Project Development

Week 1

This is my current sketch on my project idea

real

2

The points that I want this project to have include

  • The bot has to be able to move and sense objects
  • It should have a display that can make different expressions
  • It should have a camera inside it to be able to take pictures the area it is moving in
  • It should have a friendly and pet looking shape.

Week 2

This is the 3-d design of my project(you can see the layout changed quite a lot) I left the holes in the design to show a clearer view of how it’ll look.

The placement of the components are: - The head will hols a seperate circuit board with the 2 matrix displays and the esp32 camera. - The neck will be hollow to connect the display circuit board’s wires. - The ultrasonic sensor will pop out of the main body. - The battery will have a seperate case that I can access from the bottom to cahnge it, or charge it.

Week 4

This week I decied what microcontroller board to use with the advice from my seniors and instuctors.

Week 5

Cardboard prototype

We were assigned to make a prototype so we have a clearer vission of what we want to make, with where the components go and the size of the model.This was my prototype(without the wheels for now, because I think I will use plastic wheels from a toy, or a building kit)

These are the measurements for this model

This is the plan I have for where to place the components

components

After building this prototype, my whole idea of my project changed. I got a clearer idea of what I wanted to make and the measurements. I ended up changing the shape and placement of my components as well. After making this, I feel like my prokect is more relistic and possible. It feels like I made progress and actually managed to take a step forward (of course with a lot of help from the others.)

Week 6

I made a basic circuit sketch with one of my components, and now how to connect the other components as well.

circuit

My plan is to have 2 seperate circuit boards.

  • Firstly, of course the microcontroller, which will have all the pinouts needed for the other components as well.
  • Then, a board I plan to place in the head which will act as a seprate support for the esp32 cam and the matrix display. This is just to make it neater and more understandable.
