ROS Robotics By Example, Second Edition - Second Edition

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.

TurtleBot 2 hardware specifications


Before driving the real TurtleBot around, it would be useful to understand the capabilities of the robot in terms of its possible speed, turning capability, carrying capacity, and other such properties. With this information, you can plan the motion and speed of TurtleBot and design interesting applications. The specifications here are taken from the information provided for the Kobuki base by the Yujin Robot company. Their website for general information and specifications can be found at the following site:

A user's guide for the Kobuki base is included at the following site:

The base has a rechargeable battery that powers the motors turning the wheels. The netbook has its own battery but is not charged when the TurtleBot is moving on its own. There are a number of sensors in the base.

In the previous examples of teleoperation, the TurtleBot linear speed in the forward...
