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 (https://github.com/SoySauceZhu/etchbot/tree/main/driver/main.cpp)
- Upgrade the gcode serial sender script. Which reads in a `SUCCESS` feedback once the motor has gone to the targeted position. Details can be accessed at (https://github.com/SoySauceZhu/etchbot/blob/main/serialSender.py).

The result of updates and debugging is a successful working demo on a Cartoon image.



Hardware

Hardware is fully assembled and tested in week3 and we haven't change it since then.

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...

Week1: Requirement Analysis, Timeline Assignment and Hardware Verification

Image
 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 rec...
