Final Project Proposal

Project Ideation

1- Tell us about the purpose of your project. Which problem does it solve? Why do you care about this? What were you inspired by? Include images and videos of similar projects

DOPABOT

Happiness maker

Handwriting and hand drawing activates the Brain, boost Creativity, and add life to the content compared to computerized writing. Drawing created by pen increases memory and retention of feelings. The message Writing by hand can improve mood and give a sense of well-being—putting pen to the page helps flesh thoughts out in an orderly manner, leading to burdens feeling lighter. For the past few years, robotics technology used for efficiency, welfare, and saving time and money. Thus, the robotic plotter offers the combination between new technology and old-fashioned pen and paper has an immense impact on emotional well-being, helping us organize our thoughts and even improve our moods.

Finally, the pen drawing robot, in which we mixed art with technology, to help you in capturing the unique moments, and boost creativity.

2D Pen Plotter

The goal of this project is to fabricate a simple and low-cost drawing robot with the minimum parts possible that can produce some very good quality drawings. Also, it can be used to draw on t-shirts, phone covers, make decorations, and so on.

The DOPABOT is a Wireless Pattern Making Robot that offers the fastest way to powerfully produce drawings as shown in the figure.

2- Describe the project idea and general features. How would it work?

The brain of DOPABOT is an Arduino UNO board in combination with stepper motor drivers and two stepper motors for the arm and one for the drawing plate.

The 3D printer will be used to print construction parts of the robot and laser machine for cutting and engraving the base of the component.

Mathematical relations and patterns are found all around us in our daily lives as well as in nature. These patterns can range from simple to complicated and harmonious to chaotic. In this project we hope to develop a Arduino Powered Pattern Making Robot to make beautiful patterns and discover the relation between mathematics and art through patterns. wherein the robot designs or sketches the input is given from the computer on the drawing board or a sheet of paper using Arduino UNO.

Project Planning

4- Describe the Technical Modules that your project consists of

Construction Parts

The main Construction components are

The motion for the arm axes is provided through two stepper motors. A stepper motor will be used to rotate the drawing plate.
Parts of the robot arm, pen holder,and coupling will be printed using 3D printer.
The robot enclosure will be used for mounting the stepper motors, Arduino, and other electronic components, it will be cut and engraved using the laser cut machine.

Input

(Sensing, Tactile Input, and/or Graphical Input)

codes and tell the robot what pattern to do. To select the pattern, the mobile app based on Serial Bluetooth Module (HC-05 module) has been used. numbers from 1 - 4 used for the pattern and 5 for the end of the drawing.

Action

(Physical and/or Graphic)

Two NEMA 17 stepper motors provide the motion of the arm axes, which control the up and down movement of the marker pen. One stepper motor to rote the drawing plate. Then the marker pen sketches the pattern on board.

Brain

an Arduino Uno board in combination with three A4988 stepper drivers.

Power Management

For powering the robot, we need Wall Adapter Fixed 9V 2A DC for powering most electronic devices , and the Arduino UNO

5- Create a cardboard prototype of your project, demonstrating the project face as well as internal movements and mechanisms. Include a demo video and photos of the prototype.

6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.

Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish

Minimum User Features

Creating programmable simple pattern drawings
- Action: stepper motors
- Sensing: Non
- User Input: Serial bluetooth module based mobile app

Complete User Features

Creating advanced pattern drawings for lines and engineering shapes use Arduino code to controlling plotters.
- Action: stepper motors
- Sensing: None
- User Input: Serial bluetooth module based mobile app

Nice-to-have User Features

Making the machine draw almost anything by Plotter with the cool feature is automatic tool change. In other words, the machine will be able to automatically change colors, so we can draw cool stuff with it. Thus, the machine can produce very detailed color drawings for t-shirts, cake decorations. Also use it to draw out scale drawings, wedding invitations, birthday cards, and anything else you can think of. :)
- Action: stepper motors and micro servo motor
- Sensing: Non
- User Input: images or graphics.
