Learning ROS for Robotics Programming

By: Aaron Martinez, Enrique Fernández

Overview of this book

<p>Both the amateur and the professional roboticist who has ever tried their hand at robotics programming will have faced with the cumbersome task of starting from scratch, usually reinventing the wheel. ROS comes with a great number of already working functionalities, and this book takes you from the first steps to the most elaborate designs possible within this software framework.</p> <p>"Learning ROS for Robotics Programming" is full of practical examples that will help you to understand the framework from the very beginning. Build your own robot applications in a simulated environment and share your knowledge with the large community supporting ROS.</p> <p>"Learning ROS for Robotics Programming" starts with the basic concepts and usage of ROS in a very straightforward and practical manner. It is a painless introduction to the fascinating world of robotics, covering sensor integration, modeling, simulation, computer vision, and navigation algorithms, among other topics.</p> <p>After the first two chapters, concepts like topics, messages, and nodes will become daily bread. Make your robot see with HD cameras, or navigate avoiding obstacles with range sensors. Furthermore, thanks to the contributions of the vast ROS community, your robot will be able to navigate autonomously, and even recognize and interact with you, in a matter of minutes.</p> <p>"Learning ROS for Robotics Programming" will give you all the background you need to know in order to start in the fascinating world of robotics and program your own robot. Simply, you put the limit!</p>

TurtleBot – the low-cost mobile robot


TurtleBot integrates in several simple and low-cost state-of-the-art hardware devices such as Microsoft's Kinect sensor, Yujin Robot's Kobuki, and iRobot's Create. It is a moving platform intended for indoor environments and with 3D perception capabilities by means of the Kinect. It is also easy to include more devices or even use with our own laptop to test our software, as it has several platforms at different heights, as the next picture shows:

Installing the TurtleBot simulation

The simulator of the TurtleBot does not come with the ROS repositories, so clone the turtlebot_simulator repository:

git clone https://github.com/turtlebot/turtlebot_simulator.git

Use the master branch or move to the correct one for your ROS distro. For example, for ROS Groovy do the following:

git checkout groovy

Now, build the sources:

rosmake

Running TurtleBot on simulation

To run TurtleBot in the empty world run the following code:

roslaunch turtlebot_gazebo turtlebot_empty_world...
