DETAILED DESCRIPTION OF THE INVENTION

[0014] The present invention relates to a multi-vehicle parking and transportation ferry that is capable of safely transporting multiple vehicles across water bodies while ensuring structural stability, automated monitoring, autonomously security screening, and adaptive environmental response for improved safety, efficiency, and operational reliability.

[0015] Referring to Figure 1, an isometric view of a multi-vehicle parking and transportation ferry is illustrated, comprising a floatable platform 101 equipped with a plurality of pontoons 102 embedded at the base and each connected to a motorized air pump 103 via a conduit 104, a plurality of motorized thrusters 105 and propellers 106 attached to the platform 101, a folding bridge arrangement installed at each lateral end of the platform 101 and comprising a plurality of hingedly connected panels 107 and a pair anchoring towers 108 supporting a motorized pulley 109 with a pulling cable 110, the folding bridge arrangement is further equipped with a plurality of pneumatically extendable rods 111, a plurality of hydraulically actuating arms 112 are mounted on the bridge and each arm 112 coupled to a locking clamp 113, an RGB (red, green, blue) camera 114 installed at each bridge entrance, a speaker 115 installed with the platform 101, an inspection module 116 coupled to a telescopic arm 117 mounted on a linear slider 118 installed on the platform 101, a plurality of slots 119 installed in the platform 101 and each slot 119 supporting a pneumatic plate 120, each slot 119 further incorporating a linear sliding rail 121, each pneumatic plate 120 is equipped with a plurality of hydraulic actuators 122, each coupled to a grasping pad 123, a counterweight module comprising a plurality of heavy metal balls 124, each mounted on a separate slider 125 installed on the platform 101, an acoustic Doppler current profiler 126 integrated at each platform 101 base sides, a plurality of attached hydraulic stabilization bars 127 with base plates, an extendable link 128 having an ultrasonic deterrent 129 installed underneath the platform 101, a fuel suction module is installed on the platform 101 and comprises a robotic arm 130 coupled to a motorized gripper 131, a sealed storage container 132 connected to a suction hose 133 with suction nozzle 134 and a pump 135, a plurality of solar panels 136 are each mounted an individual extendable support column 137 via a motorized ball and socket joint 138, installed on the platform 101, an interactive display panel 139 is mounted on the platform 101, the a extendable link 128 further comprising a SONAR (sound navigation and ranging) 140.

[0016] The ferry disclosed herein includes the floatable platform 101 developed to be positioned on a water body, to facilitate transportation and temporary parking of multiple vehicles and personnel. The floatable platform 101 includes multiple pontoons 102 integrated at the base of the platform 101, each fluidly connected to the motorized air pump 103 through the conduit 104. A pressure sensor is disposed at an air inlet of each pontoon 102 to monitor internal air pressure. The sensed pressure data is continuously processed by a microcontroller integrated within the platform 101 to evaluate buoyancy conditions, and the motorized air pump 103 correspondingly regulates the air pressure within each pontoon 102 to maintain safe and stable buoyancy.

[0017] The pressure sensor converts internal air pressure into an electrical signal using a deformable diaphragm coupled with a piezoresistive sensing element. Diaphragm deflection causes resistance variation in a Wheatstone bridge, generating a proportional voltage signal, which is conditioned, temperature-compensated, digitized, and transmitted to the microcontroller for accurate, real-time buoyancy monitoring and control. The motorized air pump 103 operates by converting electrical energy into mechanical motion to generate controlled airflow for pontoon 102 pressurization. An electric motor drives a compression unit, creating pressure differential to draw and compress air. Check valves ensure unidirectional flow, while a control circuit regulates motor speed based on the microcontroller input.

[0018] The platform 101 is equipped with a stability monitoring unit comprising a gyroscope, an accelerometer, and multiple weight sensors to continuously monitor platform 101 orientation and load distribution. The stability monitoring unit initializes and establishes a baseline stability profile, and subsequently detects deviations indicative of weight imbalance conditions. Upon detection, the microcontroller activates the counterweight module including multiple movable masses, each positioned on the respective separate slider 125, to redistribute weight and restore platform 101 stability. The gyroscope detects angular velocity using Coriolis-induced motion in a microelectromechanical structure, where rotation causes capacitance variation converted into an electrical signal for transmission to the microcontroller. The accelerometer measures linear acceleration through displacement of a suspended mass, producing capacitance changes processed into a proportional signal. Both sensors continuously transmit real-time data to the microcontroller for analysis of the platform 101 motion, tilt, vibration, and overall stability. Each weight sensor converts applied load into an electrical signal using a strain-based sensor. A load cell with strain gauges in a Wheatstone bridge detects resistance changes due to deformation, generating a proportional voltage signal, which is conditioned and transmitted to the microcontroller for monitoring load distribution and imbalance detection.

