AN AUTOMATED SYSTEM FOR WALL PAINTING
FIELD OF INVENTION
[0001] The embodiments herein generally relate to wall painting sector. More particularly, the invention relates to an automated system for wall painting. BACKGROUND AND PRIOR ART
[0002] Painting on tall walls appears to be a greater challenge for the painters. Apart from the attempt of taking risk by the painter regarding height of the walls, there are several side effects caused by direct exposure to paint. Inhaling paint fumes exacerbate asthma and sinusitis, says Dr Keith Prowse, of the British Lung Foundation. Meanwhile, in Denmark, specialists have identified a neurological condition brought on by long-term exposure to paint solvents — 'painter's dementia'.
[0003] Professional painters are most at risk as they have a 20 per cent increased risk of a range of cancers, particularly lung cancer, according to the World Health Organization. Manual labor cost is very high and time consuming can take 5-6 days for a single space. Getting paint on the skin can also lead to an allergic, rash-like reaction, says consultant -dermatologist Dr Andrew Wright, of Bradford Teaching Hospital Trust and men regularly exposed to the chemicals in paint may be more prone to fertility problems, suggests a study from Sheffield and Manchester University. Additionally, Painting accidents have increased a lot, falling from heights and slipping.
[0004] Currently, many researchers have worked on and had come up with wall painting robots, systems employing drones, robotic hands, suspended robotic hands, wheeled robots with robotic hands. But, there is no robotic system

solving the problem of painting at heights even though researcher's have implemented techniques by using framed robot for up to 5m height devouring tall buildings has always been a tedious task to conquer and could only be done with human labor.
[0005] Most of the implemented systems are wheeled robots with robotic hands or otherwise a frame suspended robot using spray painters; but the time of completion of work and the efficiency of said robot with spray painters is very less even when compared to a human counterpart. Using spray painting method over exterior wall coating is not preferred by painting experts as a certain level of thickness and texture to the paint is required.
[0006] Therefore there is a need to develop an automated system for wall painting that marginally reduces human casualties and labour and allows to conquer heights that are humanely difficult to pull-off and simultaneously paints the surface or wall without compromising the finishing.

[00047] Tall wall painting robot (automated system) 100 capable of climbing vertically a rope or gripped strip or a gear strip 106 using a gear lock mechanism (rack pinion gear system) or gear strip locking mechanism 104 or rope climbing mechanism and paint the surface using paint applicator for which the paint is supplied by the dispenser module 102 from the onboard reserve tank. [00048] The Climbing mechanism uses stepper motors and circular gear rotors or rack and pinion gears or sprockets or gripped rubber rotor or spur gear system to rotate in step cycles and hold on climb track.
[00049] According to an embodiment, the gear strip locking mechanism 104 is attached to a front portion of the first plate 103. According to an embodiment, the dispenser module 102 along with the paint applicator 116 is attached to the back portion of the first plate 103 using a connector. The gear strip locking mechanism 104 is configured for allowing the automated system 100 to move in upward-downward direction along the wall and thereby allowing the paint applicator 116 to paint the required area of the wall by moving in upward-downward direction along the wall.
[00050] According to an embodiment, the user interface controller configured to set required paint thickness and area of the wall for painting. [00051] According to an embodiment, the onboard paint pumping system pumps paint from the onboard reserve tank into the dispenser module 102. The onboard reserve tank is provided for storing the paint.
[00052] According to an embodiment, the microcontroller is configured for controlling the stepper motors system based on user input; wherein said user input includes move upwards, downwards, ON pump and OFF pump. [00053] According to an embodiment, the linear actuator system 115 is provided with a screw system at back end of the dispensing module 102. The linear actuator system 115 is configured to maintain the paint applicators 116 pressure against the

