ROS Programming: Building Powerful Robots

By: Anil Mahtani, Aaron Martinez, Enrique Fernandez Perdomo, Luis Sánchez, Lentin Joseph

Overview of this book

This learning path is designed to help you program and build your robots using open source ROS libraries and tools. We start with the installation and basic concepts, then continue with the more complex modules available in ROS, such as sensor and actuator integration (drivers), navigation and mapping (so you can create an autonomous mobile robot), manipulation, computer vision, perception in 3D with PCL, and more. We then discuss advanced concepts in robotics and how to program using ROS. You'll get a deep overview of the ROS framework, which will give you a clear idea of how ROS really works. During the course of the book, you will learn how to build models of complex robots, and simulate and interface the robot using the ROS MoveIt motion planning library and ROS navigation stacks. We'll go through great projects such as building a self-driving car, an autonomous mobile robot, and image recognition using deep learning and ROS. You can find beginner, intermediate, and expert ROS robotics applications inside! It includes content from the following Packt products: ? Effective Robotics Programming with ROS - Third Edition ? Mastering ROS for Robotics Programming ? ROS Robotics Projects

Summary


This chapter provided you with general information about the ROS architecture and how it works. You saw certain concepts, tools, and samples of how to interact with nodes, topics, and services. In the beginning, all of these concepts might look complicated and without use, but in upcoming chapters, you will start to understand their applications.

It is useful to practise using these terms and tutorials before continuing because in upcoming chapters we will assume that you know all of the concepts and uses.

Remember that if you have queries about something and you cannot find the solution in this section, you can use the official resources of ROS from http://www.ros.org. Additionally, you can ask the ROS Community questions at http://answers.ros.org.

In the next chapter, you will learn how to debug and visualize data using ROS tools. This will help you to find problems, know whether what ROS is doing is correct, and better define what your expectations from it are.
