Description:FIELD OF THE INVENTION

[0001] The present invention relates to an autonomous potholes repairing device that repair a pothole present over a road surface in an automated manner by detecting the presence of pothole and cleaning and filling the pothole with an appropriate amount of mortar mixture required as per the volume of the pothole in an automated manner.

BACKGROUND OF THE INVENTION

[0002] Potholes are depressions or holes in road surfaces caused by the wear and tear of traffic and the natural elements, such as water and temperature changes. When water seeps into cracks in the pavement and expands during freezing, it weakens the road material, eventually causing chunks to break away, forming potholes. These potholes create hazards for drivers and pedestrians, potentially causing vehicle damage, accidents, and injuries. They also disrupt traffic flow. It is crucial to repair potholes promptly to maintain road safety, prevent further infrastructure damage, and minimize costs associated with more extensive repairs in the future.

[0003] Traditionally, potholes are repaired using manual methods and basic tools. Workers clean the pothole by removing loose debris and dirt using shovels or brooms. Next, they apply a patching material, typically asphalt or concrete, into the hole. The material is then leveled and compacted with hand tampers or rollers to ensure a smooth surface. While effective, these methods are labor-intensive and time-consuming, requiring significant manual effort for cleaning, filling, and compacting. The repairs are often temporary, as the materials used do not bond well or withstand extreme weather conditions, leading to frequent reoccurrence of potholes. Additionally, manual repairs cause traffic disruptions, increasing the risk of accidents. Inconsistent application and compaction result in uneven surfaces, compromising the durability of the repair.

[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 an autonomous potholes repairing device that is capable of filling a pothole present over a road surface with mortar mixture in an automated manner by preparing a suitable amount of mortar mixture as per the volume of the pothole. Additionally, the proposed device is also capable of uniformly spreading the mixture by applying an optimum amount of pressure in an automated manner to level the patch with the surface of the road.

[0022] Referring to Figure 1, an isometric view of an autonomous potholes repairing device is illustrated, comprising a cuboidal body 101 configured with plurality of motorized wheels 102 arranged beneath the body 101, an artificial intelligence based imaging unit 103 is installed on the body 101, a motorized disc 104 installed with the body 101 via an L-shaped telescopically operated rod 105 and equipped with plurality of bristles 106, a motorized drilling unit 107 assembled on the body 101 by means of an extendable L-shaped link 108, a robotic link 109 attached with the body 101 and integrated with a curved-shaped member 110 via a primary motorized ball-and-socket joint 111, a waste vessel 112 mounted on the body 101.

[0023] Figure 1 further illustrates a multi-sectioned chamber 113 arranged within the body 101, each section is connected with a mixing container 114 by means of a conduit 115 arranged between each of the section and container 114, an iris lid 116 is installed with each of the section, a motorized stirrer 117 installed within the container 114, an electronically controlled valve 118 arranged beneath the container 114, a pipe 119 lined with the container 114, a box 120 installed on the body 101, a robotic gripper 121 provided on the body 101, an extendable bar 122 with a leveling plate 123 attached via a secondary motorized ball-and-socket joint 124 installed on the body 101, a vacuum based suction unit 125 is installed on the body 101, a receptacle 126 integrated with the suction unit 125, a storage unit 127 provided on the body 101, and a thermal camera 128 is mounted on the body 101.

[0024] The device disclosed herein comprises of a cuboidal body 101 incorporating various components associated with the device and developed to be positioned on a ground surface of a roadway by means of multiple motorized wheels 102 (ranging from 4 to 6 in numbers) arranged underneath the body 101, each by means of a supporting rod. The body 101 serves as the core component of the device and is made from strong, lightweight, and water proof materials which includes but not limited to hardened steel, aluminum alloy, hard fiber, and composite materials. These materials offer strength and rigidity to the body 101 making the body 101 resistant to mechanical stress and pressure.

[0025] A user is required to activate the device manually by pressing a button installed on the body 101 and linked with an inbuilt microcontroller associated with the device. The button is a type of switch that is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conduction of electricity that tends to activate the device and vice versa.

