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.

Introducing Crazyflie 2.0


Crazyflie is a quadrotor that is classified as a micro air vehicle (MAV), as it only weighs 27 grams and can fit in your hand. It was developed and is manufactured by Bitcraze AB and comes as a kit—ready to assemble with no soldering required. The designers of Crazyflie wanted to build a small flying electronic board that had minimal mechanical parts. They provide it and support it as an open source development platform, encouraging others to contribute to both Crazyflie hardware and software development. For this book, the Crazyflie 2.0 model was used for testing purposes, but the Crazyflie ROS software indicates that it is compatible with both Crazyflie 1.0 and 2.0 models embedded with stock firmware. The Crazyflie2.0 model is shown in the following figure and is the model referred to in the rest of this chapter:

The size of the assembled Crazyflie is 92 mm (3.6 inches) square motor to motor and 29 mm (1.1 inches) high.