wall by varying linear alignment of said paint applicator 116 from the automated system using screw system.
[00054] According to an embodiment, the dispenser module 102 is specially designed and configured to evenly wet the paint applicator 116 with the paint. The dispenser module 102 is provided with a perforated semi-circular tubing system and configured to serve as a support module providing a grip to the paint applicators 116 and thereby evenly spreading the paint over the pain applicators. The dispenser module 102 is further configured to act as an excess paint collector. The paint applicator 116 is a porous roller through which paint is released and evenly spread throughout the roller fibres along the required area of the wall. [00055] The rollers (also referred as paint applicators) 116 and dispenser module 102 paints the surface evenly by controlling the amount of paint dispensed and using linear actuator system 115, screw system to adjust distance from wall and robot 100 to maintain pressure against wall.
[00056] According to an embodiment, onboard sensor systems are provided for tilt sensing, laser alignment from wall and base, paint and battery levels, obstacle sensing and edge sensing. Further, paint pumping and electrical supply system are provided at the base of the building that includes but not limited to high altitude paint pump, paint tank and power supply.
[00057] The automated system 100 starts the set of stepper motor system to climb over the rack 106 and the linear actuators 115 press the rollers to the wall to evenly coat the wall with paint. The automated system 100 reaches the maximum height of the building and comes back down coating the walls with perfect layer of paint evenly. Any wastage or spill of paint in the dispenser module 102 is pumped back into the onboard reserve tank in real time operation. The linear actuator system 115 release the pressure against the wall and are withdrawn. The automated system 100 is detached from the rack cord 106 and the rack cord 106 are detached from the top and base modules. [00058] The dispenser module 102 and the tank are removed for cleaning ones the

painting is finished. The whole system or automated system 100 is either controlled by a mobile application or works in fully autonomous mode after assembly.
[00059] Fig. 2 illustrates an exemplary model of a front view of the automated system for wall painting, according to an embodiment of the present invention. A backup paint reservoir is placed towards the back to ensure a constant supply of paint to the dispensers. Autonomous painting mode is suitable for horizontal and vertical motion. After assembling the robot (automated system) 100 to the rope 106 (rack) and closing sliders, the paint thickness and levels are entered through the user interface controller then the robot 100 autonomously starts wetting the rollers 116 and then start linear actuator system 115 to press the rollers 116 to the wall and starts climbing while painting the wall evenly. A full cycle of up and down motion will cover the entire area with paint.
[00060] Fig. 3 illustrates a rack pinion gear system 102 of the automated system for wall painting, according to an embodiment of the present invention. The gear strip locking mechanism 104 includes a rack and pinion mechanism, a linear railing system 107 and a stepper motors system. According to an embodiment, the rack and pinion mechanism includes a double sided rack chord 106 and at least four pinion gears 105. According to an embodiment, each pair of pinion gears 105 are placed on both sides of the rack chord 106 and the rack chord 106 is coupled with the pinion gears 105. The stepper motors system is attached to a back end of the pinion gears 105 and provided for running the rack and pinion mechanism for precision. The rack and pinion mechanism is configured for converting rotatory motion into linear motion and thereby facilitating the vertical upward-downward motion of the automated system 100.
[00061] According to an embodiment, the rack cord 106 is fed into the gear system 105 and a distance alignment system is used to make the automated system 100 parallel to the horizontal plane. The rack cord 106 is fastened to a base module and a top module which also functions as a system for traversing the

horizontal plane by using track mechanism. According to an embodiment, the horizontal base and top track system is then used to align the system to the next vertical coating layer and the process is repeated till the required area of wall is fully covered with paint. The horizontal motion is based on automated track wheel mechanism with counter weight or suspending using wheeled crane or gear track mechanism.
[00062] The gripped rollers (rack and pinion) 105 attached to the gripped rope 106 is used in climbing motion for stability and accuracy. The arrangement of rack and pinion gear mechanism increases the load capacity of the automated system 100 and also results in a stable linear motion on the rack chord 106. Gear backlash is reduced significantly with the provided configuration of rack 106 and pinion 105. The semi-circular paint dispensers 102 wet the rollers 116 and the linear actuator system 115 press the rollers 116 to the painting surface and ensure an even coat of paint on the surface.
[00063] The automated system 100 achieves vertical motion by using a rack cord 106 climbing mechanism wherein a system of four stepper motors with gripped gear system is attached to gripped rack cord. A stepper motor or step motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position is commanded to move and hold at one of said steps without any position sensor for feedback as long as the motor is carefully sized to the application with respect to torque and speed. The two motors that are attached to the gripped rope wherein one rotates in clockwise and the other in anticlockwise direction, the friction generated helps the robot 100 achieve the vertical motion. [00064] Fig. 4 illustrates an exemplary model of an exploded view of the linear railing system for wall painting, according to an embodiment of the present invention. According to an embodiment, the linear railing system 107 is attached to the rack chord 106 and configured to allow a smooth and stable vertical upward-downward motion and to cancel out horizontal motion with respect to plane. Further, the linear railing system 107 includes a track 108, a slot 109 and a

