###注：由于使用国外的源安装ROS特别缓慢，因此要尽量使用国内的源
#添加镜像源
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'
#添加公钥
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
#更新软件包索引
sudo apt update
#安装桌面完整版
sudo apt install ros-melodic-desktop-full
#查找可用软件包

#初始化rosdep
sudo rosdep init
rosdep update
#设置环境变量
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
source ~/.bashrc
