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.

Summary


This chapter introduced the TurtleBot 2 robot and described how to load the necessary software for this TurtleBot. The Gazebo simulator was used to show the capability of ROS to control the TurtleBot 2 in simulation.

To control a real TurtleBot 2 and allow it to roam autonomously, it is desirable to set up a wireless communication between a remote computer and the TurtleBot's netbook. The explanation given in this chapter will allow you to set up the network and remotely control TurtleBot 2.

The various methods to control TurtleBot 2 were presented. Teleoperation from the remote computer is one of the common methods used to control the robot's motion. A Python script was shown, which, when executed, will make the TurtleBot 2 move in a straight line. This chapter also covered the use of rqt tools to send commands to TurtleBot 2 and monitor them.

An important aspect of this chapter is that the TurtleBot 2 can be controlled in simulation or in a real environment with the same commands...
