gazebo11 ros 集成环境安装

1、gazebo11安装

首先要搞清楚状态，环境要求很重要，gazebo11不是目前写gazebo最新版本，所以想安装gazebo11的，不要使用ubuntu22.04或更新的操作系统版本，我在这上面花了太多时间！gazebo版本与ubuntu操作系统版本有对应关系，对应关系不一致会导致安装出问题！

据我在官网了解gazebo11支持的系统为ubuntu18.04 \ ubuntu22.04  分别对应的ros 为 melodic   和 noetic!!!

常规操作，先更换ubuntu apt源

sudo vim /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

上面源加入sources.list文件中，可以将默认源#号注释掉

sudo apt-get update
sudo apt-get upgrade

更新源列表

检查gazebo版本

$ dpkg -l | grep gazebo
卸载老版本和相关插件

sudo apt-get remove gazebo9 gazebo9-common gazebo9-plugin-base libgazebo9:amd64 libgazebo9-dev:amd64 ros-melodic-gazebo-* 

设置镜像源和key

$ sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
$ wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
安装gazebo11

$ sudo apt-get update
$ sudo apt-get install gazebo11
$ sudo apt-get install libgazebo11-dev
输入gazebo命令，打开正常，安装gazebo成功。

2、ros安装

添加apt源文件

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

添加key

sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

更新源软件列表

sudo apt update

有需要可以安装ros 全功能版本

sudo apt install ros-
melodic
-desktop-full
也可以安装部分功能
sudo apt install ros-melodic-gazebo-ros-pkgs
sudo apt install ros-melodic-gazebo-ros-control
sudo apt install ros-
melodic
-ros-controllers
$ sudo apt install ros-
melodic
-ros-core$ 
sudo apt install ros-melodic-geometry2
配置ros的系统环境变量

source /opt/ros/melodic/setup.bash echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc source ~/.bashrc 测试环境 

启动roscore核心服务
roscore
rosrun gazebo_ros gazebo 可以通过ros运行gazebo就OK了！