fixing top 110. The linear railing system 107 guides the rack chord 106 through the slot 108 and thereby aligning and fitting the rack chord 106 in exact position avoiding slip or misalignments.
[00065] According to an embodiment, the slot 109 includes a fixed screw configuration 111 provided periodically and protruding outward along the length of the track. According to an embodiment, the fixing top 110 provided with circular holes 112 in middle matching the fixed screw 111 configuration of the slot 109 for proper alignment.
[00066] According to an embodiment, the second plate 114 is provided with control boards and the second plate 114 is fixed to the linear railing system 107 using the fixing top 110 and by guiding the circular holes 112 of the fixing top 110 through the fixed screw configuration 111 and tightening the fixed screws 111 with a bolt 113.
[00067] The automated system 100 includes two pairs of stepper motors along with two pumps which are all Bluetooth controlled. According to an embodiment, Arduino Mega 2560 receives a character from the user via the Bluetooth HC -05, which is stored in a variable and passed through a switch case(). Depending on the variable received switch case is activated. The switch case contains the functions that includes but not limited to move upwards, move downwards and stop, ON the pump and OFF the pump.
[00068] When the function is move upwards, herein the first pair of stepper motors, the first motor moves in a clockwise direction and the second motor moves in an anti-clockwise direction. The same process happens for the second pair of stepper motors simultaneously along with the first pair of stepper motors. When the function is move downwards, here in the first pair of stepper motors, the first motor moves in anti-clockwise direction and the second motor moves in clockwise direction. The same process happens for the second pair of stepper motors simultaneously along with the first pair of stepper motors. When the function is stop, here both the pairs of stepper motors stop rotating and the robot

stops. When the function is ON the pump, the pump is switched ON via the relay to pump the paint to the roller, so that the painting is done. When the function is OFF the pump, the pump is switched OFF via the relay to stop pumping of the paint to the roller. The stepper motors have a lot of advantages when compared with other motors like DC motor and servo motors. The rotation angle of the stepper motor is proportional to the input pulse. The stepper motor has full torque at standstill. A wide range of rotational speeds are realized as the speed is proportional to the frequency of the input pulses. PWM is a technique for creating a digital square wave signal. For a stepper motor, a full rotation is divided into number of steps. A stepper motor driver is used to power the stepper motor and simplify the control into steps and direction pulses.
[00069] The stepper motor driver expects a series of input pulses to move the motor to any given angle. The driver moves the motor one step for each input pulse and a delay is provided to create the necessary square wave required to input to the motor driver. The pump is connected to a relay. A Relay is controlled by low-voltage control signal from Arduino (5 volts) and is capable of handling and switching high-voltage or high-power circuits. The 5 volts from the Arduino energizes the electromagnet of the relay which in turn causes the switch to open and close, hence controlling the working of a pump. The system works in a fully automated or can be controlled by a Mobile application via Bluetooth. [00070] Fig. 5 illustrates a linear actuator system 104 of the automated system for
wall painting, according to an embodiment of the present invention herein. A
semi-circular dispenser module 102 with the tube system and with perforation on the surface of the tube is used for evenly wetting the rollers and reducing wastage of paint. The linear actuator system 115 are used to press the rollers 116 against the wall, and the vertical motion of the robot 100 helps to evenly spread the paint on the rollers 116 and then to the walls. The onboard sensor systems include real time monitoring of the alignment using laser distance measuring, paint level and battery level indicators, paint thickness settings in user interface controller. The

user interface controller is further configured for controlling the paint dispenser
valve to attain proper texture.
[00071] Fig. 6 illustrates an exemplary model of a back view of an automated
system for wall painting, according to an embodiment of the present invention
herein. The paint applicator 116 is a porous roller through which paint is released
and evenly spread throughout the roller fibres along the required area of the wall.

system for wall painting marginally reduces human casualties and labour.
[00073] Another advantage of the present invention is that the provided
automated system for wall painting conquers heights that are humanely difficult to
