Build Instructions

1. Clone the repo onto the device of your choosing (in this case my NVIDIA Jetson Xavier)
2. Install dependencies:
   • ROS noetic or newer (Jetson Xavier install)
   • pynmea2 for parsing GPS data
   • Adafruit IMU libraries 1 and 2
   • librealsense 2.0 or newer—install with GPU/Cuda support for best performance, install pyrealsense as well if you want python support
   • IMU Tools
3. cd into the eracer folder, run bash init.bash to setup.