[0026] After activation of the device by the user, the microcontroller generates a command to actuate an artificial intelligence based imaging unit 103 installed on the body 101 and synced with a LiDAR (Light Detection and Ranging) sensor installed on the body 101 to detect potholes and other visual anomalies of roadway. The artificial intelligence-based imaging unit 103 comprises of a high-resolution camera lens, digital camera sensor and a processor, wherein the lens captures multiple images from different angles and perspectives in vicinity of the body 101 with the help of digital camera sensor for providing comprehensive coverage of the roadway.

[0027] The captured images then go through pre-processing steps by the processor integrated with the camera. The processor carries out a sequence of image processing operation including pre-processing, feature extraction and classification in order to enhance the image quality, which includes adjusting brightness and contrast and removing any distortion or noise. The pre-processed images are transmitted to the microcontroller linked with the processor in the form of electrical signals.

[0028] Synchronously, the LiDAR (Light Detection and Ranging) sensor sends out rapid laser pulses in a sweeping motion. These pulses travel through the air and interact with the potholes and other visual anomalies of roadway. When the laser pulses encounter the potholes and other visual anomalies of roadway, the laser bounces off. The LiDAR sensor precisely measures the time it takes for these laser pulses to travel to the surface of the potholes and back to the sensor. This measurement is known as time-of-flight and as the LiDAR sensor continues to emit laser pulses and measure their time-of-flight, it creates a dense point cloud of data points. Each data point corresponds to a specific location on the roadway. By combining the time-of-flight data from multiple laser beams at various angles, the LiDAR builds a detailed 3D (three-dimensional) map of the roadway which is further transferred to the microcontroller linked with the LiDAR sensor.

[0029] The microcontroller processes the 3D (three-dimensional) map of the roadway and the signal received from the imaging unit 103 in order to detect the presence and location of the potholes and other visual anomalies of the roadway. Based on which the microcontroller generates a command to actuate the wheels 102 for maneuvering the body 101 over the surface and position in proximity to the pothole. The motorized wheels 102 are a circular object that revolves on an axle to enable the body 101 to translate easily. The supporting rods helps to maintain an optimum distance between the base of the body 101 and the surface to enable the body 101 to maneuver easily over the surface of the road.

[0030] A hub motor is integrated into the hub of the wheels 102. The hub motor is an electric motor that comprises of a series of permanent magnets and electromagnetic coils. When the motor is activated, a magnetic field is set up in the coil and when the magnetic field of the coil interacts with the magnetic field
of the permanent magnets, a magnetic torque is generated causing the stator
of the motor to turn and that provides the rotational motion to the wheels 102 to maneuver the body 101 over the surface and position in proximity to the pothole.

[0031] Upon positioning of the body 101, the microcontroller in association with a dust sensor integrated on the body 101 that works in synchronization with the imaging unit 103, detect level of the dust over the pothole. The dust sensor used herein is an optical dust sensor that comprises of a photo sensor and an infrared ray emitter, the infrared ray emitter emits the rays over the pothole and the photo sensor detects the reflected rays which are bounced back from the dust present over the pothole and based on the bounce back of the rays, the photo sensor determines the present of the dust and convert the determined data into electrical signal and sequentially transmits to the microcontroller.

[0032] The microcontroller processes the received data to determine the level of the dust over the pothole. A motorized disc 104 having multiple bristles 106 is installed with the body 101 by means of an L-shaped telescopically operated rod 105, wherein upon successful detection of the dust over the pothole, the microcontroller actuates the rod 105 to extend and position the disc 104 over the pothole in a manner that the bristles 106 are in contact with the surface of the pothole. The extension of the L-shaped telescopically operated rod 105 is powered by a pneumatic unit associated with the device that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of rod 105.

[0033] The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air. The air compressor is consisting of two main parts including a motor and a pump. The motor powers the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure. The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend. The piston is attached to the rod 105, wherein the extension/retraction of the piston corresponds to the extension/retraction of the rod 105 in order to position the disc 104 over the pothole.

[0034] Post positioning of the disc 104, the microcontroller actuates the disc 104 to rotate for scrubbing the pothole via the bristles 106. The motorized disc 104 rotates using a direct current (DC) motor integrated within the disc 104. The motor is coupled to the disc 104 via a drive shaft supported by ball bearings for ensuring smooth and efficient rotation. On actuation, the motor starts rotating and the torque is transferred to the disc 104 via the shaft, that causes the bristles 106 to rotate along with the disc 104 to dislodge dirt and debris from the pothole surface.

