1.安装VMware Workstation Pro 2.安装Ubuntu18.04 3.设置网络:NAT模式(联网) 4.安装Vmware tools(共享文件夹和随意缩小及可以复制粘贴) (https://blog.csdn.net/qweKelliy/article/details/88784494?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522163886486816780265470874%2522%252C%2522scm%2522%253A%252220140713.130102334..%2522%257D&request_id=163886486816780265470874&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~blog~baidu_landing_v2~default-1-88784494.pc_v2_rank_blog_default&utm_term=18.04%E5%AE%89%E8%A3%85vmware+tools%E6%AD%A5%E9%AA%A4&spm=1018.2226.3001.4450) 5.安装ROS 1.设置安装源 /etc/apt/sources.list.d/ros-latest.list' 2.设置密钥 sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116 在更新之前,需要安装公钥,否则无法验证签名,命令如下: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F42ED6FBAB17C654 3.更新软件列表 sudo apt update 4.安装ROS sudo apt-get install ros-melodic-desktop-full 5.安装完成之后初始化rosdep sudo apt install python-rosdep 6.初始化rosdep sudo rosdep init rosdep update 大多数情况下,做到这一步都会报错,可能会出现如下情况: ···Website may be down 或者 ···ERROR: unable to process source 错误原因是由于 raw.githubusercontent.com 被墙,程序无法下载相应的文件导致的,正常情况下我们也无法访问该网站。 问题解决: A. 下载rosdistro-master的压缩包,然后解压到主目录 cd ~ unzip rosdistro-master.zip mv rosdistro-master rosdistro 链接:https://pan.baidu.com/s/1z25LvAV1Z7dCTuzELqhOsA 提取码:75r1 B. 修改 20-default.list 文件 sudo gedit /etc/ros/rosdep/sources.list.d/20-default.list 内容修改如下: # os-specific listings first yaml file:///home/xxx/rosdistro/rosdep/osx-homebrew.yaml osx # generic yaml file:///home/xxx/rosdistro/rosdep/base.yaml yaml file:///home/xxx/rosdistro/rosdep/python.yaml yaml file:///home/xxx/rosdistro/rosdep/ruby.yaml gbpdistro file:///home/xxx/rosdistro/releases/fuerte.yaml fuerte # newer distributions (Groovy, Hydro, ...) must not be listed anymore, they are being fetched from the rosdistro index.yaml instead 注意:上述 xxx 需替换为自己的用户名 C. 修改 sources_list.py 文件 sudo gedit /usr/lib/python2.7/dist-packages/rosdep2/sources_list.py 注释原 DEFAULT_SOURCES_LIST_URL 一行,然后在其后添加如下一行,注意:xxx替换 DEFAULT_SOURCES_LIST_URL = 'file:///home/xxx/rosdistro/rosdep/sources.list.d/20-default.list' D. 修改 rep3.py 文件 sudo gedit /usr/lib/python2.7/dist-packages/rosdep2/rep3.py 注释原 REP3_TARGETS_URL 一行,然后在其后添加如下一行,注意:xxx替换 REP3_TARGETS_URL = 'file:///home/xxx/rosdistro/releases/targets.yaml' E. 修改 __init__.py 文件 sudo gedit /usr/lib/python2.7/dist-packages/rosdistro/__init__.py 注释原 DEFAULT_INDEX_URL 一行,然后在其后添加如下一行,注意:xxx替换 DEFAULT_INDEX_URL = 'file:///home/xxx/rosdistro/index-v4.yaml' 7.重新 rosdep update 备注: rosdep update 后, sudo rosdep init ,再 rosdep update ,最后修改B 8.添加 ROS 环境变量 ~/.bashrc source ~/.bashrc 9.安装 rosinstall sudo apt install python-rosinstall python-rosinstall-generator python-wstool build-essential 10.第一次启动ROS时,需要进行环境变量配置,执行如下命令 ~/.bashrc source ~/.bashrc 11.先开启三个终端,然后分别依次输入如下命令: roscore rosrun turtlesim turtlesim_node rosrun turtlesim turtle_teleop_key 然后将鼠标聚焦到输入最后一个命令的窗口,通过键盘的上下左右键,分别控制小王八的前进,后退,左转,右转。
