ROS Robotics By Example, Second Edition - Second Edition

By: Carol Fairchild, Lentin Joseph, Dr. Thomas L. Harman

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.

Moving the real TurtleBot 3


As with TurtleBot 2, TurtleBot 3 has a number of ways to move using ROS. In the following section, we will present moving TurtleBot around using a keyboard.

To operate the TurtleBot 3 on you network, perform the following steps:

  1. Make sure that the TurtleBot battery is charged.

  2. Turn on the TurtleBot and make sure that green lights illuminate on the OpenCR board and the Raspberry Pi. A red light should also be lit on the Raspberry Pi. The green light on the USB2LDS board should also be lit.

  3. Make sure the TurtleBot has room to move on the floor.

  4. Connect the remote computer to the network for TurtleBot and start communicating.

This procedure will be used each time you set up to use the ssh command from the remote computer terminal. The TurtleBot 3 password will be required after using the ssh command described in the next section.

Note

While operating the TurtleBot 3, be aware that the buzzer will emit a warning sound when the battery is running low. The buzzer will sound...