[0035] Synchronously, while the disc 104 rotates, the microcontroller actuates the wheels 102 for maneuvering the body 101 over entire pothole to ensure that the rotating bristles 106 of the disc 104 consistently sweep dust and debris across the entire pothole. This synchronized operation ensures that the entire pothole area is thoroughly cleaned and prepared for subsequent repair processes.

[0036] After removal of the dust and debris from the pothole, the microcontroller actuates an extendable L-shaped link 108 installed on the body 101 to extend and position a motorized drilling unit 107 integrated with the link 108, over the rocks and stones present in proximity to the pothole. The extension of the L-shaped link 108 is powered by the pneumatic unit associated with the device in the same manner as describe above for the L-shaped telescopically operated rod 105.

[0037] Post positioning of the drilling unit 107, the microcontroller actuates the drilling unit 107 for providing forceful hitting movement on the stones/ rocks in sync with the imaging unit 103 for breaking down the large rocks/ stones. The drilling unit 107 is used to drill cavity with the aid of drill bits. The drilling unit 107 comprises of a dc (Direct Current) motor, spindle, stepped pulley and drill bit such that when power is given to the motor the spindle rotates, and thereby the stepped pulley attached to it also rotates. On the other end, one more stepped pulley is attached and that is inverted to increase or decrease the speed of the rotational motion. The spindle moves up and down in the vertical direction in order to give the necessary amount of feed to the work and thereby aiding the drill bit in drilling the cavity over the stones/ rocks for breaking down the large rocks/ stones into smaller pieces.

[0038] A robotic link 109 is attached to the body 101 and integrated with a curved-shaped member 110 as an end-effector which is connected by means of a primary motorized ball-and-socket joint 111. The curved shape allows the member 110 to scoop out debris effectively from various depths and angles within the pothole. Once the stones or rocks within the pothole are broken into smaller pieces, the microcontroller actuates the robotic link 109 in synchronization with the primary motorized ball-and-socket joint 111 to scoop out smaller rock fragments, stones, and other loose debris from the pothole and transfer inside a waste vessel 112 mounted on the body 101.

[0039] The robotic link 109 mainly comprises of motor controllers, arm, end effector and sensors. The arm is the essential part of the robotic link 109 and it comprises of three parts, the shoulder, elbow and wrist. All these components are connected through joints, with the shoulder resting at the base of the arm, and connected to the microcontroller. The elbow is in the middle and allows the upper section of the link 109 to move forward or backward independently of the lower section. Finally, the wrist is at the very end of the upper arm and attached to the curved-shaped member 110 that is moved by the link 109 over the pothole.

[0040] Simultaneously, with the actuation of the robotic link 109, the microcontroller actuates the primary motorized ball-and-socket joint 111 for providing multi-axis rotational movement to the curved-shaped member 110. This multi-axis capability allows the curved-shaped member 110 to adjust orientation dynamically for accessing various angles and depths within the pothole for efficient scooping of debris, even from challenging or hard-to-reach sections of the pothole.

[0041] The primary motorized ball-and-socket joint 111 used herein is a mechanical component that connects the link 109 to the member 110. The ball and socket joint permits rotational and tilting movements, enabling the member 110 to rotate on its axis. The ball and socket joint are a coupling consisting of a ball joint securely locked within a socket joint, where the ball joint is able to move in a 360-dgree rotation within the socket thus, providing the required movement to the member 110. The ball and socket joint are powered by a DC (direct current) motor that is actuated by the microcontroller for providing multi-axis rotational movement to the member 110 in order to scoop out the smaller pieces of rock/ stones and excess debris from the pothole and transfer inside the waste vessel 112.

[0042] After the smaller pieces of rock/ stones and excess debris from the pothole are removed, the microcontroller actuates a vacuum based suction unit 125 installed on the body 101 for cleaning the left out dust/ debris and smaller particles. The suction unit 125 used herein consist of a suction pump, a hollow tube, and a receptacle 126 integrated with the suction unit 125 for extracting the dust/dirt from the pothole. The pump generates a negative pressure, creating a vacuum in the hose. The tube connects the pump to the receptacle 126, where the extracted dust/dirt is collected. Upon actuation of the suction unit 125 by the microcontroller, the pump creates a pressure differential, enabling the dust/dirt to travel through the tube and gets collected into the receptacle 126.

