[0020] The present invention relates to a cement wall finishing device that is capable of finishing a cement wall by scrapping the wall surface with appropriate application of force in addition with providing a smooth surface to the wall without any application of physical efforts in operating the devices thus prevent chances of error in finishing the wall surface.

[0021] Referring to Figure 1, an isometric view of a cement wall finishing device is illustrated, comprising a frame composed of a pair of elongated rectangular primary plates 101 arranged in an X-shape, the X-shape is reinforced on four sides by four elongated rectangular secondary plates 102, ends of the primary plates 101 provided with clamps 103, four telescopic rods 104 attached underneath the frame, ends of the rods 104 provided with motorized omnidirectional wheels 105, a pair of telescopic links 106 attached on top of the frame by means of ball and socket joints, a metal wire 107 connected between upper ends of the links 106, one end of the wire 107 spooled in a roller 108 attached with one of the links 106, an artificial intelligence-based imaging unit 109 installed on the frame, a cuboidal platform 110 attached on the frame by means of pneumatic actuator, a speaker 111 installed on the base, an LDR (light dependent resistor) 112 provided with the frame, multiple LEDs (light emitting diodes) 113 mounted on the frame, a microphone 114 provided on the frame, and a touch-enabled display 115 provided on the frame.

[0022] The proposed device comprises of a frame encased with various component associated with the device arrange in sequential manner that aids in finishing cement wall. Herein, the frame is composed of a pair of elongated rectangular primary plates 101 arranged in an X-shape reinforced on four sides by four elongated rectangular secondary plates 102 and ends of the primary plates 101 integrated with clamps 103 by means of linear actuators for anchoring of the frame in a position. Upon anchoring the frame, the user requires to activate the device manually by pressing a push button integrated on the frame. The button is type of a 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.

[0023] After activating of the device by the user, a microcontroller associated with the device generates a commands to operate the device accordingly. Upon activating the device, the microcontroller activates a microphone 114 integrated with the frame to give voice commands regarding finishing a cement surface. The microphone 114 receives sound waves generated by energy emitted from the voice command in the form of vibrations. After then, the sound waves are transmitted towards a diaphragm configured with a coil. Upon transmitting the waves within the diaphragm, the diaphragm strikes with the waves due to which the coil starts moving the diaphragm with a back-and-forth movement in presence of magnetic field generated from the coil.

[0024] After that the electric signal is emitted from the coil due to back-and-forth movement of the diaphragm which is further transmitted to the microcontroller linked with the microphone 114 to process the signal to analyze the signal for detecting voice command given by the user. Upon processing the voice commands, the microcontroller actuates an artificial intelligence-based imaging unit 109 synced with a laser sensor integrated in the frame to detect dimensions and unevenness of a cement wall surface. The imaging unit 109, disclosed herein comprises of a camera and processor that works in collaboration to capture and process the images in a vicinity of the frame. The camera firstly captures multiple images of the vicinity of the frame, wherein the camera comprises of a body, electronic shutter, lens, lens aperture, image sensor, and imaging processor that works in sequential manner to capture images of the vicinity of the frame.

[0025] After capturing of the images by the camera, the shutter is automatically open due to which the reflected beam of light coming from the surrounding due to light is directed towards the lens aperture. After then the reflected light beam passes through the image sensor. The sensor now analyzes the beam to retrieve signal from the beams which is further calibrate by the sensor to capture images of the vicinity of the frame in electronic signal. Upon capturing images, the imaging processor processes the electronic signal into digital image. When the capturing is done, the processor associated with the imaging unit 109 processes the captured images by using a protocol of artificial intelligence to retrieve data from the captured image in the form of digital signal. The detected data is now transmitted to the microcontroller based on which the microcontroller acquires the data to detect the presence and dimensions of cement wall surface.

[0026] Upon detecting the dimensions and presence of the wall surface, the microcontroller generates commands to actuate a pneumatic unit integrated with each of four telescopic rods 104 attached underneath the frame to extend and retract as per relative commands generated by the microcontroller. The pneumatic unit comprises of an air compressor, air cylinder, air valves i.e. Inlet and outlet valve and piston that works in collaboration to aid extension and retraction of the rods 104. The air compressor is coupled with a motor that gets activated by the microcontroller to compress the air from surroundings upon entering from the inlet valve to compressed and pumped out via the outlet valve.

[0027] The air valve 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. And upon closing of the valve, the compressed air exit out from the cylinder thereby decreasing the air pressure of the cylinder. The increasing and decreasing of the air pressure from the cylinder aids in extension and retraction of the piston that turns in aiding extension and retraction of the rods 104. Simultaneously, the microcontroller actuates a motorized omnidirectional wheel integrated with each of the rods 104 to move the frame in proximity of the wall surface. The wheel is coupled with a motor that is activated by the microcontroller to provide circular motion to the wheel to move the frame in proximity to the wall surface.

[0028] Upon positioning of the frame in proximity of the wall surface, the laser sensor detects the unevenness of the wall surface. The laser sensor sends laser beams at two points of the wall surface to form a triangle between the wall surface and the point of the laser sensor from where lasers are emitted. The beams are bounced back towards the sensor and are sensed by the sensor with the angle formed between the emitting point and the surface at which laser beam are impact. The laser sensor, after detecting the required data of area of the wall surface sends the data to the microcontroller. After receiving data, the microcontroller analyzes the data to detect the unevenness in the wall surface.