[0019] Upon detection of weight imbalance conditions of the ferry by the stability monitoring unit, the microcontroller activates the counterweight module comprising multiple heavy metal balls 124, each mounted on the respective slider 125 installed on the platform 101, to redistribute mass and counterbalance the platform 101, thereby maintaining stability. The slider 125 operates as a guided linear motion unit enabling controlled displacement of the counterweight along a predefined path in response to imbalance. The slider 125 includes a carriage on a linear rail with low-friction bearings and a motor-driven unit converting rotational motion into linear movement, positioning the counterweight under microcontroller control.

[0020] Simultaneously, a global positioning system (GPS) and a plurality of light detection and ranging (LiDAR) modules are installed on the platform 101 and configured to facilitate safe navigation across water bodies by detecting and avoiding underwater obstacles, debris, and other navigation hazards. The GPS and LiDAR modules initiate real-time mapping of the surrounding environment to generate positional and spatial data for navigation and route optimization. The GPS module operates by receiving satellite signals through an antenna and processing them via an RF front-end and digital signal processor. Timing data is extracted and used by a navigation processor to compute real-time position through trilateration. The positional data is transmitted to the microcontroller for navigation and route control. The LiDAR module operates by emitting laser pulses and measuring time-of-flight of reflected signals to determine object distances. A laser emitter, photodetector, and processing unit generate three-dimensional spatial data, which is transmitted to the microcontroller for obstacle detection, environmental mapping, and navigation path optimization.

[0021] Multiple motorized thrusters 105 and propellers 106 are attached to the platform 101 and configured to provide controlled directional movement across water bodies. Based on positional and spatial data received from the global positioning system (GPS) and the plurality of light detection and ranging (LiDAR) modules, the microcontroller utilizes the motorized thrusters 105 and propellers 106 to maneuver and accurately align itself near a docking point for boarding and unloading operations. The motorized thrusters 105 operate by converting electrical energy into controlled mechanical thrust for vessel propulsion. Each thruster 105 comprises of an electric motor, a power electronic driver, and a sealed propeller housing. The electric motor, which is a brushless DC motor, rotates a drive shaft connected to a propeller. The motor controller regulates motor speed and torque based on command signals received from the microcontroller, thereby controlling thrust magnitude and direction. Rotation of the propeller blades generates a pressure differential in water, producing forward or reverse thrust for directional movement of the platform 101.

[0022] On the other hand, the propellers 106 comprise of a plurality of hydrodynamically shaped blades mounted on a hub fixed to the motor-driven shaft. Once rotated, the blades accelerate water in a controlled direction, producing a reactive force that propels the platform 101 according to Newtonian action-reaction principles. In case of multiple propellers 106, differential speed control between units enables steering and maneuvering. The generated thrust and directional control parameters are continuously adjusted by the motor controller coupled with the microcontroller based on navigation commands and sensor feedback to achieve precise movement, docking alignment, and stable navigation across water bodies.

[0023] The folding bridge arrangement is installed at each lateral end of the platform 101 and comprises of multiple hingedly connected panels 107 and the pair of anchoring towers 108 supporting the motorized pulley 109 with the pulling cable 110 configured to selectively deploy and retract the panels 107 to form a pathway for vehicles to access the platform 101. The folding bridge arrangement is further provided with the plurality of pneumatically extendable rods 111 configured to form side barriers along the pathway, thereby defining a secured travel corridor for vehicles. The folding bridge arrangement at the lateral end is actuated to initiate deployment or retraction of the vehicle access pathway. In operation, the folding bridge arrangement is selectively actuated during boarding or unloading sequences. Upon receiving a control signal from the microcontroller, the motorized pulley 109 is activated, causing controlled tensioning or release of the pulling cable 110, which drives the hingedly connected panels 107 to unfold or retract in a sequential manner. As the panels 107 deploy, they form a continuous access pathway between the platform 101 and the docking point.