[0043] Once the pothole is properly cleaned as monitored by the dust sensor and the imaging unit 103, the microcontroller in association with an IR (Infrared) sensor provided on the body 101 and paired with the imaging unit 103, detect irregularities and dimensions of the pothole, respectively. The IR (infrared) sensor consists of two primary components: an infrared emitter (usually an LED) and an infrared receiver (a photodiode or phototransistor). The emitter emits infrared light towards the pothole. The light strikes the surface of the pothole and gets reflected off the surface of the pothole, which is detected by the receiver. The receiver detects changes in the reflected light and sends this data to the linked microcontroller in the form of electrical signals.

[0044] The microcontroller processes the received data from the IR (Infrared) sensor to detect irregularities and dimensions of the pothole. Based on the detected dimensions, the microcontroller evaluates the exact amount of mortar mixture required for filling the pothole effectively with the mortar mixture. By performing this evaluation, the device ensures optimal usage of resources, minimizing waste while achieving thorough and efficient repairs.

[0045] A multi-sectioned chamber 113 is housed within the body 101 and stored with various construction material required for pothole repair, such as cement, sand, and aggregate. Each section is designated for a specific material and is connected to a centralized mixing container 114 by means of a conduit 115 arranged between each of the section and container 114. These conduits 115 facilitate the transfer of materials between the storage sections and the mixing container 114.

[0046] Based on the evaluated amount of mortar mixture, the microcontroller actuates an iris lid 116 installed with each of the section to open up and release a regulated amount of the construction material into the conduits 115 that is further transferred to the container 114. The iris lid 116 mentioned herein, consists of a ring in bottom configured with multiple slots along periphery, multiple number of blades and blade actuating ring on the top. The blades are pivotally jointed with blade actuating ring and the base plate are hooked over the blade. The blade actuating ring is rotated clock and antilock wise by a DC motor embedded in ball actuating ring which results in opening/closing of the lid 116 for releasing the regulated amount of the construction material into the container 114.

[0047] Simultaneously, the microcontroller in association with a weight sensor installed with the container 114, monitor weight of the dispensed construction material. The weight sensor used herein is a particular kind of transducer, more especially a weight transducer, which transform a mechanical force that is applied as an input, by the weight of the construction material, into a change in electrical resistance, which varies proportionally to the force being applied to the sensor. This change in electrical resistance is detected by the microcontroller linked with the sensor, in the form of an electrical signal.

[0048] The microcontroller processes the received signals from the weight sensors in order to monitor weight of the dispensed construction material and as soon as the monitored weight matches with the evaluated amount, the microcontroller deactivates the iris lids 116 to stop further dispensing of the materials into the container 114.

[0049] After deactivating the iris lid 116, the microcontroller actuates a motorized stirrer 117 installed within the container 114 to mix the dispensed construction material to produce the mortar mixture. The motorized stirrer 117 consists of a rotating shaft attached to a DC (direct current) motor and fitted with multiple blades or paddles, which are positioned in a manner to cover the entire volume of the container 114. These blades are designed to mix the construction material. On actuation, the microcontroller regulates the movement of the motor followed by the movement of the blades for stirring/mixing the construction material to produce the mortar mixture.

[0050] Simultaneously, with the actuation of the stirrer 117, the microcontroller by means of a viscosity sensor installed within the container 114, monitor viscosity of the mortar mixture. The viscosity sensor used herein consist of a sensor element and a transducer. The sensor element interacts with the mortar mixture by moving through the mortar mixture. As the sensor element moves through the mortar mixture, it encounters resistance from the mixture viscosity. The transducer measures the force exerted on the sensor element due to this resistance and converts the measured force into an electrical signal. This electrical signal is further transferred to the linked microcontroller.

[0051] The microcontroller continuously processes the received signal in order to monitor the viscosity of the mortar mixture and compares the monitored viscosity with a pre-set threshold value of viscosity in the database of the microcontroller. As soon as the monitored viscosity matched with the threshold viscosity, the microcontroller deactivates the stirrer 117 and actuates an electronically controlled valve 118 arranged beneath the container 114 to dispense the mortar mixture in a pipe 119 lined with the container 114 in order to transfer the mixture over the pothole.