[0029] Upon detecting the unevenness of the wall surface, the microcontroller actuates a pneumatic unit integrated with a pair of telescopic links 106 attached on top of the frame to extend and position a metal wire 107 connected between upper ends of the links 106 in contact with the wall surface. After that the microcontroller actuates a ball and socket joint integrated with each of the links 106 to move the link in sequential manner to scrap the cement for finishing the wall surface along with extending of the wire 107 as per detected dimensions of the wall surface via a roller 108 coiled with the wire 107 attached with one of the links 106. The ball and socket joint 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 links 106 in sequential manner to scrap the cement for finishing the wall surface along with extending of the wire 107 from the roller 108 for scraping of cement for finishing the wall surface.

[0030] During scraping of the wall surface, a cuboidal platform 110 is assembled on the frame by means of pneumatic actuator to allow the user to stand on the platform 110 for supervising work. Upon standing over the platform 110, the user accesses a touch-enabled display 115 provided on the frame to provide touch input regarding raising or lowering the platform 110. The display 115 works by using LCD (liquid crystals) that are manipulated by electric currents to control the passage of light through the display 115. When an electric current is applied, the liquid crystals align in a way that either allows light to pass through or blocks it, creating the images and colors that is being visible in the LCD of the display 115 panel regarding the raising or lowering the platform 110 that is further change the electric charge at the location of the touch by the user to register as input. The input is stored in the microcontroller to process the input.

[0031] Upon processing the input given by the user, the microcontroller actuates a pneumatic unit integrated with the pneumatic actuator to provide extension and retraction of the actuator to raise or lower the platform 110 for supervising the work of scraping of the wall surface. Herein, a weight sensor embedded in the platform 110 detects a weight of the user on the base. The weight sensor comprises a weight transducer that convert weight of the user into an electrical signal that exert a downward force on the weight sensor. Within load cell of the sensor, there are strain gauges that deform slightly due to weight. The deformation causes changes in electrical resistance within the strain gauges. The sensor then calibrates the resistance to detect the weight of the user stand on the platform 110. Upon detecting the user’s weight, the sensor transmitted the data to the microcontroller where it analyze to detect the weight of the user stand on the platform 110.

[0032] Based on detecting the weight of the user, if the microcontroller finds the detected weight exceeding a threshold weight, then the microcontroller actuates a speaker 111 installed on the platform 110 to notify the user to warn the user regarding an overload condition. The speaker 111 includes a diaphragm, which is typically made of a lightweight and rigid material like paper, plastic, or metal to vibrate and produce sound waves when electrical signals are fed to it for notifying the user. After passing of the electrical signal through a voice coil suspended within a magnetic gap of the speaker 111, it generates a magnetic field that interacts with the fixed magnetic field produced by a magnet assembly associated with the voice coil. Upon variation in electrical current, 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 overload condition to stay away from the platform 110 to prevent damage of the platform 110.

[0033] Additionally, an LDR (light dependent resistor) 112 assembled with the frame detects an ambient light in surrounding of the wall surface. The LDR 112 works on a principle based on photoconductivity. When the light of the surrounding falls on the LDR 112, then the electrons in the valence band of the materials within the surrounding are desired to the conduction band. The jumping of electrons from the valence band to the conduction band detect the intensity of the light. If less electrons are desired to jump in conduction band, then the detected intensity is less. After then the LDR 112 sends the detected intensity data to the microcontroller to analyze to detect the light intensity of the surroundings.

[0034] Upon detecting intensity of light in the surroundings, the microcontroller matches the detected intensity with a threshold light level pre-fed in database of the microcontroller. If the detected intensity recedes the threshold light level, then microcontroller activates multiple LEDs (Light Emitting Diodes) 113 installed over the frame for illuminating light to increase light intensity in surroundings. The working principle of LED 113 is based on electroluminescence activated by the microcontroller leads to generate photons in the form of energy by recombined holes and electrons. The recombination process includes jumping of the electrons from conduction bands to valance bands that aids to release energy in the form of thermal lattice vibrations known as photons that aids to glow the light in the surroundings to maintain appropriate visibility in surrounding of the wall surface to maintain proper scraping of the wall surface in order to provide proper surface finishing.

[0035] Additionally, the user accesses a computing unit associated with the device to provide input regarding tracking location of the frame. The computing unit includes but not limited to a mobile and laptop that comprises a processor where the alert received from the user is stored to process and retrieve the output data in order to display 115 in the computing unit. The microcontroller is wirelessly linked with the computing unit via a communication module which includes but not limited to Wi-Fi (wire 107 less Fidelity) module, Bluetooth module. GSM (Global System for Mobile communication). The communication module acts as a medium between various electronic unit for establishing communication between the computing unit and device to process the input.

[0036] Upon processing the input given by the user, the microcontroller generates commands to actuate a GPS (Global Positioning System) module integrated with the microcontroller to retrieve exact location of the frame. The GPS sends the signals of the detected location of the platform 110 to the satellite and after then a controller process that signal to analyze the location coordinates of the frame. Further, that data of coordinates are sent back to the GPS module where the microcontroller analyze that coordinates data to sends the data in the form of alert in the computing unit to track the location of the frame during wall surface finishing operation.

[0037] A battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so the user effectively carry out their appropriate functions.

Further, the four telescopic rods 104 provided with motorized omnidirectional wheels 105 for a locomotion of the frame. Herein, the user accesses the microphone 114, linked with the microcontroller, to give voice commands regarding finishing a cement surface to trigger the microcontroller to actuate the imaging unit 109 in synchronization with the laser sensor to determine dimensions and unevenness of a cement wall surface to actuate the ball and socket joints and the links 106 to scrape the wall for providing a smooth surface to the wall. After that the user accesses the touch-enabled display 115 for giving input regarding raising or lowering the platform 110, to actuate the pneumatic actuator to extend or retract to raise a lower the platform 110
