蓝桥ROS机器人之ROS1和ROS2切换

首先，确保完成配置：

​​☞  蓝桥ROS机器人系统更新和功能包安装记录​​

---

为了确保安装速度，请使用国内源：

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'

如果功能包不全：

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

ROS1：

source /opt/ros/kinetic/setup.bash

source /opt/ros/kinetic/setup.zsh

ROS2：

source /opt/ros/ardent/setup.bash

source /opt/ros/ardent/setup.zsh

如果弄成开启终端可切换的模式使用：

echo "ros1 kinetic(1) or ros2 ardent(2)?"
read edition
if [ "$edition" -eq "1" ];then
  source /opt/ros/kinetic/setup.bash
else
  source /opt/ros/ardent/setup.bash
fi

zsh

echo "ros1 kinetic(1) or ros2 ardent(2)?"
read edition
if [ "$edition" -eq "1" ];then
  source /opt/ros/kinetic/setup.zsh
else
  source /opt/ros/ardent/setup.zsh
fi
