantifying gaseous species at the site through physical or chemical transduction. The target gas molecules interact with the sensor’s reactive surface or semiconducting layer, altering electrical resistance, capacitance, or thermal conductivity. The sensor converts the changes into measurable electronic signals, which are relayed to the microcontroller. The microcontroller interprets concentration levels, enabling differentiation of gas types and detection thresholds. The sensor provides spatial and temporal mapping of gas distribution.

[0048] The LIBS sensor herein operates by directing high-energy laser pulses onto the target sample to create a micro plasma. The plasma emits light characteristic of the elemental composition of the sample. This emitted light is collected by optical fibers and transmitted to a spectrometer, where it is dispersed into wavelength. Detectors capture the spectral lines, which are then analyzed electronically to identify and quantify elements present. The optical spectrophotometric sensor mentioned above operates by measuring the intensity of light transmitted, reflected, or absorbed by a sample across specific wavelengths.

[0049] Light sources illuminate the sample, and photodetectors capture transmitted or reflected signals. Variations in intensity correlate with chemical composition, concentration, or physical properties. The sensor synchronizes illumination, detection, and data logging, enabling high-resolution spectral mapping. The microcontroller converts optical signals into absorbance or transmission spectra, which are further analyzed to determine sample characteristics.

[0050] A sample collection module integrated with the platform 101 and designed for the precise acquisition and secure storage of sample from a designated site of interest. Upon deployment, the module interfaces with the microcontroller, enabling automated or remote actuation of the collection tools. The sample collection module includes a parallelogram linkage unit 113 installed on the platform 101 and integrated with a motorized gripping unit 114. The module engages the appropriate instrument based on the sample type, executes collection protocols, and transfers the gathered material directly into a sterile container 115 integrated with the platform 101.

[0051] The module ensures contamination-free handling through controlled mechanical movement, environmental isolation, and immediate containment, maintaining sampling integrity from site collection through transport and storage for examination. The parallelogram linkage unit 113 herein functions to provide stable, consistent, and linear motion of the gripping assembly while maintaining the orientation of the attached collection tools. The linkage unit 113 converts rotational or linear input from the platform’s actuator into precise parallel displacement, enabling the gripper to approach collection points accurately.

[0052] This operation ensures that tools remain aligned with the target surface throughout their range of motion, preventing misalignment or inadvertent contact. The linkage unit 113 allows the gripping unit 114 to apply controlled pressure, suction, or vacuum as required by maintaining constant angular orientation, thereby optimizing collection efficiency while minimizing disturbance to the sample or surrounding environment. The set of interchangeable tools includes micro-suction nozzles, motorized pincers, vacuum-assisted collectors including a micro-filtration chamber and fine mesh trap, and a plurality of sterile swabs.

[0053] The motorized gripping unit 114 is designed to selectively engage and manipulate the interchangeable tools mounted on the platform 101. Upon command, the gripping unit 114 extends or retracts toward the target substrate, activating motors to adjust grip force, orientation, and tool deployment. The gripping unit 114 ensures that the interchangeable tools are positioned with precision and applies calibrated force to acquire materials without degradation. The micro-suction nozzles herein operate by generating a controlled negative pressure to aspirate liquid or semi-liquid samples, such as blood, sweat, or other bodily fluids, directly from the surface. Upon activation, the nozzle is precisely positioned by the gripping and linkage unit 113, creating a localized suction zone that draws the sample into the nozzle chamber. The aspirated liquid is then conveyed through an enclosed channel to directly into the sterile container 115.

[0054] The motorized pincers function to capture small solid samples, including hair strands, fibers, or trace objects, by applying a controlled gripping force. The pincers are actuated by the microcontroller to extend toward the target, open to encompass the sample, and close precisely without crushing or damaging it. Once the material is grasped, the pincers retract, holding the sample firmly while transferring it to the sterile container 115. The vacuum-assisted collectors mentioned above function by drawing particulate matter, dust, soil, or powder traces into an airflow stream. The collected materials pass through the micro-filtration chamber that captures fine particles, while larger debris is trapped by the fine mesh filter. Upon completion, the trapped particulate matter remains contained within the chamber and mesh assembly, which is then transferred to the sterile container 115.

