Autonomous Wall Painting Robot
Project Area of Specialization RoboticsProject SummaryAn autonomous wall painting robot will be designed which will be controlled via android application. The android app with specific features will also be designed in this project. The distance between the wall, robot will be selected via android app. Once the robot will reach its destination then signal will be provided to the controller for horizontal or vertical movement of sprayer stand via android app and sprayer will move horizontally or vertically according to user requirement. The distance moved by robot horizontally or vertically will be measured using IR sensor connected upper and lower bounds of the sprayer. Once the sprayer will be at right position then intensity of paint can be controlled via android app. The forward, backward, left and right movement od robot will also be controlled autonomously via android app
Project ObjectivesThe objectives of the project are to design a system for painting of wall which will be:
Autonomous
Efficient
User-friendly
Transportable
Cost-effective
Reduce strenuous and repetitive task
Increase safety
The Bluetooth module will be used to connect micro-controller with android application wirelessly. The arduino micro-controller will be used which will control the entire system in response to the instructions from the android app. DC motors will be used for forward, backward, left and right-side movement of the robot and these movements will be controlled via android app. The horizontal or vertical motion of spraying part, which includes sprayer gun, will be done via servo motors. The motion of spraying part will also be controlled via designed android app. Battery will be used as power supply in this project.
Benefits of the ProjectOur proposed project has higher efficiency and better productivity. It also has increased labors safety. Then the power consumption rate is very low. And in the project, we have also minimized the use of paint. Moreover, our unit have higher consistency. With its numerous benefits like quality control, repeatability, waste reduction, faster cycle times –automated painting could very well provide a way out. Concurrent upsides of automation include reduced labor costs and lower probability of blunders. These factors inspired the concept of an automated robotic painting system.
Technical Details of Final DeliverableArm Motion:
For the arm, the required motion is 2DOF, vertical motion and motion into the direction normal to wall surface. There are several solutions for such motion such as making a simple multi-link mechanism for the vertical linear motion. The normal motion can be made by the arm mechanism or through the base. The simple two link mechanism will be used but replacing slow stepping motors with fast dc servo motors.
Mobile Base:
The mobility requires fitting the arm on a mobile base, it is required to have 3 DOF as indicated that is two planar moving directions and one for rotation to adjust robot pose relative to the wall plane.
The Painting Feed Module:
A standard commercial module is used that make automatic painting fluid feed to the roller. The responsibility of ensuring enough amount of painting fluid and controlling its color is left for the human user at this stage, though it can be improved in the future to generate some messages for the user when the fluid is below the limits. The feed painting mechanism works on a supply of DC voltage and pumps the liquid through a hose to the roller.
The Graphical User Interface:
The user interface should be made graphical for ease of use especially for non-technical users. An android application will be designing for controlling wall painting robot autonomously. The major requirements of the interface are to:
Options for forward, backward, left and right movement of robot.
Option for stopping robot.
Option for horizontal or vertical motion of the robotic arm.
2. Option to set the painting speed for considerations related to quality and paint viscosity.
5. Option to stop painting for roller cleaning or paint refill.