[0024] The motorized pulley 109 comprises of an electric motor coupled to a pulley drum mounted on a rotational shaft, along with a motor driver for speed and torque regulation. The motor, when energized, rotates the shaft, causing the pulley 109 drum to wind or unwind the high-strength pulling cable 110. The cable 110 is routed through guide rollers connected to the hingedly linked bridge panels 107, such that controlled cable 110 tension results in coordinated angular movement of the panels 107 about their hinge joints. The plurality of hingedly connected panels 107 is rigidly formed and interconnected to adjacent panels 107 through hinge joints defining a rotational axis, enabling controlled angular movement between successive panels 107. The hinge joints include load-bearing pins and bushings that permit smooth articulation while maintaining structural continuity under vehicular loads. During operation, actuation forces applied via the motorized pulley 109 induce sequential rotation of the panels 107 about their respective hinge axes, transitioning the assembly between a folded configuration and an extended planar configuration. In the extended state, adjacent panels 107 align to form a continuous load-bearing surface, with mechanical stops maintaining planar alignment and preventing over-rotation. The panels 107 collectively distribute applied loads across the bridge structure, while allowing compact stowage when retracted.

[0025] Simultaneously, the pneumatically extendable rods 111 are actuated to extend along both lateral sides of the deployed bridge, forming protective barriers that define a confined and guided vehicle passage. The pneumatic extendable rods 111 regulate extension through controlled air pressure, ensuring synchronized and stable barrier formation. Once fully deployed, the microcontroller maintains the bridge in a locked position to allow safe vehicle movement, and upon completion of operations, the sequence is reversed to retract both the panels 107 and side barriers back to a stowed configuration. The extension and retraction of the pneumatically extendable rods 111 are driven by a pneumatic unit comprising an air compressor, cylinders, valves, and pistons operating in coordination under microcontroller control. Actuation of valves directs compressed air into the cylinders, generating pressure that drives pistons for linear extension of the rods 111, while reversing airflow enables retraction. The microcontroller regulates valve operation to control barrier formation and removal.

[0026] The RGB (red, green, blue) camera 114 integrated with an optical character recognition (OCR) module is installed at each bridge entrance and configured to monitor incoming personnel and vehicles. As vehicles approach, the RGB camera 114 with the OCR module captures visual and textual data, including vehicle and personnel identifiers. The captured data is processed by the microcontroller integrated with an artificial intelligence (AI) module employing facial expression recognition (FER) protocols and trained machine learning models, such as convolutional neural networks (CNN) and support vector machines (SVM), to analyze identity and behavior. Upon detection of suspicious behavior or restricted individuals, the microcontroller generates an alert via the embedded speaker 115.

[0027] The RGB camera 114 operates by capturing reflected light through a lens assembly and converting the light into digital image data. An image sensor with an RGB color filter array generates electrical signals proportional to light intensity at each pixel. The signals are read, processed, and converted into a full-color image through image signal processing functions including demosaicing and noise reduction. The resulting image data is transmitted to the microcontroller for further analysis and recognition. The OCR module converts captured image data into machine-readable text using image processing and pattern recognition. The OCR module includes preprocessing, segmentation, feature extraction, and classification stages executed on a processor. The image is enhanced and segmented to isolate text regions, followed by extraction of structural features and recognition using a trained model. The recognized text is converted into digital data and transmitted to the microcontroller for identification and validation of vehicle and personnel information.

[0028] The AI module processes captured facial image data to identify expressions and behavioral indicators using the facial expression recognition protocols and trained machine learning models. The AI module includes preprocessing, face detection, feature extraction, and classification stages. Facial regions are detected and normalized, then analyzed using a trained deep learning model to extract feature representations. These features are classified against a trained dataset to determine behavioral states. The output is evaluated to identify normal or suspicious behavior and transmitted to the microcontroller for real-time alert generation and response. If suspicious behavior is detected via the camera 114, the embedded speaker 115 generates an audible alert. The speaker 115 operates by converting an electrical signal into sound waves. The speaker 115 comprises of a diaphragm connected to a voice coil positioned within a magnetic field generated by permanent magnets. When an electrical signal is applied, the voice coil generates a varying electromagnetic field that interacts with the magnetic field, producing controlled motion of the coil and diaphragm. This motion displaces air to generate sound waves corresponding to the input signal, thereby producing an audible alert to notify the user and prompt appropriate action.