[0052] The electronically controlled valve 118 mentioned herein consists of a gate, nozzle and a magnetic coil which is energized by the microcontroller, on energizing of the magnetic coil, a magnetic force is generated which pushes the gate to open for dispensing the mortar mixture in the pipe 119 that is further transferred into the pothole for filling the pothole. After all the mortar mixture is dispensed from the valve 118, the microcontroller sends a command to de-energize the magnetic coil of the valve 118 in order to close the valve 118.

[0053] A box 120 is installed on the body 101 and stored with metallic rods, wherein during dispensing of mortar mixture over the pothole, the microcontroller actuates a robotic gripper 121 provided on the body 101 to grip and position the metallic rods within the pothole to ensure proper reinforcement and provide structural support to the pothole for enhancing the durability and longevity of the repair.

[0054] The robotic gripper 121 consists of actuators, sensors, and an end effector. The microcontroller processes input and controls the actuators, which are normally motors or pneumatics that move the gripper 121 fingers. The end effector physically interacts with the metallic rods and is responsible for gripping the metallic rod. Once the rod is gripped, the actuators move the fingers to securely hold the rod. The sensors detect the applied force, and the microcontroller adjusts the actuators to maintain a firm grip. After the rod is securely held, the gripper 121 further positions the rod into the pothole by moving its arm, using the actuators to precisely guide the rod within the pothole to ensure proper reinforcement.

[0055] An extendable bar 122 is installed on the body 101 and attached with a leveling plate 123 by means of a secondary motorized ball-and-socket joint 124. Post successful dispensing of mortar mixture over the pothole, the microcontroller actuates the bar 122 to extend in synchronization with the secondary ball-and-socket joint 124 to level the dispensed mortar mixture evenly. On actuation, the bar 122 extends and retract in a repetitive manner in order to provide swiping motion to the leveling plate 123 over the dispensed mortar mixture and the secondary ball-and-socket joint 124 adjust the position and angle of the plate 123 to ensure that the mortar is evenly spread and the surface is flush with the surrounding road surface.

[0056] During the pothole repair process, the microcontroller actuates the gripper 121 to grip construction flags from a storage unit 127 provided on the body 101 and position the flags around the pothole to serve as visual indicators of ongoing or completed construction work. The flags help to notify nearby vehicles and pedestrians regarding the ongoing work, thus ensuring safety and providing clear visual cues about the status of the repair site.

[0057] Post repairing of the pothole, the microcontroller activates a thermal camera 128 mounted on the body 101 to inspect temperature distribution of repaired road surface. The thermal camera 128 mentioned herein consists of a lens, detector array, and protocol. The lens focuses infrared radiation emitted from the road surface onto the detector array, which is made up of infrared sensors or thermopiles. These sensors convert infrared energy into electrical signals and send the data to the microcontroller. The microcontroller then interprets the temperature data to inspect temperature distribution of repaired road surface. For example, uneven cooling or unexpected hot spots in the thermal image might suggest that the mortar has not properly set or compacted in certain areas.

[0058] Upon detection of uneven heat patterns that are indicative of potential issues such as poor curing or improper compaction of mortar mixture, the microcontroller sends an alert notification on a computing unit (such as a smartphone, tablet, or other handheld devices) wirelessly linked with the microcontroller and accesses by a concerned authority. The computing unit is wirelessly associated with the microcontroller via a communication module which includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module.

[0059] The communication module allows the microcontroller to send and receive data to and from the computing unit without the need for physical connections. The Wi-Fi module provides connectivity over local networks, enabling real-time communication over longer distances. The Bluetooth module offers short-range, low-power communication, ideal for close proximity. The GSM module allows for communication over mobile networks, facilitating remote monitoring and control from virtually anywhere. This versatile connectivity ensures seamless interaction between the microcontroller and the computing unit for enabling the microcontroller to wirelessly send alert notification on the computing unit.

