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.

Analyzing the ROS computation graph

ROS creates a computational network where all the processes are connected. Any process in the system can access this network, interact with other processes, observe the information that they are sending, and transmit data to the network. In general, they perform collaborative computational tasks.

Getting ready

This computation network can be called the computation graph. The basic concepts in the computation graph are ROS nodes, master, parameter server, messages, topics, services, and bags. Each concept in the computational graph has a specific contribution in different ways.

The ROS communication-related packages, including core client libraries, such as roscpp and rospython, and the implementation...
