Ubuntu 18.04 LTS +Melodic ROS配置TurtleBot3+运行gazebo仿真

1    确定ROS 发行版版本

在ROS wiki搜索(或者google)turtlebot install,会出现安装方法网址如下,

link:http://wiki.ros.org/turtlebot/Tutorials/indigo/Turtlebot%20Installation

如果你的ROS不是indigo版本的,点击图1中的turtlebot超链接:

                                                                                         图1

会进入这个页面,link:http://wiki.ros.org/action/show/Robots/TurtleBot?action=show&redirect=TurtleBot

下面有关于TURTLEBOT3和2的安装PKG,以安装turtlebot3的pkg为例,如图2所示,

                                                                                图2

依次安装这些pkg,以第一个turtlebot3这个PKG为例,点开超链接,如图3所示,

                                                                                        图3

点击右侧的dependencies,查看依赖包,点击依赖包安装全部之后才能继续安装turtlebot3这个包,这里有所不同的是,点开左下角的Source;git https://github.com/ROBOTIS-GIT/turtlebot3.git,在github上发现所有的依赖包都有,因此可以直接使用如下命令批量安装

cd ~/catkin_ws/src
git clone https://github.com/ROBOTIS-GIT/turtlebot3.git

下载好后,

方法一:可以选择在当前目录安装使用如下命令:

cd ~/catkin_ws
catkin_make
source ./devel/setup.bash

 

方法二,因为这是常用的包,可以将它放到ROS库的PKG中,通过如下方式查看pkg的位置

$ echo $ROS_PACKAGE_PATH
/home/simileciwh/catkin_ws/src:/opt/ros/melodic/share

用“:”相隔表示当前环境有两个ROS包的路径,/opt/ros/melodic/share是系统ROS的默认路径,通过如下指令安装

sudo su
#输入root密码
cd /home/<你的用户名对应的目录>/catkin_ws/src
cp -r <"刚刚下载的turtlebot3包的名字"> /opt/ros/melodic/share

注意使用这种直接拷贝的方式安装,一定要确保所有依赖关系都安装全了,不然当你运行到特定的节点时会报错,这时一句错我提示,讲该文件拷贝到catkin_ws/src文件夹下,然后使用方法一构建节点,根据提示将少的pkg安装上。

用如下指令查看PKG是否安装完成,如下所示就算安装结束了,可以直接使用roslaunch,或者rosrun运行节点。

$ rospack list
turtlebot3_automatic_parking /opt/ros/melodic/share/turtlebot3_applications-master/turtlebot3_automatic_parking
turtlebot3_automatic_parking_vision /opt/ros/melodic/share/turtlebot3_applications-master/turtlebot3_automatic_parking_vision

turtlebot3_autorace_detect /opt/ros/melodic/share/turtlebot3_autorace-master/turtlebot3_autorace_detect
turtlebot3_bringup /opt/ros/melodic/share/turtlebot3-master/turtlebot3_bringup

turtlebot3_follow_filter /opt/ros/melodic/share/turtlebot3_applications-master/turtlebot3_follow_filter
turtlebot3_follower /opt/ros/melodic/share/turtlebot3_applications-master/turtlebot3_follower
turtlebot3_gazebo /opt/ros/melodic/share/turtlebot3_simulations-master/turtlebot3_gazebo
turtlebot3_msgs /opt/ros/melodic/share/turtlebot3_msgs-master
turtlebot3_navigation /opt/ros/melodic/share/turtlebot3-master/turtlebot3_navigation
turtlebot3_panorama /opt/ros/melodic/share/turtlebot3_applications-master/turtlebot3_panorama
turtlebot3_slam /opt/ros/melodic/share/turtlebot3-master/turtlebot3_slam
turtlebot3_teleop /opt/ros/melodic/share/turtlebot3-master/turtlebot3_teleop

注意,有些PKG的安装方法在相应的github上有链接,按照作者的方式来,不要一味使用上诉方式

如果此时直接运行turtlebot3的相关节点会,提示“没有给turtlebot3选定model”,通过以下指令配置:

export TURTLEBOT3_MODEL=<在burger,waffle,waffle_pi三种中选择一个,一般我们选择burger>
#commond-line like this:
$ export TURTLEBOT3_MODEL=burger

2      gazebo仿真

    2.1 安装gazebo

link:http://gazebosim.org/tutorials/?tut=ros_wrapper_versions
如图4所示,

                                                                                     图4

点击图中installing gazebo_ros_pkgs,进入,link:http://gazebosim.org/tutorials?tut=ros_installing&cat=connect_ros

按照步骤进行安装。注意最好选择以源的形式进行安装。

测试基本完成后,用以下命令运行gazebo_ros仿真,即可完成。

$ roslaunch turtlebot3_gazebo turtlebot3_world.launch
#注意要先运行roscore

第一次运行gazebo仿真打开时间会较长,或者失败,请耐心多尝试几次即可。

3     可以在YouTube上学习一些关于此的方法

4     因为重装系统的原因又重新配置了turtlebot3的环境,遇到了一些新老问题,记录解决办法如下:
