Install ROS

To start using ROS meta operating system for robots, we recommend to follow the next steps:

First you must install ROS. There already exist a very good tutorial to do so, and when you reach the part where you have to decide which version of ROS you want to install, we recommend to select the "Desktop-Full Install". An easy to follow tutorial on how to install ROS is in here(ROS Installation).
To get a quick and good tutorial for beginners see this page (BEGINNERS TUTORIAL). We recommend to read at least the beginners tutorials.
To start adding stacks please read next section.

3rd Party Stacks & Packages installations

Source code, stacks and packages are stored in different repositories depending on who is developing the code. Must common repositories are the SVN and Bazar, so, downloading and installation are covered in this tutorial, but first, you must know how to identify these data.

When You are interested in a particular software, as showed in the beginners tutorial, you should search for the topic, and eventually, you will find yourself in a web-page similar to the one that is shown in the Figure below.

In the Figure, it is important that you recognize five features:

Application Name (Green). This name, shows the main functionality of the stack. Sometimes has the same name as the STACK name, but is not always the case.
STACK name (Magenta). This is the actual name of the STACK. the others that are at the right side of the STACK name, are the sub-stacks or packages contained in this STACK. So, before considering to install the stack, first check if you have it already installed.
Dependencies (Yellow). Before starting to install this actual STACK, is very recommended that you first have this stack-dependencies installed. Yes, this means that you have to track back all the dependencies until you find one with all dependencies already installed. (Ros Base has install for you many of the most common, so don't worry so much).
Repository (Blue). Acording to the repository, you will proceed to to the installation. In next subsection we will show how to do Downloading an installation of ROS-PKG (SVN) and Bazar repositories.
SOURCE or trunk link (Red). This is the branch for downloading the SOURCE code.

From ROS-PKG: SVN Repository

ROS-PKG is a community repository for developing libraries that are generally robot agnostic. Many of the capabilities frequently associated with ROS, such as a navigation library and rviz visualizer, are developed in this repository. To see the list of stacks of this Repository, pleas go to this page: ROS-PKG STACKS LIST

In this part of the tutorial we will show how to install the Perception_PCL STACK, but steps are the same for any stack from the ROS-PKG Repository. To install any of the stacks here, do the following:

STACK=perception_pcl

First, make sure that you DON'T have this stack or package already installed. In terminal enter:

rosstack find $STACK

In this case, as the stack has been not installed, there will be a reply. In the case that you have it already installed, the result will be the Directory in which you have the stack installed. You can also search if the code is declared as a PACKAGE, so look for it entering in Terminal the following:

rospack find $STACK

In this case, it will complain again. So, what is next step?... ensure that we have already installed the Dependencies. IN THIS SPECIFIC case, Dependancies are:

common
common_msgs
driver_common
geometry
ros
ros_comm

We know in advance that these stacks, are part of the default ROS Base, so you don't have to track back any stack or package, so we can continue.

Make sure you have SVN installed.

sudo aptitude install subversion

Create the Directory where you want to install the stack, and go there..

mkdir -p $HOME/Ros_Stacks/
cd $HOME/Ros_Stacks/

Then you can checkout the SOURCE (trunk link) from the svn repository listed in the wiki. The trunk if you are curious is the default branch of code in a svn repository, as opposed to the experimental branch. So, when you go to the STACK web page, you will see the something like in the Figure above.

You should pay special attention to the Repository and to the Source lines. The Repository line, indicates the name of the STACK and the source indicates the link to experimental stack. What we want, is to get the whole Stack, so, in order to do that, first, copy the link of the SOURCE line but delete everything after the word " https:......../trunk/ ". then in terminal, save it in a variable, for example:

SOURCE="https://code.ros.org/svn/ros-pkg/stacks/perception_pcl/trunk"

Now that we have the STACK name and the SOURCE, we just do the following in Terminal

svn co $SOURCE $STACK

After downloaded, edit your ROS_PACKAGE_PATH in your .bashrc

export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH
echo "export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH" >> $HOME/.bashrc

Almost finish. To actually install the stack, you have to enter to the stack directory and install the STACK. to do so, just enter in terminal:

roscd $STACK
rosmake --rosdep-install

Ok, now you can try your STACK.

From Bazar (bzr) Repository

First, make sure that you have the bazar installed in your pc

sudo apt-get install bzr

Then prepare the directory where you want to install the STACK.

mkdir -p $HOME/Ros_Stacks/
cd $HOME/Ros_Stacks/

Get the SOURCE code, that is the link of the web-page, example

SOURCE="lp:sr-ros-interface"
STACK="shadow_robot"

bzr branch $SOURCE
mv sr-ros-interface/shadow_robot .
rm -r sr-ros-interface

Export the PATH to $ROS_PACKAGE_PATH

export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH
echo "export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH" >> $HOME/.bashrc

finally, build the STACK

roscd $STACK
rosmake --rosdep-install

From Mercurial (hg) Repository

First, make sure that you have the Mercurial installed in your pc

sudo apt-get install mercurial

Then prepare the directory where you want to install the STACK.

mkdir -p $HOME/Ros_Stacks/
cd $HOME/Ros_Stacks/

Get the SOURCE code, that is the link of the web-page. As a example , we install the control STACK

STACK="control"
SOURCE="https://bitbucket.org/sglaser/control"

cd $HOME/Ros_STACKS
hg clone $SOURCE

Export the path

export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH
echo "export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH" >> $HOME/.bashrc

Finally, build the Stack

roscd $STACK
rosmake --rosdep-install

Kinect Stack

ROS Kinect is an open source project focused on the integration of the Microsoft Kinect sensor with ROS. The kinect ROS stack contains low-level drivers, visualization launch files, and PCL/OpenCV tutorials/demos.

