ROS2安装

1. 设置编码

sudo locale-gen en_US en_US.UTF-8
sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
export LANG=en_US.UTF-8

2.设置软件源

sudo apt update && sudo apt install curl gnupg2 lsb-release
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
 
sudo sh -c 'echo "deb [arch=$(dpkg --print-architecture)] http://packages.ros.org/ros2/ubuntu $(lsb_release -cs) main" > /etc/apt/sources.list.d/ros2-latest.list'

3.安装ROS2

sudo apt update
sudo apt install ros-foxy-desktop

4.设置环境变量

source /opt/ros/foxy/setup.bash

  如果有安装ROS1,会提示一个警告

5.安装自动补全工具

sudo apt install python3-argcomplete

 跑几个例程测试一下:   先运行一个talker:

source /opt/ros/foxy/setup.bash
ros2 run demo_nodes_cpp talker

 再运行一个Listener

source /opt/ros/foxy/setup.bash
ros2 run demo_nodes_py listener

  ROS2的RWM默认使用的DDS是Fast RTPS,Cyclone DDS默认也安装好了,还可以这样安装RTI Connext:
sudo apt update
sudo apt install ros-foxy-rmw-connext-cpp # for RTI Connext (requires license agreement)
  安装之后通过环境变量即可切换DDS:
RMW_IMPLEMENTATION=rmw_connext_cpp

如果哪一天不喜欢了,还可以这样删除:
sudo apt remove ros-foxy-* && sudo apt autoremove
