My Autonomous RC car build: 'Donkey Car' WIP (20210325)

This is my progress log of creating a autonomous RC car.

What is a donkey car?

An opensource DIY self driving platform for small scale cars

Donkey® Car - Home

Recommended they have a discord

Discord  Server

Github autorope/donkeycar: Open source hardware and software platform to build a small scale self driving car.

How to build the hardware

Car body selection

Build a car. - Donkey Car

The only missing part I didnt already have was

3d print files

Donkey Chassis and Adapters - Current by aconway - Thingiverse

Donkey Self-Racing Car - Classic Version by aconway - Thingiverse

The newist version doesnt work for me....

Going to modify the files to split them into two pieces

Reference:  Why does the paper in Battlestar Galactica have the corners cut off? - Science Fiction & Fantasy Stack Exchange

I'm going to have to wait two weeks to print this because I had to buy more PLA filament. (sad face emoji)
