CATPOO 2021 — Internal Structure

NOTE: This is a place for me to jot my thoughts regarding what my next robot will do. Expect many stealth edits.

See CATPOO 2021 — A New Beginning for an overview of the whole project.

Way back when, I designed that I wanted to learn how to create a circuit board from scratch. It was fun and I learned a lot. Unfortunately, one of the things that I learned was it takes forever to build proper circuits. It also costs a lot. For someone like myself who’s learning, it’s best to simply use some permaproto style Raspberry Pi HATs. Using 20mm standoffs and doubling up some stacking headers gives me plenty of space.

While this isn’t very space efficient, it still would fit inside of 4″ cube which is small enough for my purposes.

Layer Overview

  1. Raspberry Pi
    1. Nothing special here
    2. Leaning towards using the 20mm standoffs to allow more air flow over the CPU
  2. Motors 1 and 2
  3. Motors 3 and 4
  4. Sensors
    1. Not sure if I’m going to go with a simple ADC chip, or an Arduino for handling the range finders
    2. Might want to add GPS or environment sensors for shits and giggles down the road.
