About NVIDIA JetRacer

JetRacer is an open-source autonomous AI racecar built on the NVIDIA Jetson Nano and an off-the-shelf RC car chassis. It targets high-framerate vision-based road following using TensorRT-optimized neural networks, with interactive Jupyter notebooks for programming. NVIDIA provides per-chassis hardware setup guides and bills of materials for the Latrax Rally (1/18) and Tamiya TT-02 (1/10) builds. NVIDIA lists the Jetson Nano Developer Kit as end of life, and the repo was last updated in 2021.

How to build NVIDIA JetRacer

5 steps

Steps marked Motari summary condense the linked source; follow the source for exact instructions. Upstream step marks a step taken from the linked guide.

  1. Build the RC chassis

    For the Tamiya TT-02, print the drill jig, drill four 3 mm holes in the lower deck and countersink them, then assemble the kit. The Latrax Rally comes pre-assembled; the TT-02 build needs no soldering, the Latrax build does.

    Motari summarygithub.com/NVIDIA-AI-IOT/jetracer/blob/master/docs/tamiya/ha...

  2. Mount the Jetson Nano

    Print the base plate and camera mount from assets/. Fix M3 standoffs to the TT-02 lower deck, then mount the RC servo multiplexer, PCA9685 servo driver, Jetson Nano and camera mount to the base plate.

    Motari summarygithub.com/NVIDIA-AI-IOT/jetracer/blob/master/docs/tamiya/ha...

  3. Wire power and the PWM driver

    Wire the Jetson Nano I2C pins to the servo driver, connect driver channels 0 and 1 and the receiver channels to the multiplexer, and the steering servo and ESC to the multiplexer outputs. Power the Jetson from the USB battery through the barrel plug, per the hardware setup guide.

    Upstream stepgithub.com/NVIDIA-AI-IOT/jetracer/blob/b194ffd3477ce4e7b8bcf...

  4. Flash software and run notebooks

    Install the jetracer library and JetCam, then run the basic motion and road-following Jupyter notebooks.

    Motari summarygithub.com/NVIDIA-AI-IOT/jetracer/blob/master/docs/tamiya/ha...

  5. Train and optimize for speed

    Collect road-following data, train the model, and optimize with TensorRT for high-framerate driving.

NVIDIA JetRacer in simulation

Robot description files a simulator or CAD tool can load, linked at the commit they were found.

No URDF, MJCF, SDF, USD or Onshape model has been found in the sources.

The 3D specimen on this page is converted from assets/jetracer_cam_mount.stl at b194ffd, with the parts laid out side by side because the source has no assembly.

No reviewed builds of NVIDIA JetRacer yet.

A build log records the evidence (photos, a video, your repository), what the build cost, how long it took and what you changed. Each one is checked by Motari (until a maintainer claims this page) before it shows here, and reviewed builds count toward the reproducibility score.
