This tutorial describes the setup of a development workstation

Required Hardware

Step 1: Install Ubuntu

Current required version: Ubuntu 14.04

Follow the standard Ubuntu Installation Instructions for 14.04 (Desktop):

Step 2: Install ROS

Current supported version: ROS Indigo

Configure Ubuntu repositories

Configure your Ubuntu repositories to allow "restricted," "universe," and "multiverse." You can follow the Ubuntu guide for instructions on doing this.

Likely, they are already configured properly, and you only need to confirm the configuration.

Setup your sources.list

$ sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu trusty main" > /etc/apt/sources.list.d/ros-latest.list'

Setup your keys

$ wget http://packages.ros.org/ros.key -O - | sudo apt-key add -

Verify Latest Debians

$ sudo apt-get update

Install ROS Indigo Desktop Full

$ sudo apt-get install ros-indigo-desktop-full

NOTE: You may get a prompt about 'hddtemp' during the installation. You can safely answer 'No'.

Initialize rosdep

rosdep enables you to easily install system dependencies for source you want to compile and is required to run some core components in ROS.

$ sudo rosdep init
$ rosdep update

Install rosinstall

$ sudo apt-get install python-rosinstall

Step 3: Create Intera Development Workspace

Create ROS Workspace

$ mkdir -p ~/ros_ws/src
# ros_ws (short for ROS Workspace)

Source ROS and Build

ROS Indigo (Supported)

Source ROS Setup

$ source /opt/ros/indigo/setup.bash


$ cd ~/ros_ws
$ catkin_make

Step 4: Install Sawyer SDK Dependencies

ROS Indigo (Supported)

Install SDK Dependencies

$ sudo apt-get update
$ sudo apt-get install git-core python-argparse python-wstool python-vcstools python-rosdep ros-indigo-control-msgs ros-indigo-joystick-drivers ros-indigo-moveit-full

Step 5: Install Sawyer Research Robot SDK

Install Sawyer SDK

Checkout all required Github Repositories into your ROS workspace source directory: Use git clone or download the packages directly from Github:

$ cd ~/ros_ws/src
$ wstool init .
#### Once the repo is non-secret $ git clone https://github.com/RethinkRobotics/sawyer_robot.git
#### Until then, make sure you're SSH keys are added to github: https://help.github.com/articles/generating-an-ssh-key/
#### and then run the following:
$ git@github.com:RethinkRobotics/sawyer_robot.git
$ wstool merge sawyer_robot/sawyer_robot.rosinstall
$ wstool update

Source ROS Setup

You must use ROS Indigo to use RSDK, use command below:

# ROS Indigo
$ source /opt/ros/indigo/setup.bash


$ cd ~/ros_ws
$ catkin_make

Step 6: Configure Sawyer Communication/ROS Workspace

This step describes the configuration and setup of your ROS environment. This section assumes you have linked your workstation to the robot via Ethernet.
See Network Setup for recommended network configurations.

intera.sh ROS Environment Setup

The intera.sh script is a convenience script which allows for intuitive modification of the core ROS environment components. This user edited script will allow for the quickest and easiest ROS setup.

Further information and a detailed description is available on the SDK_Shell page.

Copy the intera.sh script

The intera.sh file already exists in intera_sdk repo, copy the file into your ros workspace.

$ cp ~/ros_ws/src/intera_sdk/intera.sh ~/ros_ws

Customize the intera.sh script

Please edit the intera.sh shell script making the necessary modifications to describe your development PC.

Using your favorite editor (gedit used for example)

$ cd ~/ros_ws
$ gedit intera.sh

Edit the 'robot_hostname' field

Sawyer's hostname is defaulted as the controller's serial number. The serial number can be located on the back of the robot's controller box.

Edit the 'your_ip' field

Modify where 'your_ip' is either your computer's hostname or the IP address of your PC.


Useful command for identifying your IP address:

$ ifconfig
# Result will be contained in the 'inet addr' field (Ubuntu) or 'inet' field (Gentoo Robot PC).

Alternatively, you may choose to use the hostname of your development PC rather than the PC's IP address. For instructions, press Expand on the right.

You may edit the 'your_hostname' field (only if not using 'your_ip'):


Important: This hostname must be resolvable to Sawyer. To test if your hostname is resolvable to Sawyer, please visit the development PC Hostname Validation page.

Important: Only set either ROS_IP *OR* ROS_HOSTNAME.

Setting of both ROS_IP and ROS_HOSTNAME will result in ROS_HOSTNAME taking priority, resulting in confusing environment setups. Comment out the unused method using the '#' as leading character.

Verify 'ros_version' field

Verify that the the 'ros_version' field matches the ROS version you are running:

This field will default to "indigo"


Save and Close intera.sh script

Please save and close the intera.sh script.

Initialize your SDK environment

From this point forward, your ROS environment setup should be as simple as sourcing the intera.sh script from the root of your Catkin workspace:

$ cd ~/ros_ws
$ ./intera.sh

Step 7: Verify Environment

A useful command for viewing and validating your ROS environment setup is:

$ env | grep ROS

The important fields at this point:

ROS_MASTER_URI - This should now contain your robot's hostname.

ROS_IP - This should contain your workstation's IP address.


ROS_HOSTNAME - If not using the workstation's IP address, the ROS_HOSTNAME field should contain your PC's hostname. Otherwise, this field should not be available.

Next Step

We will verify your network setup in the next section. Hello Robot!
