ros install golang

ROS (Robot Operating System) is a widely used robot development platform. It is written in C, but also supports other programming languages such as Python and Java. If you want to use Go language to write nodes in ROS, then you need to follow the steps below to install Go.

1. Download Go

First, you need to download the Go binary. You can find the latest version of Go on the official website (https://golang.org/dl/). Download the tarball appropriate for your operating system and extract it to a directory of your choice. We will assume that you extracted it to the /usr/local/go/ directory.

2. Configure environment variables

In order to access Go in the terminal, you need to add the path to the Go binary to your PATH environment variable. Open your terminal and enter the following command at the command line:

export PATH=$PATH:/usr/local/go/bin

If you want to permanently modify the PATH environment variable, you can add this command to your .bashrc file.

3. Testing the installation

Now you can test your Go installation by entering the following command:

go version

If Go installed successfully, you should see to output similar to the following:

go version go1.16.5 linux/amd64

4. Install Go ROS package

There is a ROS package (go-ros) that already provides support for Go. To use Go with ROS, you need to install this package. In your ROS workspace, enter the following command:

mkdir -p src/github.com/akio/rosgo cd src/github.com/akio/rosgo git clone https://github.com/akio/rosgo.git ./ cd rosdep install rosgo

5. Testing the Go ROS package

You can test whether the Go ROS package is successful by running the test node of rosgo Install. Enter your ROS workspace and run the following command:

roscore & cd src/github.com/akio/rosgo go run tools/testsub.go /test & go run tools/testpub.go /test &

Now, you should see two terminal windows printing different messages. This means you successfully wrote Node using Go in ROS.

Summary

Using Go in ROS allows you to write faster and more efficient code. However, you may encounter some problems during the installation of Go and Go ROS packages. If you follow the steps above and spend some time debugging, you will be able to install and use Go with ease.
