iRobot Create ROS Hydro Drivers

I recently started messing around with ROS. I have a few common robotics development platforms laying around my lab, including an iRobot Create, which is essentially the Roomba without the vacuum parts. A lot of ROS projects are developed using the Create, so there's plenty of resources to pull from online.

Brown University has provided drivers for the Create, but the most recent ROS distro supported by the driver is Groovy. In my attempt to stay on the cutting edge, I had installed ROS Hydro, the newest distro at the time of writing this post. Fortunately, Hydro and Groovy aren't very different from each other. The biggest change since Groovy was the introduction of the catkin system which replaced rosbuild. 

From a previous Groovy installation that I was no longer using, I installed the brown drivers using:

sudo apt-get install ros-groovy-brown-drivers

After installing, I copied the "irobot_create_2_1" directory from inside "/opt/ros/groovy/stacks/brown_drivers" folder to my workspace's "src" directory. For example:

cp -r /opt/ros/groovy/stacks/brown_drivers ~/catkin_ws/src

Then, in my workspace directory, I ran catkin_make, and the driver ran perfectly! To run the driver use:

rosrun irobot_create_2_1 driver.py

 Thanks to Brown driver maintainers for updating the driver to be compatible with the new catkin system, everything works just fine so far. To test the driver, you can download BumpGo.py and place it in the "irobot_create_2_1/bin" directory. To test, simply enter:

rosrun irobot_create_2_1 bumpGo.py

The robot should then drive until the bump sensor is triggered, turn and continue. My future goals are to create a simple node to drive the robot using keyboard commands, interface an Xbox Kinect, and run some kind of SLAM algorithm. I really just wanted to make sure I added some documentation as to what I've done to run the create on ROS Hydro, regardless of how simple it was. (In the very likely event that I get distracted, come back months from now to continue the project, and forget everything I learned since then)

UPDATE:
Here's a link to the create drivers package:

UPDATE 2:
After reinstalling ROS on a new computer without my previous groovy installation, I had some trouble getting the above package to run. When I ran "rosrun irobot_create_2_1 driver.py", I would get a message which said " the rosdep view is empty: call 'sudo rosdep init' and 'rosdep update ". At first, the roomba would not connect and displayed some other error message I am now unable to reproduce. After replacing the battery the next morning, the create is now connecting without any problems! Let me know in the comments if you have any issues regarding this.
