Overview of this book

ROS is a robust robotics framework that works regardless of hardware architecture or hardware origin. It standardizes most layers of robotics functionality from device drivers to process control and message passing to software package management. But apart from just plain functionality, ROS is a great platform to learn about robotics itself and to simulate, as well as actually build, your first robots. This does not mean that ROS is a platform for students and other beginners; on the contrary, ROS is used all over the robotics industry to implement flying, walking and diving robots, yet implementation is always straightforward, and never dependent on the hardware itself. ROS Robotics has been the standard introduction to ROS for potential professionals and hobbyists alike since the original edition came out; the second edition adds a gradual introduction to all the goodness available with the Kinetic Kame release. By providing you with step-by-step examples including manipulator arms and flying robots, the authors introduce you to the new features. The book is intensely practical, with space given to theory only when absolutely necessary. By the end of this book, you will have hands-on experience on controlling robots with the best possible framework.

Chapter 4. Navigating the World with TurtleBot

In the previous chapter, the TurtleBot 2 robot was described as a two-wheeled differential drive robot developed by Willow Garage. The setup of the TurtleBot 2 hardware, netbook, network system, and remote computer were explained, so the user could set up and operate their own TurtleBot. Then, the TurtleBot 2 was driven around using keyboard control, command-line control, and a Python script. TurtleBot 3 was also introduced and driven around using keyboard control.

In this chapter, we will expand TurtleBot's capabilities by giving the robot vision. The chapter begins by describing 3D vision systems and how they are used to map obstacles within the camera's field of view. The four types of 3D sensors typically used for TurtleBot are shown and described, detailing their specifications. A 2D vision system is also introduced for TurtleBot 3.

Setting up the 3D sensor for use on TurtleBot 2 is described and the configuration is...
