Week 15: System Integration

Assignment

Design and document the system integration for your final project.

I started off this week by making this schedule for my final project tasks in google sheets so that I could be able to manage my time better:

3D deisgning final project:

I used Fusion 360 to 3D design the desk bot, which is supposed to look like a penguin. I also considered using Blender, but since I’m more familiar with Fusion, I decided to stick with it. I first created the overall silhouette using a quadball in Fusion Forms, then kept adjusting and shaping it until I got the look I wanted.

Then after getting the overall shape of the penguin in Forms, I switched back to Solid began working on the details such as the holders and cutouts for electronics.

All front shells/plates are for mounting the exterior components. There are two front plates, one for the head and the other for the belly. Both are meant to mount a 1.3 in oled screen but a rotary encoder will also be mounted on the belly plate in addition.I created the frame cutouts on the plates and then the stadoff which are like poles that go through the holes on the module and then a similar cap will be used to sort of lock the module.

This is the belly plate:

And this is the face plate:

Mounting external components:

Mounting Internal components:

All internal components like the pcb board, rtc, speaker etc will be mounted on the back shells using stadoffs as well.Right now, I am working on the internal mounting part.

Working on the pcb board:

This week I was also able to mill out my board and solder all the components 😮‍💨

I modified the previous versions of board in Kicad.Initially it had short circuits and ground power issues but then I modified that and hopefully it works🤞.This is the schematics and the pcb.
