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 TurtleBot 3


At ROSCon 2016, a conference for developers, the TurtleBot 3 was introduced. TurtleBot 3 is a mobile robot designed and manufactured by ROBOTIS that is particularly suitable for education and hobbyist use. For remote control, the TurtleBot 3 must be connected via Wi-Fi to a network and a remote computer.

These ROS-based robots are smaller than the TurtleBot 2 described previously in this chapter. The two TurtleBot3 models are shown in the following image:

TurtleBot 3 Burger and Waffle

The Burger model has a small footprint with a wheelbase of 160 mm (6.29 in) and height of 192 mm (7.5 in) with a Laser Distance Sensor (LDS) on its top level. According to the specifications, the Burger version can carry 15 kg (33 lbs) and run for 2.5 hours. The Waffle model is larger with a wheelbase of 278mm (10.9 in) but with a height of only 141mm (5.5 in).

The TurtleBot 3 website describes the models presently available: http://turtlebot3.robotis.com/en/latest/.
