3、安装ROS

3.1 Configure your Ubuntu repositories

3.2 Setup your sources.list

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

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

3.4 Installation

sudo apt-get update

sudo apt-get install ros-kinetic-desktop-full

3.5 Environment setup

echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc

source ~/.bashrc

3.6 Dependencies for building packages

1 在桌面打开终端输入下面指令

sudo chmod 777 /etc

此指令为获取etc中的权限,操作成功后如下:每个图标右下角有一把锁

2 在etc中手动创建(一定要手动创建,别自作聪明指令创建,以防小白入坑)

目录入————》》》/etc/ros/rosdep/sources.list.d

多说一句,etc目录的进入方法

3 打开网址:https://site.ip138.com

输入raw.githubusercontent.com


随便挑选一个ip地址,我选的是美国的。

新建一个空白文档如下编辑:


4 在桌面打开终端输入如下指令:

sudo vi /etc/hosts

将刚刚创建的文档里的信息粘贴如下:

vi编辑器,将鼠标光标移动到需要编辑的地方,按字母i进入编辑模式,粘贴好后ctrl+c退出编辑状态,在输入冒号加wq在按回车(:wq)

4 创建项目

mkdir -p ~/catkin_ws/src

cd~/catkin_ws/src

catkin_init_workspace

cd..

catkin_make

source~/catkin_ws/devel/setup.bash

添加三句gedit ~/.bashrc

source /usr/share/gazebo-7/setup.sh

source /opt/ros/kinetic/setup.bash

source $HOME/catkin_ws/devel/setup.bash

下载UUV模型

sudo apt install ros-kinetic-uuv-simulator

下一步cd~/catkin_ws/src

克隆git clone https://github.com/uuvsimulator/lauv_gazebo.git

下载的uuv_simulator放到 src里

运行环境 roslaunch uuv_gazebo_worlds ocean_waves.launch

roslaunch lauv_description upload.launch mode:=default x:=0 y:=0 z:=0 namespace:=auv
