ROS2入门教程-windows安装ROS2

说明：

  • 介绍怎么在视窗系统下安装ROS2

系统要求

  • 建议使用win 10系统

安装ROS2的前提准备

  • 1.安装的巧克力

  • Chocolatey的相关下载链接：https：//chocolatey.org/

  • 2.通过Chocolatey安装Python

  • 打开命令提示符，然后键入下面的命令：

choco install -y python

  • 3.安装OpenSSL

  • 从下面提供的链接下载OpenSSL安装程序。请下载Win64 OpenSSL v1.0.2，不要下载Win32或者Light版本。

  • OpenSSL的相关链接：https：//slproweb.com/products/Win32OpenSSL.html

  • 使用默认参数运行安装程序。然后，定义环境变量（下面的命令假定使用了默认安装目录）：

setx -m OPENSSL_CONF C:OpenSSL-Win64inopenssl.cfg

#Add C:OpenSSL-Win64in to your PATH

  • 7.安装依赖项

  • 请从这个GitHub存储库下载这些软件包。

    • asio.1.10.6.nupkg

    • 本征3.3.3.nupkg

    • TinyXML的-usestl.2.6.2.nupkg

    • tinyxml2.4.1.0.nupkg

  • 下载完成后，执行以下命令：

choco install -y -s <PATHTODOWNLOADS> asio eigen tinyxml-usestl tinyxml2

# <PATHTODOWNLOADS>为已下载软件包的文件夹的对应路径
  • 您还必须安装pip一个python包，yaml：
python -m pip install -U pyyaml setuptools

下载ROS2

  • ROS2的相关下载链接：https：//github.com/ros2/ros2/releases

  • 下载适用于Windows的最新软件包，例如ros2-package-windows-AMD64.zip。

    • 注意：可能有多个二进制下载选项可能导致文件名不同。

  • 解压缩zip文件（我们假设C:dev os2）。

设置ROS2的环境

  • 执行以下命令以及source RO2的配置文件来设置工作空间
call C:dev
os2local_setup.bat
  • 如果您下载了具有OpenSplice支持的版本并希望将其用作中间件，则必须另外获取OpenSplice安装文件。只有这样after你才能获得ROS 2：
call "C:opensplice67HDEx86_64.win64
elease.bat"

试试一些例子

  • 打开一个终端，执行以下命令：
ros2 run demo_nodes_cpp talker
  • 打开一个新终端，执行以下命令：
ros2 run demo_nodes_py listener
  • 运行结果图如下：

请输入图片描述

排除故障

  • 如果不能运行例子且出现缺少dll的报错，请检查前面安装的外部依赖的所有的库，例如：OpenCV的PATH环境变量是否设置正确

  • 如果前面在设置时忘记执行call C:dev os2local_setup.bat命令，则可能无法运行演示

Installing ROS 2 on Windows

This page explains how to install ROS 2 on Windows from a pre-built binary package.

System requirements

As of beta-2 only Windows 10 is supported.

Installing prerequisites

Install Chocolatey

Chocolatey is a package manager for Windows, install it by following their installation instructions:

https://chocolatey.org/

You’ll use Chocolatey to install some other developer tools.

Install Python

Open a Command Prompt and type the following to install Python via Chocolatey:

> choco install -y python

Install OpenSSL

Download an OpenSSL installer from this page. Scroll to the bottom of the page and download Win64 OpenSSL v1.0.2. Don’t download the Win32 or Light versions.

Run the installer with default parameters. The following commands assume you used the default installation directory:

  • setx -m OPENSSL_CONF C:OpenSSL-Win64inopenssl.cfg

You will need to append the OpenSSL-Win64 bin folder to your PATH. You can do this by clicking the Windows icon, typing “Environment Variables”, then clicking on “Edit the system environment variables”. In the resulting dialog, click “Environment Variables”, then click “Path” on the bottom pane, finally click “Edit” and add the path below.

  • C:OpenSSL-Win64in

Install Visual Studio

Install Visual Studio 2019.

If you already have a paid version of Visual Studio 2019 (Professional, Enterprise), skip this step.

