A high-end RC drift car is modified with 3D printed PELA blocks, LEGO technics, a Raspberry Pi 3+ and camera to drive itself. Snap on additional sensors and custom body parts as your design evolves. At Futurice, we use this to compete and learn. Our different offices race each other to see who has the mad deep learning skills to drive the car around a track the fastest.
This drift car is a work in progress. PELA Blocks and some imagination with LEGO technics will offer you all the parts you need and see here in the picture. Instructions are currently a bit thin as we iterate fast. We’ll get to it. Promise.
Please see donkeycar.com for help with the basic software setup. This car is a high performace, pimped-out version of what you find there.
These open source designs are brought to you by Futurice and contributions from the community. Come work with the best.
The software needed is free and open source, OpenSCAD. You can probably learn it in less than an hour.

If you prefer to avoid git, you can download the files instead.
git clone --recurse-submodules firstname.lastname@example.org:LEGO-compatible-gadgets/PELA-drift-car.git
cd PELA-drift-car\PELA-parameteric-blocksand then
git lfs install
git submodule update --remoteor cd into the submodule and
git reset --hard origin/master
See Advanced Setup for git sparce checkout.
IMPORTANT: The STL models must be customized for your material, printer and slicer. First calibrate the PELA blocks for your printer to achieve a nice snap fit.
See also Advanced Calibration
If you later update the PELA-blocks project to a newer version, you risk overwirting and loosing your calibration customizations. The simplest solution is to create a backup copy those settings.
cp PELA-parameters.scad ../PELA-parameters-backup.scad
cp PELA-print-parameters.scad ../PELA-print-parameters-backup.scad
Edit the OpenSCAD files to generate different views such as one finger at a time.
Be patient, have a nice meal and a coffee, the models are complex and render slowly.

These designs are by PELA project contributors, not by the LEGO corporation. They are compatible with LEGO and similar blocks available from multiple manufacturers and online projects. The associated patents have expired. These designs are not identical to LEGO; they have been specially modified for easy 3D printing and offered in the spirit of open source collaborative innovation.
If what you want is available as injection molded plastic, buy it for the higher quality and durability. These model are helpful when you want something customized, a special color, an unusual material, and for replacement parts when you just can’t wait.
