  • These steps no longer work. Ill update it later, or you can. Originally from the ROS wiki.

ROS is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management.

Setup

Get dependencies, and create alternate python dir to workaround shebang line in scripts that points to python3. Thanks to DavidS. Compiling gcc45 will take a long time.

pacman -S python2 cmake wget python-yaml python2-distribute python-yaml pil python-numpy
yaourt -S gcc45 log4cxx
mkdir /usr/local/bin/alt   
ln -s /usr/bin/python2 /usr/local/bin/alt/python

Rosinstall

The following lines will download the ROS source code using the rosinstall tool, and bootstrap the installation. The installation downloads all ROS stacks in subdirectories inside the ~/ros directory, one subdirectory for each stack in the rosinstall file.

First install rosinstall:

sudo easy_install-2.7 -U rosinstall

Then use rosinstall to download your preferred C-Turtle variant:

ROS-only: Includes basic ROS and tutorials.

rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=cturtle&variant=ros_only&overlay=no"

Base Install: ROS plus robot-generic stacks (e.g. navigation, visualization)

rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=cturtle&variant=base&overlay=no"

PR2 Install: ROS plus PR2-specific stacks, including PR2 simulator.

rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=cturtle&variant=pr2&overlay=no"

PR2 All Install: ROS plus PR2 and bleeding edge research/experimental stacks.

rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=cturtle&variant=pr2all&overlay=no"

NOTE: the instructions above download all stacks inside the ~/ros folder. If you prefer a different location, simply change the ~/ros in the commands above.

Environment Setup

You'll now need to update your environment. You can do this by typing:

source ~/ros/setup.bash

It's convenient if the ROS environment variables are automatically added to your bash session every time a new shell is launched, which you can do with the command below:

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

For Zsh users, change the last line of ~/ros/setup.zsh to

source $ROS_ROOT/tools/rosbash/roszsh

before running source ~/ros/setup.zsh Similarly, have the setup script called at the start of each new shell session with

echo "source ~/ros/setup.zsh" >> ~/.zshrc
. ~/.zshrc

Tutorials

Now, to test your installation, please proceed to the ROS Tutorials.
