Week1: Requirement Analysis, Timeline Assignment and Hardware Verification

 Requirement Analysis and Verification


Software  

The main challenge is that the Etch A Sketch can only draw patterns in a single continuous stroke. The software focuses on image processing and conversion.  

    - Develop software to process an image into a format suitable for the Etch A Sketch.  
    - Convert the image into a standardized format, such as G-code.  
    - Implement software on Arduino to:  
      - Read serial commands  
      - Parse parameters  
      - Generate motion instructions  
      - Send pulse signals to control the motors  

Hardware  

Since most of the functionality is handled by software, hardware requirements are kept minimal.  

    - Design a circuit using an Arduino Uno and a motor driver to receive instructions and send control signals.  
    - 3D print a frame to attach the motor to the Etch A Sketch board.  
    - 3D print connectors to link the motor bearings with the Etch A Sketch knobs.  

Activities  

    - Assembled a half circuit using one motor driver and an Arduino to verify functionality.  
    - Tested the motor operation using the Arduino and motor driver.  
    - Designed 3D-printed connectors and a bracket mount.  
    - Ordered 3D-printed parts for final assembly.

Etch A Sketch Robot: Overview

Image
Overview This is a University of Liverpool Year 2 project . Our project explores automated drawing machines using an Etch A Sketch board, integrating both hardware and software aspects. The system's objective is to create an automation for art crafts powered by engineering and technology .  The system consists of a host computer for image processing , a microcontroller for motor control , and stepper motors for precise movement . The host computer processes input images, applies edge detection and path optimization algorithms , and generates G-code instructions . These instructions are then sent to an Arduino-based microcontroller , which controls the A4988 stepper motor drivers to manipulate the Etch A Sketch knobs. On the software side , we utilize OpenCV for image processing , employing Canny edge detection and a depth-first search (DFS) algorithm to generate continuous, single-line drawings. The G-code interpreter ensures smooth motor execution, translating digital path...

Week4: Intergration test and delivery

 Intergration Test Activities Week 4 is about intergarted test for whole system, including image reading, processing, data transmitting and motor controlling. Some probelms have been revealed and is solved later. - Full intergration of software components. It's been able to select any image and have it drawn on the etch a sketch. - Serveral teething issures found:     - Feedrate for stepper motors adjusted to be proportional to the coordinate     - Scaling issued with imaged used for sketch     - Double image formed due to a dead spot on the etch a sketch board, where the internal mechanism jumps and displaces the stepper motor. (We can do few about this problem) - Poster finished - Roles allocated for presentation at Bench Inspection Software - For the Aduino software: In order to make the motors move coordinatedly and asynchronously, we refactor the arduino driver software by introducing a non-blocking module in code. Details can be accessed at (http...