Microsoft provides a free of charge version of Visual Studio 2019, named Community, which can be used to build applications that use ROS 2:

Make sure that the Visual C++ features are installed.

An easy way to make sure they’re installed is to select the Desktop development with C++ workflow during the install.

Make sure that no C++ CMake tools are installed by unselecting them in the list of components to be installed.

Install additional DDS implementations (optional)

ROS 2 builds on top of DDS. It is compatible with multiple DDS or RTPS (the DDS wire protocol) vendors.

The package you downloaded has been built with optional support for multiple vendors: eProsima FastRTPS, Adlink OpenSplice, and RTI Connext as the middleware options. Run-time support for eProsima’s Fast RTPS is included bundled by default. If you would like to use one of the other vendors you will need to install their software separately.

RTI Connext

To use RTI Connext DDS there are options available for university, purchase or evaluation

After installing, run RTI launcher and point it to your license file.

Set the NDDSHOME environment variable:

set "NDDSHOME=C:Program Files
ti_connext_dds-5.3.1"

If you want to install the Connext DDS-Security plugins please refer to this page.

Install OpenCV

Some of the examples require OpenCV to be installed.

You can download a precompiled version of OpenCV 3.4.6 from https://github.com/ros2/ros2/releases/download/opencv-archives/opencv-3.4.6-vc16.VS2019.zip .

Assuming you unpacked it to C:opencv, type the following on a Command Prompt (requires Admin privileges):

setx -m OpenCV_DIR C:opencv

Since you are using a precompiled ROS version, we have to tell it where to find the OpenCV libraries. You have to extend the PATH variable to C:opencvx64vc16in.

Install dependencies

There are a few dependencies not available in the Chocolatey package database. In order to ease the manual installation process, we provide the necessary Chocolatey packages.

As some chocolatey packages rely on it, we start by installing CMake

> choco install -y cmake

You will need to append the CMake bin folder C:Program FilesCMakein to your PATH.

Please download these packages from this GitHub repository.

  • asio.1.12.1.nupkg

  • eigen-3.3.4.nupkg

  • tinyxml-usestl.2.6.2.nupkg

  • tinyxml2.6.0.0.nupkg

  • log4cxx.0.10.0.nupkg

Once these packages are downloaded, open an administrative shell and execute the following command:

> choco install -y -s <PATHTODOWNLOADS> asio eigen tinyxml-usestl tinyxml2 log4cxx

Please replace <PATHTODOWNLOADS> with the folder you downloaded the packages to.

You must also install some python dependencies for command-line tools:

python -m pip install -U catkin_pkg empy lark-parser lxml numpy opencv-python pyparsing pyyaml setuptools

RQt dependencies

python -m pip install -U pydot PyQt5

Downloading ROS 2

Note

There may be more than one binary download option which might cause the file name to differ.

Note

To download the ROS 2 debug libraries you’ll need to download ros2-dashing-*-windows-debug-AMD64.zip

  • Unpack the zip file somewhere (we’ll assume C:dev os2).

Set up the ROS 2 environment

Start a command shell and source the ROS 2 setup file to set up the workspace:

> call C:dev
os2local_setup.bat

It is normal that the previous command, if nothing else went wrong, outputs “The system cannot find the path specified.” exactly once.

Try some examples

In a command shell, set up the ROS 2 environment as described above and then run a talker:

> ros2 run demo_nodes_cpp talker

Start another command shell and run a listener:

> ros2 run demo_nodes_py listener

You should see the talker saying that it’s Publishing messages and the listener saying I heardthose messages. Hooray!

If you have installed support for an optional vendor, see this page for details on how to use that vendor.

Troubleshooting

  • If at one point your example would not start because of missing dll’s, please verify that all libraries from external dependencies such as OpenCV are located inside your PATH variable.

  • If you forget to call the local_setup.bat file from your terminal, the demo programs will most likely crash immediately.

  • If you see an error related with FastRTPS failing to be loaded, see troubleshooting section in development install instructions.

Build your own packages

If you would like to build your own packages, refer to the tutorial "Using Colcon to build packages".
