THE CHASSIS AND CAD

The NeoRacer is a 1:12 scale autonomous racing platform, and its full mechanical design is open. Every part lives in a public repository under CERN-OHL-S-2.0, a reciprocal open-hardware licence, so you can print the parts or open the CAD and modify them.

The NeoRacer rolling chassis with red oil-filled shocks and off-road wheels

The chassis

The chassis is the base of the car. It comes with the shocks, the motor, the ESC, and the steering servo already fitted. The battery and the electronics sit in the bay down the middle.

The NeoRacer front bumper with its four mounting screws

The front bumper

The front bumper bolts onto the nose with four screws. It protects the camera, the LiDAR, and the front suspension in a crash.

The rear wing with its mounting arms and screws

The rear wing

The rear wing bolts onto the tail with two arms. It protects the back of the car.

A NeoRacer-branded side cover panel

The side covers

The side covers close the electronics bay and keep dust off the wiring.

For any measurement not listed here, open neoracer-full-vehicle-drawing.dwg in the repository. It is the fully dimensioned 2D drawing of the car.

THE HARDWARE REPOSITORY

The mechanical design is tracked in neoracer-hardware-files, which holds three folders:

  • full-vehicle is the whole car: the editable FreeCAD project it is all designed in, plus exports for other CAD tools, a mesh for viewing and printing, and a 2D drawing.
  • 3d-printed-parts is the subset you print yourself.
  • oscore-board is the electronics: the schematic, the hardware manual, and the board model.

The repository README describes every file, which one to open for what you are doing, and how to clone it.
