Effective Robotics Programming with ROS - Third Edition

Overview of this book

Building and programming a robot can be cumbersome and time-consuming, but not when you have the right collection of tools, libraries, and more importantly expert collaboration. ROS enables collaborative software development and offers an unmatched simulated environment that simplifies the entire robot building process. This book is packed with hands-on examples that will help you program your robot and give you complete solutions using open source ROS libraries and tools. It also shows you how to use virtual machines and Docker containers to simplify the installation of Ubuntu and the ROS framework, so you can start working in an isolated and control environment without changing your regular computer setup. It starts with the installation and basic concepts, then continues with more complex modules available in ROS such as sensors and actuators integration (drivers), navigation and mapping (so you can create an autonomous mobile robot), manipulation, Computer Vision, perception in 3D with PCL, and more. By the end of the book, you’ll be able to leverage all the ROS Kinetic features to build a fully fledged robot for all your needs.

Understanding the ROS Community level

The ROS Community level concepts are the ROS resources that enable separate communities to exchange software and knowledge. These resources include the following:

  • Distributions: ROS distributions are collections of versioned metapackages that you can install. ROS distributions play a similar role to Linux distributions. They make it easier to install a collection of software, and they also maintain consistent versions across a set of software.

  • Repositories: ROS relies on a federated network of code repositories, where different institutions can develop and release their own robot software components.

  • The ROS Wiki: The ROS Wiki is the main forum for documenting information about ROS. Anyone can sign up for an account, contribute their own documentation, provide corrections or updates, write tutorials, and more.

  • Bug ticket system: If you find a problem or want to propose a new feature, ROS has this resource to do it.

  • Mailing lists: The ROS user-mailing...