[0055] The sterile swabs herein operate as disposable, absorbent instruments for collecting trace biological or chemical residues, including DNA, fingerprints, or surface contaminants. Each swab is mounted on the motorized gripper, precisely aligned with the target area. The swab is applied with controlled pressure and motion to maximize sample adherence without altering or destroying the substrate. After collection, the swab is retracted, maintaining sterility, and inserted directly into the sterile container 115. Multiple swabs allow sequential or simultaneous collection across different surfaces or sample types, ensuring cross-contamination prevention.

[0056] The sterile container 115 functions as a secure receptacle for all collected samples, preventing contamination and degradation. Upon receipt of materials from the gripping unit 114 or other tools, the container 115 seals the samples within a controlled internal environment. The container 115 is compatible with both liquid and solid specimens, maintaining environmental isolation and mitigating exposure to external particulates or microbial contamination. Following collection, the container 115 allows safe transport, storage, and chain-of-custody documentation. A first articulated arm 116 is equipped with a V-shaped plate 117 affixed to the platform 101, designed for the manipulation and parting of dense or obstructed vegetation to facilitate the exposure of concealed specimens for collection.

[0057] The articulated arm 116 comprises multiple pivotally connected segments enabling precise angular displacement and spatial positioning. The V-shaped plate 117 serves as a mechanical interface, directing and separating foliage without causing damage to surrounding materials, thereby creating an accessible path for subsequent retrieval. The articulated arm 116 operates via sequential pivot points allowing rotational and linear movement across three-dimensional space. Upon positioning, the V-shaped plate 117 engages with the target area, its edges guiding and displacing dense foliage laterally. The microcontroller adjusts the arm’s segments to vary the angle and reach, ensuring complete exposure of hidden objects.

[0058] An adhesive dispensing arrangement and integrated with the platform 101 to collect trace data from a site of interest. The arrangement dispenses adhesive in a controlled and precise manner while the platform 101 maneuvers across the surface. The adhesive dispensing arrangement comprises of a roller 118 having refillable pockets filled with adhesive installed on a free-end of a robotic link 119 integrated on the platform 101, a plurality of micro holes 120 distributed on surface of the roller 118, and a plurality of pusher plate 121 integrated with the roller 118. Upon activation, the robotic link 119 positions the roller 118 over the target area, and then the adhesive is released through the roller’s micro holes 120. The dispensing is synchronized with roller 118 motion to ensure uniform coverage.

[0059] As the roller 118 rotates over the target surface, each pocket reaches the point of adhesive application, enabling precise dispensing. The pockets are designed to retain adhesive until mechanical pressure is applied via the pusher plates 121. Once the pockets engage with the micro holes 120 under controlled force, adhesive is released. The micro holes 120 are uniformly distributed across each adhesive-containing pocket. During roller 118 rotation, the micro holes 120 serve as controlled conduits for adhesive release. The adhesive flows through the micro holes 120 only when pressure is applied by the integrated pusher plates 121.

[0060] During roller 118 operation, the pusher plates 121 exert a specified, controlled force on the pockets, thereby causing adhesive to be expelled through the micro holes 120. The force applied is synchronized with the roller’s rotational speed and the robotic link’s movement to ensure uniform dispensing. Each plate 121 operates independently, enabling localized pressure adjustment for precise adhesive release. This operation ensures accurate deposition, maintains consistent pocket emptying, and prevents leakage or over-application.

[0061] The microcontroller herein preferably is a central control unit of the device, regulating all operational functions with precision and reliability. The microcontroller manages motorized movements, coordinates sensor inputs, and ensures seamless integration between data collection, sample storage, and peripheral modules. Through real-time processing, the microcontroller enables automated responses, monitors status, and executes instructions to maintain accurate and consistent performance. The microcontroller also facilitates communication among interconnected components, synchronizing actions across the device to prevent errors, optimize efficiency, and support uninterrupted operations.