[0029] The inspection module 116 is coupled to the telescopic arm 117 mounted on the linear slider 118 installed on the platform 101 and configured to precisely position the inspection module 116 for conducting a detailed inspection of entering vehicles. The inspection module 116 comprises an optical character recognition (OCR) reader, a radio frequency identification (RFID) verification unit, a biometric sensor, an X-ray baggage scanner, a metal detector, an odor sensor, and a radar configured to analyze vehicle documents, carried items, and internal contents, and to detect fuel leakage and excessive fuel levels. The acquired inspection data is processed by an artificial intelligence (AI) module, which classifies the vehicle condition and identifies suspicious or abnormal conditions. Upon such detection, the microcontroller generates an alert via the embedded speaker 115. The linear slider 118 operates in a manner similar to the slider 125 disclosed above and is configured to enable controlled linear positioning of the coupled inspection module 116 along a predefined path. Similarly, the telescopic arm 117 operates in a manner analogous to the pneumatically extendable rods 111 disclosed above and is configured to enable controlled extension and retraction for precise positioning of the inspection module 116 during inspection operations.

[0030] The optical character recognition (OCR) reader operates by capturing document images using an optical imaging sensor and converting them into machine-readable text. The OCR reader comprises of a lens assembly, an image sensor, and an image processing unit. Captured images are preprocessed for noise reduction, contrast enhancement, and segmentation, after which character features are extracted and recognized using pattern matching or a trained neural network. The recognized alphanumeric data is transmitted to the microcontroller for identity verification and record analysis. The radio frequency identification (RFID) verification unit operates by wirelessly reading data stored in RFID tags attached to vehicles or documents. The verification unit comprises an RF transmitter, RF receiver, and antenna coil. The transmitter emits an electromagnetic interrogation signal, which activates a passive RFID tag. The tag responds by modulating and retransmitting stored identification data. The received signal is demodulated and decoded into digital information, which is forwarded to the microcontroller for authentication and verification.

[0031] The biometric sensor operates by capturing and analyzing physiological characteristics for identity verification. In an embodiment of the present invention, the biometric sensor includes a fingerprint scanner or facial recognition sensor comprising an optical sensing array. The sensor detects ridge patterns or facial geometry and converts them into digital biometric templates. These templates are processed by a matching protocol, such as minutiae-based matching or deep learning-based pattern recognition, that compares them against stored reference data, and the resulting authentication output is transmitted to the microcontroller. The X-ray baggage scanner operates by emitting controlled X-ray radiation through a vehicle or baggage compartment and detecting transmitted radiation. The X-ray baggage scanner includes an X-ray source, collimator, detector array, and signal processing unit. Variations in radiation absorption are converted into electrical signals and processed to generate images for inspection and anomaly detection. The metal detector operates by generating an alternating electromagnetic field using a transmitter coil and detecting disturbances caused by metallic objects. Changes induced by eddy currents are received by a coil, converted into electrical signals, and analyzed by the microcontroller to detect metal presence and proximity.

[0032] The odor sensor operates by detecting volatile chemical compounds in the air using a gas-sensitive sensing element. The odor sensor includes a metal oxide semiconductor (MOS) sensing layer. When exposed to gases such as fuel vapors, the sensor’s resistance output changes proportionally to gas concentration. The analog signal is conditioned and converted into digital data for transmission to the microcontroller for leak or anomaly detection. The radar operates by transmitting high-frequency radio waves and analyzing their reflections from surrounding objects. The radar includes a radar transmitter, receiver, and signal processing module. The transmitted waves reflect off objects and return to the receiver with time delay and frequency shift. These signals are processed using Doppler and time-of-flight analysis to determine object distance, velocity, and movement characteristics. The processed radar data is provided to the microcontroller for spatial awareness and hazard detection.

