1. Have the Jetson Nano accept the packages.ros.org installation package
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release - sc) main" > / etc/apt/sources list. D/ros - latest. List'

  1. To update the apt
sudo apt update
Copy the code
  1. Install the ROS
sudo apt install ros-melodic-desktop
Copy the code

ROS Desktop Full is a more complete version, but is not recommended for embedded platforms because both 2D/3D emulators are installed at the same time, which takes up too much space for ROM, and may be too computationally intensive to use on Jetson Nano

  1. Rosdep initialization
sudo rosdep init
Copy the code
