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 automatic docking


TurtleBot 2 has the capability of finding its docking station and moving to that station for recharging as described in the tutorial available at: http://wiki.ros.org/kobuki/Tutorials/Automatic%20Docking.

According to the tutorial, the TurtleBot must be placed in line-of-sight of the docking station since the robot homes on the station using an infrared beam. The docking station will show a solid red light when it is powered up. If the TurtleBot finds the station and docks properly, the red light will turn to blinking green when charging and solid green when TurtleBot's battery is fully charged.

Make sure that the minimal launch is active and the TurtleBot is within the line-of-sight to the docking station. On the remote computer, type the following command:

$ roslaunch kobuki_auto_docking minimal.launch

Then, in another terminal window, type the following command to cause the TurtleBot to start the search for the docking station:

$ roslaunch kobuki_auto_docking...
