[0022] Referring to Figure 1, an isometric view of a wall corner crack filling device, is illustrated, comprising a rectangular base 101 having four motorized omnidirectional wheels 102, an L-shaped telescopic arm 103 attached to a front edge of the base 101 by a hinge 104, an L-shaped telescopic link 105 attached with the base 101 by a primary ball and socket joint 106, having a motorized brush 107 at the end, a rigid inverted U-shaped flap 108 attached on the base 101, a sliding unit 109 on an upper periphery of the flap 108, an L-shaped telescopic rod 110 having a nozzle 111 at an end of the rod via a conduit 112, an L-shaped telescopic member 113 having paint roller 114 attached on the base 101 by a secondary ball and socket joint 115 an artificial intelligence-based imaging unit 116 installed on the base 101, a speaker 117 provided on the base 101, a microphone 118 provided on the base 101, and a touch-enabled display panel 119 provided on the base 101.

[0023] The proposed device comprises of a rectangular base 101 having four omnidirectional motorized wheels 102 for a locomotion of the base 101. Each of the wheels 102 are actuated by a microcontroller to rotate the wheels 102 for locomotion of the base 101. Each of the wheels 102 are coupled with a DC (Direct Current) motor that is activated by the microcontroller to provide circular motion to the wheels 102. The working principle of a DC motor is based on the interaction between a magnetic field and an electric current. When an electric current flows through the coil of wire, also known as the armature, it creates a magnetic field. This magnetic field interacts with the fixed magnets, known as the stator, causing the armature to rotate. The rotation is achieved by reversing the direction of the current flow in the armature coil using a commutator and brushes that provide continuous movement of the motor results in providing circular motion to the wheels 102 for locomotion of the base 101 as per requirement.

[0024] Further, an L-shaped telescopic arm 103 having a triangular plate at the end attached to a front edge of the base 101 by a hinge 104 for scraping the wall corner. The telescopic arm 103 is equipped with a pneumatic unit that is activated by the microcontroller to provide extension and retraction of the arm. The pneumatic unit comprises of an air compressor, air cylinder, air valves and piston. The air valve that allows entry or exit of the compressed air from the compressor. Furthermore, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the cylinder and due to the increase in the air pressure, the piston extends due to which the arm 103 extend to position the plate in proximity of the wall corner for scraping.

[0025] Herein, the hinge 104 assists the arm to move the plate at the corner for scrapping the corner. The hinge 104 typically refers to a mechanical joint that allows rotational movement around a fixed axis using a motor or actuator which provides the rotational force required to move the hinge 104. The motor is typically controlled by an electronic control unit that regulates its speed and direction. The hinge 104 consists of a hinge mechanism that enables rotation around a fixed axis. It usually consists of two parts: a stationary component and a moving component. The stationary component is securely attached to one part of the arm, while the moving component is connected to the plate that needs to rotate the plate for scrapping the corner of the wall as per requirement.

[0026] Further, an L-shaped telescopic link 105 having a motorized brush 107 at the end attached with the base 101 by a primary ball and socket joint 106 for a cleaning of the wall corner. The link 105 is equipped with the pneumatic unit that is activated by the microcontroller to provide extension and retraction of the link 105 to position the brush 107 at the corner of the wall. The brush 107 is coupled with a motor that is activated by the microcontroller to rotate the brush 107 with specified speed in order to clean the corner of the wall.

[0027] Herein, the ball and socket aids the brush 107 to clean the entire corner of the wall. The ball and socket joint 106 is a mechanical arrangement consists of a ball-shaped component that fits into a socket, with a motor providing the necessary power to drive the rotation to provide angular movement to the brush 107 in a manner that brush 107 move all around the corner to clean the wall corner.

[0028] Further, a rigid inverted U-shaped flap 108 having a sliding unit 109 on an upper periphery of the flap 108 for translating an L-shaped telescopic rod 110 having a nozzle 111 at an end of the rod installed with the sliding unit 109. The sliding unit 109 comprises of a rail unit that provides a guided path for linear movement. The rail unit usually includes a pair of parallel rails or tracks, along which the sliding unit 109 moves. The slider carriage, also called a stage or platform equipped with a mechanism to minimize friction and ensure smooth motion. This involves the use of ball bearings. The sliding unit 109 incorporates a motor and a drive mechanism to generate linear motion. The motor is connected to a drive mechanism, such as a belt, lead screw, or ball screw. The drive mechanism converts the rotational motion of the motor into linear motion, propelling the slider carriage along the rail unit to translate the telescopic rod 110 as per requirement.

When an electrical current flows through the coil, it interacts with the magnetic field produced by the magnet assembly, resulting in a force that moves the coil. The magnet assembly creates a magnetic field within the speaker 117. It consists of a permanent magnet and a metal structure, such as a pole piece or a magnet plate. The magnet assembly provides a fixed magnetic field through which the voice coil moves. The strength and configuration of the magnet assembly influence the performance and efficiency of the speaker 117.

[0033] The cone/diaphragm is connected to the speaker 117's frame via a suspension unit, which includes the surround and spider. When the electrical signal passes through the voice coil, it generates a magnetic field that interacts with the fixed magnetic field produced by the magnet assembly. As the electrical current varies, the magnetic field produced by the voice coil changes, resulting in the voice coil and attached cone/diaphragm moving back and forth. This movement creates pressure variations in the surrounding air, generating sound waves to generate the audible sound to notify the user regarding the refilling of the tank.

The AI protocols are used to process and analyses the images captured by the camera enabling it to perform various tasks beyond traditional image capturing. The AI analysis is performed locally on the camera itself and the real-time processing on the camera enables immediate responses and faster decision-making.

[0036] The camera, herein captures images in a vicinity of the base 101 with the help of specialized lenses designed to capture high-quality visuals. The captured data is now pre-processed via the processor to enhance its quality and prepare it for AI analysis. This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information present in the images.
