Week 20 : Project Developement



Objectives

what is the deadline? How much time do I have left?
What tasks have been completed, and what tasks remain
How will I complete the remaining tasks on time?
What has worked?
What hasn't?
What questions still need to be resolved?
What have you learned?


I divided the steps for the project as below.

1. Making a Board for the Final Project.
2: Embedded programming
3. Creating the App, Testing the board with serial communication and then the bluetooth serial interface.
4. Mechanical Designing.
5. 3D Printing.
6. Laser Cutting and Assembling.
7.Assembly.
8.Testing

  • What is the deadline? How much time do I have left?

    • My project presentation is scheduled for 19 June, got few days for me to complete the task.

  • what tasks have been completed, and what tasks remain?

    • I have completed designing some wheels and base for the Car, and designed the motor holders.

    I have build an Android Application for controlling through Bluetooth interface.

    I have milled a board for the project.

    I have 3d printed wheels .


  • Tasks remaining


    • Now I have to Make a physical chassis and other parts necessary and try the programming part.

    I have to test the app

    .

  • How will I complete the remaining tasks in time?

    • Already its very late, i should plan it good to finish things.

  • what has worked?

    • The Android application is working fine and I have tested the motors.

  • What hasn't?

    • After trying the programming part with the Attiny 44 Board, Attiny 44 doesnt really support serial communication with multiple conditions.
    As I have to rotate two motors in total four directions, the Attiny 44 is not working and I am trying my best to work it.
    If it doesn't work , I would choose the Atmega 328p board I built for the Input Week.

    The Bluetooth Sensors in India are always faulty

  • What questions still need to be resolved?


    • Baud Rate issues in Serial Communication
    RX TX serial communication issues

  • What have you learned?

    • I have learned a lot of things.
    Familiourised different design tools like Soliworks, Fusion 360, Eagle.
    Taught myself PCB milling , soldering and learned to operate the Digital Oscilloscope, Digital Voltage Regulator etc.
    Learned to operate 3d printers, Shopbot, Lasercutting machine, milling machine with ease.
    Learned embedded programming and learned the structure and data sheets of ATtiny 44 and Atmega328p and Arduino Uno.
    Learned MIT app inventor.