Install Drivers

In the C-Turtle distribution, the use of Kinect was done trough the Kinect Stack, now, in Diamondback, it is done by the ni STACK. let us see how to install it.

First, we need to have installed the following STACKS. To know how to install them, please read 3rd Party stacks installation.

openni_kinect

Shadow Robot Stack

Installation

In this section we present some useful steps to install the shadow_robot STACK, although this stack is still under development, installation steps should be similar in future releases.

To Install the full shadow_robot STACK, You first need installed the following stacks:

bosch_drivers
pr2_common
pr2_mechanism
trajectory_msgs PACKAGE (use roscd trajectory_msgs to check if is already installed)
control (it's in Mercurial Repository)
pr2_controllers
pr2_simulator

Because the developer of this STACK Ugo Cupcic recommend it, instead of just installing the whole STACK at once (that will give several errors), we first download the full STACK and then begin installing the sr_hand PACKAGE, then the sr_control_gui PACKAGE, and finally we will add the rest of the packages.

As you will see in the, the shadow_robot STACK and sr_hand PACKAGE, the repository is in Bazar, so, first make sre that you have the bazar installed.

sudo apt-get install bzr

Then prepare the directory where you want to install the STACK.

mkdir -p $HOME/Ros_Stacks/
cd $HOME/Ros_Stacks/

Get the SOURCE code..:

SOURCE="lp:sr-ros-interface"
STACK="shadow_robot"

bzr branch $SOURCE
mv sr-ros-interface/shadow_robot .
rm -r sr-ros-interface

If that fails, this is an alternative way to download the SOURCE code .

wget http://launchpad.net/sr-ros-interface/release1.2/1.2.0/+download/release1.2.tar.gz
tar xvvzf release1.2.tar.gz
mv release1.2/shadow_robot .
rm -r release1.2

Now, export the path to the ROS_PACKAGE_PATH

export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH
echo "export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/$STACK:$ROS_PACKAGE_PATH" >> $HOME/.bashrc

Until now, we just downloaded the whole STACK, and as Ugo Cupcic recommended, we will install first the sr_hand PACKAGE, so, to do that, in Terminal enter:

PACKAGE="sr_hand"
roscd $PACKAGE
rosmake --rosdep-install

Now, let us procede with the sr_control_gui PACKAGE

PACKAGE="sr_control_gui"
roscd $PACKAGE
rosmake --rosdep-install

Now, build the cyberglove PACKAGE

PACKAGE="cyberglove"
roscd $PACKAGE
rosmake --rosdep-install

Now. build the dataglove STACK. To do so, enter the following in Terminal:

STACK="dataglove"
export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/shadow_robot/$STACK:$ROS_PACKAGE_PATH
echo "export ROS_PACKAGE_PATH=$HOME/Ros_Stacks/shadow_robot/$STACK:$ROS_PACKAGE_PATH" >> $HOME/.bashrc
roscd $STACK
rosmake --rosdep-install

Now install the dataglove_processing PACKAGE

PACKAGE="dataglove_processing"
roscd $PACKAGE
rosmake --rosdep-install

Now build the sr_remappers

PACKAGE="sr_remappers"
roscd $PACKAGE
rosmake --rosdep-install

This Launchs the Node

roslaunch sr_hand srh_motor.launch

Now Display the Hand with the RVIZ

roslaunch sr_hand rviz_motor.launch

The RVIZ will not display automatically the Hand, because you have to add it to the display interface, To do this, click on Add at the bottom left of rviz, then select Robot Model. You can also visualize the targets of the hand by using a second robot_model in rviz. Don't forget to specify the correct topics:

To display the hand position: set Robot Description to hand_description and TF Prefix to /srh/position (on the left hand side, in the parameters of your robot_model).
To display the hand targets: set Robot Description to hand_description and TF Prefix to /srh/target.

Now, start the GUI Interface

rosrun sr_control_gui sr_control_gui

UPDATE

roslaunch sr_hand sr_arm_motor.launch

roslaunch sr_hand rviz_motor.launch

rosrun sr_control_gui sr_control_gui

roslaunch cyberglove cyberglove.launch

Streaming images from USB cameras

I used the ros-electric-brown-perception DEB package, in combination with ROS Electric Emys, Ubuntu 11.04 and a Logitech webcam. Once this package is installed, to start the streaming you need to (1) have the roscore running, (2) set one environment variable and (3) run gscam.

 roscore

 roscd gscam
 cd bin
 export GSCAM_CONFIG="v4l2src device=/dev/video0  ! video/x-raw-rgb ! ffmpegcolorspace"

 rosrun gscam gscam

You can display the image stream with image_view:

 rosrun image_view image_view image:=/usb_cam/image_raw

As and alternative to setting the environment variable, you can create a launch file for gscam:

 cd ros/electric/stacks/brown_perception/gscam
 mkdir launch
 nano launch/gscam.launch

The content of the launch file should be:

 <launch>
   <env name="GSCAM_CONFIG" value="v4l2src device=/dev/video0 ! video/x-raw-rgb ! ffmpegcolorspace"/>
   <node pkg="gscam" name="gscam" type="gscam"  output="screen"/>
 </launch>

You can then run this command to start the streaming (this also starts the roscore, should that be needed):

 roslaunch gscam gscam.launch
