Robot Operating System Cookbook

By: Kumar Bipin

Overview of this book

This book will leverage the power of ROS with an introduction to its core and advanced concepts through exciting recipes. You will get acquainted with the use of different synchronous and asynchronous communication methods, including messages, services, and actions. You will learn how to use the various debugging and visualization tools used in development and how to interface sensors and actuators with the ROS framework. Firstly, you will get to grips with ROS simulation frameworks, such as Gazebo and RotorS for modeling and simulating any physical robot and virtual environment. You will also cover mobile robotics, micro-aerial vehicles, and robotic arms, which are the leading branches of robotic applications. Robot Operating System Cookbook will also guide you in the development of an autonomous navigation framework for both mobile robots and micro-aerial vehicles. Finally, you will explore ROS-Industrial, an open source project that extends the advanced capabilities of ROS software to manufacturing industries.

Autonomous navigation of mobile robots – avoiding obstacles

The ROS navigation stack is the most powerful software package that allows mobile robots to move from one place to another safely. The goal of the navigation stack is to produce a safe path, in other words, a collision-free path for the robot to execute by processing the data from sensors and the environment map. One of the great functionalities of the navigation stack is obstacle avoidance. We can easily view this feature by adding an object in front of the moving robot in Gazebo.

Getting ready

A few predefined shapes or obstacles can be added in Gazebo by using the Insert model option from GUI. The navigation stack detects the obstacle and automatically creates...