[0060] The microcontroller by means of a GPS (Global Positioning System) module integrated with the microcontroller, determine current location of the device. The GPS module comprises a GPS receiver, an antenna, and an internal processing unit that communicates with satellite signals to establish the precise geographic coordinates of the device. The antenna of the GPS module receives signals from multiple GPS satellites orbiting Earth, each transmitting unique timing and location data. The GPS receiver captures these signals and processes them to calculate the module's position using trilateration, a method that measures the distance between the module and at least three satellites. The processing unit converts this data into geographic coordinates (latitude and longitude), which are then sent to the microcontroller.

[0061] The microcontroller receives the coordinates data from the GPS module in the form of electrical signals to determine precise location of the device. Furthermore, the microcontroller is paired with a weather detection module, which continuously monitors real-time weather conditions such as temperature, humidity, and precipitation. This data is used to adjust the sensitivity of the device sensors (such as the dust sensor, LiDAR sensor or viscosity sensor) and the imaging unit 103, based on current environmental factors. For example, during rain, the sensitivity of dust or debris detection might be reduced, and adjustments might be made for optimal operation in wet conditions.

[0062] This integration allows for correlation analysis between detected anomalies, such as pothole dimensions or mortar mixture issues, and environmental factors like temperature or humidity. This results in more accurate, efficient, and reliable pothole repair operations, enhancing long-term maintenance efforts.

[0063] Lastly, a battery is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.

[0064] The proposed invention works best in the following manner, where the cuboidal body 101 is positioned over the ground surface via multiple motorized wheels 102 that provides translation to the body 101 as per requirement. In activation of the device the artificial intelligence based imaging unit 103 synced with the LiDAR (Light Detection and Ranging) sensor detect potholes and other visual anomalies of roadway. Also, the dust sensor works in synchronization with the imaging unit 103 for detecting level of the dust over the pothole. The GPS (Global Positioning System) module integrated with the microcontroller and the microcontroller is paired with the weather detection module to adjust sensitivity based on real-time weather data allowing for correlation analysis between detected anomalies and environmental factors to improve detection accuracy over time. Based on which the L-shaped telescopically operated rod 105 extend to position the motorized disc 104 with multiple bristles 106 over the pothole. Followed by which the disc 104 rotates for scrubbing the pothole via the bristles 106 in synchronization with actuation of the wheels 102 for maneuvering the body 101 over entire pothole for effectively sweeping dust and debris from the pothole. After which the extendable L-shaped link 108 extend/retract for positioning the motorized drilling unit 107 over rocks and stones present in proximity to the pothole. Followed by which the drilling unit 107 provide forceful hitting movement on the stones/ rocks in sync with the imaging unit 103 for breaking down the large rocks/ stones. Afterwards, the robotic link 109 via the curved-shaped member 110 scoop out the smaller pieces of rock/ stones and excess debris from the pothole and transfer inside the waste vessel 112. The vacuum based suction unit 125 clean the dust/ debris and smaller particles that are further stored inside the receptacle 126. Further, the IR (Infrared) sensor paired with the imaging unit 103 detect irregularities and dimensions of the pothole. Based on the detected dimensions the microcontroller evaluates the amount of mortar mixture required for filling the pothole with mortar mixture.

[0065] In continuation, the iris lid 116 of the multi-sectioned chamber 113 stored with construction material open up for dispensing the regulated amount of the construction material within the mixing container 114. The weight sensor monitors weight of the dispensed construction material and as soon as the monitored weight matches with the evaluated amount the iris lid 116 gets closed. Afterwards, the motorized stirrer 117 mixes the dispensed construction material to produce the mortar mixture. Simultaneously, the viscosity sensor monitors viscosity of mortar mixture and then the electronically controlled valve 118 dispense the mortar mixture over the pothole. During dispensing of mortar mixture over the pothole the robotic gripper 121 grip and position metallic rods within the pothole to ensure proper reinforcement. Further, the extendable bar 122 with the leveling plate 123 level the dispensed mortar mixture evenly for ensuring that repaired surface is flush with the surrounding road surface. During repairing of pothole, the microcontroller actuates the gripper 121 to grip construction flags from the storage unit 127 and position the flags around the pothole serving as visual indicators of ongoing/ completed construction work. Further, the thermal camera 128 inspects temperature distribution of repaired road surface.