[0033] Multiple hydraulically actuating arms 112 are mounted on the bridge, each arm 112 being coupled to the locking clamp 113 configured to engage and secure the wheels of a vehicle identified as suspicious by the inspection module 116, thereby immobilizing the vehicle. Upon classification of a vehicle as suspicious, the hydraulically actuating arms 112 are actuated to extend the locking clamps 113 and immobilize the vehicle in position. The hydraulically actuating arms 112 operate by converting hydraulic fluid pressure into controlled linear and/or angular mechanical motion for actuation of the locking clamps 113. Each hydraulic arm 112 includes a hydraulic cylinder, piston assembly, pump, control valves, and fluid lines connected to a pressurized reservoir. Upon a control signal from the microcontroller, a directional valve directs pressurized fluid into the cylinder, generating force on the piston to extend or retract a rod coupled to the locking clamp 113 for wheel immobilization. Retraction is achieved by reversing fluid flow through the control valve to return fluid to the reservoir. The locking clamp 113 includes a pair of opposing jaws, a pivot linkage assembly, and an actuation interface coupled to a hydraulic drive of the actuating arm. Linear force from the hydraulic drive is transmitted through the linkage and converted into a closing motion of the jaws. The jaws include high-friction or deformable pads to enhance grip and prevent slippage.

[0034] The fuel suction module is installed on the platform 101 and comprises of the robotic arm 130 coupled to the motorized gripper 131 with an integrated position monitoring sensor for precise positioning over a fuel tank cap to facilitate opening thereof. The fuel suction module further includes the sealed storage container 132 with a level sensor, connected to the suction hose 133 having the suction nozzle 134 and the pump 135 for controlled extraction and storage of excess fuel detected by the odor sensor and radar, enabling the microcontroller to generate an alert upon detection of fuel levels exceeding a predefined threshold stored in the microcontroller’s memory. Upon detection of excessive fuel, the fuel suction module is activated, where the robotic arm 130 with the motorized gripper 131 opens the fuel tank cap, the pump 135 draws fuel through the suction hose 133 and nozzle 134 into the sealed storage container 132, and the level sensor continuously monitors the stored fuel quantity and triggers an alert when the storage limit is exceeded.

[0035] The robotic arm 130 precisely manipulates the motorized gripper 131 for fuel cap engagement and operation. The arm 130 includes articulated links connected by rotary joints driven by electric actuators such as servo motors with gears. The actuators receive control signals from the microcontroller to produce coordinated multi-axis motion. Position feedback from the position monitoring sensor ensures accurate alignment. The distal end supports the motorized gripper 131 for precise placement, while the microcontroller executes inverse kinematics-based control to convert target coordinates into joint-level actuation for controlled positioning. The position monitoring sensor operates by continuously determining the spatial position and orientation of the robotic arm 130 and motorized gripper 131 relative to a reference frame. The position monitoring sensor includes an encoder-based feedback unit with rotary encoders on actuator shafts and/or linear position sensors at arm 130 joints. The encoders generate pulse signals corresponding to angular or linear displacement, which are converted into digital position data via signal conditioning circuitry. The processed data is transmitted to the microcontroller, which compares real-time position data with stored target coordinates and performs closed-loop control of actuators to correct deviations and ensure precise alignment.

[0036] The motorized gripper 131 grasps, manipulates, and releases the fuel tank cap. The gripper 131 includes a pair of opposing jaws mounted on a support housing, each driven by a servo motor with a lead screw. Upon control signals from the microcontroller, the motor converts electrical energy into mechanical motion to open or close the jaws through linear actuation. Gripping force is regulated via motor torque control to ensure secure engagement without damage. Position feedback from the position monitoring sensor ensures accurate jaw alignment and repeatability, enabling coordinated operation with the robotic arm.

[0037] The suction hose 133 used to transport fuel from a source location to the storage container 132. The hose 133 is formed of chemically resistant, anti-static material and is fluidly connected at one end to the suction nozzle 134 and at the other end to a pump inlet. The suction nozzle 134 is configured with a shaped intake opening and a one-way valve to prevent backflow and ensure controlled intake of liquid fuel. The robotic arm 130, via the motorized gripper 131, positions and stabilizes the suction nozzle 134 over or into the fuel tank opening, ensuring proper alignment and sealing to enable efficient extraction. The pump 135 draws fuel through the suction hose 133 and transfer the fuel to the sealed storage container 132. The pump 135 comprises of a motor-driven impeller driven by an electric motor and controlled by the microcontroller. Upon activation, the pump 135 creates a pressure differential between the suction inlet and outlet, thereby inducing fuel flow through the suction nozzle 134 and hose 133.

