Donkey Car Datasets

Note: All tub data is in donkey 4.X format.

In this repository we store datasets for people to download and train their own pilots. In addition we also provide pre-trained models for some datasets (so far only the circuit launch set). This should allow you to run a donkey car pilot without the need to train one yourself.

The large dataset

This is the place for donkey datasets. The large dataset that was originally uploaded by Tawn is in the folder large_dataset. Here are some example images:

The circuit launch dataset

Recorded by Ed for the next races. We have trained a bunch of pilots on that data. Please get in touch if you have more tub data for this course, so we can create more robust pilots by combining those datasets in training.

Here are some example images:

GIT and large files

This git repo uses the git-lfs plugin to handle very large binary files.

It's easy to install the git-lfs plugin on your Windows, Mac or Linux laptop. See https://git-lfs.github.com/ . It's not quite that easy on a RaspberryPi; you'll have to build from source. See below.

Installation of git-lfs on RaspberryPi OS

See https://ar.al/2019/10/19/install-git-lfs-on-a-raspberry-pi/

Here is an updated version of that script the installs go 1.16.7.

• Create a project folder named git-lfs and cd into that folder
• Copy the code below into a script named build-git-lfs.sh in the git-lfs project folder you just made
• Make the script executable chmod +x build-git-lfs.sh
• Run the script. This script will download and install the go-language compiler, then checkout and build the git-lfs plugin from source.
• After the script has done, run the command git install lfs and you are good to go with this repo