[0062] An automated sprayer 122 installed on a second articulated arm 123 with telescopic sections, engaging a micro-pump to draw the disinfectant solution from the reservoir. The microcontroller controls flow rates via integrated valves, ensuring consistent pressure for uniform mist generation. Upon reaching the designated site, the sprayer 122 dispenses the disinfectant through fine mist nozzles, covering surfaces and surrounding air. The movement patterns are executed automatically, adjusting spray angles in real-time. The second articulated arm 123 functions through a series of motorized joints, allowing multidirectional movement along three-dimensional axes.

[0063] Upon receiving control signals by the microcontroller, the arm 123 extends telescopic sections to reach specified locations. Each joint is actuated by servo motors, providing precise positioning and angular adjustments. The arm 123 stabilizes during sprayer 122 operation to maintain a constant orientation of the nozzles relative to surfaces. The micro-pump herein draws the disinfectant from the reservoir, generating sufficient pressure to deliver a continuous and controlled flow to the spray nozzles. The pump’s precision enables fine control over droplet size and coverage. The fine mist nozzles atomize the disinfectant into sub-micron droplets, generating a uniform aerosol for comprehensive surface and ambient coverage.

[0064] The nozzles operate by constricting high-pressure fluid from the micro-pump through precision-engineered orifices, producing consistent spray patterns. The mist settles evenly on surfaces, ensuring disinfection efficiency while preventing pooling. A deterrent module comprises of ultrasonic emitters 124 and low-intensity light flashers 125 are integrated on the platform 101 and operating automatically upon detection of pests or insects via the camera 104. Upon activation, the module simultaneously triggers the ultrasonic emitters 124 and low-intensity light flashers 125 to actively deter pests from the vicinity, thereby preventing contamination.

[0065] The module functions continuously in real-time, maintaining a protective barrier around the platform 101. The module is configured for minimal human intervention, responsive to dynamic pest activity, and ensures that deterrence is non-lethal and environmentally compliant. The ultrasonic emitters 124 herein operate by generating high-frequency sound waves, typically above 20 kHz, beyond the auditory range of humans. Upon detection of pests, the emitters 124 produce continuous or pulsed ultrasonic signals that disrupt the pests’ auditory and nervous systems, inducing discomfort and disorientation. This operation compels pests to vacate the treated area without causing physical harm.

[0066] The low-intensity light flashers 125 herein function by emitting intermittent, controlled bursts of visible light upon pest detection. These flashes are designed to trigger aversion responses in insects and small pests, causing temporary disorientation and encouraging immediate vacating of the illuminated zone. The flashers 125 are synchronized with the camera 104 to activate only in the presence of pests, ensuring energy efficiency. An audio module comprising a speaker 126 and a microphone 127, configured to interface with the platform 101 for both outputting auditory alerts and receiving voice-based commands.

[0067] Upon activation, the module captures sound via the microphone 127, processes input signals through a voice recognition protocol, and converts them into actionable commands. Simultaneously, the module transmits processed audio signals to the speaker 126, generating alerts or responses. The module operates in real-time, ensuring secure, responsive communication between the user and the platform 101, thereby facilitating controlled execution of functions and prompt notification delivery in accordance with operational protocols. The speaker 126 converts electrical audio signals into sound waves through electromechanical transduction.

[0068] The electrical signal induces current through a coil, generating a magnetic field that interacts with a fixed magnet, causing the attached diaphragm to oscillate. These oscillations create variations in air pressure, producing audible sound waves corresponding to the original signal. The intensity and frequency of the input signal dictate the amplitude and pitch of the sound output. In operation, the speaker 126 ensures precise reproduction of alerts or voice responses from the platform 101, enabling users to perceive and respond to notifications effectively and reliably within the prescribed functional parameters. The microphone 127 herein functions by converting acoustic sound waves into corresponding electrical signals. The sound waves strike a diaphragm, causing mechanical vibrations proportional to the wave’s amplitude and frequency.