[0038] During operation, the robotic arm 130 with the motorized gripper 131 precisely positions the suction nozzle 134 at the fuel tank inlet and maintains its position using feedback from the position sensors. Once alignment is confirmed, the microcontroller activates the pump 135, causing fuel to be extracted through the suction hose 133 and delivered into the sealed storage container 132. The microcontroller continuously monitors fuel level via the level sensor in the storage container 132, and the robotic arm 130 maintains or adjusts nozzle 134 positioning as required until the extraction process is completed or the predefined threshold is reached. The level sensor detects the quantity of fuel within the sealed storage container and converts the quantity of fuel into an electrical signal for monitoring and control. The level sensor operates as a capacitive type float-based sensor, where variations in fuel level change the dielectric constant between probe and reference electrodes, resulting in a corresponding change in capacitance. This capacitance variation is converted into a proportional electrical signal and transmitted to the microcontroller. The microcontroller compares the level data with a predefined threshold stored in the microcontroller’s memory and, upon exceeding the limit, stops the pump 135 and generates an alert to prevent overfilling of the storage container 132.

[0039] A communication module is integrated with the microcontroller and configured to establish wireless connectivity with a computing unit having an inbuilt user interface for remote monitoring, control, and alert management of ferry operations. The microcontroller activates the communication module to establish a wireless link with the computing unit, which includes a smartphone, tablet, or laptop, enabling user input of control commands and reception of ferry status and alerts. The communication module includes, but is not limited to, Wi-Fi, Bluetooth, or GSM, and is preferably a Wi-Fi module operating over a wireless local area network in accordance with IEEE 802.11 standards. The module enables bidirectional transmission of operational data and alerts, and upon detection of abnormal or predefined conditions, transmits real-time notifications to the computing unit for remote user response.

[0040] Multiple slots 119 are installed in the platform 101, each slot 119 supporting the pneumatic plate 120 configured to extend vertically for securing a vehicle. Each slot 119 further incorporates the linear sliding rail 121 configured to adjust the positioning of the pneumatic plate 120 based on feedback from integrated ultrasonic and optical sensors. Each pneumatic plate 120 is provided with multiple hydraulic actuators 122, each coupled to the grasping pad 123 configured to extend and firmly engage the vehicle, thereby ensuring stable positioning and preventing displacement during transit operations. Cleared vehicles are guided into the respective slots 119, where the linear sliding rail 121 performs positioning adjustments based on the ultrasonic and an optical sensor feedback, the pneumatic plate 120 extends vertically to secure the vehicle, and the hydraulic actuators 122 actuate the grasping pads 123 to immobilize the vehicle. The pneumatic plate 120 stabilizes and immobilizes the vehicle within the slot 119 of the platform 101. The pneumatic plate 120 functions in a similar manner as the pneumatically extendable rods 111 disclosed above and is configured to extend and retract under controlled pneumatic pressure to provide vertical engagement, secure positioning, and stable support of the vehicle. The linear sliding rail 121 provides controlled lateral adjustment of the pneumatic plate 120 within each slot 119. The sliding rail 121 includes a rail track, carriage assembly, and a lead screw actuator driven by an electric motor. The carriage, mounted on low-friction bearings, moves along the rail for smooth linear motion. Upon microcontroller control, the motor rotates the lead screw to convert rotational motion into linear displacement of the carriage and attached pneumatic plate 120, enabling precise repositioning for accurate vehicle alignment and secure engagement.

[0041] The ultrasonic sensor emits high-frequency acoustic pulses through a transmitting transducer and measures the time-of-flight of reflected echoes from a target surface. The ultrasonic sensor includes a piezoelectric transducer, signal generator, and time-of-flight measurement circuit. The reflected waves are received and converted into electrical signals, which are processed to determine distance based on time delay. The resulting distance data is transmitted to the microcontroller for spatial positioning and alignment control. The optical sensor detects reflected or transmitted light from a target surface to determine position or presence. The optical sensor includes a light emitter such as an LED or laser diode, a photodetector such as a photodiode or phototransistor, and a signal conditioning circuit. The emitter projects a light beam toward the target, and the reflected or interrupted light is received by the photodetector and converted into an electrical signal. The signal is amplified and processed to determine object presence, alignment, or displacement. The processed data is transmitted to the microcontroller and used with ultrasonic sensor data for precise positioning and adjustment of the linear sliding rail 121 and pneumatic plate 120.

