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

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


my printer model
doesnt fit on my printer need to fix use other file
even if i rotate it! darn...
at least 1 of them works

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

after some though i decided to modify the new one for uses on my mini using tinkercad
cut the object in two
I had to cut corners
Reference:  Why does the paper in Battlestar Galactica have the corners cut off? - Science Fiction & Fantasy Stack Exchange
trying out a quicker print

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