ROS 环境下 安装 turtlebot3 功能包及其仿真包 并测试 —— 全流程（报错及解决）

开启掘金成长之旅！这是我参与「掘金日新计划 · 12 月更文挑战」的第28天，点击查看活动详情

下载 turtlebot3 功能包

turtlebot 太老了可能，仿真只有indigo版本 ，直接用 3吧

ros的turtlebot wiki turtlebot官网教程

开始安装
turtlebot3 git网址

git上下载指定版本

git clone -b 版本名 总网址

git clone -b kinetic-devel https://github.com/ROBOTIS-GIT/turtlebot3.git

然后就等着下吧

下载完编译

报这个错误

感觉是少 turtlebot3_msgs 功能包

查看的确 turtlebot3_bringup 这个功能包 编译需要 turtlebot3_msgs

下载 turtlebot3_msgs 功能包

turtlebot3_msgs git网址

git clone -b kinetic-devel github.com/ROBOTIS-GIT…

再编译 就成功了 ！

因为要在仿真里做东西 所以继续下载 turtlebot3_simulations 里面有gazebo的内容

继续下载 turtlebot3_simulations

git clone -b kinetic-devel https://github.com/ROBOTIS-GIT/turtlebot3_simulations

再编译 也成功了

至此 turtlebot3 仿真 安装 成功了

试运行 一个 gazebo 仿真

 roslaunch turtlebot3_gazebo turtlebot3_world.launch

报错 不用担心 打开 turtlebot3_world.launch 这个文件 看到第一行 就是 TURTLEBOT3_MODEL 这个环境变量 没有被 指定 。 有这三个选择 burger, waffle, waffle_pi 一种解决办法就是 启动 roslaunch 前
在终端 定义 TURTLEBOT3_MODEL 变量 ，

export TURTLEBOT3_MODEL=burger

加入用 burger 的话

第二种方法： 但是这样不是在启动的时候很麻烦 ， 假如固定用一个的话，不如直接在launch文件里改 这样改就行 就是给 model 赋值 配置 robot_description 注释掉第一行 加入未注释内容

 <!-- <arg name="model" default="$(env TURTLEBOT3_MODEL)" doc="model type [burger, waffle, waffle_pi]"/> --> 
  <arg name="model" default="burger"/>

在运行

 roslaunch turtlebot3_gazebo turtlebot3_world.launch

成功启动