[0042] The hydraulic actuators 122 operates in a manner similar to the hydraulic arm 112 disclosed above and is configured to convert hydraulic fluid pressure into controlled linear motion for extension and retraction of the coupled grasping pad 123. The actuators 122 selectively extends the grasping pad 123 to engage and secure a vehicle and retracts the same upon release of hydraulic pressure, thereby enabling controlled gripping, stabilization, and disengagement of the vehicle. After securing the vehicle, the stability monitoring unit continuously monitors the platform 101 for weight imbalance conditions. Upon detection of an imbalance, the microcontroller activates the counterweight module comprising the plurality of heavy metal balls 124 mounted on the respective sliders 125, which are actuated to redistribute weight and restore platform 101 balance.

[0043] The acoustic Doppler current profiler 126 is integrated at the base sides of the platform 101 and configured to detect water current velocity and wave conditions. The acoustic Doppler current profiler 126 continuously monitors river conditions and transmits data to the microcontroller. Upon detection of strong currents or wave activity, the microcontroller activates multiple hydraulic stabilization bars 127 with the base plates, which operate in a manner similar to the hydraulic arm 112 disclosed above. Each stabilization bar 127 is further equipped with a laser sensor configured to measure river depth, and the extension of the stabilization bars 127 is adjusted based on the measured depth to maintain platform 101 balance under varying water conditions. The laser sensor emits a coherent light beam toward a target surface and determines distance based on time-of-flight or phase-shift measurement. The laser sensor includes a laser diode emitter, collimating lens, photodetector, and timing or phase measurement circuit. The emitted beam reflects from the riverbed and is received by the photodetector, which converts the captured beam into an electrical signal. Distance is computed from time delay or phase difference and processed by an internal signal unit. The resulting data is transmitted to the microcontroller for real-time adjustment of hydraulic stabilization bar 127 extension to maintain balance of the platform 101.

[0044] The SONAR (sound navigation and ranging) 140 coupled with an infrared sensor is mounted on the underside of the platform 101 via the extendable link 128 and configured to monitor underwater conditions and detect the presence of nearby wildlife. The SONAR 140 and infrared sensor continuously scan the underwater environment and transmit detection data to the microcontroller. Upon detection of wildlife within a predefined proximity, the microcontroller activates the embedded ultrasonic deterrent 129, which emits high-frequency sound waves to safely deter the detected wildlife from approaching the platform 101. The extension and retraction of the extendable link 128 operates in a manner similar to the extendable rods 111 disclosed above and is configured to enable controlled deployment and withdrawal of the SONAR 140 and infrared sensor for underwater monitoring. The extendable link 128 is actuated to position the sensors at a desired depth during operation and retracted to a stowed configuration when not in use. The SONAR 140 operates by transmitting acoustic pulses into the underwater environment and analyzing reflected echoes to determine object presence and distance.

[0045] The SONAR 140 includes a piezoelectric transducer, signal generator, receiver, and time-of-flight measurement circuit. The emitted sound waves propagate through water and reflect from objects or wildlife. The reflected signals are received and converted into electrical signals, and the time delay between transmission and reception is processed to determine range and spatial location. The resulting data is transmitted to the microcontroller for underwater monitoring and target identification. The infrared sensor detects thermal radiation emitted by underwater objects to identify living organisms. The infrared sensor includes an infrared emitter, photodetector, and signal conditioning circuit. Variations in infrared intensity corresponding to temperature differences are converted into electrical signals by the photodetector, then amplified and processed to generate detection outputs. The processed infrared data is transmitted to the microcontroller and correlated with SONAR data to improve accuracy of wildlife detection and proximity assessment.

[0046] The ultrasonic deterrent operates by generating and emitting high-frequency acoustic waves to deter underwater wildlife without physical contact. The ultrasonic deterrent includes a signal generator, power amplifier, and piezoelectric transducer array. Upon a control signal from the microcontroller, the generator produces ultrasonic-frequency oscillations, which are amplified and converted by the transducers into mechanical vibrations to emit acoustic waves. The waves propagate through water to create an acoustic field that induces discomfort or disorientation in aquatic organisms, prompting them to move away from the platform 101. Frequency, pulse duration, and intensity are regulated by the microcontroller for controlled and safe operation. The ferry initiates movement using the motorized thrusters 105 and propellers 106. Navigation is guided by data received from the global positioning system (GPS) and the plurality of light detection and ranging (LiDAR) sensors configured to detect debris, obstacles, and navigation hazards. Based on this data, continuous control adjustments are performed to ensure safe and efficient travel across the water body.

[0047] Multiple solar panels 136 are mounted on the respective extendable support columns 137 via the motorized ball-and-socket joint 138 and installed on the platform 101. Each solar panel 136 is configured to adjust its orientation based on input from an ultraviolet (UV) sensor that detects sunlight intensity and direction, thereby optimizing panel 136 positioning for maximum solar energy harvesting. The harvested solar energy is supplied to the onboard electrical components of the platform 101 to provide eco-friendly power. The extension and retraction of the extendable support columns 137 operates in a manner similar to the extendable rods 111 disclosed above and is configured to enable controlled vertical deployment and stowage of the solar panels 136 mounting structure.

[0048] The motorized ball-and-socket joint 138 comprises a motor controlled by the microcontroller, a ball element, and a socket housing, where the ball is rotatably retained within the socket to enable multi-directional orientation. The motor selectively rotates the ball element under microcontroller control to adjust the angular position of the solar panels 136. Electrical drive signals are supplied to the motor to achieve controlled rotation within the joint, thereby enabling optimal alignment of the solar panels 136 with sunlight for enhanced energy harvesting. The UV sensor detects ultraviolet radiation intensity and converts the radiation intensity into an electrical signal for processing. The UV sensor includes a UV-sensitive photodiode, an optical filter, and a signal conditioning circuit. The optical filter selectively passes ultraviolet wavelengths while attenuating visible and infrared light. Incident UV radiation generates a photocurrent proportional to intensity, which is converted into voltage via a transimpedance amplifier and digitized through an analog-to-digital converter. The resulting signal is transmitted to the microcontroller for real-time adjustment of solar panel 136 orientation to optimize energy harvesting.

[0049] The solar panels 136 operates by converting incident solar radiation into electrical energy through the photovoltaic effect. The solar panels 136 comprise of a plurality of semiconductor photovoltaic cells, typically formed from doped silicon p-n junctions, encapsulated within a protective glass layer and mounted on a conductive backplane. When sunlight strikes the photovoltaic cells, photons excite electrons within the semiconductor material, generating electron-hole pairs. The built-in electric field at the p-n junction drives charge carriers in opposite directions, producing a direct current (DC) output across the cell terminals. The generated electrical output is collected through metallic interconnects and routed to a power conditioning circuit comprising a charge controller and voltage regulation unit. The conditioned electrical energy is then supplied to the ferry, while performance is optimized based on orientation adjustments controlled by the microcontroller.

[0050] The interactive display panel 139 is mounted on the platform 101 and enables user payment for ferry services, displays real-time vehicle slot 119 availability, and provides operational status updates. The panel integrates a microphone for receiving voice input and communication, and a speaker for delivering audible alerts, instructions, and announcements during boarding, transit, and unloading operations. The interactive display panel 139 includes a touchscreen display unit, display driver circuit, processing interface, and communication module coupled to the microcontroller. The touchscreen detects user input and transmits signals for processing functions such as payment, slot 119 selection, and status queries. The display driver renders real-time data, while the microphone converts voice input into electrical signals and the speaker outputs corresponding audio, enabling interactive user communication.

[0051] Upon reaching the destination, the ferry performs docking operations using the motorized thrusters 105 and propellers 106 to achieve precise alignment with the docking point. Once properly aligned and stabilized, the folding bridge arrangement is deployed to establish a secure access pathway between the platform 101 and the dock. Subsequently, the pneumatic plates 120 are retracted and the hydraulic grasping pads 123 are disengaged to release the secured vehicles. The vehicles are then guided to exit the platform 101 in a controlled and sequential manner to ensure safe and orderly unloading.
